Definitions
- the present invention relates to the generation of public identity for authentication or identification of an individual using an electronic device.
- the identification aims to make it possible to know the identity of an entity, for example using an identifier which can be a user name or a network identifier (telephone number for example).
- Authentication verifies the identity of an entity to allow access to services or resources.
- Authentication or identification regularly uses a server storing data relating to entities, ie individuals having previously undergone a so-called registration (or registration) phase with said server to be delivered, when authentication or identification, any right (issuing a driver's license, a ticket, compensation, authorization to access a room, authorization to access a service, implementation of a service, electronic payment, etc.).
- the data traditionally used for the registration of individuals with the server are personal data, most often alphanumeric, such as passwords, addresses of electronic devices used by individuals (eg IP addresses), identities and / or others.
- the data used can be relatively complex from the point of view of the individuals. For example, the longer a password contains characters, the more reliable it will be, but the more difficult it will be for an individual to memorize.
- a communicating object such as smart card, smart phone, digital tablet or other
- this object can be used by its wearer in a reliable and secure way, while remaining ergonomic in its use by its wearer.
- Biometric data may be used in association with a communicating object to ensure the uniqueness of the individual carrying the object.
- a biometric passport constitutes such a secure identification object.
- the registration server may contain only weak links between the biometric data of the wearer and his identity; for example, document FR-A-2 867 881 may be referred to, likewise the biometric data may be stored only in the object of the wearer without sharing with a base.
- the reading of the biometric data from the identification object is subject to mutual authentication between the security element of the object (an electronic chip for example) and a remote server via a reader of the object ( according to the EAC protocol, for "Extended Access Control" for example), which allows verification in local mode (data in the bearer object) and / or in remote mode with information sharing with a server.
- the present invention aims to meet this need.
- the invention thus proposes a method for generating public identity for the authentication of an individual carrying an identification object comprising at least one security component, the method including an initialization phase comprising the following steps:
- said public identity being stored at the server in association with the initial encryption key.
- a first aspect of the invention consists of an initialization phase.
- This initialization phase is intended to register the individual coupled to an identification object of his choice - mobile phone, card, tablet or other - from a server that will issue a public identity.
- the public identity delivered by the server at the end of the registration phase is not significant, that is to say that it does not in any case to directly find the civil status of the holder; however, it is constructed from a strong link between the object and the biometry of the individual.
- the object of identification can not be validly used without its legitimate carrier.
- the initialization phase of the method according to the invention may furthermore comprise one or more of the following characteristics:
- the data generated by the security component of the object may be a PUU (Physical Unclonable Feature) produced by the security component of the object or a random stored in the security component of the object after draw.
- PUU Physical Unclonable Feature
- the first key is obtained by applying a signature and / or encryption function to a reference digital datum derived from the biometric data.
- This first key can be generated in the security component of the identification object or in a third party secure element
- the second key is generated in the security component of the identification object
- the initial encryption key may be generated by the security component of the identification object and then transmitted to the server; or can be generated by the server.
- a diversifier can be introduced to the initial encryption key.
- the server can introduce a diversifier to the encryption key initial prior to generating the public identity, or the first or second key can be generated by introducing a diversifier received from the server.
- the introduction of a diversifier into the encryption key during the creation of the public identity makes it possible to create a public identity specific to each service provider.
- Each digital identity thus diversified may be associated with audit functions specific to the service concerned.
- a plurality of diversified public identities may be generated and stored with the server or a plurality of servers in association with a respective diversified initial encryption key.
- the public identity or identities may also be transmitted and stored in the identification object, to later serve as identifier to a server during a request for access to services.
- the method according to the invention also comprises a verification phase of the identity of the individual carrying the identification object, the verification phase comprising the following steps:
- the comparison can be made in the security component of the identification object and / or with the server.
- a second aspect of the invention consists of a verification phase of the identity of the individual carrying the identification object. Thanks to the method of the invention, an individual does not need to decline his regal identity to attest to his right to access services for which he has registered with the object of his choice.
- the public identity built during the initialization phase can be validated on simple presentation of the object and biometry of the wearer of the object. In this context, the use of biometrics protects the anonymity of the individual.
- the invention also relates to an electronic device comprising a security component adapted to implement the steps of the method according to the invention.
- a device may further comprise means for entering a biometric data item.
- the electronic device can access a memory in which a plurality of diversified public identities are stored. The same electronic device can then serve as an identifier for accessing completely separate and hermetic services from each other.
- the invention also relates to a system for authenticating a carrier of an identification object, the system comprising an electronic device according to the invention and at least one authentication server comprising at least one public identity stored in association with initial encryption key.
- the system comprises a plurality of authentication servers each comprising at least one public identity stored in association with diversified initial encryption key.
- FIG. 1 is a flowchart of an example of an initialization phase during the implementation of the method according to the invention
- FIG. 2 is a diagram showing an example of an initialization phase that can be implemented according to one embodiment of the invention
- FIG. 3 is an example of an identification object that can be used during the implementation of the method according to the invention
- FIG. 4 is another example of an identification object that can be used during the implementation of the method according to the invention.
- FIG. 5 is a diagram showing an example of a verification phase that can be implemented according to one embodiment of the invention.
- a first aspect of the invention consists of an initialization phase.
- This initialization phase aims to register an individual in association with an identification object of his choice - mobile phone, card, tablet or other - to a server to allow the individual to be issued any right later (issuing a driver's license, a ticket, compensation, authorization to access a local, authorization of access to a service, implementation of a service, electronic payment, etc.) upon presentation of the object.
- the identification object may be a smart card, a mobile phone or any other portable object having at least one security component.
- the object of identification can be used as a loyalty card, a membership card to access services, an insurance card or a carrier bearing a sovereign identity.
- the initialization phase is illustrated in FIG.
- This initial bio biometric data Bio may be a fingerprint, an iris print or a photo of the face, ear or other discriminating part of the body of the individual, such as a tattoo, scar, or other .
- This initial bio biometric data of the individual is digitized and processed to create a reference digital data derived from the initial biometric data. Only the reference digital datum derived from the initial biometric data is stored in the security component of the object. The initial biometric data Bio does not have to be stored in the identification object. No diversion of the biometric data of an individual can therefore be operated in case of theft or loss of the object of identification.
- This initial bio biometric data is used to generate a first bio K key.
- This first key K bio can be obtained by applying, to the digital data derived from the biometric data, a signature function and / or encryption.
- a signature data P1 is generated by the security component of the object.
- This data P1 is unpredictable and depends only on the electronics of the security component of the object; it is not stored in the memory of the identification object but generated for each use as a signature of the electronic security component.
- Such a data P1 may be designated by the acronym PUF for "Physical Unclonable Feature”; it consists of a series of unpredictable binary values that are unavailable outside the object.
- the signature data P1 generated by the security component of the object can also be a random stored after drawing in the security component of the object.
- This signature data P1 of the security component of the object is used to generate a second key K HW , for example the values of the PUF or the hazard generated by the security component of the object can be used directly or after encryption to form a key.
- An initial encryption key K com can then be determined.
- This initial encryption key combines the first and second keys K bio and K HW , for example with an algorithm that uses one of the first or second keys to encrypt the other.
- This initial encryption key K ⁇ m is then used with an authentication server to register the individual with said server to be delivered, during a subsequent authentication, any right on presentation of the object and verification of the authenticity of the carrier-object couple.
- This registration step is illustrated in Figure 2 which shows the identification object 10 on the one hand and an authentication server 30 on the other hand.
- the identification object 10 chosen by the individual generated an initial encryption key K com as described with reference to FIG.
- This initial encryption key K com is communicated to the server 30 in association with a first identity Id1 of the individual.
- This first Id1 identity of the individual can be his or her identity regal identity ID or identity chosen by the individual for a particular service (Facebook ID, login fnac, ).
- the server 30 then generates a public identity Id2 by encrypting the first identity Id1 using the initial encryption key K com , for example by a standard public key infrastructure (PKI) process.
- PKI public key infrastructure
- the public identity Id2 is then stored with the server 30 in association with the initial encryption key K ⁇ m for subsequent authentication of the individual.
- the public identity Id2 may further be transmitted to the identification object 10 for storage.
- This public identity Id2 is not necessarily stored in a secure way because it is not significant as explained above.
- the initial encryption key K ⁇ m can be stored in the security component of the object 10 for subsequent use of a process known by the acronym MOC for "Match On Card".
- the identification object 10 may be a mobile phone (FIG. 3) comprising a security component 1 1 provided in a SIM card or any other embedded security element.
- the phone 10 can comprise an image capture means 12 and / or sound and / or a fingerprint reader 13, or any other biometric data input means.
- the telephone 10 also comprises communication means 14 with a cellular network; it may also include means of communication with a local network (WiFi or BT type) or near-field communication means (NFC).
- the telephone 10 can thus communicate with an authentication server to trigger access to the rights or services required by the carrier after verifying his identity.
- the identification object 10 may be a smart card (FIG. 4) comprising a security element 11 in the form of an electronic chip of the card.
- the card 10 may comprise a fingerprint reader 13 or any other means for entering biometric data.
- the card 10 is also communicating by reading the data of the chip 1 1 via an appropriate reader in contact mode and / or by non-contact communication means such as the near field model (NFC) via an antenna in the card 10.
- NFC near field model
- the card 10 can thus, for example communicate with a terminal or a telephone to trigger access to rights or services required by the wearer after verification of his identity. Verification of the identity of the individual using a smart card 10 is carried out according to the same process as that described for a telephone with reference to FIG.
- the various elements described above can be distributed differently between the identification object 10 and the authentication server 30.
- the first key K bio , the second key K HW and the initial encryption key K ⁇ m are generated in the security component of the object and only the initial encryption key is transmitted to the server 30 (as shown in FIG. 2).
- the biometric data Bio can be entered by the individual using the identification object itself; for example in the case where the identification object is a mobile phone equipped with a camera or a fingerprint reader as described below with reference to FIG. 3.
- the first key K blo can then be generated by the identification object 10 itself, by application, to the biometric data entry, an algorithm stored in the security component of the object, for example an algorithm for creating a stable digital signature as described in the document FR-A-2 925 732, then by application of an encryption function, such as a hash function for example.
- the digital data of reference derived from the entered biometric data may further be stored in the security component of the object for possible subsequent implementation of an MOC process.
- the biometric data Bio can be entered from an appropriate reader which transmits it to the identification object 10 for generating the first key K bio .
- the biometric data Bio can be transmitted directly to the identification object 10, by communication in the NFC near field for example if the object is equipped with this function, or by cellular communication or wifi if the object is equipped with this function ; the object 10 then calculates itself a digital datum of reference derived from the biometric data.
- the reference digital data derived from the biometric data Bio can be calculated in the input means and then transmitted directly to the identification object 10, by NFC near-field communication or by cellular or wifi communication.
- the second key K HW is generated in the security component of the object 10 because the data P1 is produced by the security component of the object and can not be transmitted out of the object 10.
- the initial encryption key K com is also generated in the security component of the object 10 so to limit the exchange of sensitive data.
- the initial encryption key K mm can be generated directly by the server 30 which securely receives the first and second keys K bi0 and K H w-
- the biometric data item Bio can be entered from an appropriate reader, such as a fingerprint reading terminal or a webcam installed on a PC for example.
- the first K bio key can then be generated, either by a third party secure element that has collected the biometric data Bio, or by the server 30 if the biometric data Bio or the reference digital data derived from the biometric data is transmitted thereto.
- the second key K H w generated in the security component of the object 1 0 can be transmitted out of the object. If necessary, if the initial encryption key K com was generated by the server 30, it can be transmitted to the identification object 10 to be stored there for application of a subsequent MOC process.
- the initial encryption key K mm is used by the server to create a public identity Id2 by encryption of the first identity Id1.
- the server 30 may introduce a diversifier to the initial encryption key c 0m prior to public identity generation Id2.
- the introduction of such a diversifier into the encryption key during the creation of the public identity Id2 makes it possible to create a public identity specific to the server that creates it.
- a plurality of diversified public identities Id2n can be generated and stored with one or more servers. Each of Id2n's diverse public identities is stored in association with a respective diverse initial encryption key. Each digital identity thus diversified may be associated with specific rights with the server of a specific service.
- an individual wants to use the same identification object to register with servers of different services.
- the public identity Id2 is not the same for all the services. A diversifier from the provider's server is therefore introduced during the generation of the public identity Id2.
- the diversifier can be introduced by the server 30 directly to the initial encryption key K -m before generation of the public identity Id2, that the initial encryption key K com is generated by the server or by the component security of the object which then receives the diversity of the server when it generates the initial encryption key K ⁇ m .
- the diversifier can be introduced during the generation of the first key K bio or the second key K HW , either by the server itself if it generates the first key K bio as mentioned above, or by the component of security of the object which then receives the diversifying of the server.
- the same identification object can then be used by the individual to access different services on verification of his identity.
- An individual wishes to access a particular service with which he is registered with a given Id2n public identity.
- Verification of the identity of the individual is carried out by generating a current encryption key K mm according to the same method as that described with reference to FIG. 1, based on current biometric data S / ' o' and a current data PV generated by the identification object 10 - card, phone or other. If a diversifier was introduced during the generation of the initial encryption key K com , the same diversifier is introduced in the same manner during the generation of the current encryption key K mm '.
- the digital data derived from the current biometric data Bio ' is validated internally by a comparison made in the object itself, according to an MOC process.
- the comparison between the current encryption key com 'and the initial encryption key K com can be done in the object itself by a MOC process before transmission of said current encryption key K com ' or an attestation of identity to a server or a terminal of access to the required rights or services.
- the server 30n receives the current encryption key K com 'and compares it with the initial encryption key K com . If the comparison is positive, the identity of the individual is validated and the required rights granted, otherwise the identity of the individual is refuted and the required rights denied.
- the use of diversified public identities Id2n makes it possible to limit the capacity of refutation of a service whereas the same object of identification is used by the individual.
- the same identification object can then be used by the individual to establish secure communication with a remote server, the object being able to serve as a graphical interface, a keyboard and a modem, possibly in addition to the standard exchange of data.
- information in an existing infrastructure (Bank, Risk Manager, Health Organization, etc.).
- Such an identification object can be used in the context of virtual transactions to control fraud and avoid any repudiation of transactions since the verification of the identity of the individual using the identification object is based on his biometric data.
- the data transmissions - Bio, K com , Id2 or their derived values - can be direct or pass through one or more intermediate devices, for example in the case where the transmission is through a communication network.
- the format of the transmitted data may be any.
- these transmissions are carried out in a secure manner.
- any appropriate procedure for securing the transmission can be envisaged, such as the use of HTTPS, SSL / TLS or other.
- a single server 30 may be used or several entities may perform respective functions; for example, an entity may be dedicated to computing or storing data from the biometric values used, and another entity may be dedicated to storing and comparing the digital identity.
- one or more personal data of the individual can be transmitted to the server 30 in the same configurations as for the first identity Id1.
- This personal data may include any data that may be used in connection with authentication or identification. As an illustration, they may include at least one of: a password, an email address of the identification object, an identity, or other.
- the various data relating to the individual are stored in association by or for the server 30.
- each data associated with a digital identity can be used for separate functions or services (local or remote).
