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.
