Embodiment 1

[0037] like figure 1 As shown, a blockchain data management system in this embodiment includes a data creation terminal, a data confirmation terminal and a data management terminal. In this embodiment, the number of data creation terminals, data confirmation terminals and data management terminals is greater than or equal to two.

[0038] The data creation side is used by those who provide elderly care services, such as medical personnel who provide healthcare services. The data creation end is used to create pension data. The data creation end is a computer or a mobile phone, and in this embodiment it is a computer. Pension data includes service items, service recipients and detailed information. Detailed information refers to recorded information on the specific content of a service item; for example, in healthcare services, if it is a medical examination, the detailed information includes the medical examination report, and if it is a disease diagnosis, the detailed info...

Embodiment 2

[0047] The difference between this embodiment and Embodiment 1 is that in this embodiment, the data creation terminal also pre-stores a whitelist, which includes permitted objects and permitted query items; the data management terminal also judges whether the received request confirmation information has Permission, if granted, to retrieve encrypted pension data from all blocks in the blockchain based on the query object and query item.

[0048] For example, the white list includes the license object: D, and the license query item: legal consultation. When lawyer D needs to know the past legal consultation of elderly B before providing legal consultation services to elderly B, he sends a query request through the data creation terminal, specifically query person: D, query object: B, query item: legal consultation. Based on the whitelist, the data management terminal judges that the received request confirmation information is authorized (the permission object is consistent wit...

Embodiment 3

[0050] The difference between this embodiment and Embodiment 1 is that in this embodiment, the pension data also includes service time. In this embodiment, the data confirmation terminal is also used to collect voice information during the service process. A preset statement library is also stored in the data confirmation terminal, and the statement library includes a first key statement, a second key statement and a third key statement. The data confirmation terminal is also used to match the voice information with the sentence library. When the data confirmation terminal matches the first key statement from the statement database, start timing, and when the data confirmation terminal matches the second key statement from the statement database, calculate the interval between the first key statement and the second key statement, and judge Whether the interval time is less than the preset time length, if not less than, the data confirmation end will mark it as an invalid time...

Abstract

The invention relates to the technical field of data management, and particularly discloses a blockchain data management system, which comprises: a data creation end used for creating pension data; adata confirmation end which is used for creating a public key and a private key, receiving the pension data from the data creation end and encrypting the pension data based on the private key; a datamanagement end which is used for obtaining the public key and the encrypted pension data from the data confirmation end, wherein a block chain is locally stored in the data management end, the data management end is further used for packaging the encrypted pension data into a new block and adding the new block to the tail end of the block chain, the data creation end is further used for sending aquery request to the data management end, and the data management end is further used for receiving request confirmation information, acquiring encrypted pension data from the blockchain after receiving the request confirmation information and decrypting the encrypted pension data by using a public key, and the data creation end is also used for sending the decrypted pension data to the data creation end. By adopting the technical scheme of the invention, elderly care data leakage can be prevented.

Description

technical field [0001] The invention relates to the technical field of data management, in particular to a blockchain data management system. Background technique [0002] The traditional management of pension data is realized through a central database. However, the data in the centralized database can be tampered with, so it is difficult to guarantee the authenticity of the pension data, and it is also difficult to trace the responsibility once a problem occurs. In addition, the centralized server has the problem of single point of failure, which can easily lead to data loss and privacy leakage. Some criminals obtain the information in the database to conduct illegal transactions, which is difficult to be detected. Furthermore, whether it is at home or in nursing homes, the elderly usually receive different elderly care services, such as medical care services, emergency rescue services, cultural and educational services, etc.; different elderly care services will be provi...
