Abstract

The invention relates to a data reading method and device, a data authorization method and device and a storage medium. The data reading method comprises the steps of receiving an identity identifiersent by a client and a reading request for requesting to access target data on a block chain; determining whether the identity identifier belongs to a member identifier of a legal institution authorized to access the target data; and if the identity identifier is a member identifier belonging to a legal institution authorized to access the target data, obtaining decrypted target data according tociphertext data encrypted based on a second key and obtained from a blockchain and a first key obtained by encrypting the second key. Therefore, as long as the reading request of the member identifierof the legal mechanism with authorized access can be responded, the data reading is more convenient and reasonable.

Description

technical field [0001] The present disclosure relates to the technical field of blockchain, and in particular, to a data reading method and device, a data authorization method and device, and a storage medium. Background technique [0002] In the supply chain business, operations such as writing, querying, or deleting are performed on business data. These operations on data involve the data authorizer and the data reader who wants to query the data. When the data reader wants to execute the query, it needs the authorization of the data authorizer. After the authorization, the data reader can complete the reading of the data. Since most of the data is stored after being encrypted, the corresponding key is required to access the data when reading, and the current authorization method for encrypted data is limited, only a specific private key Only authorized data can be accessed, which makes the actual application effect not good. Contents of the invention [0003] The disc...
