Blockchain DID-based non-face-to-face market research panel qualification authentication system, panel terminal, and its control method {BLOCKCHAIN DID-BASED NON-FACE-TO-FACE MARKET RESEARCH PANEL QUALIFICATION SYSTEM, PANEL DEVICE AND CONTROL METHOD THEREOF}

The present invention relates to a market research panel qualification system, and more specifically, to a system that can perform qualification authentication for surveys for market research, etc. based on blockchain DID (Decentralized Identity)-based credentials, and its control method. It's about.

In general, various methods of conducting surveys are proposed through wired media such as the Internet.

Most of these methods do not allow the survey panel to actively participate in the survey, but usually only interested subjects participate. Therefore, there is a problem that it takes a considerable period of time to secure a certain number of response samples.

In addition, since the survey panel is not an active participant and is mainly met while surfing the web, there is a high possibility that the responses to the survey will not be faithful, and as a result, there is a problem that the reliability of the survey responses is low.

Since the subjects responding to the survey are not determined, the characteristics of the respondents cannot be identified, and even if the survey results are analyzed accordingly, there are bound to be limitations in the analysis pattern.

Therefore, there is a need for research on panel qualification technology that certifies the qualifications of the survey panel and specifies a survey panel that accurately matches the type of survey based on the proven qualifications.

DID (Decentered Identity) refers to a decentralized identity verification service that uses blockchain technology to prove an individual's identity through a distributed ledger that cannot be forged or altered and allows the individual to manage their personal information.

Terms used to describe DID-related technologies are defined as follows.

* Definition of DID-related terms

- User (holder) refers to a subject who wishes to prove his or her identity. Users can prove their identity by receiving identity information from the issuing agency and submitting it to the user agency (verification agency).

- Issuer refers to an entity that issues or issues identity information when it receives a request for identity verification from a user seeking identity verification. Issuers can sign issued identity information with their own private key and record their public key on the blockchain server.

- User agency (service provider, verifier) refers to the entity that verifies the identity information submitted by the user. For example, after verifying the user's identity information that he or she is a graduate of "OO University," the user organization may be a company that uses this as a basis for hiring.

- The key value of DID is information indicating the location of the DID Document.

- DID Document refers to information stored in the blockchain when issuing a DID. The DID Document includes key value, public key information related to the key value, authentication information to authenticate ownership of the key value, and information about services that can interact with the key value. It contains one or more of the following, and DID Documents are generally stored in blockchain.

- Verifiable Credential (VC) refers to a set of at least one user's personal information(s) issued by an Issuer, and VC is stored in a safe place such as a DID agent terminal (user-owned terminal). Saved. For example, it may include the user's resident registration number, gender, age, university attended, department attended, etc.

- VP (Verifiable Presentation) refers to a group (set) in which the user selects only the identity information he or she wishes to submit to the user agency among the identity information stored in the DID agent terminal. At this time, the selected identity information(s) can be signed with the user's private key, and the user agency can verify the identity information(s) with the user's public key recorded on the blockchain server.

The present invention proposes to provide a system that can encourage participation in market research surveys through highly reliable panel credentials and a reasonable compensation system.

In particular, the loss or theft of unwanted personal information can be minimized by managing the profile information of panels participating in the survey on each panel terminal in the form of DID-based identity information, rather than centrally managing it.

Hereinafter, it will be described in more detail with reference to the drawings.

Figure 1 is a diagram showing a conceptual diagram of a panel qualification certification system 100 according to an embodiment of the present invention.

The panel qualification certification system 100 according to the drawing includes at least one of a research agency server 101, a qualification server 102, a blockchain server 103, a panel terminal 104, and a client company terminal 105. It may be configured to include.

The components shown in FIG. 1 are not essential for implementing the panel certification system 100, so the panel certification system 100 described in this specification may have more or fewer components than those listed above. It can have elements.

Terminals described in this specification include mobile phones, smart phones, laptop computers, digital broadcasting terminals, personal digital assistants (PDAs), portable multimedia players (PMPs), navigation, slate PCs, Mobile terminals such as tablet PCs, ultrabooks, and wearable devices (e.g., smartwatches, smart glasses, and head mounted displays) It may include fixed terminals such as digital TVs, desktop computers, digital signage, etc.

The research agency server 101 refers to a server managed by a research agency that conducts market research, and is an entity that acts as a verifier to verify the DID and identity information (Verifiable Credential) of the panel terminal 104. . When a research agency has already secured a number of panel terminals 104, it can receive a request for market research from a client company. The research agency server 101 delivers the survey request for the requested market research to a plurality of panel terminals 104 that have already been secured.

When the panel terminal 104 requests the investigation agency server 101 to verify its own identity information, the investigation agency server 101 secures the panel terminal 104 by verifying the identity information of the panel terminal 104. You can.

The qualification server 102 not only issues DID and identity information to the panel terminal 104, but also performs panel qualification verification for the panel terminal 104 at the request of the investigation agency server 101. In other words, the qualification server 102 is a subject that acts as an issuer issuing DID and identity information.

The blockchain server 103 generates the DID of the panel terminal 104 and manages and verifies the DID Document.

The panel terminal 104 is a subject participating in a market research survey, and receives and stores DID and identity information from the qualification server 102. As will be explained in more detail below, whether to participate in the survey (whether to output a notification) for the corresponding panel terminal 104 is determined based on the identity information stored in the panel terminal 104. The panel terminal 104 is an entity that acts as a user (holder) utilizing DID and identity information.

The requesting company terminal 105 refers to a terminal used by a company that requests a market research from a research agency. The requesting company terminal 105 can access the qualification server 102 and monitor the progress of the market research process performed by the research agency.

Hereinafter, the detailed configuration of the panel terminal 104 and the client company terminal 105 according to an embodiment of the present invention will be described. The panel terminal 104 and the client company terminal 105 are collectively referred to as the terminal 200.

Figure 2 is a block diagram for explaining the terminal 200 related to the present invention.

The terminal 200 may include a wireless communication unit 110, an input unit 120, an output unit 150, a memory 170, a control unit 180, and a power supply unit 190. The components shown in FIG. 2 are not essential for implementing the terminal 200, so the terminal 200 described in this specification may have more or fewer components than the components listed above.

More specifically, among the above components, the wireless communication unit 110 is responsible for wireless communication between the terminal 200 and the wireless communication system, between the terminal 200 and another terminal 200, or between the terminal 200 and an external server. It may contain one or more modules that enable. Additionally, the wireless communication unit 110 may include one or more modules that connect the terminal 200 to one or more networks.

The input unit 120 includes a camera or video input unit for inputting video signals, a microphone or audio input unit for inputting audio signals, and a user input unit (e.g., touch key, push key) for receiving information from the user. (mechanical key), etc.) may be included. Voice data or image data collected by the input unit 120 may be analyzed and processed as a user's control command.

The output unit 150 is intended to generate output related to vision, hearing, or tactile senses, and may include at least one of a display unit 151 and an audio output unit 152. The display unit 151 can implement a touch screen by forming a layered structure or being integrated with the touch sensor. This touch screen functions as a user input unit 123 that provides an input interface between the terminal 200 and the user, and can simultaneously provide an output interface between the terminal 200 and the user.

Additionally, the memory 170 stores data supporting various functions of the terminal 200. The memory 170 may store a number of application programs (application programs or applications) running on the terminal 200, data for operating the terminal 200, and commands. At least some of these applications may be downloaded from an external server via wireless communication. Additionally, at least some of these applications may be present on the terminal 200 from the time of shipment for basic functions of the terminal 200 (e.g., call incoming and outgoing functions, message reception and sending functions). Meanwhile, the application program may be stored in the memory 170, installed on the terminal 200, and driven by the control unit 180 to perform the operation (or function) of the terminal 200.

Furthermore, the memory 170 according to an embodiment of the present invention is proposed to further include a secure storage 170' with enhanced security in addition to a general storage. In the case of the secure storage 170', the risk of personal information being leaked due to external hacking or loss of a mobile phone is minimized through encryption by the OS. The terminal 200 according to an embodiment of the present invention proposes to store the DID private key or identity information described below in the secure storage 170'.

In addition, the terminal 200 according to an embodiment of the present invention further includes a sensing unit (not shown) for biometric authentication, and allows access to the secure storage 170' only when biometric authentication is performed. do.

In addition to operations related to the application program, the control unit 180 typically controls the overall operation of the terminal 200. The control unit 180 can provide or process appropriate information or functions to the user by processing signals, data, information, etc. input or output through the components discussed above, or by running an application program stored in the memory 170.

Additionally, the control unit 180 may control at least some of the components examined with FIG. 2 in order to run an application program stored in the memory 170. Furthermore, the control unit 180 may operate at least two of the components included in the terminal 200 in combination with each other in order to run the application program.

The power supply unit 190 receives external power and internal power under the control of the control unit 180 and supplies power to each component included in the terminal 200. This power supply unit 190 includes a battery, and the battery may be a built-in battery or a replaceable battery.

At least some of the above components may cooperate with each other to implement the operation, control, or control method of the terminal 200 according to various embodiments described below. Additionally, the operation, control, or control method of the terminal 200 may be implemented on the terminal 200 by running at least one application program stored in the memory 170.

Below, with reference to FIG. 3, the process by which the panel terminal 104 receives DID and identity information will be described.

Figure 3 is a diagram illustrating a flowchart of the panel terminal 104 issuing DID and identity information according to an embodiment of the present invention.

The user of the panel terminal 104 will be able to install software (application) on his or her panel terminal 104 to use the service of the present invention and perform the procedures of the present invention through the software. The procedures performed through the panel terminal 104 can be performed through the installed software, and for convenience of explanation, the explanation that they are performed by software will be omitted below.

First, the panel terminal 104 may perform an identity authentication procedure for the user (S301). The identity authentication process can refer to a variety of procedures that allow the user to confirm whether or not it is the user. A representative example is a method of replacing the resident registration number (CI) through a credit card authentication process in the user's name or a mobile communication terminal authentication process. You can verify your identity or go through the mobile communication terminal authentication process.

When the identity authentication process is successfully completed, the panel terminal 104 may request the issuance of a DID from the qualification authentication server 102 (S302).

The qualification server 102 may issue a DID (S303) in response to the S302 request. When a DID is issued, there is a private key and a public key generated. The private key is sent back to the panel terminal 104 (S304-1), and the public key is delivered to the blockchain server 103 (S304-2).

The panel terminal 104 that received the private key reply stores it (S305-1), and the blockchain server 103 that received the public key reply creates a DID Document corresponding to the issued DID (S305-2) and DID Save the reply public key in the document. And the key value of the DID of the created DID Document is returned. The credentialing server 102 that receives the DID key value can match the DID key value with user information about the panel terminal 104 and store it.

Afterwards, the panel terminal 104 transmits a request for issuance of identity information to the qualification server 102 (S307).

The qualification server 102 may issue identity information in response to a request from the panel terminal 104. At this time, the issued identity information may be encrypted (signed) with the private key of the qualification server 102. And the public key corresponding to the private key of the credential authentication server 102 is also stored in the blockchain server 103 and provided for anyone to check.

The qualification server 102 returns identity information encrypted with its own private key to the panel terminal 104 (S309). The panel terminal 104 may store the received identity information in the memory 170 (S310). In this way, the location where the identity information is stored is stored in the personal storage of the panel terminal 104, not in a public storage. Furthermore, the panel terminal 104 according to an embodiment of the present invention proposes to store the identity information in the secure storage 170' of the memory 170. This is because identity information has a high level of personal information.

Meanwhile, it is proposed that identity information according to an embodiment of the present invention be created in stages. This step-by-step identity information will be described with reference to FIG. 4. If identity information is provided in stages, the user of the panel terminal 104 will be able to selectively select identity information according to his or her needs.

Figure 4 shows an example of step-by-step identity information according to an embodiment of the present invention.

The system according to the present invention enables provision of selective information through a customized survey based on step-by-step identity information. Types of identity information according to an embodiment of the present invention include first identity information containing only basic first-stage information, second identity information further containing second-stage information more in-depth than the first-stage information, and specific industrial group. It may include third party identity information including usage pattern information.

In blockchain DID, it can be managed by dividing it into levels so that it can be distinguished according to the necessary information required for identity information at each stage, as shown below.

- [VC-G1] Check basic profile (name, gender, age, email, region of residence)

- [VC-G2] Check additional profiles (vehicle and home ownership, income, household composition, etc.)

- [VC-G3] Confirm qualification identity information according to the industry-specific nature of the survey (profile information according to the survey field (vehicle registration, public proof such as family relationship registration, etc.))

For example, in the case of [VC-G1] grade, only basic demographic information corresponding to the first stage information may be included. And the [VC-G2] grade may further include second-level information in addition to the first-level information. The second level information is additional identity information and may additionally include occupation and work environment information. [VC-G3] Grade adds information according to the industry-specific nature of the survey, and in order to input information from the first to third stages, the user of the panel terminal 104 must complete appropriate documentation.

Compensation in the system according to an embodiment of the present invention may be provided differentially according to the level of identity information. For example, the compensation for a market research survey that only requires [VC-G1] grade may be higher for a market research survey that requires [VC-G3] grade.

In other words, since surveys that require the characteristics of the automobile industry target only drivers, they can only be provided to panels that meet the [VC-G3] grade required for a driver's license or vehicle registration, and compensation for these surveys is general. It may be set higher than the survey reward.

Meanwhile, in one embodiment of the present invention, it is proposed to filter requests for survey participation based on the identity information stored in each of the panel terminals 104. Such an embodiment will be described with reference to FIG. 5 .

Figure 5 is a diagram illustrating an example of filtering requests for survey participation according to an embodiment of the present invention.

The research agency server 101 transmits a survey participation request (S501) to the panel terminal 104. At this time, the survey participation request may be transmitted in batches to a plurality of panel terminals 104 secured by the research agency server 101.

The panel terminal 104 can check the participation conditions included in the survey participation request (S502). At this time, the participation conditions may include specific items such as the panel's gender as male/female, but may also include whether or not the grade of the identity information is met. For example, when the [VC-G3] grade is set as a participation condition, the panel terminal 104 that stores only the identity information of the [VC-G1] and [VC-G2] grades may not satisfy the participation condition.

In step S503, the panel terminal 104 checks whether the confirmed participation conditions are satisfied. If you do not meet the participation conditions, you can quit immediately without printing a notification. If the participation conditions are met, the process proceeds to step S504 and a notification can be output to the user.

Notifications provided to users may take various forms. For example, it may be provided to the user in the form of a push notification, and the notification may also be made in the form of a pop-up output and vibration/sound output on the display unit 151.

That is, according to the above-described steps, a notification regarding the survey participation request (S501) can be selectively output based on the identity information stored in the panel terminal 104. For example, in the case of a survey request set only for men, a notification may not even be displayed to female panelists. This may have the effect of filtering the survey participation request itself.

Filtering of survey participation requests is practically impossible due to legal issues. This is because the research agency cannot store personal information about the panelists. Therefore, the reality is that Joshigwan has no choice but to randomly send participation in surveys that do not suit them to all panel members. However, in the embodiment of the present invention, when using the identity information stored in the panel terminal 104, requests for survey participation can be substantially filtered, so the survey can be notified/exposed only to appropriate panels. This exists.

In step S505, the panel terminal 104 may receive an input from the user regarding whether or not to accept the request to participate in the survey. If the user does not accept, the step can end immediately. If the user of the panel terminal 104 accepts, the process proceeds to step S506 and a VP (Verifiable Presentation) can be created.

The user of the panel terminal 104 can select only the identity information he or she wishes to prove among a plurality of pieces of identity information (or step-by-step identity information). This is to minimize exposure of unnecessary personal information by collecting and submitting only the identity information needed at that time.

The identity information selected in this way is signed (encrypted) with the private key of the user of the panel terminal 104 and is called VP.

The panel terminal 104 transmits the VP along with acceptance of participation to the research agency server 101 (S507). The submitted VP may be provided along with the DID key value of the user of the panel terminal 104.

The research agency server 101 requests a public key from the blockchain server 103 based on the DID key value of the panel terminal 104 user (S508). At this time, the requested public key may include the public key of the user of the panel terminal 104 as well as the public key of the credential authentication server 102.

The blockchain server 103 searches the DID Document based on the DID key value included in the public key request, and the public key of the user of the panel terminal 104 and the public key of the authentication server 102 included in the DID Document. You can reply (S509).

The investigation agency server 101 can verify the identity information (S510) using the public key received in response. In other words, the panel terminal 104 examines whether it is qualified to participate in the survey.

If the panel terminal 104 determines that it can participate in the survey, the panel terminal 104 and the research agency server 101 perform an agreement (contract) for the survey (S511). The implementation of the agreement may be an agreement in which the research agency server 101 provides compensation on the condition that the panel terminal 104 participates in the survey.

In the embodiment related to FIG. 5, a request for survey participation was made through a notification output to the panel terminal 104. However, it is not limited to this form, and an embodiment in which the panel terminal 104 checks the status of various surveys currently in progress and selects a desired survey may also be possible. This embodiment will be described with reference to the flow chart of FIG. 6 and the screen state diagram of FIG. 7.

Figure 6 is a diagram illustrating a flowchart of the survey participation procedure of the panel terminal 104 through survey status inquiry according to an embodiment of the present invention. Figure 7 is a diagram showing a screen state diagram for inquiry status according to an embodiment of the present invention.

The panel terminal 104 may request the survey status of surveys currently in progress from the research agency server 101 (S601). In response to the survey status request, the research agency server 101 may check the survey status (S602) and reply with the confirmed result (S603).

The panel terminal 104 can output the survey status to the user through the display unit 151 based on the returned survey status (S604). The output of the survey status according to one embodiment of the present invention may be filtered based on the identity information registered in the panel terminal 104.

Referring to FIG. 7, a list of survey items output through the panel terminal 104 is displayed. For each survey item, specific information about participation conditions, compensation, etc. may be output.

If there is a survey item in which the user of the panel terminal 104 wishes to participate, the user of the panel terminal 104 will be able to accept participation in the survey through the selection input 10a of the survey item.

In one embodiment of the present invention, it is proposed to check the identity information of the panel terminal 104 and filter and output survey items that do not meet the survey participation conditions. For example, survey items that do not meet the participation conditions may be output as 'blurred'. If an input 10b for selecting a corresponding survey item is received, a text informing participation conditions such as “To perform the survey, OOO conditions are required” may be output.

If the identity information is updated to satisfy the conditions, the panel terminal 104 will be able to participate in the corresponding survey items.

Hereinafter, the user acceptance (S505) to agreement (S511) steps are the same as those described above in FIG. 5, so detailed descriptions are omitted.

Above, an embodiment of the market research panel qualification system according to the present invention and a panel terminal using the same has been described, but this is explained as at least one embodiment, and the technical idea, structure, and operation of the present invention are not limited thereby. This means that the scope of the technical idea of the present invention is not limited/limited by the drawings or the description referring to the drawings.
