  • BLACKLISTING OF FREQUENTLY USED GESTURE PASSWORDS
    Publication number: 20150128233
    Abstract: A method of maintaining a blacklist for gesture-based passwords is provided. A data store of vectors corresponding to gestures is maintained on a blacklist server. Upon receiving a new gesture based password, an electronic device converts the password to a vector and forwards that vector to the blacklist server. The blacklist server assigns the vector to one of a cluster of vectors each having low distance from one another. If the increase in the occurrences of the number of vectors in the cluster results in a blacklist threshold being exceeded, the cluster of vectors is inputted to the blacklist. A notification can be sent back to the electronic device if the forwarded vector is on the blacklist or is inputted to the blacklist.

  • Blacklisting of frequently used gesture passwords
    Patent number: 8615793
    Abstract: A method of maintaining a blacklist for gesture-based passwords is provided. A data store of index values corresponding to gestures is maintained on a blacklist server. Upon receiving a new gesture based password, an electronic device converts the password to an index value and forwards that index value to the blacklist server. The blacklist server increases an occurrence of the received index value by one in a data store and if the increase results in a blacklist threshold being exceeded, the index value is inputted to the blacklist. A notification can be sent back to the electronic device if the forwarded index value is on the blacklist or is inputted to the blacklist.
