Print encryption method, printer data collection and analysis method, and print scanning device

Abstract

The invention belongs to the technical field of printing encryption, and in particular relates to a printing encryption method, a printer data collection and analysis method and a printing scanning device. According to the printing encryption method, encryption symbols, interference symbols and their quantity are set according to the input password and preset password arrangement rules; according to the number of digits of the input password, preset symbol layout rules, etc., an electronic document to be printed is generated. The printer data acquisition and analysis method includes: identifying symbols in the image to be decrypted, determining the number of digits of the password according to the identified symbols and preset symbol layout rules; determining the digits of the identified symbols according to the determined number of digits of the password Encrypt symbols, and count the number of encrypted symbols to obtain passwords; the method and device can realize encryption or document decryption through a printer, and have the characteristics of simple encryption method and no need to increase additional printing costs, and can be effectively applied to a large number of documents. Encrypting and decoding.

Description

technical field [0001] The invention belongs to the technical field of printing encryption, and in particular relates to a printing encryption method, a printer data collection and analysis method and a printing scanning device. Background technique [0002] There are currently two ways to encrypt documents, one is the identifiable anti-counterfeiting marks prefabricated on paper, such as the ultraviolet fiber on the passport and the security thread on the RMB, and the other is the MRZ code on the passport and the encrypted QR code, etc. Although the shape of the logo can be seen, the anti-counterfeiting password of the content it represents cannot be read. [0003] These two passwords have a high degree of confidentiality and security, but they are not suitable for daily use, especially for documents that need to be encrypted with many pages. The encryption methods prefabricated on paper such as ultraviolet fibers will cause high encryption costs, while MRZ codes and QR cod...

Problems solved by technology

[0006] The applicant found that the existing encryption methods are either expensive or difficult to interpret, which greatly restricts the use of existing encryption methods, especially not applicable to documents with relatively large encryption volumes such as doctor's orders and wills.
