Embodiment Construction

[0033] In order to describe the present invention more specifically, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] The present invention is based on the privacy protection method of blockchain technology, and the specific implementation process is as follows:

[0035] Firstly, the private data is encapsulated into independent blocks with consistent structure, such as figure 1 As shown, the block header and the block body form an independent block. Among them, the block header is the basic information column of an independent block, which internally encapsulates basic information such as the block version number, the address of the previous block, timestamp, the current block hash value, random number, and the address of the next block; The block body encapsulates the private data and its change records, and is organized in the form of a Merkle tree. The data c...

Abstract

The invention discloses a privacy protection method based on a block chain technology. The privacy protection method based on a block chain technology is characterized in that a block chain is formed by means of head-tail-connection of a large amount of blocks with similar organization structure; and each independent block can encapsulate privacy data with a time stamp, and can complete distributed networking propagation and a consensus algorithm task of distributed nodes at the same time, thus realizing efficient normal form organization management of the privacy data. Besides, the privacy protection method based on a block chain technology coordinatively uses an asymmetric encryption algorithm-Elgamal in the block chain, wherein a public key password and a private key password are respectively corresponding to encryption and decryption process of data; and the theoretical quantity of the private keys is very great, so that the possibility that the privacy data is stolen by traversing the whole private key space does not exist and then the safety of the privacy data can be guaranteed in cryptography. The complete organization and operating mechanism of the block chain enables the privacy protection method based on a block chain technology to have wide application prospect in the privacy protection field.

Description

technical field [0001] The invention belongs to the technical field of Internet privacy protection, and in particular relates to a privacy protection method based on block chain technology. Background technique [0002] A new data organization structure and calculation method called blockchain is booming with the invention of digital encryption currency. Blockchain has many advantages such as distributed, decentralized, data collective maintenance and sharing, programmable, high security and reliability. In addition to the field of digital encryption currency, blockchain technology is also particularly suitable for data encryption storage, financial transactions, IoT and other fields. Some scholars even predict that blockchain technology will be the cornerstone of the next-generation Internet and will lead the development of the Internet in the future. [0003] At present, blockchain technology has attracted great attention from many fields represented by finance and the I...
