Everyone loves to hate one thing that is under fire now when it comes to the Internet. That is the user password.Actually it's been under fire for a long time.
In an ideal world, people would use a 1long string composed of completely random characters, numbers and symbols. Furthermore, a unique password would be used for every site or application the user uses. Unfortunately,the more complex they become, the more people are likely to forget them. The longer the passwords, the more easily forgotten they are. Therefore, people use the same password for every service or application. It is a no-10 and essentially defeats the purpose of a password.
Google is trying to kill off the user password. at least on Android devices by introducing the Trust API, which does what simple passwords cannot. It gives developers a framework for securing their applications using a number of security systems and metrics(衡量标准) on the device. A Trust Score will be generated based on the metrics the device gathers and will allow or deny access to applications based on whether or not your Trust Score is high enough.The Trust Score will be generated based on metrics like your device location, face scanning and fingerprint, and the things like your typing speed or the way you speak. Taken one at a time, these metrics are not very secure. But taken together, these metrics will help define the real "you".
Passwords have been around since the dawn of computing and although the security of systems has been improved, they haven't done much to improve the usability of systems. Google appears to have the best of both worlds - a highly secure system that end users won't even notice. Maybe that never- ending conflict between security and convenience will be able to take a break once the trust system comes out.
