Abstract

The invention discloses a block chain-based data storage method with third-party authentication. The method comprises the steps that a data storage agent receives a service request data package sent by a user, wherein the data package contains a user ID and to-be-stored data; the data storage agent packages the user ID and the to-be-stored data in an authentication request data package, and sends the authentication request data package to a third-party authentication mechanism; the third-party authentication mechanism performs credible signing on the user ID and the to-be-stored data, and sends a credible signature to the data storage agent; and the data storage agent stores the user ID, the to-be-stored data and the credible signature of the third-party authentication mechanism in a block chain. The method has the following advantages: two entities including the data storage agent and the third-party authentication mechanism are introduced; the data storage agent performs representation and storage on the data by a unified data structure; and the third-party authentication mechanism performs credible signing on all the data, so that the credibility, efficiency, universality and portability of data storage are improved.

Description

technical field

[0001] The invention relates to the field of network information security, in particular to a blockchain-based data storage method with third-party authentication. Background technique

[0002] At present, there are already some use cases of using blockchain to store data, such as recording the copyright information of music works, recording the circulation information of diamonds, etc. These use cases usually adopt a transaction-driven data storage method, that is, initiate a virtual currency (such as Bitcoin) transaction, embed the data to be stored into the transaction data structure, and store it in the blockchain in a distributed manner.

[0003] The above method uses the distributed characteristics of the blockchain to improve the reliability of data storage, and uses the non-modifiable characteristics of the blockchain to ensure that the data is not tampered with. However, the disadvantages of this method are also obvious: (1) All parties that store d...
