Feeling is Believing: a location limited channel based on grip pattern biometrics and cryptanalysis

Publication Date


We use grip pattern based biometrics as a location limited channel to achieve pre-authentication in a protocol that sets up a secure cannel between two handheld devices. The protocol efficiently calculates a shared secret key from biometric data using quantization and cryptanalysis. The protocol is used in an application where grip pattern based biometrics is used to control access to police hand guns.
