1. A device for user authentication, comprising:

  • a multi-touch interface producing input signals in response to multiple points of simultaneous physical contact;

    a processor in data communication with the multi-touch interface; and

    a memory, in data communication with the processor, configured to store data that represents a pattern of physical contact associated with a user and storing instructions which, when executed by the processor, cause the processor to perform operations comprising;

    comparing the input signals to the data that is stored in the memory that represents the pattern of physical contact associated with the user,determining from the comparison whether physical contact represented by the input signals matches the pattern of physical contact associated with the user, andproducing a signal value that indicates a successful authentication of the user and that identifies the user upon determining that the physical contact represented by the input signals matches the pattern of the physical contact associated with the user.
