[1. Overview of authentication method]
First, with reference to FIG. 1, an outline of a method for registering an authenticator to an authentication server according to an embodiment will be described. FIG. 1 is an explanatory diagram showing an overview of a method of registering an authenticator to an authentication server according to an embodiment. Note that FIG. 1 illustrates an example in which a FIDO authenticator is registered with an authentication server that has both a FIDO (Fast Identity Online) authentication function for accessing an external server and a password authentication function.

As shown in FIG. 1, the information processing system 1 includes a terminal device 10 and an authentication server 100. As shown in FIG. The terminal device 10 and the authentication server 100 are connected to communicate with each other by wire or wirelessly via a network N (see FIG. 2). In this embodiment, the terminal device 10 cooperates with the authentication server 100 .

The terminal device 10 is a client device used by a user U (user). For example, the terminal device 10 is a smart device such as a smartphone or a tablet, and is a mobile terminal device capable of communicating with any server device via a wireless communication network such as 4G (Generation) or LTE (Long Term Evolution). is. The terminal device 10 has a screen such as a liquid crystal display and has a touch panel function. Accepts various operations for . An operation performed on an area where content is displayed on the screen may be an operation on the content. In addition, the terminal device 10 may be an information processing device such as a desktop PC (Personal Computer) or a notebook PC as well as a smart device.

The terminal device 10 according to the present embodiment can function as a FIDO authentication server instead of the authentication server 100 by installing a FIDO-enabled Password Manager, for example. Note that the FIDO-compatible password manager is an example and is not essential. In FIDO authentication, the identity of the user U is verified by an authenticator (Authenticator) built in or externally attached to a client device such as a smart phone. In this embodiment, the identity of the user U is verified by a FIDO authenticator built in or externally attached to the terminal device 10 of the user U. FIG.

That is, the terminal device 10 of the user U has a FIDO authenticator built in or externally attached to the terminal device 10, and verifies the user U's identity. For example, the FIDO authenticator may be a biometric authentication function of a smartphone, or may be an external authenticator such as a USB (Universal Serial Bus) key. Also, the FIDO authenticator may be an internal authenticator implemented inside the terminal device 10 of the user U in a form including software such as an application or a browser, or a specific hardware area. Further, the FIDO authenticator may be an authenticator capable of communicating with the terminal device 10 of the user U by wired communication or short-range wireless communication, and may be physically different from the terminal device 10 . In this embodiment, a case in which the terminal device 10 has an internal FIDO authenticator will be described as an example.

Some existing password managers apply FIDO authentication using a screen lock as an authentication means for starting to use the password manager. However, this is local authentication (screen unlocking) in the terminal device, and does not perform FIDO authentication for using other websites. However, the terminal device 10 according to the present embodiment can realize an authentication method in which the FIDO authentication function for accessing the external server and the password authentication function coexist by implementing, for example, a FIDO-compatible password manager. . Note that FIDO is only an example. Actually, not limited to FIDO, it is a type of authentication method that notifies a remote server of information on the verification result of user verification performed locally and authenticates the user by verifying the information on the verification result on the server. good too.

The authentication server 100 is an information processing device that functions as an authentication server having both FIDO authentication function and password authentication function, and is realized by a server device, a cloud system, or the like. That is, the authentication server 100 has both the FIDO authentication function and the password authentication function. For example, an authentication server of a company or the like that provides a wide variety of large-scale services may already support both the FIDO authentication function and the password authentication function.

For example, the authentication server 100 activates FIDO authentication through an existing password UI (user interface) screen of the terminal device 10 and receives authentication result information from the terminal device 10 . Thereby, the authentication server 100 introduces the FIDO authentication function into the terminal device 10 without modifying the existing interface of the terminal device 10 such as password authentication.

In this embodiment, in the case where the authentication server 100 already has both the FIDO authentication function and the password authentication function, the terminal device 10 allows the user U to lock the screen of the device (unlock). When the biometric information is registered (or input), it cooperates with the authentication server 100 to guide the process of registering the FIDO authenticator for a predetermined service. Alternatively, it automatically implements the registration of the FIDO authenticator. At this time, the terminal device 10 performs authentication using biometric information only inside the terminal and does not send the biometric information to the authentication server 100 .

The biometric information may be fingerprints, veins, faces, irises, voiceprints, or any combination thereof. In this embodiment, fingerprint data is used as an example of biometric information. In the present embodiment, the terminal device 10 uses the FIDO authenticator to confirm the identity of the user through biometric authentication based on biometric information. Means are not limited to biometric authentication. For example, the terminal device 10 may verify the identity of the user U by authentication using a token that generates a one-time password using a FIDO authenticator.

In addition, the authentication server 100 cooperates with the terminal device 10 of each user U, and provides the terminal device 10 of each user U with API (Application Programming Interface) services for various applications and various data. may At this time, the authentication server 100 may cooperate with the terminal device 10 of each user U to provide the terminal device 10 with a function as a FIDO-compatible password manager.

Also, the authentication server 100 may be an information processing device that provides some kind of web service online to the terminal device 10 of each user U. FIG. For example, the authentication server 100 serves as Web services such as Internet connection, search service, SNS (Social Networking Service), electronic commerce, electronic payment, online game, online banking, online trading, accommodation/ticket reservation, video/music distribution, etc. may provide services. In practice, the authentication server 100 may cooperate with various servers that provide web services as described above, mediate web services, or take charge of web service processing.

Also, the authentication server 100 can acquire user information about the user U. FIG. For example, the authentication server 100 acquires information about attributes of the user U, such as the user U's sex, age, and area of residence. The authentication server 100 stores and manages identification information indicating the user U (user ID, etc.) and information about the attributes of the user U. FIG.

Further, the authentication server 100 acquires various types of history information (log data) indicating actions of the user U from the terminal device 10 of the user U or from various servers based on the user ID or the like. For example, the authentication server 100 acquires a location history, which is a history of the user U's location and date and time, from the terminal device 10 . The authentication server 100 also acquires a search history, which is a history of search queries input by the user U, from a search server (search engine). Further, the authentication server 100 acquires a viewing history, which is a history of content viewed by the user U, from the content server. The authentication server 100 also acquires a purchase history (payment history), which is a history of user U's product purchases and payment processing, from an electronic commerce server or a payment processing server. Further, the authentication server 100 may acquire the exhibition history and the sales history, which are the history of the user U's exhibition in the marketplace, from the electronic commerce server or the settlement server. The authentication server 100 also acquires the posting history, which is the posting history of the user U, from a posting server that provides a word-of-mouth posting service or an SNS server.

[1-1. Authentication method]
Here, a method for registering an authenticator to an authentication server according to the embodiment will be described with reference to FIG.

For example, as shown in FIG. 1, the terminal device 10 activates the biometric information registration function, and when the user U registers the biometric information (fingerprint, etc.) for the screen lock function of the device, the biometric information is detected (step S1). At this time, the terminal device 10 registers the registered biometric information in the memory area 40A inside the terminal device 10 . Memory area 40A may be a secure area. A secure area is a memory area in which security is ensured.

For example, the terminal device 10 first introduces/connects the FIDO authenticator, and when the user U registers the biometric information for the screen lock function of the device, or when the user U registers the biometric information for unlocking the screen lock. When information is input, it is detected as an event that performs biometric information registration processing. At this time, the terminal device 10 may acquire biometric information registered for the screen lock function of the device or the like as detection of an event for biometric information registration processing. That is, the terminal device 10 may acquire already registered biometric information.

It should be noted that the terminal device 10 may detect an event in which biometric information registration processing is performed when the user U needs to re-register biometric information for some reason. In addition, the terminal device 10 is not limited to the screen lock function of the device, and when the user U registers the biometric information for a predetermined service that requires the user U to register the biometric information, the user U can register the biometric information. You may detect an event that handles

Subsequently, when the registration of the user U's biometric information is completed, the terminal device 10 activates the FIDO key registration function and performs authentication using an existing authentication method (such as a password) via the network N (see FIG. 2). After that, the user logs in to the authentication server 100 (step S2). That is, the authentication server 100 stores authentication information regarding existing authentication methods in advance. For example, the authentication server 100 stores authentication IDs (Identifiers) and passwords used in existing authentication methods.

The terminal device 10 prepares in advance a list of URLs (Uniform Resource Locators) of authentication servers as authentication server information about the authentication server 100 for each authentication server. The URL of the authentication server may be associated with an authentication ID and password used for logging into the authentication server. At this time, the terminal device 10 has previously registered the authentication server information in the memory area 40B inside the terminal device 10 . Memory area 40B may be a secure area. However, in practice, the terminal device 10 may use information stored in advance in a password manager or the like as the authentication server information.

Subsequently, the authentication server 100 requests the terminal device 10 to perform FIDO key registration processing via the network N (see FIG. 2) (step S3). At this time, the terminal device 10 receives a request for FIDO key registration processing from the authentication server 100 via the network N (see FIG. 2). Then, the terminal device 10 starts subsequent FIDO key registration processing in response to a request for FIDO key registration processing from the authentication server 100 .

In practice, the terminal device 10 may automatically start subsequent FIDO key registration processing after logging in to the authentication server 100 regardless of a request for the FIDO key registration processing from the authentication server 100 . That is, the request for FIDO key registration processing from the authentication server 100 is not essential.

Subsequently, the terminal device 10 generates a key pair of a private key and a public key (step S4). Note that when there are a plurality of authentication servers 100, the terminal device 10 generates a key pair of a private key and a public key for each authentication server. At this time, the terminal device 10 registers the generated key pair of the private key and the public key in the memory area 40C inside the terminal device 10 . Memory area 40C may be a secure area.

Subsequently, the terminal device 10 generates a registration certificate (attestation) of the FIDO authenticator (step S5). If there are a plurality of authentication servers 100, the terminal device 10 generates a registration certificate for each authentication server, similarly to the key pair. At this time, the terminal device 10 registers the generated registration certificate in the internal memory area 40</b>D of the terminal device 10 . Memory area 40D may be a secure area.

Here, the terminal device 10 may generate either the key pair of the private key and the public key or the registration certificate first. That is, the order of the processing in step S4 and the processing in step S5 may be reversed.

Subsequently, the terminal device 10 sends the public key and the registration certificate to the authentication server 100 via the network N (see FIG. 2) (step S6).

Subsequently, the authentication server 100 receives the public key and the registration certificate from the terminal device 10 via the network N (see FIG. 2), verifies the registration certificate, and verifies the validity of the registration certificate. If verified, the public key is registered (step S7).

Here, the terminal device 10 executes the above FIDO key registration processing for all authentication servers described in the authentication server information. That is, after the processing of step S1, the terminal device 10 performs the processing of steps S2 to S6 for all the authentication servers described in the authentication server information. At this time, the terminal device 10 may create a batch file for repeatedly performing the processes of steps S2 to S6 in the order of the authentication servers described in the authentication server information.

In the FIDO authentication process after the FIDO key registration, the terminal device 10 performs user verification based on the biometric information acquired from the user U by the FIDO authenticator. Then, when the identity of the user U can be verified, the terminal device 10 extracts the private key registered in the internal memory area, and signs (electronically) the challenge sent from the authentication server 100 with the private key. signature). After that, the terminal device 10 sends the signed challenge as a response to the authentication server 100 . The authentication server 100 verifies the signed challenge using the public key registered from the terminal device 10 . At this time, the authentication server 100 may verify the signature and the challenge.

Also, in the above explanation of the FIDO key registration process, the relationship between the terminal device 10 and the authentication server 100 is taken as an example. , and the relationship between the external authenticator and the terminal device 10, the same processing can be performed. At this time, the terminal device 10 uses the public key registered from the external authenticator to verify the signed challenge sent from the external authenticator that has performed user verification, and verifies the identity of user U and the external authenticator. can be verified, the ID and password registered in the internal memory area may be extracted and logged into the authentication server 100 using the extracted ID and password.
