Embodiment 1
[0047] see figure 1 Specifically, the blockchain-based entity alignment method provided in this embodiment includes the following steps:
[0048] S10, the entity subject enters its own information on the chain, and generates one or more (multiple in this article refer to Two or more) the first ID, and stored in the block chain.
[0049] In this step, the self-owned information entered by the entity subject on the chain refers to the identity information of the entity subject, and does not include other information related to the entity subject, so as to ensure the privacy and security of the data. Identity information can contain a variety of information. For example, for natural person entities, identity information can include former name, current name, date of birth, ID number, passport number, social security card number, Hong Kong and Macau passport number, etc. For another example, for a company entity, the identity information may include company name (formerly used a...
Embodiment 2
[0068] see figure 2 Compared with Embodiment 1, the block chain-based entity alignment method provided in this embodiment mainly differs in steps S10 and S30, which are replaced by steps S10' and S30' respectively.
[0069] Specifically, S10', the entity subject enters its own information on the chain, and based on the ID algorithm in the blockchain, generates one or more first IDs, and establishes the association between the first ID and the user's blockchain address , and stored in the blockchain.
[0070] The blockchain assigns an address to each physical subject, and this address is unique. For example, in the example in Example 1, after establishing an association relationship between each ID and the blockchain address, the following table can be obtained:
[0071]
[0072]
[0073] Specifically, S30', compare the second IDs of the data holders to be aligned, if the second IDs are the same, or if the second IDs are different but the associated blockchain addresse...
Embodiment 3
[0078] Compared with Embodiment 1 or 2, the block chain-based entity alignment method provided in this embodiment also includes the step of: receiving the digital signature of the entity subject input by the user on the block chain to the authorization information, so that the data holds The authorized party provides the authorized data to the data user for use within the scope of authorization.
[0079] That is to say, after the data holder enters the ID it has, it will receive the public key fed back by the blockchain (or also include the associated blockchain address), and based on the public key, the authorization can be decrypted. information.
[0080] That is to say, when a data user needs to use the information of an entity subject, the entity subject authorizes the legal use of the information through a digital signature on the blockchain.
[0081] It should be noted that the information (information other than identity information) of the entity subject that the data...
