Abstract

The invention discloses a privacy information management method and system based on block chain and IPFS technology, and the method comprises the steps: obtaining an access request sent by a user, the access request comprising a user ID and an access object; verifying whether the user has an access right or not by querying a block chain account book; and if the access authority exists, retrieving a hash record corresponding to the access object from the block chain account book, and accessing the access object stored in the IPFS according to the hash record. Therefore, an independent privacy information management mechanism is established to realize the storage, access and authority management of the privacy information of the block chain network and the sensitive information supervision of the supervised block chain network, so that not only can the storage pressure brought to the block chain node be avoided, but also the comprehensive supervision of the multi-user and multi-type privacy information can be realized.

Description

technical field [0001] The present invention relates to block chain technology, in particular to a privacy information management method and system based on block chain and IPFS technology. Background technique [0002] Trusted file storage is a new type of architecture in the current Internet system. Traditional file storage cannot guarantee the credibility of file storage. When an enterprise user initiates a file storage request to the enterprise, the enterprise will store the enterprise user's file on the server, and then retrieve the file from the server and return it when the enterprise user needs it. Since the files are only stored on an enterprise server, the credibility of the files cannot be guaranteed, and the files may be modified. Files can be stored on the blockchain by using the blockchain, so that the credibility of the files can be guaranteed, so that the files stored by the user become the user's private information, but it also introduces new problems. The...
