Abstract

The invention discloses a method for deeply analyzing data based on a white list mechanism, comprising the following steps: building a white list, building a matching feature code list, reading a data file to be analyzed, inspecting whether a register item corresponding to the type of the file exists in the white list, reading the feature code of a file inspected by the white list, generating a block fingerprint, bonding the block fingerprint on data steam, transmitting the data steam to a storage node, receiving the data steam, checking and comparing the data steam, deciphering with a public key at a transmitting end and checking the block fingerprint, and judging that the decrypted block fingerprint is the same as the block fingerprint bonded on the data steam. The method has the beneficial effects that the defects in the prior art are overcome, the drawbacks of the existing file analyzing and filtering method are avoided, and the method for deeply analyzing the data based on the white list mechanism is provided.

Description

technical field

[0001] The invention relates to a data depth analysis method based on a white list mechanism. Background technique

[0002] At present, informatization in life, study and work is becoming more and more popular, and the security of archiving or storing files is also paid more and more attention by people. Nowadays, the main problem in the process of archiving or storing files is that Some data analysis methods are not deep enough, and only analyze the suffix name of the data from the surface layer of the data, which allows users to store and archive file types that are not allowed, such as non-video or non-audio files (.3dmax / .doc / .ppt ... etc.), the traditional solution is simple file type filtering. If the suffix of non-video and audio files is changed, the system also allows storage and archiving. Contents of the invention

[0003] The purpose of the present invention is to solve the deficiencies of the prior art, avoid the drawbacks of the curre...

Embodiment Construction

[0018] Further describe the technical scheme of the present invention below in conjunction with accompanying drawing, as figure 1 , a method for in-depth analysis of data based on a whitelist mechanism, characterized in that: comprising the following steps:

[0019] (1) Create a whitelist, and each entry in the whitelist corresponds to a valid file type;

[0020] (2) Establish a matching feature code list, and each entry in the matching feature code list represents a valid file type feature;

[0021] (3) Read in the data file to be parsed, check whether the type of the file has a corresponding registration item in the white list, and discard the file if no corresponding registration item is found;

[0022] (4) Read the feature code of the file that has passed the whitelist check, and check whether there is a corresponding registration item from the matching feature code list. If the corresponding registration item cannot be found, discard the file;

[0023] (5) Generate the ...
