Abstract
A computer-implemented method entails capturing a digital fingerprint of a finger using a fingerprint-capturing device, collecting pressure measurements using pressure sensors associated with the fingerprint-capturing device as the finger contacts the fingerprint-capturing device, determining a finger-sensor contact direction from the pressure measurements and storing the finger-sensor contact direction in association with the digital fingerprint for subsequent biometric authentication.
Claims20
A computer-implemented method comprising:
- capturing a digital fingerprint of a finger using a fingerprint-capturing device;
- collecting pressure measurements using pressure sensors associated with the fingerprint-capturing device as the finger contacts the fingerprint-capturing device;
- determining a finger-sensor contact direction from the pressure measurements;
- and
- storing the finger-sensor contact direction in association with the digital fingerprint for biometric authentication, wherein the biometric authentication succeeds upon recapturing the digital fingerprint with the associated finger-sensor contact direction.
The method as claimed in claim further comprising storing a first finger-sensor contact direction with a first digital fingerprint to define a first biometric authentication profile and storing a second finger-sensor contact direction with a second digital fingerprint to define a second biometric authentication profile, wherein user authentication matching the first biometric authentication profile grants access to all first set of device functions whereas user authentication matching the second biometric authentication profile grants access to a second set of the device functions.
A non-transitory computer-readable medium comprising instructions in code which when loaded into a memory and executed by a processor of a computing device cause the computing device to:
- capture a digital fingerprint of a finger using a fingerprint-capturing device;
- collect pressure measurements using pressure sensors associated with the fingerprint-capturing device as the finger contacts the fingerprint-capturing device;
- determine a finger-sensor contact direction from the pressure measurements;
- and
- store the finger-sensor contact direction in association with the digital fingerprint for biometric authentication, wherein the biometric authentication succeeds upon recapturing the digital fingerprint with the associated finger-sensor contact direction.
A computing device comprising:
- a fingerprint-capturing device for capturing a digital fingerprint of a finger;
- pressure sensors associated with the fingerprint-capturing device to collect pressure measurements as the finger contacts the fingerprint-capturing device;
- wherein the processor is configured to determine a finger-sensor contact direction from the pressure measurements and to cause the memory to store the finger-sensor contact direction in association with the digital fingerprint for biometric authentication, wherein the biometric authentication succeeds upon recapturing the digital fingerprint with the associated finger-sensor contact direction.
