Simplified authentication method for controls on persons
The invention proposes a method for controls on persons in possession of a document comprising a machine-readable zone containing a document number and an electronic chip in which an authentication biometric is stored, comprising: at a first step ( 100 ), acquiring ( 120 ) a biometric datum, acquiring ( 110 ) the document number by reading the machine-readable zone, and recording ( 130 ), in a memory ( 20 ), the number linked with the biometric datum, and at a second step ( 200 ), acquiring ( 210 ) a biometric, from said biometric datum retrieving ( 220 ), in the memory, the number of the identity document corresponding to the person, accessing the content of the chip and retrieving the authentication biometric datum ( 240 ), and performing authentication ( 250 ) of the person by comparing the authentication biometric datum with a biometric datum of the person.
1. A method for controls on persons in possession of an identity document comprising a machine-readable zone containing a document number and an electronic chip in which an authentication biometric datum of the person is stored, the method comprising:
at a first step implemented by a first control device,
acquiring a first biometric datum on a biometric feature of the person,
acquiring the number of the person's identity document by reading the machine-readable zone of the identity document, and
recording, in a remote memory, the number linked with the person's biometric datum, and
at a second step implemented by a second control device,
acquiring a second biometric datum on the same biometric feature of the person as the one on which the first biometric was acquired,
from the second biometric datum, retrieving, in the memory, the number of the identity document corresponding to the person's biometric feature,
from the number of the person's identity document, accessing the content of the electronic chip of the identity document and retrieving the authentication biometric datum, and
performing biometric authentication of the person by comparing the authentication biometric datum stored in the chip with a biometric datum acquired by the second control device.
2. The method according to claim 1 , wherein the biometric datum acquired by the second control device for the biometric authentication step is the second biometric datum, or another biometric datum acquired on a different biometric feature.
3. The method according to claim 1 , wherein the retrieval step of the number of the identity document in the memory comprises:
comparison of biometric data stored in the memory with the second biometric datum, and
selection of at least one number corresponding to at least one biometric datum having a similarity rate with the second biometric datum higher than a predetermined threshold.
4. The method according to claim 3 , wherein if more than one identity document number has been selected, the step to access the content of the chip of the identity document comprises the implementation of an attempt to open the chip with each selected number until opening of the chip.
5. The method according to claim 3 , wherein the first step also comprises the recording in the remote memory, of at least one additional datum linked with the number of the identity document and the first biometric datum,
and the retrieval step of the number of the identity document comprises the preselection, in the memory, of biometric data and document numbers associated with said additional datum.
6. The method according to claim 5 , wherein at the second step, the additional datum is acquired by the second control device, or is known to the second control device by being associated therewith.
7. The method according to claim 1 , wherein the biometric feature on which the first and second biometric data are acquired is selected from the group comprising: one or more fingerprints, one or more iris scans, the person's face, the venous network of one or more fingers or of one or both hands, or the respective sizes of phalanges or fingers.
8. The method according to claim 1 , wherein step comprises the acquisition of a plurality of biometric data on different biometric features of the person, and the recording of the document number linked with each of the biometrics.
9. The method according to claim 1 , wherein the identity document is a passport, and:
at the first step, the passport is presented open on the page of the machine-readable zone to the first control device to implement the acquisition step of the passport number, and
at the second step, the passport is presented closed to the second control device to implement the step to access the content of the chip.
10. The method according to claim 9 , wherein at the second step, the passport is presented in any orientation relative to the second control device.
11. The method according to claim 1 , wherein the first control device is physically remote from the second, and is a personal device owned by the person from among a mobile telephone, tablet computer and personal computer or a kiosk installed within one same infrastructure as the second control device.
12. A computer readable medium comprising code instructions to implement the first step of the method according to claim 1 , comprising steps of:
acquiring and processing an image of a person's biometric feature to obtain a biometric datum,
reading a machine-readable zone of an identity document to acquire a document number, and
recording, in a remote memory, the number linked with the biometric datum, when executed by a processor.
13. A computer readable medium comprising code instructions to implement the second step of the method according to claim 1 , comprising steps of:
acquiring and processing an image of a person's biometric feature, to obtain a biometric datum,
from said biometric datum, retrieving, in a memory, an identity document number corresponding to the biometric feature from which the biometric datum was acquired, and
from the number of the person's identity document accessing the content of the electronic chip of the identity document and retrieving an authentication biometric datum contained in said chip,
when executed by a processor.
14. A system for controls on persons, comprising:
a memory,
a first control device comprising a module to read a machine-readable zone of an identity document, a module to acquire a biometric datum, and a communication interface with the memory, and
a second control device comprising a module to acquire a biometric datum, a reader adapted to access the content of a chip of an identity document, and a communication interface with the memory,
wherein it is adapted to implement the method according to claim 1 .
15. The system for controls on persons according to claim 14 , wherein the first control device is a personal electronic device owned by the person, from among a personal computer, mobile telephone and tablet computer.
