A method of protecting the credential security on touch screens is proposed. The method uses random number sequences that are displayed in a random area. The first sequence is displayed randomly, and the subsequent sequences are centered to the position of your last press to reduce the movement of fingers. The method leverages the maximum randomness to ensure the security of credentials and keep it from peeping by others.

A method of protecting passwords from being peeped on touch screens

Mobile devices are often equipped with a password to prevent unauthorized use of, or access to the devices. However, the known methods of entering simple passwords are not secure. The unauthorized user can easily obtain the password when the user is entering the password in the public occasions. If the security of password entering on mobile devices cannot be guaranteed, there will be huge risks in our work and life.

The most common method currently is generating dynamic password to trigger the second authorization, which has limited secure , but with many annoying features and terrible user experience. Therefore, a smart method to ensure secure password entering is a must.

A group of integer sequences appear on the phone screen consecutively and then disappear in a few seconds. The sequence might be in any shape, circle, square, line, and so on. In this demo, circles are used to display the sequences.

Each digit of your phone password is encrypted by your pre-defined rule. Each of the sequences contain a group of random integers, which contains the encrypted digit of the phone password.

The user needs to select each digit of the password on each sequence and click the location of the digit to unlock the phone.

This invention possesses the following advantages:

Guarantee the security on mobile devices. Protect users' passwords from peepers. Even if users enter passwords in public places with peepers around, peepers still cannot get the passwords which are protected by this invention. It will minimize the huge risks of economic loss and the loss of confidentiality

when users have to enter passwords in public places.

Confuse peepers by combining number input and path input. Peepers won't get the real purpose of users' actions. Peepers can hardly realize that the users are entering passwords (number input) for bank accounts or email accounts. Peepers may assume that users are just using gestures to unlock the mobile devices.

Protect users' passwords by making the password input region dynamically changes each time. Therefore, even if peepers notice the path input. When

they draw the same path, they still get the wrong password.

Improve user experience by making it easier for users to draw the path. The passwo...
