The idea is a good one: Use the cellphone camera to take a selfie and employ it as another login authentication credential.
Both MasterCard and LogMeOnce have introduced a type of selfie authentication. The MasterCard process is very straightforward: If someone is buying a product from a participating merchant, the customer will get a push notification to the mobile device, which opens the selfie authentication app.
Users are then asked to blink (to show that they are living people and not just holding up a photo) and snap a picture.
