The credential entries include, but are not limited to, titles, account numbers, passwords, destination application names, destination web addresses, remark information, whether it is a credential for secure access, and the like. The credentials are securely and seamlessly docked to the target application even though the user no longer needs to worry about password leakage in public places.
Defining a security access rule for the credential entry, associating the credential entry with an authentication fingerprint, wherein different credential entries may be associated with different fingerprints, and after enabling, accessing the credential entry requires fingerprint authentication.
A context detection module is introduced into the mobile terminal to identify the password input context, and when the password input interface is detected, a new option is displayed in the mobile terminal to enable the user to select a predefined credential from the credential vault instead of invoking a common IME for input operation.
To make the recognition mechanism more versatile, the recognition of the password input context by the context detection module may be implemented using OCR word recognition or a machine learning model of the password input screen. A typical login window contains feature words such as "user name", "password", "account", "login", etc., so that an appropriate algorithm can be designed based on OCR and custom rules to help detect password entry context. The recognition mechanism can be extended to any software product that is input by an input method running on a fingerprinting device.
When the user selects the credential entry, only the title list of the credential entry is displayed, and the other credentials in the credential entry except the title are not displayed on the screen.
An access verification module is introduced into the mobile terminal, and after a user selects a credential entry of a specific title, the credential vault control module needs to perform fingerprint identity verification on the selected credential entry to retrieve detailed information, and the access verification module performs fingerprint identity verification. And after the authentication is passed, the user may further select the credential content associated with the credential entry, and the selected field (e.g., password) will be filled into the target text box of the target application.
An access manager is introduced in the mobile terminal, and after the access verification is passed, the access manager retrieves the detailed information of the selected credential entry from the credential vault.
As shown in fig. 4, the method for inputting the security password specifically includes the following steps:
step 1: the user starts the mobile application program, clicks in the login window, and triggers the process of inputting the password through the keyboard;
step 2: the IME hook module intercepts the call to the IME and redirects the call request to the credential vault control module;
step 3: the certificate safe control module calls the context detection module to analyze whether the input focus is in a login window requiring password input, and returns the detection result to the certificate safe control module;
step 4: for a password input request, the credential vault control module selects to establish an input connection with a target application;
step 5: the credential vault control module displays a credential selection menu for a user to select predefined credential entries;
step 6: the credential vault control module invokes the access verification module to verify the user fingerprint to ensure that the user has access rights of the corresponding entry;
step 7: for legal access, the credential vault control module invokes an access manager to retrieve detailed information of the credential entry from the credential vault;
step 8: the credential vault control module sends the password to a password input box of the target application;
step 9: the target application program sends a response to the input method system service to end the input transaction;
if any of steps 2-9 fails, the IME hook module receives the corresponding response and notifies the input method system that the service continues according to the normal input method flow. (as shown in steps 10-11 of fig. 4).
