Google's Project Abacus aims to replace password-based authentication systems
Project Abacus does its magic by analyzing usage patterns. It looks at things such as the way you type, the way you move, the way you swype, and the apps that you usually use. On top of that, Abacus also uses biometric authentication tools such as voice and face detection. By combining all of those signals, the system tries to identify if the person currently using the device is actually the owner.
The trick here is getting all of these things to work together. While face detection can be easily fooled (at least for the moment), it's hard for a potential perpetrator to also mimic your voice and the way you use a device. Google says that Project Abacus is actually harder to fool than conventional authentication systems such as 4-digit passwords or fingerprint readers.
Today in a live demo on the Google I/O stage, Project Abacus was able to tell the difference between two separate users. Looking into the future, the system might actually go through some safety protocols when it detects that the device is not being used by its owner. At the moment, Google's ATAP team has yet to disclose when Project Abacus might make its way to commercial devices.
