Abstract

The invention discloses a data preservation method and system based on a block chain. The method comprises the following steps: a specific user terminal sending a to-be-preserved target file to a center server terminal, the center server terminal performing a data preservation operation on source data of a target file to acquire a preserved data fingerprint of the source data; the center server terminal storing a target file ID corresponding to the target file and the source data, sending the target file ID corresponding to the target file and the preserved data fingerprint to other user terminal and the specific user terminal connected with the block chain; the other user terminal and the specific user terminal connected with the block chain receiving and storing the target file ID corresponding to the target file and the preserved data fingerprint. Each user terminal connected with the block chain only saves the fingerprint information and does not save the source data, and the center server terminal only saves the source data and does not save the fingerprint information; therefore, the source data and the fingerprint are separated, and security of the preserved data is guaranteed.
