The decision to integrate biometric detection into consumer electronics may be popular with users and shows the willingness of companies to embrace emerging technologies, but the fundamental reason for such integration boils down to one thing: an attempt to improve security. The data associated with biometric capture extends beyond a simple password or code created by the user. It actually forms part of who that person is as an individual and is quite possibly as personal as it can get, so when things go wrong, as one research company will point out at this week's RSA, it raises a lot more eyebrows than a simple password breach. According to a new report, a number of Android devices are failing to protect the data of users that is captured through integrated biometric sensors.
