The invention provides a data protection method and device of terminal equipment, and belongs to the technical field of a computer. The data protection method of the terminal equipment comprises the following steps of obtaining a first MD5 value of a first application program of the terminal equipment; obtaining a second MD5 value of data of a first application program of a server; if the first MD5 value is different from the second MD5 value, updating the data of the first application program of the terminal equipment into first data. The data protection method and device of the terminal equipment provided by the invention have the advantage that the data security of the application program of the terminal equipment is improved.
Description
technical field [0001] The present invention relates to the field of computer technology, in particular to a data protection method and device for terminal equipment. Background technique [0002] With the widespread application of the Internet, terminal device applications are widely favored and used by people because of their convenience and speed. [0003] More and more terminal device applications involve services with higher security requirements, such as payment services, especially financial planning applications and banking business handling applications. In the existing technology, in order to improve security, data security verification is usually deployed on the server, the data of the terminal device is encrypted and then transmitted to the server, and the server decrypts and verifies the consistency of the data to determine whether the data has been tampered with during transmission. Thereby improving data security. However, since the user can obtain the file ...
