An investigative reporter has found significant evidence that US police regularly use dead persons' biometrics to access their devices.Separate sources close to local and federal police investigations in New York and Ohio, who asked to remain anonymous as they weren't authorized to speak on record, told the Forbes reporter that it was now relatively common for fingerprints of the deceased to be depressed on the scanner of Apple iPhones.FBI forensics specialist Bob Moledor detailed for Forbes the first known case of police using a deceased person's fingerprints in an attempt to get past the protections of Apple's Touch ID technology. The report notes that it is entirely legal for police to use the technique, even if there might be some ethical quandaries to consider. Marina Medvin, owner of Medvin Law, said that once a person is deceased, they no longer have a privacy interest in their dead body. That means they no longer have standing in court to assert privacy rights.Controversially, it even can be used for face recognition – including 3D solutions.Marc Rogers, researcher and head of information security at Cloudflare, told Forbes he'd been poking at Face ID in recent months and had discovered it didn't appear to require the visage of a living person to work.Whilst Face ID is supposed to use your attention in combination with natural eye movement, so fake or non-moving eyes can't unlock devices, Rogers found that the tech can be fooled simply using photos of open eyes. That was something also verified by Vietnamese researchers when they claimed to have bypassed Face ID with specially-created masks in November 2017, said Rogers.
