Abstract

A system and a computer program product are provided for identifying a strength of an input picture password formed by performing a sequence of gestures relative to a picture. The system includes a memory device for storing a crowdsource history of picture passwords formed by tracking a plurality of picture passwords used to authenticate a plurality of users. Each of the plurality of users has a respective user profile. The system further includes a processor-based demography-based pattern usage assessment generator for generating a demography-based pattern usage assessment by analyzing the crowd source history and the user profile of the plurality of users. The system also includes a user-perceptible indication device for providing an indication of the strength of the input picture password in accordance with the demography-based pattern usage assessment.

Claims

1-14. -14. (canceled)

15. A computer program product for identifying a strength of an input picture password formed by performing a sequence of gestures relative to a picture, the computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to perform a method comprising:

storing, in a memory device, a crowdsource history of picture passwords formed by tracking a plurality of picture passwords used to authenticate a plurality of users, each of the plurality of users having a respective user profile;

generating, by a processor-based demography-based pattern usage assessment generator, a demography-based pattern usage assessment by analyzing the crowd source history and the user profile of the plurality of users; and

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.

16. A system for identifying a strength of an input picture password formed by performing a sequence of gestures relative to a picture, the system comprising:

a memory device for storing a crowdsource history of picture passwords formed by tracking a plurality of picture passwords used to authenticate a plurality of users, each of the plurality of users having a respective user profile;

a processor-based demography-based pattern usage assessment generator for generating a demography-based pattern usage assessment by analyzing the crowd source history and the user profile of the plurality of users; and

a user-perceptible indication device for providing an indication of the strength of the input picture password in accordance with the demography-based pattern usage assessment.

17. The system of claim 16, wherein the demography-based pattern usage assessment is determined from a demography that includes at least one of a language style, an age group, a country, an experience level, a gender, and a culture.

18. The system of claim 16, wherein the demography-based pattern usage assessment is determined from a pattern usage that includes an image main point of interest reference, a contour, a common pattern, a predictable pattern, a circular pattern, and a direction.

19. The system of claim 16, further comprising a rule generator for generating a set of rules for judging password strength based on at least one of the crowdsource history and the demography-based pattern usage assessment.

20. The system of claim 19, wherein the set of rules are generated further based on user inputs to applications that involve users making one or more gestures.
