Abstract

The invention provides a data existence authentication system, a data existence authentication method and a data existence verification method. The authentication method comprises the steps of obtaining hash values of target data, and storing the hash values; generating at least one Merkel tree according to the hash values, and storing tree roots of the Merkel tree in block chains of a predetermined block chain network through trading; and generating receipts corresponding to the target data respectively, wherein the receipts comprise corresponding target hash values, corresponding tree roots and paths of the Merkel tree, and trading data storage paths, and the paths comprise the hash values sequentially paired with the target hash values to finally generate the tree roots. According to the data existence authentication system, the data existence authentication method and the data existence verification method, the authentication of the existence of the target data in the trading time can be realized through the trading without depending on an authentication mechanism by utilizing characteristics of the Merkel tree and a characteristic that data in the block chains cannot be rewritten, the trading only needs to store the tree roots in the block chains, and the authentication of batch data can be finished by one-time trading, so that the authentication cost is greatly reduced.

Description

technical field [0001] The application relates to the technical field of data authentication, in particular to a data existence authentication system, authentication method and verification method. Background technique [0002] In real life, in order to prove their legitimate rights, such as writing an article, owning a certain certificate, owning the copyright of certain works, etc., the right holder usually needs to be certified by a third-party certification agency. Therefore, the existing certification mechanism strongly relies on the credit of the certification body. Once the certification body has a credit problem, the rights and interests of the obligee cannot be guaranteed. [0003] At the same time, based on the development of time stamp technology, it provides a solution for the time proof of data. However, the application of time stamp has not been popularized by the existing certification bodies. As a result, certification in third-party certification bodies ofte...
