Embodiment Construction

[0019] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0020] figure 1 It shows a flow chart of a tamper-proof inspection method for database key data according to an embodiment of the present invention, including the following steps:

[0021] S102, setting a check code in the record of the database, the check code is generated according to the key data in the record;

[0022] S104, when checking, generate the ciphertext of the key data;

[0023] S106, comparing the ciphertext with the check code, and determining whether the key data has been tampered with according to the comparison result.

[0024] The above-mentioned embodiment generates ciphertext by combining the key data with the key configured in the system, compares the ciphertext with the check code generated in the same way stored in the database, and determines whether the key data has been tampered with according to the com...

Abstract

The invention provides a tamper-proofing test method of key data in the database, which comprises following steps: arranging a check code in the record of the database, wherein the check code is generated according to the key data in the record; generating a cipher text of the key data when testing; comparing the cipher text and the check code, and determining if the key data is tampered with according to the comparing result. In the state of guaranteeing the safety of the system key and after the database is externally tampered with, the external attack which tampers with the data can't obtain a key value and can't fake the check code matched with the core data, thereby the tamper-proofing test method of the invention can fundamentally guarantee the accuracy of the data, and overcome theproblems that the prior art is the tamper-proofing scheme aiming at web page, and when the core data stored in the database server is tampered with, the prior art can't test and monitor the tampered core data.

Description

technical field [0001] The invention relates to the field of radio and television, in particular to a tamper-proof checking method for key data in a database. Background technique [0002] With the continuous development of computer technology and the popularization of the Internet, information technology has extended to every corner of our work and life. In information technology, a large amount of stored data is the main basis for the realization of various system functions. When these data are wrong, the impact is very serious, especially if the sensitive data of financial companies such as banks are damaged and Tampering, then the loss is incalculable. Therefore, in the face of the threats of various human factors such as hackers, information theft, virus Trojan horses, and employee malfeasance, a technology that can ensure data security is very much needed. [0003] The existing technical solutions are all aimed at anti-tampering solutions for pages, which are mainly ...
