Problems solved by technology

[0003] Entity alignment in the prior art generally involves multiple similarity calculations between the data to be processed and the standard data, or converts the data into a vector matrix and then performs similarity calculations, which requires a large amount of computation and low efficiency
For example, the Chinese invention with publication number CN110928894A discloses an entity alignment method, which is to calculate the similarity between the data to be processed and each standard data in the candidate data set, and select the target standard data as the alignment result based on the similarity value ,low efficiency

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...

Abstract

The invention relates to an entity alignment method and system based on a block chain, a storage medium and electronic equipment, and the method comprises the steps of receiving own information of an entity body input by a user, generating one or more first IDs based on an ID generation algorithm in the block chain, and storing the one or more first IDs in the block chain; receiving entity main body data of each data holder input by a user, and generating a corresponding second ID based on the ID generation algorithm in the block chain; and comparing whether the plurality of input second IDs are the same or not, and if the plurality of input second IDs are the same, judging that the plurality of entity main bodies corresponding to the plurality of second IDs are the same entity. According to the entity alignment scheme, the identities of different IDs held by all parties are aligned through the IDs issued by the entity main body, alignment of entity information is achieved, and due to the safety of the block chain technology, it is guaranteed that privacy or sensitive information is not leaked in the whole process.

Description

technical field [0001] The present invention relates to the technical field of natural language processing, in particular to a blockchain-based entity alignment method and system, a storage medium, and electronic equipment. Background technique [0002] Natural language processing (NLP) is an important direction in the field of computer science and artificial intelligence. In natural language processing, entities can be simply understood as names of people, places, institutions, etc. In the context of big data technology, multiple data holders may obtain asymmetric information. For the main information (such as personal information, corporate information), some organizations have historical names or ids, while others may only have the latest data. In the case of asymmetric data held by different data holders, even if it is the same subject in fact, the relevant data cannot be merged under the condition that the data is not sure that the data is the same subject, that is, ef...
