Worse than just data loss
Sure, El Reg is a technology site, so the article focusses on "hacking" - getting into someone else's smartphone and so on. The ability to take a photo of someone's hands and then generate usable "fingerprints" has more problems than just giving someone access to those dodgy selfies you have.
What if I can make a pair of gloves with all ten fingerprints from someone else on them, and then go and commit a crime and leave "my" fingerprints for SoCO to find?
