A verification method for data destruction of storage media

Abstract

An embodiment of the present invention provides a verification method for data destruction of a storage medium, comprising: performing data destruction processing on a target storage medium to be destroyed; generating a first encrypted electronic signature according to extraction of data destruction characteristic information of the target storage medium; and According to the inherent attribute information extraction of the target storage medium, the second encrypted electronic signature is generated; based on the preset encryption algorithm, the first encrypted electronic signature and the second encrypted electronic signature are combined and encrypted, and the verification ciphertext sequence is generated and then written Enter the verification storage area specified in the target storage medium; when verifying and checking, decrypt the verification ciphertext sequence in the verification storage area, and check the generated decryption result with the explicit information on the storage medium to verify the target storage Data destruction information for the media. The method provided by the invention can solve the existing problem of data leakage due to manual negligence or intentional inaccurate verification through technical means.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of data destruction, and in particular to a verification method for data destruction of a storage medium. Background technique [0002] In view of the storage principle of magnetic media and data reading and writing methods, ordinary low-level formatting, data deletion and other methods cannot completely clear data; the hidden operation of the operating system and hard disk will produce residual data, in order to prevent criminals from using data residual to recover The original data information will cause the risk of security leaks. Before the hard disk is scrapped or sent for repair or donated, the hard disk data should be destroyed according to different confidentiality levels. [0003] At present, a corresponding label will be generated after the data of the magnetic medium is destroyed, and the information on the label includes information such as the properties and specificati...

Problems solved by technology

[0004] However, in actual operation, it is found that there are several problems in the existing verification method for the destruction of storage media data: (1) There are human errors or subjective and intentional misoperations, wrong labels are pasted indiscriminately, and the label information shows that it has been destroyed but the actual The problem that the destruction operation was not carried out led to the leakage of important data; (2) the label information is plain text information, which may easily lead to the exposure of the destruction information of the magnetic medium. If the label shows that the destruction information has not been completed, it is easy for illegal personnel to notice and steal the magnetic medium (3) The auditor relies too much on the label information. If the label falls off or is damaged during the processing, it will lead to the problem that the auditor cannot audit
