Verification method for data destruction of storage medium

Abstract

The embodiment of the invention provides a verification method for data destruction of storage medium. The method comprises the following steps of: destructing data of a target storage medium to be subjected to data destruction; extracting and generating a first encryption electronic feature code according to data destruction feature information of the target storage medium and extracting and generating a second encryption electronic feature code according to inherent attribute information of the target storage medium; based on a preset encryption algorithm, performing combined encryption on the first encryption electronic feature code and the second encryption electronic feature code, and generating a verification ciphertext sequence and writing the sequence into a specified verification storage area in the target storage medium; while verifying and checking, decrypting the verification ciphertext sequence in the verification storage area, and checking the generated decryption result with display information on the storage medium to verify the data destruction information of the target storage medium. With the method provided by the invention, by technological means, an existing problem of data leakage caused by artificial negligence or deliberate inaccuracy of verification can be solved.

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
