Embodiment 1

[0042] Embodiment 1 of the present application provides an irreversible text, letter and digital information encryption comparison method, such as figure 1 shown, including the following steps:

[0043] Step 110, constructing a dictionary of codes for text, letters and numbers;

[0044] Among them, text, letter and number information includes but not limited to 28 basic strokes, 26 letters, numbers from 0 to 9, etc., and may also include combined strokes that are not mandatory;

[0045] In the embodiment of this application, building a code dictionary specifically includes two methods:

[0046] ①Pixelize text, letters and numbers, extract the total number of pixels as codes, and build a code dictionary;

[0047]Construct a dictionary of code names, specifically, first pixelate the basic strokes, letters, numbers, and combined strokes, and then extract the pixel sum of each basic stroke, letter, number, and combined strokes after pixelization, and use it as the corresponding ...

Abstract

The invention discloses an irreversible character, letter and number information encryption comparison method and device. The method comprises the following steps: constructing a code dictionary of character, letter and number information; codes in the code dictionary are encrypted, the codes are converted into code passwords, and carrier character feature tags are added; constructing a carrier character dictionary, selecting carrier characters from the carrier character dictionary, and injecting a pixel point group of a code password or password group with a label into effective pixel pointsof the carrier characters; comparing different carrier characters generated by encrypting the same information by the multi-party users, and calculating the similarity of the encrypted information carried by the different carrier characters; and if the identity of the carrier character user is legal, comparing and searching the encrypted information according to the carrier characters. By adoptingthe technical scheme of the invention, irreversible code password arrangement and pixel point code arrangement are formed, encrypted information comparison under the condition that multi-party information sources are not leaked is protected, and the method has a wide application space in the aspect of unified authentication.

Description

technical field [0001] The present application relates to the technical field of information security, in particular to a method and device for encrypting and comparing irreversible characters, letters and numbers. Background technique [0002] In the social structure where the information industry has become a national pillar industry, information acquisition, processing, transmission, exchange and service have become an all-time and ubiquitous business model. At present, the information and Internet industry led by business models is evolving rapidly, and the demand for new technical methods is also increasing. [0003] Existing data processing and transmission generally ensure data security through encryption and decryption, without processing the data itself. Therefore, if the data encryption and decryption process is cracked, the data will be easily stolen. Based on this, the present application constructs a method capable of processing the data itself to ensure data s...
