15/818910

Inventors:

- DALLAS TX, US
Chong Lee - Allen TX, US

International Classification:

G06F 21/36

Abstract:

A method and associated computing device. A first arrangement of numeric characters - is displayed, on a touch screen of the computing device, for an entry of a confidential sequence of numeric characters by a user during display of the first arrangement of the numeric characters - in ten respective regions of the touch screen. Each region includes (i) a unique numeric character and (ii) a graphical design that does not include the unique numeric character. The graphical design in each region is a different graphical design in each region. Each region has a closed exterior boundary and is totally filled with the graphical design consisting of a background pattern or no pattern. A graphical characteristic is instantiated differently for each numeric character displayed in the first arrangement. User touches are received on the displayed first arrangement of the confidential sequence of numeric characters to authenticate or authorize the user.

International Classification:

G06F 21/60

US Classification:

Abstract:

A method and system for performing a security authentication. A name of a user, N sequences of digits, and encrypted values respectively corresponding to the digits in the N sequences are transmitted to a destination device. Each sequence includes a same M unique digits and begins with a different digit, wherein N≧2 and M≧3. N encrypted values of the transmitted encrypted values are received, wherein an Ireceived encrypted value of the N received encrypted values corresponds to one of the digits selected by the user, at an electronic device, from a respective Isequence of the N sequences (I=1, 2, . . . , N). N digits respectively corresponding to the received N encrypted values are determined. The determined N digits form a number matching a PIN associated with the name of the user, which authenticates the user to access a resource.
