Picture/gesture password protection

Abstract:

A method is provided for identifying a strength of an input picture password formed by performing a sequence of gestures relative to a picture. The method includes storing, in a memory device, a crowdsource history of picture passwords each of which include a picture and a sequence of gestures on the picture. The method further includes generating, by a processor-based demography-based pattern usage assessment generator, a demography-based pattern usage assessment by analyzing the crowd source history. The method also includes providing, by a user-perceptible indication device, an indication of the strength of the input picture password in accordance with the demography-based pattern usage assessment.
