Abstract:
1. A method of validating a user of a device, in which data representative of a validation code for a user is stored in a storage device, said data comprising a combination of symbols selected from a set of symbols, the method comprising: presenting, via a programmed processor of the device, a displayed image including a plurality of designatable cells in which said set of symbols is distributed between said designatable cells such that each designatable cell contains a plurality of symbols from said set of symbols, each of the plurality of symbols being independent of others of the plurality; varying, via the programmed processor of the device the image between an initial presentation and a subsequent presentation such that the plurality of symbols contained in a designatable cell in the subsequent presentation is different from the plurality of symbols contained in the designatable cell in the initial presentation; and validating, via the programmed processor of the device a user in a validation routine by detecting designation by the user of the device of a combination of said designatable cells in a presented image, each such designation identifying a plurality of symbols, and determining whether the identified plurality of symbols comprises said combination of symbols making up the validation code for said user.
