Problems solved by technology

However, this method is not safe in the face of many brute force cracking software.
In addition, there is another way to use the mobile phone's location service (such as Apple's "Find My iPhone app" and Google's "Android Device Manager") to solve the security of the data stored on the phone after the smartphone is lost, but The premise of this method is that the lost mobile phone needs to be online at all times, and it cannot prevent illegal users from reading sensitive data files on the mobile phone.

Embodiment 1

[0056] Embodiment 1 provided by the present invention is a process scheme for adding a new password management item in the password manager using the IMSI of the SIM card as the unique identification information. Specifically include the following steps:

[0057] (1) Check the validity of the SIM card

[0058] The user enters the password for the password manager to enter the password manager software.

[0059] The password manager checks whether the mobile network of the SIM card of the current mobile phone is successfully connected, and if successful, proceeds to the next step; otherwise, accesses the password information file stored locally in the mobile phone, and deletes the file directly if it exists. Then it will return prompt information such as "SIM card is invalid, the current password manager software cannot be used!";

[0060] (2) New network resource password management information

[0061] After the mobile phone user legally enters the password manager, enter ...

Embodiment 2

[0069] Embodiment 2 provided by the present invention is a flow scheme for querying password management items by the password manager using the IMSI of the SIM card as the unique identification information. Specifically include the following steps:

[0070] (1) Check the validity of the SIM card

[0071] The user enters the password for the password manager to enter the password manager software.

[0072] The password manager checks whether the mobile network of the SIM card of the current mobile phone is successfully connected, and if successful, proceeds to the next step; otherwise, accesses the password information file stored locally in the mobile phone, and deletes the file directly if it exists. Then it will return prompt information such as "SIM card is invalid, the current password manager software cannot be used!";

[0073] (2) Enter the network resource identifier to be queried

[0074] After the user legally enters the password manager, he enters the Web resource...

Abstract

The invention relates to a method for safely storing password information based on SIM card information and a password manager. The method is applicable to an electronic device containing a SIM card, and the steps include: 1) checking the validity of the SIM card in the electronic device; 2) extracting the unique identification information of the SIM card for a valid SIM card; 3) extracting the unique identification information of the SIM card The identification information is bound with the password information of the user's network resource; 4) The binding result generated in step 3) is stored locally. The password manager includes a password acquisition module, a password management module, a password binding module and a password unbinding module. The invention binds the password information of the user's network resources with the information of the SIM card through hardware, provides the user with convenient and easy-to-use password management services, and at the same time ensures the security of the user's password information well.

Description

technical field [0001] The invention belongs to the technical field of network security, and in particular relates to a method for safely storing password information based on SIM card information, and a password manager, which is suitable for electronic devices including SIM cards, such as smart phones and the like. Background technique [0002] At present, the well-known network resource security mostly adopts the method of "username + password" to ensure the security of user information. It is the management of network resource passwords. If the user's network resource passwords are all the same, there will be a security risk of "single-point breakthrough" of user information; on the contrary, if the user uses different network resource passwords, there will be a problem of too many passwords that are difficult to remember. [0003] In order to solve the above problems, there are currently two main solutions, one is an online password manager, such as LastPass. The feat...
