Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below according to specific embodiments and accompanying drawings, but the protection scope of the present invention is not limited to the following embodiments.

[0029] The workflow of the anonymous information feedback system of the present invention is as figure 1 As shown, the specific workflow is:

[0030] (1) System global initialization

[0031] GlobalSetup(λ)→GP: System initialization, with a security parameter λ as input, and output the global public parameter GP of the system.

[0032] (2) Initialization of the attribute authorization center

[0033] AASetup(GP)→(ASK, APK): The attribute authorization center is initialized. This algorithm takes the global public parameter GP as input to generate the attribute public-private key pair ASK and APK of the attribute authorization center. The attribute authoriz...

Abstract

The invention belongs to the technical field of block chains, and particularly relates to an anonymous information feedback system based on an attribute signature and a block chain. The anonymous information feedback system comprises an information feedback person (user), an information viewer (user), an attribute authorization center, an attribute authorization center server, an information feedback user side and a feedback information chain network. According to the method, the attribute signature based on decentration is improved, a revocable attribute signature algorithm suitable for decentration is provided, the algorithm is combined with the block chain, and a user privacy protection service is provided in an information feedback block chain system; the problems that in a current information feedback system, user identity privacy is leaked, and information is maliciously tampered and deleted after being issued are solved, and fairness, legality and safety of social information circulation and social supervision are promoted.

Description

technical field [0001] The invention belongs to the technical field of blockchain, and in particular relates to an anonymous information feedback system. Background technique [0002] Information feedback is the process in which the information receiver reacts to the information transmitted by the sender and returns this response to the sender. As one of the core concepts of communication studies, the essence of information feedback is to enable information dissemination to have a two-way communication process. Information feedback is therefore widely used in various social life scenarios, such as feedback on people's livelihood, internal enterprise feedback, user feedback, etc. As an important way to understand the wishes of the masses and promote scientific decision-making, information feedback can play a role in promoting the efficient operation of governments, enterprises and other organizations. [0003] The advent of the Internet era has triggered a "tool revolution" ...
