Understanding the ginormous Philippines data breach
> As serious as the info above is, it’s only scratching the surface. Per the reports linked to earlier, there’s also biometric data relating to fingerprints in the system. This contains columns names such as these:> PRINT_FLAG, FINGER_INFO, FINGER_TOPO_COORD, QUALITY, MATCHING_FINGER> The values within there can be quite detailed and I’ve no reason to think that this isn’t indeed legitimate print data uniquely and biologically identifying the owner. You don’t get to reset that stuff once it’s been released into the wild!That's one of the biggest dangers in using biometrics as a factor in authentication. Once it leaks (and keeping data safe is one of the hardest task in today's world) there is no changing, no resetting, it is out there and rendered useless at best or a vector for identity theft at worst.
