Network information auditing method and system based on ciphertext retrieval

Abstract

The invention discloses a network information auditing method and system based on ciphertext retrieval. An information auditing interface is constructed by use of a power and responsibility separation method, the individual privacy of a user is protected while the efficient network information auditing is realized, and the auditing permission cannot be abused. The principle of the system is to construct an index based on the ciphertext for the information transmitted in a network by the user, and then an auditing condition is constructed by an information auditor so as to audit the information. The specific process is as follows: (1) initializing; (2) index constructing; (3) auditing condition constructing; and (4) information auditing. The system comprises a server-side, a plurality of clients and an auditing side, wherein each client and the auditing side are connected with the server-side through the network. The system has the advantages that the auditing efficiency is high, the unnecessary communication among various departments in the traditional auditing mechanism is avoided, the security is high, the auditor does not intervene in the information except the auditing condition, and the user privacy is protected.

Description

technical field [0001] The invention belongs to the technical field of information security, relates to related technologies of computer software, and in particular relates to a network information review method and system based on ciphertext retrieval. Background technique [0002] With the rapid development of the Internet, more and more users have begun to use network disks or other network storage systems to store personal or corporate data. Network storage can easily realize the functions of user data backup, data sharing among users, and data synchronization. According to the survey, the number of network storage users in my country has exceeded 500 million. [0003] However, frequent network storage failures and vulnerabilities in recent years remind users that there are a series of security problems in existing network storage systems. class security issues. The first is the issue of user privacy protection: data in network storage is vulnerable to internal and ex...

AI Technical Summary

Problems solved by technology

[0003] However, frequent network storage failures and vulnerabilities in recent years remind users that there are a series of security problems in existing network storage systems. class security issues

The first is the issue of user privacy protection: the data in the network storage is vulnerable to internal and external attacks, leading to user data leakage, such as the Hollywood pornography incident in iCloud, the file leakage incident in Google Doc, etc.

The second is the issue of content review: due to the convenience of storing and sharing data in network storage, many illegal data are often spread through network storage, and relevant departments need to conduct effective information review of data in network storage

Secondly, the communication of this kind of review is often inefficient and needs to go through layers of approval, and the data transmitted in network storage is very time-sensitive, which easily leads to the loss of review opportunities

[0005] To sum up, there is currently a lack of an efficient and secure information review mechanism for information stored on the network
