Abstract

Disclosed is a new password pattern design method that is based on combining different diagrams and pages. The design is for password entry on a touch screen device such as a smart phone, tablet computer, or electronic transaction screen that uses an unobservable keypad entry scheme, which protects the entry from theft through visual observation.

Unlock Touch Screen for Password or PIN Input using Changeable Screen Pages

As the use of mobile and touchscreen devices grows, and use in public areas increases, password security with the risk of a password being stolen simply by someone observing keystrokes or using hidden recording devices (e.g., cameras) is a growing concern. The loss of a password can compromise all data stored on or accessed through that device.

A method is needed to increase the security of password and personal identification number (PIN) entry on mobile devices, tablets, or other touchscreen devices that require the use of a keypad for access.

The novel solution is a design for password entry on a touch screen device such as a smart phone, tablet computer, or electronic transaction screen that uses an unobservable keypad entry scheme. Implementing this method makes it difficult for a person to identify another user's numeric password or PIN simply through visual observation or recording.

Although the owner must still keep passwords and PINs as confidential information, this method protects the details at the time of user entry.

This design enables the user to easily memorize a password, as it can be shorter, but by algorithm, the result can be more keystrokes than would be used to just enter the password/PIN in a pre-configured sequence.

The known predefined password pattern is comprised of three components: password/PIN, time, and page. The user entering the password/PIN needs to know the pattern to enter on a specific page. The pattern is constant and known to user. The page number on which the user can enter the valid pattern is dynamic. That page is changed based in the current time. The user defines the time. The user only needs to remember the defined pattern to enter the password/PIN, and the time algorithm.

The touch screen has 100 possible pages (from 00 to 99) when it is in locked status, and each page display is the same
(i.e. includes date, time, and nine points). The user can pass the authentication by entering the correct password/PIN on the correct page based on the current time. User cannot pass the authentication when the password pattern is correct (as it is observable) but the page number on which it is entered is...
