Problems solved by technology

However, so far, no protocol or algorithm has been proposed to effectively implement these security requirements of the electronic reporting scheme. How to construct an electronic reporting scheme with the above characteristics is an unresolved problem. Designing an efficient and reliable reporting mechanism using cryptographic technology is One of the current research hotspots

Abstract

The invention discloses an anonymous reporting method based on a block chain technology, and the method comprises the steps: generating public keys and private keys of all reporters and a law enforcement agency, and generating a block chain public key address and a corresponding private key of the law enforcement agency; processing the reporting information of the reporter based on a ring signcryption algorithm, generating a signcryption ciphertext, and sending the signcryption ciphertext to a law enforcement agency; the law enforcement agency carries out resolving after receiving the signcryption ciphertext, obtains and verifies the report information, and receives the report information if the verification is passed; and if the report information is valid, the law enforcement agency transfers the bonus to the public key address of the reporter on the block chain based on an anonymous reward algorithm, and the reporter obtains the bonus based on the private key. According to the method, confidentiality, non-repudiation and privacy protection of the identity of a reporter are provided for reporting information transmission, enough safety service is provided for the reporter, and crimes are safely reported.

Description

technical field [0001] The invention belongs to the field of cyberspace security, and in particular relates to an anonymous reporting method based on block chain technology. Background technique [0002] In daily life, acts of fraud, crime, and endangering public interests frequently occur. In order to punish perpetrators, law enforcement agencies use many methods to collect criminal evidence, among which reporting is a very useful method. Reporting by those with clues or evidence can prevent or expose these illegal activities. However, in daily life, whistleblowers are often retaliated by criminals because their identities are exposed. [0003] At present, the network has penetrated into every aspect of people's life, and it is very meaningful to build an effective electronic reporting scheme in the network environment. A sound reporting mechanism can not only improve the efficiency of reporting, but also protect whistleblowers from retaliation. Therefore, a good reporti...
