Unauthorized user prevention device and method

A system for generating a pressure signature profile and comparing the pressure signature profile to a further pressure signature profile, which system can be used as a component of a handgun safety lock, the system being comprised of:

• a pressure actuated generator of electrical signals produced in response to applied pressure, applied pressure as a function of area, and applied pressure as a function of time;
• a processing unit electrically connected to the generator,
• the processing unit having a processor for developing a pressure signature profile from the electrical signals;
• storage for storing at least one pressure signature profile;
• and
• a comparator for comparing the stored pressure signature profile to a further pressure signature profile.

A method for generating a pressure signature profile and comparing the pressure signature profile to a further pressure signature profile, of a firearm device said method comprising the steps of:

• (a) storing an authorized user's pressure signature profile in a storage area;
• (b) sensing the pressure of a user's handgrip by pressure sensors and providing pressure to a comparator;
• (c) compiling a pressure signature profile by said comparator based on the pressure sensed in step (b) with regard to:
• 1) positions of the sensors reporting a change in pressure, 2) an amount of change in pressure detected, and 3) pressure as a function of time;
• (d) comparing the pressure signature profile compiled in step (c) with the pressure, signature profile stored in step (a) to determine whether there is a matching profile;
• (e) enabling access to a device if the comparison in step (d) matches to indicate that a user is authorized.
