Embodiment 2

[0068] Embodiment 2: Step 1: Blockchain multi-node P2P network construction. The management node is used to receive the important data Data of the advertising media, and each management node needs to pass the full node verification to run in the blockchain network. Each node maintains and records the important data Data of advertising media, and participates in the consensus service at the same time.

[0069] Step 2: User registration of the advertising media application. Advertising media application user registration needs to be registered and registered in the blockchain network at the same time, and the user key sessionKey generated by the blockchain network in the form of JWT (Java Web Token) is returned to the application.

[0070] Step 3: User uses a symmetric encryption algorithm to encrypt the privacy data of the advertising media business, such as AES, assuming that the encryption function is E, the plaintext is P, the key is K, and the encryption calculation method...

Abstract

The invention discloses an advertisement media service data credible storage system based on a block chain, which can more comprehensively protect the safety of advertisement media service data. The method comprises the following steps: firstly, selectively encrypting advertisement media business privacy data through a symmetric encryption algorithm; secondly, storing the data in the block chain,permanently storing important data in the chain, meanwhile, ensuring the tamper resistance of the advertisement media service data stored in the chain by combining an elliptic curve algorithm of the block chain, and meanwhile, ensuring the privacy of the advertisement media service privacy data. The method can effectively prevent the advertisement media business data from being tampered, has the advantage of high security, and provides a credible evidence storage method for the advertisement media business data.

Description

technical field [0001] The present invention relates to the application field of block chain technology, in particular to a block chain-based trusted certificate storage system for advertising media business data. Background technique [0002] With the development of advertising media technology and network technology, illegal tampering, deletion, and replacement of advertising media content have occurred. Mainly by attacking the front-end advertising media system of the operator, illegally tampering or replacing the advertising media content sent to end users, and disseminating illegal information. End users cannot accurately judge the true value of information and are easily harassed by malicious advertising media content. [0003] With the continuous development of Internet technology, blockchain technology is gradually becoming mature. Blockchain, with its distributed ledger structure, de-intermediation trust mechanism and non-tamperable technical characteristics, can p...
