Abstract
The present disclosure generally relates to methods for enrolling a user of an electronic device and authentication the user of the electronic device. The electronic device comprising a biometry sensor for acquiring sensing signals representative of a biometric feature, and a processor for computing a verification representation based on said sensing signals. The electronic device further includes a secure module isolated from said processor for computing an encrypted representation of said enrollment representation.
Claims20
A method for enrolling a user of an electronic device comprising:
- a biometry sensor for acquiring sensing signals representative of a biometric feature;
- a processor for computing an enrollment representation based on said sensing signals;
- a secure module isolated from said processor for computing an encrypted representation of said enrollment representation, wherein said method comprises:
- acquiring sensing signals representative of a candidate's biometric feature;
- based on said sensing signals, determining an enrollment representation by said processor;
- determining, by said secure module, an encrypted representation of said enrollment representation;
- storing, in said secure module, said encrypted representation;
- when said encrypted representation has been established, providing a success signal indicative of successful encryption to said processor,
- in response to receiving the success signal, storing, by the processor, the enrollment representation.

A method for authenticating a user of an electronic device comprising:
- a biometry sensor for acquiring sensing signals representative of a biometric feature;
- a processor for computing a verification representation based on said sensing signals;
- and,
- a secure module isolated from said processor for computing an encrypted representation of said enrollment representation, wherein said method comprises:
- acquiring sensing signals representative of a candidate's biometric feature;
- determining, by said processor, a verification representation based on said sensing signals;
- comparing, said verification representation with at least one stored enrollment representation;
- sending, when a match is found between said verification representation and a stored enrollment representation, said enrollment representation to said secure module;
- determining, by said secure module, an encrypted representation of said enrollment representation and comparing said encrypted representation with at least one stored encrypted representation;
- when a match is found between said encrypted representation and a stored encrypted representation, providing a pass signal indicative of successful authentication.
