The embodiments of the present application are further described in detail below with reference to the accompanying drawings.

Embodiment 1

As shown in FIG. 2, a flowchart of a method for processing sub-account information provided in Embodiment 1 of the present application includes the following steps:

S201: The master device logs in to the application through the primary account, and sends a sub-account information acquisition request to the server.

Applications here can refer to APP, websites, web pages, and the like. The user opens the login page of the APP, website, or webpage through the master device, and enters the login password of the primary account and the primary account on the login page to log in to the application.

In a specific implementation, the main device user can input the basic of the sub-account in the login application interface. Information, such as sub-accounts, sub-account processing rights (can provide options for users to choose), the number of sub-accounts, etc., and send this information to the server. Here, the sub-account can be created by the server in addition to the main device, that is, the server can generate each sub-account and its corresponding password information for the main device.

The server in the embodiment of the present application may refer to a server where the server of the application is located, or may be a server dedicated to providing password information. Generally, an application includes a server and a client. The server of the application may be deployed on the server that provides the password information in the embodiment of the present application, or may be deployed on other servers. The client of the application is deployed in the embodiment of the present application. On the master and child devices.

S202: The server acquires the sub-account information including the password information according to the sub-account information acquisition request, and transmits the sub-account information to the main device.

In a specific implementation, the server may randomly generate password information for the sub-account and save the information in the server. Then, the server may transmit the status information of the sub-account password creation success and the generated password information corresponding to each sub-account to the main device.

S203: The master device receives the sub-account information returned by the server, where the sub-account information includes the password information of the sub-account, and sends the password information to the sub-device.

In a specific implementation, after receiving the sub-account information returned by the server, the master device may automatically save the password information of the sub-account in the background, and then send the automatically saved password information to the sub-device in the background; in the process, the sub-account The password information is always invisible to the user. Preferably, the saved password information may be in an encrypted state, where the encryption may include the first encryption described below, or the first encryption and the second encryption.

In a specific implementation, after generating the sub-account information, the server may perform the first encryption on the sub-account information, and transmit the first encrypted sub-account information to the main device; the main device receives the first encrypted Sub-account information; the first encrypted password information corresponding to the sub-account is sent to the sub-device. Here, the sub-account information after the server performs the first encryption may include the sub-account and its corresponding password information, and the master device may directly send the first encrypted sub-account and its corresponding password information to the sub-device.

In addition, after receiving the first encrypted password information sent by the master device, the child device may first decrypt the password information by using the opened application. In a specific implementation, in the application, the client can only decrypt the password information from other clients, but cannot decrypt the password information from the server, so that the master device can receive the encryption status sent by the server. After the sub-account password information, the password information cannot be decrypted, which further enhances the security of the sub-account password information.

Preferably, after receiving the first encrypted sub-account information returned by the server, the master device may further perform second encryption on the password information of the sub-account, and send the second encrypted password information to the sub-device to further The security of the password transmission process is improved; after receiving the second encrypted password information sent by the master device, the child device performs second decryption and first decryption on the password information.

The master device can transmit the password information of the sub-account to the sub-device through various communication methods, such as Bluetooth, wireless fidelity (wifi), data connection, and the like. As a preferred implementation manner, the master device may send the password information of the sub-account to the sub-device through a Near Field Communication (NFC) data transmission channel.

Since the communication distance of the NFC is usually less than 10 cm, the password information of the sub-account can be transmitted through the NFC Peer-to-Peer (P2P) mode to ensure that the sub-account password information is transmitted by the primary account holder and the sub-account recipient. The confidentiality and integrity of the password information are ensured; and, based on the NFC transmission method, the entire transmission process can be completed by simply bringing the two devices close to each other, thereby eliminating the cumbersome long search and connection pairing process, thereby simplifying the user. Operation on mobile devices. In a specific implementation, the master device can establish an NFC data transmission channel with the child device by touching the child device. The touch process is a new type of interaction that simulates a handshake. It can be seen as a process of acceptance and confirmation, which can play a role of non-repudiation.

In a specific implementation, the decoding manner of decrypting the encrypted information in the encrypted state may be preset. In addition, the specific password transmission channel (such as an NFC data transmission channel, a Bluetooth data transmission channel, etc.) may also be set in the application. Corresponding decoding mode, the sub-device determines the decoding mode according to the cipher transmission channel that receives the cipher information, and uses the cryptographic information in the encrypted state based on the determined decoding mode. Decrypt. For example, the decoding mode corresponding to the NFC data transmission channel can be set. After the master device sends the password information to the child device through the NFC data transmission channel, the child device determines that the password information is from the NFC data transmission channel, and according to the NFC data transmission channel. The corresponding decoding method is used for decryption. In addition, the use permission of the decoding mode can be defined in the application. For example, only the password information is from the NFC data transmission channel, and the password information can be decrypted using the decoding method corresponding to the NFC data transmission channel, thereby further ensuring the security of the password.

In a specific implementation, after receiving the password information from the server, the master device may prompt the user without displaying the password, for example, by prompting changes in the brightness of the application interface (for example, when the master device initiates a request to the server) After that, the brightness of the application interface is dimmed. After receiving the password information fed back by the server, the brightness of the application interface is bright, indicating that the user can operate the application at this time, or directly prompting the user that the password is successfully obtained through the information, and can be sent to the child device. .

As a preferred implementation manner, the master device may also send the information of the application, such as the name or identifier of the application, to the child device, while transmitting the information of the sub-account (including the password information, the sub-account, and the like) to the sub-device. It can be a string used to trigger an open application, and so on. In this way, the child device can open the application based on the information of the application sent by the master device, and log in the sub-account based on the password information in the opened application, as described in detail with respect to S204. Of course, the child device can also actively open the application under the trigger of the user, and does not need the information sent by the master device to trigger.

S204: The sub-device receives the password information of the sub-account sent by the main device, and logs in the application based on the password information of the received sub-account.

In a specific implementation, after receiving the sub-account and the corresponding password information sent by the main device, the sub-device sends the received sub-account and the corresponding password information to the server for authentication based on the opened application.

The server compares the password information of the sub-account sent by the sub-device with the password information of the sub-account saved by the server. After determining that the two are consistent, the server confirms that the authentication is successful. At this time, the server allows the sub-device to successfully log in to the application. After the sub-device successfully logs in, you can set the initial password, which can be to modify the system default initial password, or set the initial password based on the default password. code.
