A method and system for manage confidential documents

Abstract

The invention discloses a confidential document management method and a system. The method comprises the following steps: creating a confidential document; Using the public key of the secondary unit to encrypt the confidential file to obtain the first encrypted file; encrypting The first encrypted file by using the private key of the first level unit to obtain the second encrypted file, and encrypting the reader list set by the first level unit by using the private key of the first level unit. Adopting A block chain consensus mechanism algorithm to respectively create a block of confidential document and a block of reader list for the second encrypted file and the encrypted reader list; and adopting the block chain consensus mechanism algorithm to respectively create a block of confidential document and a block of reader list for the second encrypted file and the encrypted reader list. Broadcasting the newly created block of confidential documents and the block of reader list to the network, and notifying the relevant secondary units. The invention effectively improves the generation speed of the block, can realize the anti-tampering and traceability of the confidential documents,can realize the unified management of the confidential documents, has high safety, flexible algorithm, simple management and wide application range, and can be widely applied in the Internet industry.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and system for managing secret-related files. Background technique [0002] In some units, the transfer of some confidential documents is often involved. The traditional approach is to set up a special secrecy agency for the management of confidential documents and communication of confidential information, and a full-time secrecy officer for management. Due to concerns about document leaks, most documents are delivered in paper form, and relevant personnel need to go to a special confidential room to read them when they want to read them. With the development of Internet technology and mobile terminal technology, these relevant units have begun to try to build a confidential private network for the transmission and reading of confidential documents. Due to concerns about insufficient security levels and protection measures, different departments of the same unit,...

AI Technical Summary

Problems solved by technology

[0003] 1. There are a large number of secret-related documents, which are scattered and stored in different locations, and are easily affected by technical or human factors, resulting in the leakage of documents. If ordinary Internet file management methods are adopted, it is easy to cause document leakage

[0004] 2. Confidentiality-related documents have different levels of confidentiality, existing management methods are not uniform, and files of different confidentiality levels are stored in a mixed manner

In addition, most confidential documents have a confidentiality period. Due to management and technical constraints, many documents cannot be decrypted in time after the confidentiality period expires.

[0005] 3. The secret-related file management system that relies on the existing confidential private network operation is prone to loopholes in authority control. Hackers and spies will use technical means to elevate authority, illegally access and read files beyond the scope of normal authority

[0006] 4. The fine-grained management of confidential documents is not enough, and it is impossible to accurately control the number of times the documents are read

[0007] 5. The vast majority of important confidential documents dare not go online, making it inconvenient to check

If confidential files are stored centrally, it will bring serious consequences in the event of intrusion or physical damage

[0008] 6. It is impossible to fundamentally solve the problem of secret agents, malicious personnel, hackers, etc. sneaking into the secret room to take pictures and steal files

[0009] Generally speaking, in the current technology, the management of confidential documents has problems such as inability to manage them in a unified manner, complex and cumbersome management methods, and poor security.
