The method can include receiving, by a blockchain node, an authentication transaction submitted by a privacy computing platform, where the authentication transaction queries whether a data user has obtained authorization of target data possessed by a data owner, and in response to determining that the data user has obtained authorization of the target data, executing, by the blockchain node, a smart contract invoked by the authentication transaction to provide an authorization token to the privacy computing platform that instructs the privacy computing platform to obtain the target data, and send a computational result of one or more predetermined computational operations based on the target data to the data user."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Blockchain-based data authorization method and apparatus","description":"One or more implementations of the present specification provide a blockchain-based data authorization method and apparatus.
