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 characteristics selected from a set of characteristics, the method comprising: presenting, via a programmed processor of the device, a displayed image including a plurality of designatable cells, each designatable cell containing a symbol having a plurality of characteristics from said set of characteristics, each of said characteristics of said combination of characteristics being contained within at least one designatable cell; varying, via the programmed processor of the device, the image between an initial presentation and a subsequent presentation such that the plurality of characteristics contained in a designatable cell in the subsequent presentation is different from the plurality of characteristics 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 characteristics, and determining whether the identified plurality of characteristics comprises said combination of characteristics making up the validation code for said user.
