Tips from a tech expert on spotting AI-generated fakes
With the upsurge in deepfakes and how easy it is to create them we talk spotting fakes and how you can stay vigilant. The widespread availability and ease of use of image and video generators powered by artificial intelligence (AI) means what you see on the internet may not be what it seems. These programs and apps can create increasingly realistic-looking pictures, videos, and sound with only a few simple text prompts. In one recent example, a popular indie rock band that had more than a million monthly listeners on Spotify turned out to be AI-generated. In another case, officials in the U.S. warned of attempts to use AI tools to impersonate Secretary of State Marco Rubio. The Canadian Anti-Fraud Centre also recently warned about a rise in AI-generated voice messages being used to impersonate high-profile figures to extort victims for money and personal data. Even CTV News Ottawa was subject to impersonation using these kinds of tools. Following a report about an online scam that affected a local family, a fake version of our report circulated online, changing the words our anchors said to make it sound like they were advertising the scam in a positive light. Technology analyst and journalist Carmi Levy told CTV Morning Live that, for now, most AI-generated images and videos have imperfections that can give the game away. 'The two words that we usually use that seem to work for now are 'lean in.' So, when you're watching a video, slow it down, lean in and watch for what we like to call 'tells' that give away the fact that it's not real, it is synthetically generated, AI-created,' he said. Some things to watch out for include how the subject of the video moves. 'The movement might not be as smooth, it might be kind of stop-and-start,' said Levy. 'There might be little hitches here and there; sometimes the lips, the audio doesn't quite match what you're seeing on the individual's face.' The lighting or shading of the video might not look natural, or there might be other artefacts that seem out of place, Levy says. 'For example, if someone puts their arm around the back of somebody, there might be a placement issue or extra pieces; sometimes there are additional fingers or not enough fingers.' Levy warns, however, that these tools are becoming more sophisticated and are better able to replicate a realistic scene. 'With each new generation of these video generator apps, they get better and so it gets even harder to tell that something was AI-created. In fact, the new version of Veo, Veo 3, is so good that for a lot of people, even if they lean in, it's increasing difficult to tell,' he said. The federal government says rapid advances in AI have underscored the risks associated with the technology. 'The Government is taking actions to ensure that AI is developed in a safe and responsible manner,' a spokesperson for Innovation, Science and Economic Development Canada said in a statement to CTV News Ottawa. 'Just last November, the Government of Canada launched the Canadian Artificial Intelligence Safety Institute with the mandate to advance scientific understanding of the risks associated with the most advanced AI systems, develop measures to reduce those risks, and build trust to foster AI innovation. 'In addition, the government also launched a Voluntary Code of Conduct on the Responsible Development and Management of Advanced Generative AI Systems in September of 2023. The Code calls on AI developers and managers to take risk-mitigation measures such as developing and implementing reliable and freely available methods to detect content generated by their AI system. Greater transparency on AI generated content can help protect Canadians against AI-enabled scams and fakes. The Government is protecting Canadians from fraud and impersonation, including cases involving AI, and will continue to explore all options to strengthen these protections.' Levy says when you see something online, before sharing it, ask questions and make sure it's coming from a trustworthy source. 'How do you tell if it's real or not real? You check the source. You make sure it's coming from a legitimate source that you can trust. In many cases, if you can't trace it back to its origin, you should start with the assumption that it's not real,' he said. 'That's what I do; I start cynically and require the content to prove to me that it is, in fact, real.'

Man who survived a stroke in his 40s says it was caused by a 'seemingly harmless' turn of the head: 'Awareness is survival'
Carmi Levy was enjoying a bike ride on a sunny day in 2013 when a seemingly harmless turn of the neck caused a tear in his artery. Later that evening, he became paralyzed on one side and unable to speak clearly. Levy's wife — recognizing he was having a stroke — had their kids call 9-1-1 immediately. 'I probably wouldn't be here today if my wife hadn't known what was happening right when I collapsed,' Levy says. 'She knew about FAST from her training as a teacher, and she routinely discussed it at home so we were prepared if we suspected a stroke.' This article is for informational purposes only and is not a substitute for professional medical advice, diagnosis or treatment. Contact a qualified medical professional before engaging in any physical activity, or making any changes to your diet, medication or lifestyle. This article was originally published in 2024. Many people aren't as lucky as Levy whose wife knew the critical importance of calling for medical help without delay. In the months after his stroke, he had many conversations with stroke survivors who had brushed off their symptoms and refused offers of medical assistance. Fears of long wait times at the ER even led one victim to ignore their partner's pleas to call 9-1-1. 'You should never fear a wasted trip to the hospital,' says Levy. 'It's better to be safe now than sorry later. With something as irreversible as a stroke, you don't want to take that risk.' June is Stroke Awareness Month in Canada. Stroke is a leading cause of adult disability in Canada, with one stroke occurring roughly every five minutes. According to the Heart & Stroke Foundation, approximately one million Canadians are living with stroke, with 108,000 strokes occurring each year. Knowing the signs of stroke can help increase your chances of a better recovery and even save your or someone else's life. Heart & Stroke launched its FAST campaign in 2014 to provide people with a simple tool for recognizing the most common signs of stroke: Face – is it drooping? Arms – can you raise both? Speech – Is it slurred or jumbled? Time to call 9-1-1 right away. Since the introduction of FAST 10 years ago, awareness has greatly increased, with a 2024 showing the number of Canadians who can name at least two FAST signs of stroke has doubled. However, new data reveals that only seven out of 10 Canadians know what a stroke can look like. According to Katie White, director of health systems at Heart & Stroke, reducing the time between the onset of stroke and arrival at a hospital can mean the difference between life and death, and also lower the chance of a lifelong disability. 'Anyone witnessing or experiencing the signs of stroke should call 9-1-1 or local emergency medical services (EMS) right away,' White tells Yahoo Canada. 'Lifesaving treatment begins the second you make that call." While awareness of FAST has increased, there are still gaps, with Heart and Stroke's poll showing disparities depending on gender, age, place of birth and race or ethnicity. "Many ethnically diverse communities are less likely to be familiar with the FAST signs of stroke," says White. 'We don't know for sure why these differences exist, but we're exploring targeted strategies to address these inequities.' This includes translating FAST materials into multiple languages and developing toolkits specifically for First Nations communities. The poll also showed that older Canadians are more familiar with the signs of stroke and more likely to take action, perhaps due to the belief that only older adults can be affected by stroke. As a stroke survivor in his 40s, Levy is no stranger to this misconception. 'At least one member of my medical team said she was surprised to see someone so young and healthy present as a stroke victim,' he says. 'There were a lot of raised eyebrows and a lot of discussion around the root cause of my stroke, because of my age.' White says that with three out of 10 Canadians unable to recognize the most common signs of stroke, there's still a lot of work to do. 'There are still not enough Canadians who recognize the signs and know to call 9-1-1 right away if they witness or experience them,' she says. Levy's experience underscores the importance of stroke awareness for everyone, regardless of age or health status. "I never had 'stroke' on my bingo card before it happened to me," he reflects. "I realize how easily things could have gone the other way if I hadn't been surrounded by a family that knew what to look for – and what to do when they saw it.' 'If so much as one person hears my story, learns, and acts, then that's everything to me,' he adds. 'Awareness is survival.'
