Information protection method and system of sensitive content data

Abstract

The invention relates to an information protection method and system of sensitive content data. The method comprises the first step of designing a genetic word stock file, wherein the file comprises characters and security codes of the characters, and a several-for-one mapping relation is formed between the security code of each character and a standard code of the character in a standard word stock; the second step of setting the genetic word stock file into an embedding-forbidding mode, and conducting whole encryption and afterwards storing the encrypted file into a server instead of conducting installing directly in an operating system of a client side; the third step of converting the standard codes in the standard word stock into the security codes of corresponding characters in the genetic word stock, and converting the characters of the standard codes corresponding to the sensitive content data which needs to be protected into the characters of the security codes and afterwards storing the characters; the fourth step of deploying a printing and monitoring service program in the client side, intercepting content data of a printed file in real time, and filtering out the protected sensitive content data. According to the information protection method and system of the sensitive content data, the problem in the prior art that the safety is relatively low existing in the aspect that data leakage is prevented through a safe word stock encryption technology is solved.

Description

technical field [0001] The invention belongs to the technical field of security document protection, and in particular relates to a method and system for protecting sensitive content data information. Background technique [0002] With the development of information technology, all walks of life are increasingly informatized in production and management, and commercial confidential data stored in the form of electronic documents has become an important asset of enterprises. Compared with traditional paper documents, electronic documents have many inherent excellent characteristics, such as: easy to save, save resources, and convenient to spread. Now more and more companies have begun to transfer the preservation of important confidential information from traditional paper documents to electronic documents, such as: corporate strategic plans, engineering design drawings, important list materials, and so on. In particular, with Web2.0 technology-based blogs, microblogs, e-com...

AI Technical Summary

Problems solved by technology

[0006] The present invention provides a method and system for protecting sensitive content data information, which is used to solve the problem of relatively low security in preventing data leaks in the prior art through secure font encryption technology; further, by using the characters in the standard font The multiple mappings of standard codes not only achieve the purpose of encryption and protection of sensitive content data information in computer documents, but also can additionally hide secret information; and thus solve the traceability and tracking technology of sensitive content data information leaked through computer screen photography or printout problem
