US 2012/0256723 A1 · RANDOM LOCATION AUTHENTICATION

Abstract

An authentication string, such as a password, consists of characters. Each of the characters in the authentication string is randomly associated with a defined location on a device. For example, an area on a touch screen can be associated with a character in the authentication string. When a user selects a location associated with the character, feedback is provided that identifies the character. When the user selects a location that is not associated with the character, feedback is provided that does not identify the character. If the user responds by indicating that the associated location matches the character, the character is authenticated. If the user responds by indicating that a location not associated with the character is a match, the character is not authenticated. This process is then repeated for each character in the authentication string.

Dependent claims

A method comprising:

a. getting an authentication string, the authentication string comprising a character;
b. defining a plurality of locations on a device;
c. randomly associating at least one of the plurality of locations on the device with the character;
d. providing a feedback to a user when the user selects one of the associated locations, the feedback identifying the character associated with the location;
e. providing a feedback to the usr when the user selects a location not associated with the character, the feedback not identifying the character associated with the location;
f. receiving an indication from the user that the feedback for the selected associated location matches the character;
and
g. in response to receiving the indication that the feedback for the selected associated location matches the character and not receiving an indication to the feedback when the user selects a location that is not associated with the character, authenticating the character.

A system comprising;

an authentication system operable to get an authentication string, the authentication string comprising a character, define a plurality of locations on a device, and authenticate the character in response to receiving an indication that a feedback for the selected associated location matches the character and not receiving an indication to the feedback when a user selects a location that is not associated with the character;
a randomizer operable to randomly associate at least one of the plurality of locations on the device with the character;
a feedback system operable to provide the feedback to the user when the user selects one of the associated locations, the feedback identifying the character associated with the location, provide the feedback to the user when the user selects a location not associated with the character, the feedback not identifying the character associated with the location;
and
a user interface operable to receive the indication from the user that the feedback for a selected associated location matches the character.
