15 is a flowchart of an access authentication procedure between a user device and an affiliate member management server using an account of a block chain service according to an embodiment of the present invention.

Referring to FIG. 15 , in step S1000, the user device SS1 may generate block chain account information (eg, ID) through the user's block chain service membership subscription according to a predefined procedure. Unless contradictory, the block chain service membership registration is performed by the operation method of the node device for personal information operation based on the block chain of FIG. 3, and the user's personal information is stored and managed in the block of the block chain can Thereafter, in step S1005, the user device SS1 may transmit a login request message to the affiliate member management server SP1 using the block chain account information. The user may request access authentication from the affiliate member management server SP1 using the block chain account information without registering for a service provided by the affiliate member management server SP1. In step S1010, the affiliate member management server (SP1) responds to the authentication request of the user device (SS1) with a blockchain login interface call to the blockchain platform server (BCS), along with a unique blockchain of the affiliate member management server (SP1) The key and node ID can be transmitted. The unique block chain key and node ID may be encrypted for security enhancement and provided from the affiliate member management server SP1 to the block chain platform server BCS. The node ID may be an affiliate site ID of FIG. 9 or 11D.

Then, in step S1020, the block chain platform server (BCS) may transmit the block chain login interface to the user device (SS1) in response to the block chain login interface call. For example, the blockchain login interface of FIG. 8A may be provided from the blockchain platform server (BCS) to the user device (SS1). In step S1030, the user device SS1 may transmit a message requesting block chain account information (eg, ID) and a one-time password to the block chain platform server (BCS) as shown in FIG. 8B . In step S1040, the block chain platform server (BCS) responds to the request for the one-time password of the user device (SS1) and sends the one-time password corresponding to the block chain account information through the user's pre-registered email or mobile phone to the user device (SS1) ) can be sent to In step S1050, the user device (SS1) transmits a message requesting access authentication of the affiliate member management server (SP1) to the block chain platform server (BCS) using the one-time password received from the block chain platform server (BCS). can

Then, in step S1060, the block chain platform server (BCS) performs user authentication by comparing the one-time password transmitted to the user device (SS1) with the one-time password received from the user device (SS1), and the user's block chain account Using the information and the node ID received from the affiliate member management server SP1, it may be determined whether the user's personal information viewing right is provided to the affiliate member management server SP1.

By the user's selection, the user device (SS1) may transmit the user's personal information viewing right key to the affiliate member management server (SP1) through the block chain platform server (BCS), and the user's personal information viewing The affiliate member management server SP1 that has received the authorization key may read the user's personal information through the user's personal information viewing authorization key unless the user's personal information viewing authorization key is retrieved. Specifically, in step S1060, the block chain platform server (BCS) uses the user's block chain account information and the node ID received from the affiliate member management server (SP1), and the user ) to determine whether the personal information access right key has been provided.

In one embodiment, depending on whether the user has previously provided the personal information viewing authorization key to the affiliate member management server SP1, the user may be restricted from accessing the service of the affiliate member management server SP1. For example, when the user provides a personal information viewing authorization key to the affiliate member management server (SP1), more services of the affiliate member management server (SP1) can be accessed, and in the opposite case, the affiliate member management server (SP1) is limited can access the services of Also, step S1060 may be selectively performed by the user's login selection. For example, when the user requests a simple authentication procedure in step S1000, step S1060 may be omitted.

Thereafter, in step S1070, the block chain platform server (BCS) may encrypt the member identification key using the node ID and block chain key received from the affiliate member management server SP1. The member identification key is an identifier for the user device SS1 that has made a login request to the affiliate member management server SP1 in step S1005, and the member identification key may be a block chain account ID or a user's wallet unique key. The present invention is not limited thereto, and the member identification key may be an identifier predetermined by a procedure between the affiliate member management server SP1 and the user device SS1. Thereafter, in step S1080, the block chain platform server (BCS) may transmit the encrypted member identification key to the affiliate member management server SP1 in order to inform that the user authentication is complete.

Thereafter, in step S1090, the affiliate member management server SP1 decrypts the encrypted member identification key, and may confirm that the authentication of the user device SS1 requesting the login in step S1005 is completed. In step S1102, the affiliate member management server SP1 may transmit a response message to the login request to the user device SS1. In another embodiment, instead of the affiliate member management server SP1, in step S1100, the blockchain platform server BCS may transmit a response message to the login request of the user device SS1 to the user device SS1.

In another embodiment, instead of the one-time password, the user device SS1 transmits the blockchain account ID and password to the blockchain platform server (BCS) through the blockchain login interface in step S1020, and the blockchain platform server (BCS) sends the above User authentication is performed through the blockchain account ID and password, and when the next user authentication is completed, the member identification key can be encrypted and delivered to the affiliate member management server (SP1) immediately.
