Embodiment Construction

[0034] In order to solve the problem that the existing technology cannot encrypt the application program database and easily cause data leakage, the present invention provides a database encryption and decryption method, device, storage medium and terminal. For further details. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] The first embodiment of the present invention provides a database encryption method, the method is applied to the terminal, its flow chart is as follows figure 1 As shown, it mainly includes steps S101 and S102:

[0036] S101. Encrypt the field to be encrypted in the database based on the key.

[0037] In the prior art, the field content stored in the database corresponding to the application program is displayed in plain text. When the mobile terminal is cracked, illegal users can easily obtain the plain text content in the database, resulti...

Abstract

The invention discloses a database encryption method and device, a database decryption method and device, a storage medium, and a terminal. The method comprises the steps of encrypting, based on secret keys, to-be-encrypted fields of a database; and mixing the secret keys according to a preset mixing manner, and storing the mixed secret keys. According to the method, the fields of the database areencrypted, and the secret keys are mixed, so that even if an unauthorized user cracks a mobile terminal and acquires database content, the user cannot acquire a correct secret key so as not to decrypt encrypted database fields, therefore, the database content is protected, the operating risk of the application is lowered, and the use safety for the user is improved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a database encryption and decryption method, device, storage medium and terminal. Background technique [0002] Along with the popularization of the use of mobile terminals, various application programs (APP, Application) are also enriching the functions of the mobile terminals, so as to meet various functional requirements of users. The database is an important part of the APP file, especially for various high school examination, answering, and evaluation APPs, and the corresponding content in the database is the object that needs to be protected. [0003] The databases used in existing mobile terminals (such as the lightweight cross-platform relational database SQLITE) usually do not have an encryption function, and the contents of the database fields are all displayed in plain text, which cannot be protected by encryption. When an illegal user cracks the mobile terminal an...
