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.
Claims18
A method for identifying a strength of an input picture password formed by performing a sequence of gestures relative to a picture, the method comprising:
- storing, in a memory device, a crowdsource history of picture passwords, each of the picture passwords including a picture and a sequence of gestures on the picture;
- generating, by a processor-based demography-based pattern usage assessment generator, a demography-based pattern usage assessment to develop demography-based rules determined from the crowd source history as well as user cultural and language backgrounds encompassing distinct gestures so that each gesture of each sequence of gestures is compared to commonly used hand movement and demography-based patterns derived from the user cultural and language backgrounds to determine a strength of each gesture;
- and
- providing an indication of the strength of the input picture password based on the strength of each gesture within the input picture password.
