Security experts are warning that making the popular ‘V’ hand sign in high-quality selfies could expose your fingerprints to theft. Chinese security expertLi Chang demonstrated how fingerprints can easily be copied from close-up photos taken within 1.5 metres, using AI and photo software to sharpen blurry images.
While modern high-definition cameras make this possible, experts say stealing fingerprints is still quite difficult. The process depends heavily on good lighting, sharp focus and clear image quality. Thieves would also likely need multiple photos to get an accurate copy. To stay safe, blur or edit your fingertips before posting selfies online.
