Problems solved by technology

[0004] In the existing technology, there is no effective method to fundamentally ensure the safe output of private data. The current method is to manually use the typesetting software to use the typesetting software to use the private data as a The picture is embedded in the file, so as long as you get this file, you can use various printing devices to output private data, which not only increases the time for the pre-production of the file, but more importantly, the security is very poor. files may be stolen, causing some security issues

Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0038] A method for processing private data based on digital printing, comprising the following steps:

[0039] In the first step, use the TDES encryption algorithm to encrypt the Tiff format source file of the private data, and generate a png format preview image of the private data. The encryption algorithm may also be an encryption algorithm such as DES, PBOC or MAC.

[0040] The second step is to set up a super administrator, and the super administrator will add dispatchers, operators and authentication information. Authentication information includes information index, user name, password (non-plaintext password), private data ID, time limit, and number of times limit.

[0041] The above user's password is encrypted with MD5 or Base64 encryption algorithm. The user's clear text password does not exist in the database. And there is no clear text...

Abstract

The related private data processing method and system comprise: based on computer and output device, before real printing or last step of printing, combining certification information set by user with private data to output or print. This invention can improve data security and benefit to corresponding department on sensitive data output or print.

Description

technical field [0001] The invention belongs to the technical field of computer information processing, and in particular relates to a processing method and system for private data based on an output device. Background technique [0002] With the advent of the information age, the current printing field has presented many new features. For small-volume, time-sensitive, personalized printing, especially for departments with high confidentiality requirements, traditional printing has become less and less suitable for its requirements. As a government department with high confidentiality requirements, it is hoped that there can be a relatively safe output method for those particularly sensitive or confidential data. For example, the official seal of the government cannot be printed out casually. [0003] In addition to government agencies, higher requirements have been placed on the output of sensitive data in some personalized printing, including the printing of various perso...
