Problems solved by technology

[0003] Repairing damaged compressed files is one of the important applications in the field of data security inspection. ZIP format storage files are one of the commonly used compressed file formats. They are widely used in Windows, Linux, Unix and other operating systems. With the rapid development of computers and the Internet, With the development, ZIP files have gradually become the mainstream file format for data storage and transmission. However, due to disk damage, network transmission, virus damage, etc., the data stored in ZIP is damaged, causing many users to lose important data.
[0004] The common damage situation of ZIP comprises: the loss of file byte (as the error that network transmission, disk copy take place) or increase (virus infection, wrong IO operation) etc.; Most of the repair methods use the repair method based on the file header, and focus on the repair of the file format, but it cannot be effectively repaired for the case of no file header or missing data

Embodiment 1

[0040] The purpose of this embodiment is a method of damaged compression packet repair.

[0041] A damage to damage compression package, including:

[0042] Get the file structure data of the compressed package, and determine the damage type of the file structure;

[0043] The file structure is pretreated according to the damaged type;

[0044] The multi-dimensional analysis of the file structure generates the correct file structure and realizes the repair of the compression package format;

[0045] Based on the repaired compression package format, subfile decompression according to the file sequence; where the decompression process is repaired according to the data in the subfiles in the compression coding type;

[0046] Get the repaired compressed file.

[0047] Specifically, the present disclosure will be described in detail below with reference to the accompanying drawings:

[0048] In the present embodiment, the method of the present disclosure will be described as an example...

Embodiment 2

[0085] The purpose of this embodiment is a damaged compression package repair system.

[0086] A damaged compression package repair system, including:

[0087] Data acquisition unit, which is used to obtain file structure data of the compressed package, and determine the damage type of the file structure;

[0088] The pretreatment unit is used to prepare the file structure according to the damage type;

[0089] File format modification unit, which generates the correct file structure based on the multi-dimensional analysis of the file structure, and realizes the repair of the compression package format;

[0090] The data area modification unit is used to perform sub-file decompression based on the file sequence in the file; where the decompression process is fixed according to the data in the subfile according to the compression encoding type;

[0091] The result acquisition unit is used to obtain a repaired compressed file.

[0092] In more embodiments, it is also provided:

Abstract

The invention provides a damaged compressed package repairing method and system, and the method comprises the steps: obtaining file structure data of a compressed package, and judging the damage type of a file structure; preprocessing a file structure according to the damaged type; generating a correct file structure based on multi-dimensional analysis of the file structure, and repairing the format of the package; decompressing the sub-files according to the file sequence based on the restored compressed package format, wherein in the decompression process, the data in the sub-file is repaired according to the compression coding type; and obtaining the repaired compressed file.

Description

Technical field [0001] This disclosure belongs to the technical field of compression package repair, and more particularly to a damaged compression package repair method and system. Background technique [0002] The statement of this section is merely the background technology information related to the present disclosure, which is not necessarily constituted in prior art. [0003] Repair damaged compressed files is one of the important applications in the field of data security inspections. Zip format storage files are one of the commonly used compressed file formats, extensive applications in operating systems such as Windows, Linux, UNIX, with the computer, and the Internet Development, ZIP files have gradually become the mainstream file format of data storage and transmission, but due to disk corruption, network transmission, viral damage, etc., the data stored in ZIP is damaged, causing many users to lose important data. [0004] The common damage of ZIP includes: loss of fi...
