These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0037] Figure 1 The flowchart of a method for obtaining private data provided by an embodiment of this application is shown, as Figure 1 shown, this method mainly may include:

[0038] Step S110: Send a request to obtain the first data list to the server and receive the first data list returned by the server. The first data list includes the data identifiers of the data that the data user has the right to use;

[0039] Step S120: Obtain the second data list submitted by the user based on the first data list and send the second data list to the server, so that the server returns authorization information to the client based on the second data list;

[0040] Step S130: Receive the authorization information returned by the server and send the authorization information to the data user, so that the data user obtains the user data corresponding to the second data list based on the authorization information.

[0041] In the embodiments of this application, the data user may be an institution that needs the user to provide personal data. For example, when the user applies for a loan business from a bank institution, the data user is the bank institution.

[0042] The user data can be the user's privacy data, such as the user's ID number, home address, property information, etc.

[0043] The server can maintain a first data list of data users. The first data list includes the data identifiers of the user data that the data users have been approved to have the right to use.

[0044] When it is necessary to provide user data to the data users, the user can request the first data list of the data users from the server through the client.

[0045] The client can display the first data list to the user for the user to select from the data included in the first data list to obtain a second data list. The second data list lists the data identifiers of the data to be provided to the data users.

[0046] After receiving the second data list provided by the user, the server can authorize the second data list and return the authorization information to the client. The authorization information can be in the form of an authorization code.

[0047] The server can also store the relevant information of the user and the second data list, that is, record the behavior of providing personal privacy data.

[0048] After receiving the authorization information, the terminal device can provide the authorization information to the data user. The data user can request the data corresponding to the data identifiers in the second data list from the data platform storing the user privacy data based on the authorization information. The data platform can be a secure server storing privacy data.

[0049] The method provided by the implementation of this application includes: obtaining a first data list by sending a request for the first data list to the server and receiving the first data list returned by the server. The first data list includes the data identifiers of the data that the data users have the right to use, obtaining the second data list submitted by the user based on the first data list, and sending the second data list to the server so that the server returns authorization information to the client based on the second data list, receiving the authorization information returned by the server, and sending the authorization information to the data user so that the data user can obtain the user data corresponding to the second data list based on the authorization information. Based on this solution, it is possible to facilitate the use of the user's personal privacy data and ensure the security of the user's personal privacy data.

[0050] In an optional manner of the embodiment of this application, obtaining the second data list submitted by the user based on the first data list includes:

[0051] Generating a check box interface based on the first data list and displaying the check box interface to the user;

[0052] Determine a second data list based on the user's ticking operation on the first data list in the ticking interface.

[0053] In an embodiment of the present application, the first data list can be displayed by providing a ticking interface, that is, the data in the first data list are shown one by one on the ticking interface, and the user can tick according to needs.

[0054] Specifically, while guiding the user to tick the data, the user can also be guided to read and tick the usage statement and disclaimer clause, and submit the selected second data list by clicking the consent authorization button.

[0055] In an alternative manner of an embodiment of the present application, sending the second data list to the server includes:

[0056] Authenticate the user;

[0057] If the authentication is passed, send the second data list to the server.

[0058] In an embodiment of the present application, before submitting the second data list to the server, the user can also be authenticated, such as face recognition of the user, to ensure the security of data usage. After the authentication is passed, the second data list can be sent to the server.

[0059] In an alternative manner of an embodiment of the present application, the data identifier corresponds to the sub-data obtained by splitting the user data.

[0060] Among them, the data granularity of the user data may be relatively large, that is, it contains a large amount of data. In actual use, the data user may only need a part of the data. Therefore, if the data is directly provided to the data user, it will cause the data user to obtain unnecessary user data, which is not conducive to the security and privacy of user data.

[0061] In an embodiment of the present application, the user data is split into sub-data, and the sub-data is authorized for use, which improves the usage accuracy of the data and ensures the privacy and security of user data.

[0062] As an example, the user data is the user's property information, and the sub-data obtained by splitting can include the property address, property ownership certificate number, etc. Further, the property address can be further split, such as splitting out information such as the area where the house is located as sub-data.

[0063] In an alternative manner of an embodiment of the present application, obtaining a request for obtaining the first data list from the server includes:

[0064] In the embodiment of the present application, a request for obtaining a first data list can be sent to a server by scanning a QR code through a terminal device.

[0065] In actual use, when the method provided in the embodiment of the present application is applied to handling business in a bank, the QR code can be scanned by the user's terminal device (such as a mobile phone), or can be scanned by the bank's self-service terminal device.

[0066] In an alternative embodiment of the present application, the above method further includes:

[0067] After the data user obtains the user data corresponding to the second data list based on the authorization information, receive the usage details of the user data returned by the server, and display the usage details of the user data to the user.

[0068] In the embodiment of the present disclosure, after the user data is provided to the data user, the server can return the usage details of the user data to the user and the data user, so that the user can view the usage details of the data in a timely manner, and can timely discover whether there are errors in the used user data, or whether the data update is not timely, etc., and also enables the data user to verify the obtained user data.

[0069] Figure 2 The flowchart of another method for obtaining privacy data provided by the embodiment of the present application is shown, as Figure 2 shown, this method mainly may include:

[0070] Step S210: When receiving a request for obtaining a first data list sent by a terminal device, first return the first data list returned by the terminal device. The first data list includes data identifiers of data for which the data user has usage permissions;

[0071] Step S220: Receive a second data list submitted by the terminal device based on the first data list;

[0072] Step S230: Based on the second data list, return authorization information to the terminal device, so that the terminal device provides the authorization information to the data user, and so that the data user obtains the user data corresponding to the second data list based on the authorization information.

[0073] In the embodiment of the present application, the data user can be an institution that needs to obtain personal privacy data from the user. For example, when the user applies for a loan business from a bank institution, the data user is the bank institution.

[0074] In the server, a first data list of data users can be maintained. The first data list includes data types for which the data users have been approved and have the right to use, such as data identifiers of data like the user's ID number, home address, etc.

[0075] When it is necessary to provide the user's personal privacy data to the data user, the user can request the first data list of the data user from the server through the client.

[0076] The client can display the first data list to the user for the user to select from the data included in the first data list to obtain a second data list. The second data list lists the data identifiers of the data to be provided to the data user.

[0077] After receiving the second data list provided by the user, the server can authorize the second data list and return the authorization information to the client. The authorization information can be in the form of an authorization code.

[0078] After receiving the authorization information, the terminal device can provide the authorization information to the data user. The data user can request the data in the second data list from the data platform storing the user's privacy data based on the authorization information. This data platform can be a confidential server storing privacy data.

[0079] In the embodiments of the present application, the data interactions between the server and the client of the terminal device, and between the data user and the data platform storing the privacy data can all be implemented based on blockchain smart contracts. Due to the decentralized feature of the blockchain, the data will be backed up on multiple nodes of the blockchain. Even if the data on a certain node is tampered with, it can be determined whether the data has been tampered with by comparing it with the data on other nodes. Therefore, it can prevent the data from being tampered with during the interaction process and ensure the accuracy of the data.

[0080] The method provided in the embodiments of the present application includes: obtaining a first data list by sending a request for the first data list to the server and receiving the first data list returned by the server. The first data list includes the data identifiers of the data for which the data user has the right to use. Obtaining the second data list submitted by the user based on the first data list and sending the second data list to the server so that the server returns authorization information to the client based on the second data list. Receiving the authorization information returned by the server and sending the authorization information to the data user so that the data user can obtain the user data corresponding to the second data list based on the authorization information. Based on this solution, it is possible to facilitate the use of the user's personal privacy data and ensure the security of the user's personal privacy data.

[0081] In an optional manner of the embodiments of the present application, the above method further includes:

[0082] Associate and store the second data list and the user's identity information.

[0083] Among them, the server can also store the user's relevant information with the second data list, that is, record the behavior of providing personal privacy data.

[0084] In an optional manner of the embodiments of the present application, the above method further includes:

[0085] Return the usage details of the user data to the terminal device and / or the data user.

[0086] In the embodiments of the present application, after the user data is provided to the data user, the server can return the usage details of the user data to the user and the data user, so that the user can view the usage details of the data in a timely manner, and timely discover whether there are errors in the used user data, or whether the data update is not timely, etc., and also enable the data user to verify the obtained user data.
