Abstract
A method for biometrically recognizing individuals, comprising the following steps: performing at least two biometric recognitions based on separate sets of biometric characteristics detected on an individual during at least one first and one second detection operations; detecting a third set of biometric characteristics during the first detection and a fourth set of biometric characteristics during the second detection; verifying that the third set of biometric characteristics matches the fourth set of biometric characteristics. A corresponding enrolment method and a device to implement these methods.
Claims9
A method for biometrically recognizing individuals, comprising the following steps:
- performing a first biometric recognition based on a first set of biometric characteristics detected on an individual during at least one first detection operation;
- performing a second biometric recognition based on a second set of biometric characteristics detected on this individual during a second detection operation, the second set of biometric characteristics being separate from the first set of biometric characteristics;
- characterised in that the method comprises the following steps:
- detecting a third set of biometric characteristics during the first detection and a fourth set of biometric characteristics during the second detection;
- verifying that the third set of biometric characteristics matches the fourth set of biometric characteristics;
- considering the individual as recognized in the event that the biometric recognitions succeed and if the third set of biometric characteristics matches the fourth set of biometric characteristics.
A method for automatically enrolling an individual, in view of subsequently performing a biometric recognition, by recording a first set of biometric characteristics detected on an individual during a first detection operation and a second set of biometric characteristics detected on this individual during a second detection operation, the second set of biometric characteristics being separate from the first set of biometric characteristics;
- the method comprising the following steps:
- detecting a third set of biometric characteristics during the first detection and a fourth set of biometric characteristics during the second detection;
- verifying that the third set of biometric characteristics matches the fourth set of biometric characteristics;
- considering the enrolment valid if the third set of biometric characteristics matches the fourth set of biometric characteristics.
