Abstract

The invention relates to the technical field of medical follow-up visits and block chains, in particular to a distributed follow-up visit system based on a block chain and ciphertext retrieval technology. The block chain protocol layer comprises a plurality of block chain consensus nodes used for forming a block chain network and realizing data consensus, and all the block chain consensus nodes equally participate in the consensus process and can generate blocks and store block chains. According to the distributed follow-up visit system based on the block chain and the ciphertext retrieval technology, the system comprises a block chain application layer and a block chain protocol layer, by implementing a block chain technical means and by virtue of the characteristics of decentralization,trust removal and collective maintenance of a block chain, the heterogeneous storage of follow-up visit data can be realized, so that the reliability of the data is ensured, and the data is ensured not to be lost, tampered and non-repudiated through a consensus algorithm; and by implementing database encryption and ciphertext retrieval technical means, original data cannot be identified in a database and can be retrieved without decryption.

Description

technical field [0001] The present invention relates to the field of medical follow-up and block chain technology, in particular to a distributed follow-up system based on block chain and ciphertext retrieval technology. Background technique [0002] Follow-up refers to an observation method in which the hospital regularly understands the post-hospital rehabilitation status of patients who have been in the hospital through communication or other means, such as changes in the patient's condition, whether adverse events have occurred, and mental health status, and guides the patient's recovery. [0003] Follow-up is a necessary part of the hospital's clinical, scientific research, and teaching work. It is also called follow-up. (follow up). To put it simply, after diagnosis and treatment, we continue to follow up and visit patients. [0004] Follow-up visits are mainly conducted through questionnaires, and the recording methods are as follows: manual filling and filing of pa...
