And judging whether the second user information is the user information of the user stored in the data request end.
If yes, sending a data query request to the data providing terminal.
And receiving a query result which is fed back by the data providing end and is aimed at the data query request.
Corresponding to the data query method applied to the data request end, in one embodiment of the invention, a data query method applied to the data providing end is also provided.
The data query method applied to the data providing end comprises the following steps:
receiving first user information of a user sent by a data request end, wherein the first user information is: and part of the preset user information which is stored by the data request terminal, used for identity verification or identification and used for the user.
And carrying out identity verification or identification on the user according to the first user information.
And under the condition that the authentication or the identification is successful, sending second user information to the data request end, wherein the second user information is: and the data providing end stores information in the preset user information except the first user information.
And receiving a data query request sent by the data request terminal when the data request terminal determines that the second user information is the user information of the user stored by the data request terminal.
Obtaining a query result aiming at the data query request, and sending the query result to the data request end.
In the above, when the user inquires the data from the data providing terminal through the data request terminal, the data request terminal only transmits the first user information to the data providing terminal and receives the second user information transmitted by the data providing terminal, the first user information and the second user information are respectively part of the preset user information, and the condition that all the preset user information is transmitted once does not exist, so that the user information of the user is not leaked to the data providing terminal in the condition that the user information of the user is not stored by the data providing terminal, thereby improving the safety of the user information.
The data query method and device provided by the embodiment of the invention are explained below through specific embodiments.
Referring to fig. 1, an embodiment of the present invention provides a flowchart of a first data query method, specifically applied to a data request end, where the method includes the following steps S101 to S105.
S101: and sending the first user information of the user to the data providing end.
The user can apply for service through the data request end and authorize the data request end to inquire data from the data providing end. For example, the user may apply for the loan service through the data request end, the data request end may be a banking server or a consuming financial institution server, the data providing end may be an operator server, and the user may authorize the banking server or the consuming financial institution server to query the user identity verification information or the communication information from the operator server.
The first user information is: and part of the preset user information which is stored by the data request terminal, used for identity verification or identification and used for the user.
Specifically, the data request end and the data providing end may both store user information of the user. The first user information may be one or more types of preset user information, and the fewer the user information contained in the first user information, the fewer the number of information leakage user information leakage occurs, and the higher the security of the user information, so that if the first user information only contains one type of information in the preset user information, the security of the user information is the highest.
For example, the preset user information may be a user name, a phone number, an identification card number, a bank card number, etc. The first user information is user name information, telephone number information or other multi-type user information, etc.
S102: and receiving second user information sent by the data providing end under the condition that the identity of the user is verified or identified successfully according to the first user information.
Wherein, the second user information is: and the data providing end stores information in the preset user information except the first user information.
For example, the preset user information is a user name, a phone number, a bank card number, and an identification card number of the user, and the first user information is the user name of the user, and the second user information may be preset user information other than the user name, such as phone number information, or phone number information and bank card number information, or all preset information other than the user name, such as phone number information, bank card number information, and identification card number information.
As the second user information can contain one or more types of information, if information leakage occurs in the process of sending the second user information from the data providing end to the data requesting end, the smaller the user information contained in the second user information, the smaller the quantity of the user information leakage, and the higher the safety of the user information, so that if the second user information only contains one type of information in the preset user information, the safety of the user information is the highest.
Specifically, if the data providing end stores the first user information of the user, the authentication or identification is successful.
S103: and judging whether the second user information is the user information of the user stored in the data request end, if so, executing the following step S104, and if not, ending the flow.
Specifically, the second user information is user information of the same user corresponding to the first user information, which is stored in the data providing terminal. If the second user information is the user information of the user stored in the data request end, the first user information and the second user information are the same as the corresponding user in the data request end and the data providing end, the user is indicated to pass the authentication or the identification, otherwise, the user is indicated to not pass the authentication or the identification.
S104: and sending a data query request to the data providing end.
Specifically, if the determination result in step S103 is yes, it is indicated that the user passes authentication or identification, and the data query request may be sent to the data providing terminal to perform data query.
S105: and receiving a query result which is fed back by the data providing end and is aimed at the data query request.
Specifically, the data providing end may query the data requested by the data requesting end in the stored data according to the data query request after receiving the data query request, and send the query result to the data providing end, so that the data requesting end receives the query result.
In the above, when the user inquires the data from the data providing terminal through the data request terminal, the data request terminal only transmits the first user information to the data providing terminal and receives the second user information transmitted by the data providing terminal, the first user information and the second user information are respectively part of the preset user information, and the condition that all the preset user information is transmitted once does not exist, so that the user information of the user is not leaked to the data providing terminal in the condition that the user information of the user is not stored by the data providing terminal, thereby improving the safety of the user information.
Referring to fig. 2, a flowchart of a second data query method is provided in an embodiment of the present invention.
Specifically, when the second user information is part of the preset user information which is stored in the data providing terminal and is used by the user and is not used for user authentication or identification, the preset user information is described to include user information which is not used for user authentication or identification. In contrast to the previous embodiment shown in fig. 1, the above step S104 may be implemented by the following steps S104A-S104C.
S104A: and selecting user information of the user from the preset user information which is stored by the data request end and is of the user and is except the first user information and the second user information, and taking the user information as third user information.
Specifically, the user information which is not used for user identity verification or identification is included in addition to the first user information and the second user information, so that the user information can be selected as third user information from the preset user information which is stored in the data request terminal and is other than the first user information and the second user information, and the user identity can be further verified or identified.
The third user information may be one or more of user information that is not used for user authentication or identification.
For example, the preset user information is a user name, a phone number, an identification card number, and a bank card number, the first user information is a user name, the second user information is a user identification card number, and the third user information may be a phone number and a bank card number.
S104B: and generating a data query request containing the third user information.
Specifically, a data packet including the third user information and the data query information may be generated as the data query request.
S104C: and sending the data query request to the data providing end, so that the data receiving end performs identity verification or identification on the user again according to the third user information, and performs data query on the data query request under the condition that the verification or identification is successful.
The above can be seen that after the user identity verification or identification is successful according to the first user information and the second user information, the data request end sends the third user information to the data providing end, so that the data providing end further verifies or identifies the user identity according to the third user information.
Referring to fig. 3, a flow chart of a third data query method is provided. In the case where the user information stored in the data requesting side and the data providing side is encrypted user information, the step S101 may be implemented by the step S101A, compared with the embodiment shown in fig. 1.
S101A: and sending the encrypted first user information to the data providing end.
Specifically, the encryption mode for encrypting the user information is the same encryption mode pre-agreed by the data request end and the data providing end.
For example, the encryption scheme may be MD5 or SHA 256.
The above step S102 may be implemented by step S102A.
S102A: and receiving encrypted second user information sent by the data providing end under the condition that the user is successfully authenticated or identified according to the encrypted first user information.
The above step S103 can be implemented by step S103A.
S103A: and judging whether the encrypted second user information is the encrypted user information of the user stored in the data request end.
Because the data request end and the data providing end encrypt the stored user information in the same encryption mode, the same data is encrypted by the data request end and the data providing end, and the obtained encrypted data is the same. Therefore, if the encrypted second user information is the encrypted user information of the user stored in the data request end, the second user information is the user information of the user stored in the data request end.
Further, in the case where the encrypted third user information is included in the data query request, the data query request including the encrypted third user information may be transmitted to the data provider.
Therefore, the data transmitted between the data request end and the data providing end are all encrypted data, so that the data security in the data transmission process is improved.
Referring to fig. 4, an embodiment of the present invention provides a flowchart of a fourth data query method, specifically applied to a data providing end, where the method includes the following steps S401 to S405.
