The present invention relates to an autonomous electronic device for authenticating the identity of persons by biometric recognition, and to the associated data management methods.

Biometric recognition makes it possible to accurately determine an individual's identity based on their natural characteristics. It is commonly done using computer systems.

Based on a pre-existing collection of 10 data on the individuals to be recognized, biometric recognition can be broken down into two stages:

A) Digitization of the characteristics of the individual. This is done using specialized sensors such as, for example, fingerprint reader, color or infrared camera, 3D camera.

B) Comparison of the data collected with those relating to known individuals, looking for a similarity beyond a predefined threshold. The IT resource requirements at this stage depend on the application framework:

For a small population (eg when it comes to recognizing the owner of an electronic device or smart card) all operations can be performed in situ with relatively small computers. powerful, such as desktops or smartphones

For a large population (for example, the database of a large company or that of a state police force), the calculations are performed by specialized remote computers, due to the size of the data to be scanned. and the complexity of operations. Thus, large-scale biometric recognition depends on the availability of a reliable telecommunication system connecting the acquisition terminals and the data processing centers.

The present invention consists of an autonomous electronic device combining them for a large population.

steps A and 'B,

The accompanying drawings illustrate

The invention:

FIG. 1 represents the device of the invention and FIG. 2 represents a variant of this device.

With reference to these drawings, the device comprises the following basic elements:

"A means of data storage (4)

A calculation module (3) • A means of entering the declared identity of the subject (1)

A means of acquiring biometric data (2)

All the data allowing the recognition of each of the individuals of the target population are included on the storage means (4), so as to allow autonomous operation.

The biometric data are ordered in memory according to the identity of the people.

The users are required to state their identity using a device provided for this purpose (1) before the actual biometric recognition, thus facilitating the search in the database.

After retrieving the recording relating to the individual to be recognized, the biometric data acquired using the device provided for this purpose (2) are compared on-site (3) with those obtained from the memory.

According to a preferred embodiment, the device bears the following specificities:

The data stored on the memory means and are protected against counterfeiting by a computer signature which allows the operator to ensure the authenticity and completeness of said data.

-3Only the mathematical characterizations of this data are stored. These characterizations are chosen so as to allow the recognition of an individual while limiting the size of the data to be stored, and can at the same time make it possible to make the data anonymous.

For example, instead of storing photos of individuals, we can store the ratios of the distances between the main elements of their face.

A set of sensors with different biometric parameters is used, to mitigate errors, based on several criteria, such as, for example, the shape of the face, the pattern of the iris or even fingerprints.

A history of the authentication operations performed is kept for tracking purposes. Also, the device can be equipped with a geolocation system, such as GPS, to associate precise geolocation with each of these operations.

Furthermore, a variant of the device of the invention has, in addition to the other basic components, a control interface (5), allowing the user to configure the device and / or to learn about its operation and its functions. operations.

Similarly, a variant provides for the inclusion of a means of connection to a remote server such as, for example, Bluetooth, Wi-Fi or GSM, so as to transmit, as soon as possible, the report of the operations carried out, in order to feed a common central database.

In a low-cost embodiment, the subject's identity entry means is a pptic reader of identity documents, such as identity cards, passports or badges.

-4In this case, a key data, taken directly from said document, serves as a benchmark for the ordering of the biometric data in memory, and a hashing of the information available on the document is associated with the biometric data of the individual, so, to be able to authenticate identification documents while ensuring the anonymity of users.

Figures 3 and 4 show variants of an embodiment of an identification document reader, in cross section. With reference to these drawings, the reader consists of a housing (6), comprising:

A slot (7) for inserting documents (8)

An optical sensor (9), capable of fast g ^ and-angle and close-focusing shots

A source of radiation (10)

According to a variant of this identification document reader, the housing also contains a second optical sensor (11) and a second radiation source (12) in order to be able to scan both sides of the document.

According to another variant of this identification document reader, the box also contains a spring push-button system (13) making it possible to detect the insertion of a document and optionally to push it back to facilitate extraction after reading.
