Blockchain automatic registration device for documents such as official daily reports and medical records

Abstract

We provide a blockchain automatic registration device for documents such as official daily reports and medical records that ensures the authenticity of business records, simplifies certification, and prevents tampering. [Solution] The system is equipped with an input means for acquiring electronic records entered or edited by users from a personal computer or tablet terminal, a communication means for sending or transferring the electronic records to a central information processing device, a processing means for hashing and digitally signing the electronic records, and a registration means for automatically registering the processing results obtained by the processing means in a blockchain, and is configured to automatically execute based on the electronic records.

Description

[Technical Field]

[0001] This invention relates to a recording device that stores business records such as official daily reports and medical charts and simultaneously registers them in a blockchain. [Background technology]

[0002] Traditionally, business records have mainly been stored locally or manually in the cloud, but there is always the risk of records being tampered with or deleted, and there are limitations to their admissibility as evidence.

[0003] To ensure the authenticity of business records, simplify certification, and prevent falsification.

[0004] In this invention, when business records entered and edited from a business record terminal (PC, tablet, etc.) are "save" or "end" operations are performed, a hash value is generated for the recorded data, a signature is applied, and the data is simultaneously registered and saved in the blockchain and the host computer. Furthermore, a digital certificate with a QR code is automatically generated immediately, making it possible to verify the contents of the record. Effects of the invention

[0005] · The authenticity of registration records is ensured. · Certificates are generated instantly, ensuring their reliability as evidence. The entire process of saving, registering and certifying can be completed with a single touch, reducing the workload on-site.

[0006] Example 1: After a doctor enters medical records, he or she presses the "Save Medical Record" button. → The records are automatically registered in the hospital's host computer and on the blockchain, and a certificate is issued. Example 2: A city hall employee enters the activity record of a resident visit and clicks "End." → This is also registered on the blockchain and can be submitted as a certificate to the resident or their superior at a later date.

Claims

[Claim 1] A blockchain automatic registration device configured to send electronic records such as official daily reports, medical charts, and business reports entered or edited using a business record terminal to a host computer when the "save" or "end" operation is triggered, and at the same time automatically register the hashed and signed data in the blockchain.
