A patient signature method and system for electronic medical records

Abstract

The invention discloses a patient signature method and system for an electronic medical record. The method includes: using the long-term private key d A Split into long-term sub-private key d 1 and long-term sub-private key d 2 Two parts, split the temporary private key k into temporary sub-private keys k 1 and temporary sub-private key k 2 Two parts, where the long-term sub-private key d 1 and temporary sub-private key k 1 Generated, kept and kept secret by the server, the long-term sub-private key d 2 and temporary sub-private key k 2 Generated, kept and used confidentially by the patient, and the long-term sub-private key d 2 Encrypted and stored by the patient's face feature value; in the signing process, the server and the patient use their respective long-term sub-private keys and temporary sub-private keys to calculate and exchange intermediate results, and finally the server and patients synthesize the intermediate results , to get the final required SM2 signature value. The invention makes the patient signature process simple and convenient to use. The invention provides safety guarantee for the patient's signature process through face recognition and client / server cooperative signature technology.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a method and a system for signing an electronic medical record patient. Background technique [0002] At present, there are mainly two types of legal and effective patient signature methods on the market. One is the hardware media signature method represented by USBKey and smart card. The compatibility of the software is poor, and the integration of the application system is difficult. These shortcomings lead to a poor user experience when signing the actual signature. In today's increasingly developed Internet applications and more convenient use, the user acceptance of this type of signature method is declining, and the usage scenarios are becoming less and less. [0003] Another type of signature method is the collaborative signature method that has emerged in recent years. When using this method to sign, the user only needs to enter the signature password to co...

AI Technical Summary

Problems solved by technology

For some places with a complex population composition, such as hospital patients, the acceptance of signature passwords varies greatly. Some patients set the signature password to a low-entropy password such as 123456 for easy memory, resulting in signature security. Greatly reduced
