Lights could be the future of the internet and data transmission

Anonymous — Tue, 25 Jul 2023 14:38:40 +0000

New internet technologies are being rapidly refined, and LED-based communication links are expected to be used in services and scenarios including Light-fidelity (Li-Fi), underwater communications, moderate- to high-speed photonic connections and various 鈥業nternet of Things鈥� (IoT) devices.

A study, led by the Universities of Surrey and Cambridge and published in the journal Nature Photonics, has investigated how to release high-speed photonic sources using materials known as metal-halide perovskites. These semiconductors are studied with LEDs for their excellent optoelectronic properties and low-cost processing methods.

鈥淚oT devices have the potential to add significant value to industry and the global economy,鈥� said corresponding author Dr Wei Zhang from the 探花直播 of Surrey. 鈥淚n this market, costs and compatibility are often prioritised over data transmission speed and scientists are looking for alternative ways to reduce energy consumption per bit and improve compactness while simultaneously working on improving the speed of data connection.

鈥淚n our study, we have shown how metal-halide perovskites could provide a cost-efficient and powerful solution to make LEDs which have enormous potential to increase their bandwidths into the gigahertz levels.

鈥淥ur investigations will accelerate the development of high-speed perovskite photodetectors and continuous wave-pumped perovskite lasers, opening up new avenues for advancements in optoelectronic technologies.鈥�

鈥淭his is a significant step toward perovskite light sources for next-generation data communications,鈥� said co-first author Hao Wang, a PhD candidate in Cambridge鈥檚 Department of Engineering. 鈥淚t also paves the way for the integration of perovskites with micro-electronics platforms, presenting new opportunities for seamless integration and advancement in the field of data communications.鈥�

探花直播project involved researchers from Oxford, Bath, Warwick, UCL, EMPA and UESTC.

Existing infrastructure will be unable to support demand for high-speed internet

sc604 — Tue, 26 Apr 2022 15:00:00 +0000

探花直播researchers, from the 探花直播 of Cambridge and BT, have established the maximum speed at which data can be transmitted through existing copper cables. This limit would allow for faster internet compared to the speeds currently achievable using standard infrastructure, however it will not be able to support high-speed internet in the longer term.

探花直播team found that the 鈥榯wisted pair鈥� copper cables that reach every house and business in the UK are physically limited in their ability to support higher frequencies, which in turn support higher data rates.

While full-fibre internet is currently available to around one in four households, it is expected to take at least two decades before it reaches every home in the UK. In the meantime, however, existing infrastructure can be improved to temporarily support high-speed internet.

探花直播results, reported in the journal Nature Communications, both establish a physical limit on the UK鈥檚 ubiquitous copper cables, and emphasise the importance of immediate investment in future technologies.

探花直播Cambridge-led team used a combination of computer modelling and experiments to determine whether it was possible to get higher speeds out of existing copper infrastructure and found that it can carry a maximum frequency of about 5 GHz, above the currently used spectrum, which is lower than 1 GHz. Above 5 GHz however, the copper cables start to behave like antennas.

Using this extra bandwidth can push data rates on the copper cables above several Gigabits per second on short ranges, while fibre cables can carry hundreds of Terabits per second or more.

鈥淎ny investment in existing copper infrastructure would only be an interim solution,鈥� said co-author Dr Anas Al Rawi from Cambridge鈥檚 Cavendish Laboratory. 鈥淥ur findings show that eventual migration to optical fibre is inevitable.鈥�

探花直播twisted pair鈥� where two conductors are twisted together to improve immunity against noise and to reduce electromagnetic radiation and interference 鈥� was invented by Alexander Graham Bell in 1881. Twisted pair cables replaced grounded lines by the end of the 19th century and have been highly reliable ever since. Today, twisted pair cables are standardised to carry 424 MHz bandwidth over shorter cable lengths owing to deeper fibre penetration and advancement in digital signal processing.

These cables are now reaching the end of their life as they cannot compete with the speed of fibre-optic cables, but it鈥檚 not possible to get rid of all the copper cables due to fibre鈥檚 high cost. 探花直播fibre network is continuously getting closer to users, but the connection between the fibre network and houses will continue to rely on the existing copper infrastructure. Therefore, it is vital to invest in technologies that can support the fibre networks on the last mile to make the best use of them.

鈥淗igh-speed internet is a necessity of 21st century life,鈥� said first author Dr Ergin Dinc, who carried out the research while he was based at Cambridge鈥檚 Cavendish Laboratory. 鈥淚nternet service providers have been switching existing copper wires to high-speed fibre-optic cables, but it will take between 15 and 20 years for these to reach every house in the UK and will cost billions of pounds. While this change is happening, we鈥檝e shown that existing copper infrastructure can support higher speeds as an intermediate solution.鈥�

探花直播Cambridge researchers, working with industry collaborators, have been investigating whether it鈥檚 possible to squeeze faster internet speeds out of existing infrastructure as a potential stopgap measure, particularly for rural and remote areas.

鈥淣o one had really looked into the physical limitations driving the maximum internet speed for twisted pair cables before,鈥� said Dinc. 鈥淚f we used these cables in a different way, would it be possible to get them to carry data at higher speeds?鈥�

Using a mix of theoretical modelling and experimentation, the researchers found that twisted pair cables are limited in the frequency they can carry, a limit that鈥檚 defined by the geometry of the cable. Above this limit, around 5 GHz, the twisted pair cables start to radiate and behave like an antenna.

鈥� 探花直播way that the cables are twisted together defines how high a frequency they can carry,鈥� said Dr Eloy de Lera Acedo, also from the Cavendish, who led the research. 鈥淭o enable higher data rates, we鈥檇 need the cables to carry a higher frequency, but this can鈥檛 happen indefinitely because of physical limitations. We can improve speeds a little bit, but not nearly enough to be future-proof.鈥�

探花直播researchers say their results underline just how important it is that government and industry work together to build the UK鈥檚 future digital infrastructure, since existing infrastructure can handle higher data rates in the near future, while the move to a future-proof full-fibre network continues.

探花直播work is part of an ongoing collaboration between the Cavendish, the Department of Engineering, BT and Huawei in a project led by Professor Mike Payne, also of the Cavendish Laboratory. 探花直播research was also supported by the Royal Society, and the Science and Technology Facilities Council, part of UK Research and Innovation.

Researchers have shown that the UK鈥檚 existing copper network cables can support faster internet speeds, but only to a limit. They say additional investment is urgently needed if the government is serious about its commitment to making high-speed internet available to all.

Researchers to track impact of lockdown on alcohol, gambling and pornography use

cjb250 — Mon, 11 May 2020 23:16:03 +0000

探花直播UK was first placed on lockdown in response to the coronavirus pandemic on 23 March. Only essential businesses were allowed to remain open and everyone was told to stay at home, only to venture out for exercise and shopping.

Almost overnight, people鈥檚 lives were up-ended, with some people working from home while others have lost their jobs or been furloughed. People who live by themselves have suddenly found themselves with no social contact other than virtual.

To find out what impact this has had on people鈥檚 behaviour, Dr Valerie Voon from the 探花直播 of Cambridge and Prof Henrietta Bowden-Jones, Director of the National Problem Gambling Clinic, London, have launched an online survey, HabiT 鈥� Habit Tracker 鈥� asking about changes in habits during lockdown, specifically quantifying alcohol, smoking, and online use of gambling, gaming and pornography.聽探花直播habit tracker survey is available聽online. All responses will be anonymous.

探花直播survey is short, only taking 10 minutes to complete. 探花直播researchers are keen to hear from both those people who do not consider themselves to be vulnerable or exhibit problem behaviours and those who have struggled in the past or are struggling now.

鈥淲e expect to see an increase in these behaviours across the UK in response to the unprecedented circumstances we find ourselves in,鈥� says Dr Voon. 鈥淚n many cases, these changes will be people鈥檚 strategies for coping with the anxiety and stress caused by the pandemic and lockdown and, we hope, won鈥檛 have a long term impact if the behaviour can be controlled.

鈥淔or some people who might already have been struggling with or have a history of addiction these increased habits could prove problematic. 探花直播same goes for those people who find themselves in difficult circumstances, for example having lost their job or facing financial difficulties, or are struggling to cope with the lockdown. These more vulnerable individuals may find their behaviour has a more marked longer lasting effect, triggering an alcohol relapse, for instance, or reigniting a gambling addiction.鈥�

Survey respondents may also take part in CrusH, an alcohol avoidance online training game for smartphones being developed which can be accessed as part of the survey.

Five tips for coping during the lockdown

Keep active: exercise outdoors and take part in online exercise workouts
Keep in touch with people socially online 鈥� try FaceTime, Skype or Zoom so that you see people
Maintain some regular structure: sleep, wake, work
Don't spend too much time looking at news
Use this as an opportunity to try something new 鈥� try baking, learning a new language, writing that novel you always dreamed of writing

Is the lockdown leading us to drink more alcohol or spend more time gambling online or watching pornography? Researchers today launch a survey aimed at tracking how our habits have changed in response to our forced isolation.

We expect to see an increase in these behaviours across the UK in response to the unprecedented circumstances we find ourselves in... For some people who might already have been struggling with or have a history of addiction these increased habits could prove problematic

Create a WTO-equivalent to oversee the internet, recommends new report

Anonymous — Wed, 12 Feb 2020 00:08:50 +0000

探花直播findings, which have been published by the UK-China Global Issues Dialogue Centre at Jesus College Cambridge, draw on a conference attended by international experts including former Australian Prime Minister Kevin Rudd and representatives from Google, Facebook, Huawei, Alibaba, United Nations Conference on Trade and Development, the ITU, and OECD.

探花直播global communications system 鈥� including the internet, smartphone access, and the Internet of Things 鈥� allows near-universal communication and supports almost every aspect of the modern economy. 探花直播report argues that just as the capabilities of communications infrastructures are being amplified by artificial intelligence (AI) and other technologies, we are becoming more aware of the risks of direct attacks and splintering, and the threat of distrust.

Professor Peter Williamson, Chair of the UK-China Global Issues Dialogue Centre, said: 鈥� 探花直播world faces a series of complex issues involving data and communications which go beyond national or bilateral deals. They potentially threaten free and open trade, easy and reliable communication, data flows and connectivity.鈥�

Conference attendees widely agreed that the world would bene铿乼 from better orchestrating knowledge about communications infrastructures, providing a shared picture of issues, threats and opportunities, based on deep technical expertise. One of the most important recommendations in this report is that the first step in creating a WTO-equivalent for data flows would be to set up a Global Communications Observatory. 探花直播Observatory could play an important role in uncovering potential risks of new data and communications technologies, such as loss of privacy or opportunities for data tampering, and proposing solutions.

鈥淲e need a global institution comparable to those in climate change, finance, health, development or refugees. At the moment, there is no obvious place for multilateral negotiations over issues such as data privacy or cybersecurity,鈥� added Professor Williamson.聽聽

鈥淲e propose using the Intergovernmental Panel on Climate Change (IPCC) as a model, as that has hugely influenced intergovernmental processes of negotiation and action around climate change.鈥�

Creating the Global Communications Observatory would require support from the main telecommunications companies, mobile providers and platforms, sharing relevant data on network performance and patterns. It could in time become a condition of public licenses, and use of spectrum, that they share key data on the state of networks. It would be likely to need joint funding by the main nations involved in global communications, with contributions from the main businesses (operators, platforms and manufacturers), so that it could o铿€er a living picture of the state and prospects of the infrastructures on which we all depend.

Designed to be as high profile and accountable as the IPCC, the Global Communications Observatory would draw on existing processes and use techniques pioneered by the IPCC for large-scale expert participation in analysis and assessments. It would deliver regular reports on key trends and emergent issues, and present accessible visualisations of the state of communications networks. In time, it could gain a formal status and a duty to report into the G20 and G7.

探花直播internet needs an international World Trade Organization (WTO)-style body to protect and grow it as one of the world鈥檚 unique shared resources: a communications infrastructure that is open, free, safe and reliable, concludes a new report published today.

Online hate speech could be contained like a computer virus, say researchers

fpjl2 — Tue, 17 Dec 2019 17:37:13 +0000

探花直播spread of hate speech via social media could be tackled using the same 'quarantine'聽approach deployed to combat malicious software, according to 探花直播 of Cambridge researchers.

Definitions of hate speech vary depending on nation, law and platform, and just blocking keywords is ineffectual: graphic descriptions of violence need not contain obvious ethnic slurs to constitute racist death threats, for example.

As such, hate speech is difficult to detect automatically. It has to be reported by those exposed to it, after the intended "psychological harm" is inflicted, with armies of moderators required to judge every case.

This is the new front line of an ancient debate: freedom of speech versus poisonous language.

Now, an engineer and a linguist have published a proposal in the journal Ethics and Information Technology that harnesses cyber security techniques to give control to those targeted, without resorting to censorship.

Cambridge language and machine learning experts are using databases of threats and violent insults to build algorithms that can provide a score for the likelihood of an online message containing forms of hate speech.

As these algorithms get refined, potential hate speech could be identified and "quarantined". Users would receive a warning alert with a "Hate O'Meter" 鈥撀爐he hate speech severity score 鈥撀爐he sender's name, and an option to view the content or delete unseen.

This approach is akin to spam and malware filters, and researchers from the 'Giving Voice to Digital Democracies' project believe it could dramatically reduce the amount of hate speech people are forced to experience. They are aiming to have a prototype ready in early 2020.

"Hate speech is a form of intentional online harm, like malware, and can therefore be handled by means of quarantining," said co-author and linguist Dr Stefanie Ullman. "In fact, a lot of hate speech is actually generated by software such as Twitter bots."

"Companies like Facebook, Twitter and Google generally respond reactively to hate speech," said co-author and engineer Dr Marcus Tomalin. "This may be okay for those who don't encounter it often. For others it's too little, too late."

"Many women and people from minority groups in the public eye receive anonymous hate speech for daring to have an online presence. We are seeing this deter people from entering or continuing in public life, often those from groups in need of greater representation," he said.

Former US Secretary of State Hillary Clinton recently told a UK audience that hate speech posed a "threat to democracies", in the wake of many women MPs citing online abuse as part of the reason they will no longer stand for election.

While in a Georgetown 探花直播 address, Facebook CEO Mark Zuckerberg spoke of "broad disagreements over what qualifies as hate" and argued: "we should err on the side of greater expression".

探花直播researchers say their proposal is not a magic bullet, but it does sit between the "extreme libertarian and authoritarian approaches" of either entirely permitting or prohibiting certain language online.

Importantly, the user becomes the arbiter. "Many people don't like the idea of an unelected corporation or micromanaging government deciding what we can and can't say to each other," said Tomalin.

"Our system will flag when you should be careful, but it's always your call. It doesn't stop people posting or viewing what they like, but it gives much needed control to those being inundated with hate."

In the paper, the researchers refer to detection algorithms achieving 60% accuracy 鈥撀爊ot much better than chance. Tomalin's machine learning lab has now got this up to 80%, and he anticipates continued improvement of the mathematical modeling.

Meanwhile, Ullman gathers more 'training data': verified hate speech from which the algorithms can learn. This helps refine the 'confidence scores'聽that determine a quarantine and subsequent Hate O'Meter read-out, which could be set like a sensitivity dial depending on user preference.

A basic example might involve a word like 'bitch': a misogynistic slur, but also a legitimate term in contexts such as dog breeding. It's the algorithmic analysis of where such a word sits syntactically - the types of surrounding words and semantic relations between them - that informs the hate speech score.

"Identifying individual keywords isn't enough, we are looking at entire sentence structures and far beyond. Sociolinguistic information in user profiles and posting histories can all help improve the classification process," said Ullman.

Added Tomalin: "Through automated quarantines that provide guidance on the strength of hateful content, we can empower those at the receiving end of the hate speech poisoning our online discourses."

However, the researchers, who work in Cambridge's Centre for Research into Arts, Humanities and Social Sciences (CRASSH), say that 鈥撀燼s with computer viruses 鈥撀爐here will always be an arms race between hate speech and systems for limiting it.

探花直播project has also begun to look at "counter-speech": the ways people respond to hate speech. 探花直播researchers intend to feed into debates around how virtual assistants such as 'Siri' should respond to threats and intimidation.

探花直播work has been funded by the International Foundation for the Humanities and Social Change.

Artificial intelligence is being developed that will allow advisory 'quarantining'聽of hate speech in a manner akin to malware filters 鈥撀爋ffering users a way to control exposure to 'hateful content'聽without resorting to censorship.

European research network aims to tackle problematic internet use

cjb250 — Mon, 08 Oct 2018 23:39:34 +0000

As the internet has become an integral part of modern life and its use has grown, so too has its problematic use become a growing concern across all age groups. It has provided a new environment in which a wide range of problematic behaviours may emerge, such as those relating to gaming, gambling, buying, pornography viewing, social networking, 鈥榗yber-bullying鈥� and 鈥榗yberchondria鈥�, which can have mental and physical health consequences.

探花直播newly created European Problematic Use of the Internet (EU-PUI) Research Network was formed in response to the emerging public health importance of problematic internet use and is funded through a 鈧�520,000 grant from COST (European Cooperation in Science and Technology). 探花直播network鈥檚 aims include identifying key genetic, psychological and social factors that lead people to disordered online behaviours including excessive video gaming, pornography viewing and use of social networks.

Professor Naomi Fineberg, Consultant Psychiatrist from the 探花直播 of Hertfordshire and Chair of the new network, said: 鈥淧roblematic Use of the Internet is a serious issue. Just about everyone uses the internet, but information on problem use is still lacking. Research has often been confined to individual countries, or problematic behaviours such as Internet gaming. So we don鈥檛 know the real scale of the problem, what causes problematic use, or whether different cultures are more prone to problematic use than others.鈥� 聽

探花直播network, which includes 123 experts from 38 countries across Europe, has today published its manifesto in the journal European Neuropsychopharmacology, setting out the research priorities to help the scientific and clinical communities understand and tackle problematic internet use. These include:

Age- and culture-appropriate assessment tools to screen, diagnose and measure the severity of different forms of problematic internet use
Understanding its impact on health and quality of life
Clarifying the possible role of genetics and personality features
Consideration of the impact of social factors in its development
Developing and testing effective interventions, both to prevent and to treat its various forms
Identifying biomarkers, including digital markers, to improve early detection and intervention

Professor Fineberg adds: 鈥淭here鈥檚 no doubt that some of the mental health problems we are looking at appear rather like addiction, such as online gambling or gaming. Some lean towards the OCD end of the spectrum, like compulsive social media checking. But we will need more than just psychiatrists and psychologists to help solve these problems. We need to bring together a range of experts, such as neuroscientists, geneticists, child and adult psychiatrists, those with lived experience of these problems and policymakers, in the decisions we make about the internet.

鈥淲e need to remember that the Internet is not a passive medium; we know that many programmes or platforms earn their money by keeping people involved and by encouraging continued participation; and they may need to be regulated 鈥� not just from a commercial viewpoint, but also from a public health perspective.鈥�

Dr Sam Chamberlain, Consultant Psychiatrist from the 探花直播 of Cambridge, who is leading research priorities for the network, added: "Despite dedicated research leading to some breakthroughs in our understanding of the psychology and biology that underpins these聽behaviours, we still don鈥檛 know enough about the risk factors for problematic internet use.

鈥� 探花直播current level of evidence has to be increased to improve our ability to diagnose problems and predict an individual鈥檚 prognosis, as well as to develop effective interventions to help affected individuals and those at greatest risk.鈥�

Cambridge launches UK鈥檚 first quantum network

sc604 — Wed, 13 Jun 2018 10:46:23 +0000

探花直播鈥榤etro鈥� network provides secure quantum communications between the Electrical Engineering Division at West Cambridge, the Department of Engineering in the city centre and Toshiba Research Europe Ltd (TREL) on the Cambridge Science Park.

Quantum links are so secure because they rely on particles of light, or photons, to transmit encryption keys through the optical fibre. Should an attacker attempt to intercept the communication, the key itself changes through the laws of quantum mechanics, rendering the stolen data useless.

Researchers have been testing the ultra-secure network for the last year, providing stable generation of quantum keys at rates between two and three megabits per second. These keys are used to securely encrypt data, both in transit and in storage. Performance has exceeded expectations, with the highest recorded sustained generation of keys in field trials that include encryption of data in multiple 100-gigabit channels.

探花直播Cambridge network is a project of the Quantum Communications Hub, a consortium of eight UK universities, as well as private sector companies and public sector stakeholders. 探花直播network was built by Hub partners including the 探花直播鈥檚 Electrical Engineering Division and TREL, who also supplied the Quantum Key Distribution (QKD) systems. Further input came from ADVA, who supplied the optical transmission equipment, and the 探花直播鈥檚 Granta Backbone Network, which provided the optical fibre.

探花直播UK Quantum Network is funded by the Engineering and Physical Sciences Research Council (EPSRC) through the UK鈥檚 National Quantum Technologies Programme. It brings together concentrations of research excellence and innovation, facilitating greater collaboration between the two in development of applications that exploit the unique formal guarantee of security provided by quantum physics.

鈥淭hrough this network, we can further improve quantum communications technologies and interoperability, explore and develop applications and services, and also demonstrate these to potential end users and future customers,鈥� said Professor Timothy Spiller of the 探花直播 of York, and Director of the Quantum Communications Hub.

鈥� 探花直播development of the UK Quantum Network has already led to a much greater understanding of the potential of this technology in secure applications in a range of fields, in addition to bringing new insights into the operation of the systems in practice,鈥� said Professor Ian White from Cambridge鈥檚 Department of Engineering. 鈥淚 have no doubt that the network will bring many benefits in the future to researchers, developers and users.鈥�

鈥淲orking with the Quantum Communications Hub, Cambridge and ADVA has allowed us to develop an interface for delivering quantum keys to applications,鈥� said Dr Andrew Shields, Assistant Director of Toshiba Research Europe Ltd. 鈥淚n the coming years, the network will be an important resource for developing new applications and use cases.鈥�

鈥淒evelopment of the network has brought together in the Quantum Communications Hub partnership many world-class researchers and facilities from both UK universities and industry,鈥� said Dr Liam Blackwell, Head of Quantum Technologies at EPSRC. 鈥淭his is a reflection of EPSRC鈥檚 commitment to investing in UK leadership in advanced research and innovation in quantum technologies.鈥�

Online tool can measure individuals鈥� likelihood to fall for internet scams

sc604 — Wed, 04 Apr 2018 10:21:58 +0000

探花直播psychometric tool, developed by researchers at the Universities of Cambridge and Helsinki, asks participants to answer a range of questions in order to measure how likely they are to respond to persuasive techniques. 探花直播test, called Susceptibility to Persuasion II (StP-II) is freely available and consists of the StP-II scale and several other questions to understand persuadability better. A brief, automated, interpretation of the results is displayed at the end of the questionnaire.

探花直播results of the test can be used to predict who will be more likely to become a victim of cybercrime, although the researchers say that StP-II could also be used for hiring in certain professions, for the screening of military personnel or to establish the psychological characteristics of criminal hackers. Their results are reported in the journal PLOS One.

鈥淪cams are essentially like marketing offers, except they鈥檙e illegal,鈥� said paper鈥檚 first author Dr David Modic from Cambridge鈥檚 Department of Computer Science and Technology. 鈥淛ust like in advertising, elements of consumer psychology and behavioural economics all come into the design of an online scam, which is why it鈥檚 useful to know which personality traits make people susceptible to them.鈥�

Modic and his colleagues at the 探花直播 of Exeter designed an initial version of the test five years ago that yielded solid results but was not sufficiently detailed. 探花直播new version is far more comprehensive and robust.

鈥淲e are not aware of an existing scale that would measure all the constructs that are part of StP-II,鈥� said Modic, who is also a senior member of King鈥檚 College, Cambridge. 鈥淭here are existing scales that measure individual traits, but when combined, the sheer length of these scales would present the participant with a psychometric tool that is almost unusable.鈥�

探花直播questions in StP-II fall into 10 categories, measuring different traits which might make people more susceptible to fraud: the ability to premeditate, consistency, sensation seeking, self-control, social influence, need for similarity, attitude towards risk, attitude towards advertising, cognition and uniqueness. Participants are given a score out of seven in each of the ten areas.

Using a large data set obtained from a collaboration with the BBC, the researchers found that the strongest predictor was the ability to premeditate: individuals who fail to consider the possible consequences of a particular action are more likely to engage with a fraudster. However, they found that the likelihood of falling for one of the measured categories of Internet fraud is partially explained by at least one of the mechanisms in StP-II.

鈥淥ver the past ten years, crime, like everything else, has moved online,鈥� said co-author Professor Ross Anderson, also from Cambridge鈥檚 Department of Computer Science. 鈥淭his year, about a million UK households will be the victim of typical household crime, such as burglary, where the average victim is an elderly working-class woman. However, now 2.5 million households will be the victims of an online or electronic scam, where the victims are younger and more educated. Crime is moving upmarket.鈥�

鈥淪cams have been around for hundreds of years, and over the centuries, they haven鈥檛 really changed that much 鈥� the only difference now is with the internet, it requires a lot less effort to do it,鈥� said Modic.

探花直播researchers say that despite the changing demographics of crime victims, there isn鈥檛 a 鈥榯ypical victim of cybercrime. 鈥淥lder generations might be seen as less internet-savvy, but younger generations are both more exposed to scams and might be seen as more impulsive,鈥� said co-author Jussi Palom訐ki, from the 探花直播 of Helsinki鈥檚 Cognitive Science Unit. 鈥淭here isn鈥檛 a specific age range 鈥� there are many different risk factors.鈥�

鈥� 探花直播immediate benefit of StP-II is that people will get an indication of the sorts of things they should look out for 鈥� I鈥檓 not saying it鈥檚 a sure-fire way that they will not be scammed, but there are things they should be aware of,鈥� said Modic. 鈥淪tP-II doesn鈥檛 just measure how likely you are to fall for scams, it鈥檚 how likely you are to change your behaviour.鈥�
