Abstract
A finger sensing apparatus may include an integrated circuit (IC) substrate, an array of finger sensing elements on the IC substrate, and encryption circuitry on the IC substrate cooperating with the array of finger sensing elements for encrypting a user template comprising finger template data and at least one user credential. The at least one user credential may enable another device, such as a host platform, to perform at least one protected operation.
Claims22
The finger sensing apparatus comprising:
- an integrated circuit (IC) substrate;
- an array of finger sensing elements on said IC substrate;
- encryption circuitry on said IC substrate cooperating with said array of finger sensing elements for encrypting a user template comprising finger template data and at least one user credential;
- match circuitry on said IC substrate for performing finger matching based upon at least the user template;
- and
- credential release circuitry on said IC substrate and cooperating with said match circuitry for releasing the at least one user credential based upon finger matching.
An electronic device comprising:
- a housing;
- an integrated circuit (IC) substrate carried by said housing;
- an array of finger sensing elements on said IC substrate;
- encryption circuitry on said IC substrate cooperating with said array of finger sensing elements for encrypting a user template comprising finger template data and at least one user credential;
- match circuitry on said IC substrate for performing finger matching based upon at least the user template;
- and
- credential release circuitry on said IC substrate and cooperating with said match circuitry for releasing the at least one user credential based upon finger matching;
- and
- a host platform carried by said housing and being enabled to perform at least one protected operation based upon a release of the at least one user credential, and said host platform performing at least one prematch function.
A method for finger sensing comprising:
- encrypting a user template comprising finger template data and at least one user credential using encryption circuitry on an IC substrate cooperating with an array of finger sensing elements also on the IC substrate;
- performing finger matching based upon at least the user template using match circuitry also on the IC substrate;
- and
- releasing the at least one user credential based upon finger matching using credential release circuitry on the IC substrate and cooperating with the match circuitry.
