Description

Technical Field

[0001] The present invention relates to the field of data processing technology, and in particular to a method and system for implementing cross-device password management based on Bluetooth technology. Background Art

[0002] With the rapid development of Internet technology, people need to register more and more website or application accounts. In order to prevent data security, people need to record a large number of passwords and log in to a large number of different websites every day, which brings great inconvenience to people.

[0003] Currently, most websites and applications still rely on traditional account and password login methods. Users must remember their username and password for each website or application and manually enter them each time they log in. This not only increases the user's memory burden but also poses the risk of password leakage. Furthermore, some existing password managers require internet access to synchronize across multiple devices, indirectly increasing the risk of leakage. Once a password is leaked, the security of a user's accounts across multiple websites or applications will be compromised, posing a significant risk to users.

[0004] Therefore, there is an urgent need for a safe and reliable password management and automatic login method that can effectively solve the pain points of users recording a large number of passwords and logging into a large number of websites, allowing users to achieve automatic login while securely managing their passwords, thereby improving user experience. Summary of the Invention

[0005] The purpose of the present invention is to provide a method and system for cross-device password management based on Bluetooth technology to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a method for cross-device password management based on Bluetooth technology, including a software mutual trust step, and the specific process is as follows:

[0007] Terminal 1 turns on the Bluetooth function, and its software randomly generates a verification code;

[0008] Terminal 2 turns on the Bluetooth function and enters the verification code of Terminal 1 on Terminal 2. The software of Terminal 2 randomly generates a string of characters or a random QR code as a temporary key;

[0009] Terminal 1 turns on Bluetooth and pairs with Terminal 2's Bluetooth. After pairing is successful, Terminal 1 scans or enters a temporary key through software to obtain Terminal 2's temporary key.

[0010] Terminal 1 generates a new key 1, combines the generated verification code with key 1, encrypts it with the temporary key of terminal 2, and sends it to terminal 2 for mutual trust verification;

[0011] After receiving the mutual trust verification information, terminal 2 decrypts it using the temporary key provided to verify whether the verification code is correct. If the verification code is correct, it saves terminal 1's key 1 and regenerates a section of terminal 2's key 2;

[0012] Terminal 2 encrypts the newly generated key 2 with key 1 and returns it to Terminal 1;

[0013] Terminal 1 decrypts the data from Terminal 2 using its own Key 1 and obtains Key 2 of Terminal 2. This completes the key exchange between the two terminals, and both parties obtain each other's keys.

[0014] Finally, terminal 1 encrypts the verification code with key 2 and sends it to terminal 2. After receiving the data, terminal 2 uses key 2 to decrypt it and determine whether the verification code is consistent. If it is consistent, mutual trust is established.

[0015] Preferably, the data synchronization function is realized on the basis of completing the mutual trust of the software, and the specific process of data synchronization is as follows: Terminal 1 initiates a data synchronization request, and Terminal 2 prompts whether to synchronize the data; if Terminal 2 chooses not to agree, Terminal 2 returns a rejection reply, and the process ends; if Terminal 2 chooses to agree, Terminal 2 returns an agreement reply; After receiving the agreement reply, Terminal 1 first decrypts the local data, and then encrypts the data with the key 1 of Terminal 1 and sends it to Terminal 2; After receiving the encrypted data, Terminal 2 decrypts it with the key 1, and merges the acquired data with the original data; After completing the data merger, Terminal 2 encrypts the data with the key 2 and sends it to Terminal 1; After receiving the merged package, Terminal 1 decrypts it with the key 2, and merges the acquired data with the original data, thereby completing the data synchronization.

[0016] Preferably, it includes a control login step of automatically logging in terminal 2 by controlling terminal 1, and the specific process is as follows: terminal 1 sends a command to log in to a certain application to terminal 2 via Bluetooth; after receiving the command, terminal 2 searches for the corresponding application information from the password list; if terminal 2 does not find the relevant application, it returns an error message; if terminal 2 finds the corresponding application, it controls the relevant application through the software application of terminal 2 to perform a login operation; terminal 2 automatically polls the application usage, and if the user has not operated the application for a long time, terminal 2 automatically closes the application and clears the relevant cache records; terminal 2 automatically polls the application usage, and if it is found that the user has closed the application, terminal 2 automatically clears the relevant operations.

[0017] Preferably, it includes an automatic password management step, and the specific process is as follows: the password management software on the terminal polls the password that has been set to automatic management; if the password has reached the update condition, it automatically logs in to the application and jumps to the password change interface; obtains the old password from the password library, decrypts the password, and automatically generates a new password for standby; automatically enters the new and old passwords into the password modification interface input box and automatically submits; after the modification is successful, the software automatically replaces the old password and resets the next update time.

[0018] Preferably, software mutual trust, data synchronization, control login and automatic password management functions are comprehensively utilized to realize cross-device password management through the following steps: first execute the software mutual trust step described in claim 1 to complete the establishment of mutual trust between terminal 1 and terminal 2; based on the established mutual trust relationship, execute the data synchronization step described in claim 2 to realize the synchronous update of data between terminal 1 and terminal 2; after the data synchronization is completed or under specific needs, execute the control login step described in claim 3, control terminal 2 to automatically log in through terminal 1, and realize the incognito browsing privacy protection function; regularly execute the password automatic management step, and poll, update, and replace the password that has been set for automatic management through the password management software on the terminal to realize automatic management of the password.

[0020] Terminal 1 turns on the Bluetooth function, and its built-in software randomly generates a verification code;

[0021] Terminal 2 also turns on the Bluetooth function. The user enters the verification code generated by Terminal 1 on Terminal 2. The software of Terminal 2 then generates a string of characters or a random QR code as a temporary key.

[0022] Terminal 1 turns on Bluetooth and pairs with Terminal 2's Bluetooth. After pairing is successful, Terminal 1 obtains Terminal 2's temporary key by scanning with software or manually entering the temporary key.

[0023] Terminal 1 generates a new key 1, combines the generated verification code with key 1, encrypts the combined information using Terminal 2's temporary key, and then sends the encrypted information to Terminal 2 for mutual trust verification;

[0024] After receiving the mutual trust verification information, terminal 2 uses the previously provided temporary key to decrypt and verify whether the verification code is correct. If the verification code is correct, it saves terminal 1's key 1 and regenerates a section of terminal 2's key 2;

[0025] Terminal 2 encrypts the newly generated key 2 with key 1 and returns it to Terminal 1;

This function is implemented through the following modules and steps: Initiate synchronization module: Terminal 1 initiates a data synchronization request, and Terminal 2 pops up a prompt box to ask the user whether to synchronize data; Reject synchronization module: If the user of terminal 2 chooses not to agree to synchronization, terminal 2 returns a rejection response and the process ends; Agree synchronization module: If the terminal 2 user chooses to agree to synchronization, the terminal 2 returns an agreement reply; Data encryption and sending module: After receiving the consent reply, terminal 1 first calls the local decryption module to decrypt the local data, then encrypts the data using key 1 of terminal 1 and sends it to terminal 2; Data decryption and merging module: After receiving the encrypted data, terminal 2 decrypts it using key 1 and calls the data merging module to merge the acquired data with the original data; Encrypted return module: After completing data merging, terminal 2 encrypts the data using key 2 and sends it to terminal 1; Final merging module: After receiving the merged package, terminal 1 decrypts it using key 2 and calls the local data merging module to merge the acquired data with the original data, thus completing data synchronization.

8. A system according to claim 7, characterized in that: The control login module that controls terminal 2 to automatically log in via terminal 1 implements the following steps: Command sending module: Terminal 1 sends a command to log in to an application to Terminal 2 via Bluetooth; Application search module: After receiving the command, terminal 2 searches for the corresponding application information from the password list; Error feedback module: If terminal 2 does not find the relevant application, it returns an error message; Automatic login module: If terminal 2 finds the corresponding application, the software application of terminal 2 controls the relevant application to perform the login operation; Long-term inactivity processing module: Terminal 2 automatically polls application usage. If the user does not operate the application for a long time, Terminal 2 automatically closes the application and calls the cache clearing module to clear the relevant cache records; Closed processing module: Terminal 2 automatically polls the application usage. If it is found that the user has closed the application, Terminal 2 calls the operation clearing module to automatically clear related operations.

9. A system according to claim 8, characterized in that: Contains the automatic password management module, which implements the following steps: Password polling module: The password management software on the terminal polls the passwords that have been set for automatic management; Update condition judgment module: If the password has reached the update condition, call the automatic login module to automatically log in to the application and jump to the password change interface; Password acquisition and decryption module: obtains the old password from the password library, decrypts the password, and calls the new password generation module to automatically generate a new password for standby use; Automatic submission module: automatically input the new and old passwords into the password modification interface input box and submit automatically; Password replacement and time setting module: After the modification is successful, the software automatically replaces the old password and calls the time setting module to reset the next update time.

10. A system according to claim 9, characterized in that: By comprehensively utilizing the software mutual trust module, data synchronization module, control login module, and automatic password management module, cross-device password management can be achieved through the following steps: Mutual trust establishment module: first call the software mutual trust module described in claim 1 to complete the mutual trust establishment between terminal 1 and terminal 2; Data synchronization module: Based on the established mutual trust relationship, the data synchronization module described in claim 2 is called to achieve synchronous update of data between terminal 1 and terminal 2; Control login module: When data synchronization is completed or under specific requirements, the control login module described in claim 3 is called to control terminal 2 to automatically log in through terminal 1, and the privacy protection module is called to implement the privacy protection function of incognito browsing; Automatic password management module: Regularly call the automatic password management module described in claim 4, and poll, update, and replace the passwords that have been set for automatic management through the password management software on the terminal to achieve automatic management of the passwords.
