Conventionally, there has been known a mechanism for providing information suitable for the user in response to the operation of the web browser by the user. For example, Patent Document 1 describes an information distribution system for performing effective behavioral targeting advertisement. When the user terminal displays a website, this information distribution system associates the cookie ID assigned to the cookie of the user terminal with the terminal ID and collects the browsing history of the user terminal on the website. In addition, the information distribution system collects the action history of the user terminal. Then, the information distribution system determines the user attribute based on the browsing history and the action history, and displays the information corresponding to the user attribute on the user terminal or the video display device.

JP-A-2019-67311

In order to provide information suitable for the user, it is necessary to recognize the user, and user authentication is performed for the recognition. However, if user authentication is executed every time information is provided, the convenience of the computer system is reduced. Therefore, a mechanism for providing information suitable for the user without executing user authentication is desired.

The information providing system according to one aspect of the present disclosure includes an account identifier for identifying a user and a terminal for identifying the user terminal in response to the web browser of the user terminal accessing the first web page. Cookie information is generated by associating the identifier and the tracking ID corresponding to the first web page with the cookie ID for identifying the cookie corresponding to the web browser, and the cookie information is stored in the user terminal. In response to the cookie processing unit and the web browser accessing the second web page, the cookie information is acquired from the user terminal, and the user profile of the user is acquired by referring to the user database using the cookie information. A content providing unit that transmits content data based on the user profile to the user terminal is provided.

In such an aspect, in response to the access from the user terminal to the first web page, the cookie information in which the account identifier, the terminal identifier, and the tracking ID are associated with the cookie ID is stored in the user terminal. When the user terminal subsequently accesses the second web page, content data based on the user profile corresponding to the cookie information is generated, and the content data is transmitted to the user terminal. By using the above-mentioned cookie information already stored in the user terminal, it is possible to provide information suitable for the user without executing user authentication.

According to one aspect of the present disclosure, it is possible to provide information suitable for the user without executing user authentication.

Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same or equivalent elements are designated by the same reference numerals, and duplicate description will be omitted.

The information providing system 1 according to the embodiment is a computer system that provides information suitable for the user in response to the user accessing a specific web page. When the user operates the web browser of the user terminal to access the web page, the information providing system 1 responds to the access, generates content data suitable for the user, and transmits the content data to the user terminal. .. The user terminal displays the content data, whereby the user can confirm the provided information. Content is information provided by a computer or computer system that is human recognizable. Content data is electronic data that indicates the content.

FIG. 1 is a diagram showing an example of the configuration of the information providing system 1. In one example, the information providing system 1 includes a user terminal 10, an account management system 20, an identifier management system 30, and a service system 40. These computers or computer systems can send and receive data to and from each other over a communication network. The configuration of the communication network is not limited and may be designed according to any policy. For example, a communication network may be constructed including various network configurations such as a mobile communication network, the Internet, an intranet, and a WAN (Wide Area Network). Although only one user terminal 10 is shown in FIG. 1, the number of user terminals 10 related to the information providing system 1 is not limited at all, and the information providing system 1 processes related to the provision of content data for each of the plurality of user terminals 10. May be executed.

The user terminal 10 is a computer operated by the user. The type of user terminal 10 is not limited. For example, the user terminal 10 may be a mobile phone, a high-performance mobile phone (smartphone), a tablet terminal, a wearable terminal (for example, a smart watch, a head-mounted display (HMD), etc.), or a mobile terminal such as a laptop. Alternatively, the user terminal 10 may be a stationary personal computer. The user terminal 10 includes a web browser 11 which is software for browsing a web page provided on the Internet. The user terminal 10 includes a cookie processing unit 12 and a content processing unit 13 as functional elements. The cookie processing unit 12 is a functional element that executes processing related to cookie information used for acquiring content data. In one example, the cookie processing unit 12 may be realized by a group of programs embedded in one or more web pages, and may be realized by, for example, a group of programs described by Javascript (registered trademark). The cookie information is stored in the storage 1003 described later. The content processing unit 13 is a functional element that executes processing related to content data.

The account management system 20 is a computer system that manages the accounts of individual users. An account is the right to log in to services provided on the Internet. Each account is uniquely identified by an account identifier. More specifically, the account identifier in the present disclosure means an identifier that uniquely identifies the combination of the user and the contract for using the service. The account management system 20 includes an account management unit 21, an authentication infrastructure 22, and an account database 23 as functional elements. The account management unit 21 is a functional element that processes account information related to the accounts of individual users. The authentication platform 22 is a functional element that executes processing related to user authentication. The account database 23 is a device (storage unit) for storing account information.

The identifier management system 30 is a computer system that manages the correspondence between the account identifier and the cookie ID for each user. A cookie is a piece of information used to manage the state between a web browser and a server. Therefore, cookies are compatible with web browsers. The formal term is HTTP (HyperText Transfer Protocol) cookies, but in this disclosure it is simply referred to as "cookies". The cookie ID is an identifier that uniquely identifies the cookie. The identifier management system 30 includes an identifier management unit 31 and an identifier database 32 as functional elements. The identifier management unit 31 is a functional element that manages identifier information indicating the correspondence between the account identifier and the cookie ID. The identifier database 32 is a device (storage unit) that stores the identifier information.

The service system 40 is a computer system that provides content data suitable for the user. The service system 40 includes a content providing unit 41 and a user database 42 as functional elements. The content providing unit 41 is a functional element that provides content data in response to a request from the user terminal 10. The user database 42 is a database that stores user profiles that are information about individual users.

Each of the account management system 20, the identifier management system 30, and the service system 40 is configured using at least one computer. In each computer system, the method of arranging individual functional elements is not limited, and it may be designed by an arbitrary policy.

FIG. 2 is a diagram showing an example of a data structure of information used in the information providing system 1, and more specifically, shows main data items for each information. The cookie information stored in the user terminal 10 corresponds to the account information in the account database 23, the identifier information in the identifier database 32, and the user profile in the user database 42.

Each record of account information contains an account identifier and an account group number. The account group number is an identifier given to bundle one or more account identifiers of one user, and therefore one account group number is assigned to one user. Since the account identifier uniquely identifies the combination of the user and the service usage contract, when one user subscribes to a plurality of services, the user has a plurality of account identifiers. By preparing the account group number, it is possible to reliably identify one user who has multiple contracts.

Each record of identifier information includes a cookie ID, an account identifier, a hashed account identifier, and an account group number. The hashed account identifier is a character string obtained by hashing the account identifier of the account information. In the present disclosure, the account identifier before being hashed is also referred to as the "original account identifier", which, if necessary, makes the distinction from the "hashed account identifier" clearer.

The cookie information stored in the user terminal 10 includes a cookie ID, a hashed account identifier, a terminal identifier, and a tracking ID. The terminal identifier is an identifier that uniquely identifies the user terminal 10. The tracking ID is an identifier used to track the user's operation within the target website. For example, the tracking ID is embedded in each of any one or more web pages that make up the target website.

Each record in the user profile contains a hashed account identifier, an account group number, and a user attribute. A user attribute is information that indicates a property, feature, or state associated with a user. Examples of user attribute data items include, but are not limited to, name, address, telephone number, email address, date of birth, gender, and occupation. At least a part of the user profile may be composed of given member information or contractor information, and for example, the contractor information of mobile communication may be used as at least a part of the user profile.

The data structure of individual information stored in individual databases is not limited and may be designed according to any policy. For example, at least one of account information, identifier information, and user profile may be normalized or denormalized by any policy and stored on one or more data tables. An account group number for bundling one or more account identifiers for a user may not be used.

An example of processing executed by the information providing system 1 will be described with reference to FIGS. 3 and 4. FIG. 3 is a sequence diagram showing a processing procedure for storing the cookie information in the user terminal 10 as a processing flow S1. FIG. 4 is a sequence diagram showing a processing procedure for providing the content data to the user terminal 10 as a processing flow S2. The processing flow S1 is executed when the user terminal 10 has not yet stored the cookie information (for example, when the user terminal 10 accesses the target website for the first time). On the other hand, the processing flow S2 is executed after the user terminal 10 stores the cookie information (for example, when the user terminal 10 accesses the target website again). That is, the processing flow S2 is executed after the processing flow S1.

First, the processing flow S1 will be described. In step S101, the web browser 11 of the user terminal 10 accesses the first web page based on the user operation and displays the first web page. A series of processes for storing the cookie information in the user terminal 10 is executed in response to this access. Therefore, the first web page is a web page that is displayed before the cookie information is stored in the user terminal 10. In one example, the first web page includes a tracking ID corresponding to the target website and a program for executing at least a part of the functions of the cookie processing unit 12 (for example, a program described by Javascript (registered trademark)). including.

In step S102, the cookie processing unit 12 of the user terminal 10 acquires the terminal identifier and the tracking ID. The cookie processing unit 12 reads the terminal identifier stored in the storage 1003 in the user terminal 10 and acquires the tracking ID embedded in the first web page.

In step S103, the cookie processing unit 12 transmits a data signal for requesting the cookie ID to the identifier management system 30.

In step S104, the identifier management unit 31 of the identifier management system 30 generates a new cookie ID in response to the request, and transmits the cookie ID to the user terminal 10.

In step S105, the cookie processing unit 12 transmits a data signal for requesting authentication to the account management system 20.

In step S106, the account management unit 21 of the account management system 20 executes the authentication process in response to the request, and transmits the account identifier to the user terminal 10. The account management unit 21 inquires the authentication base 22 about the legitimacy of the user, and when the user is authenticated, acquires the account identifier of the user from the authentication base 22. The authentication platform 22 responds to an inquiry from the account management unit 21 and confirms the legitimacy of the user who intends to use the service. In one example, the authentication infrastructure 22 is whether or not the user has already been authenticated by a method such as single sign-on or line authentication (that is, whether or not the user can be regarded as already logged in to the service). To judge. When the legitimacy of the user can be confirmed, the authentication platform 22 reads the account identifier of the user from the account database 23 and provides the account identifier to the account management unit 21. The account management unit 21 transmits the account identifier to the user terminal 10. If the legitimacy of the user cannot be confirmed, the authentication infrastructure 22 may request the user terminal 10 to perform a predetermined authentication procedure via the account management unit 21.

In step S107, the cookie processing unit 12 transmits a data signal requesting identifier management to the identifier management system 30. In one example, the cookie processing unit 12 generates a data signal including the already acquired cookie ID and account identifier, and transmits this data signal to the identifier management system 30.

In step S108, the identifier management unit 31 of the identifier management system 30 transmits a data signal for requesting the account group number to the account management system 20. This data signal contains the account identifier.

In step S109, the authentication infrastructure 22 of the account management system 20 reads the account group number corresponding to the account identifier from the account database 23, and transmits the account group number to the identifier management system 30.

In step S110, the identifier management unit 31 hashes the account identifier. That is, the identifier management unit 31 generates a hashed account identifier. Hashing is a process of obtaining a hash value, which is a non-regular fixed-length value, from the original data according to a given calculation procedure, and replacing the original data with the hash value. Since this hashing is an irreversible transformation, the original data cannot be restored from the hash value. Therefore, hashing is a technique different from encryption that can restore the original data. By hashing the account identifier, the security of the account identifier used across a plurality of computers or computer systems in the information providing system 1 is enhanced, so that the personal information of the user can be protected more reliably.

In step S111, the identifier management unit 31 generates and stores the identifier information. The identifier management unit 31 generates a record of identifier information by associating a cookie ID, an account identifier (that is, the original account identifier), an account group number, and a hashed account identifier with each other. Then, the identifier management unit 31 stores the record in the identifier database 32.

In step S112, the identifier management unit 31 transmits the hashed account identifier to the user terminal 10.

In step S113, the cookie processing unit 12 generates and stores cookie information. The cookie processing unit 12 generates cookie information by associating the hashed account identifier, the terminal identifier, and the tracking ID with the cookie ID. Therefore, the cookie information does not include the original account identifier. The cookie processing unit 12 stores the cookie information in the storage 1003.

In step S114, the identifier management system 30 transmits the identifier information to the service system 40. In one example, this transmission may be achieved by batch processing rather than being performed in real time. In one example, each record in the user profile contains the account group number from the beginning. The service system 40 sets the hashed account identifier in the corresponding record of the user profile by reflecting the acquired identifier information in the user profile in the user database 42. As a result, the process of extracting the user profile corresponding to the hashed account identifier becomes possible.

When the cookie processing unit 12 stores the cookie information in the user terminal 10 in response to the web browser 11 accessing the first web page, the content providing unit 41 of the service system 40 does not generate the content data. The content data is generated when the processing flow S2 is executed after the processing flow S1 and is provided to the user terminal 10.

Next, the processing flow S2 will be described. In step S201, the web browser 11 of the user terminal 10 accesses the second web page based on the user operation and displays the second web page. A series of processes for providing the content data to the user terminal 10 is executed in response to this access. The second web page is a web page that is displayed after the first web page, and more specifically, it is displayed after the cookie information is stored in the user terminal 10 in response to the access to the first web page. It is a web page to be done. In one example, the second web page is related to the first web page, for example, the first web page and the second web page belong to the same website (ie, this website refers to the first web page and the second web page. include). In this case, the second web page includes a tracking ID corresponding to the target website and a program for executing at least a part of the functions of the cookie processing unit 12 (for example, a program described by Javascript (registered trademark)). including. Therefore, the tracking ID of the second web page is the same as the tracking ID of the first web page.

In step S202, the cookie processing unit 12 of the user terminal 10 acquires the tracking ID embedded in the second web page, and reads the cookie information including the tracking ID from the storage 1003.

In step S203, the cookie processing unit 12 transmits a data signal for requesting the content data to the service system 40. In one example, the cookie processing unit 12 generates a data signal including cookie information and transmits this data signal to the service system 40.

In step S204, the content providing unit 41 of the service system 40 acquires the user profile corresponding to the cookie information. In one example, the content provider 41 reads the user profile corresponding to the hashed account identifier from the user database 42. In steps S202 and S203, the cookie processing unit 12 reads the cookie information from the storage 1003 and transmits the cookie information without requesting user authentication. This means getting and sending cookie information without asking the user to log in to the service. In response to such processing on the user terminal 10, the content providing unit 41 acquires cookie information from the user terminal 10 without requesting user authentication.

In step S205, the content providing unit 41 generates content data based on the received cookie information and the read user profile. For example, the content providing unit 41 may specify the content to be generated based on the cookie ID, the terminal identifier, and the tracking ID, and determine the value to be included in the content based on the user profile. The structure and format of the content data are not limited in any way, and the content providing unit 41 may generate the content data according to an arbitrary policy. For example, the format of the content data may be an e-mail, a web page, or a social networking service (SNS) message. The information transmitted by the content data is also not limited. In one example, the content data includes information related to the target website to which the first web page and the second web page belong. For example, the content data may include advertising or promotional information related to the Target Website. Alternatively, the content data may include information for the user to reconsider withdrawal from the service related to the target website. In any case, since the user profile is used, it is possible to generate content suitable for each user attribute.

In step S206, the content providing unit 41 transmits the content data to the user terminal.

In step S207, the content processing unit 13 of the user terminal 10 displays the content data on the display device. The content processing unit 13 may automatically display the content data without waiting for the user operation, or may display the content data in response to the predetermined user operation. In any case, the user can check the content generated in response to accessing the second web page.

In the above embodiment, the account identifier is hashed, but this hashing is not an essential process. Therefore, the cookie information may include the original unhashed account identifier instead of the hashed account identifier. Each record of identifier information may include a cookie ID, an account identifier, and an account group number without including the hashed account identifier. Each record in the user profile may contain the original unhashed account identifier instead of the hashed account identifier.

In the above embodiment, the information providing system 1 includes a user terminal 10, an account management system 20, an identifier management system 30, and a service system 40, but the configuration of the information providing system is not limited to this. The division of roles between the computers and computer systems that make up the information provision system may be designed according to any policy.

The block diagram used in the description of the above embodiment shows a block of functional units. These functional blocks (components) are realized by any combination of at least one of hardware and software. Further, the method of realizing each functional block is not particularly limited. That is, each functional block may be realized by using one device that is physically or logically connected, or directly or indirectly (for example, by two or more devices that are physically or logically separated). , Wired, wireless, etc.) and may be realized using these plurality of devices.
