Electronic medical record patient signature method and system

Abstract

The invention discloses an electronic medical record patient signature method and system. The method comprises the following steps: splitting the long-term private key dA into two parts, namely, a long-term sub-private key d1 and a long-term sub-private key d2; splitting the temporary private key k into a temporary sub-private key k1 and a temporary sub-private key k2, wherein the long-term sub-private key d1 and the temporary sub-private key k1 are generated, stored and secretly used by the server side, the long-term sub-private key d2 and the temporary sub-private key k2 are generated, stored and secretly used by the patient side, and the long-term sub-private key d2 is encrypted and stored through a patient face feature value; and, in the signature process, the server side and the patient side respectively use respective long-term sub-private key and temporary sub-private key to calculate and exchange intermediate results, and finally the server side and the patient side synthesizethe intermediate results to obtain a final required SM2 signature value. The patient signature process is simple, and the use is convenient. According to the invention, security assurance is providedfor the patient signature process through the face recognition and client / server collaborative signature technology.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a patient signature method and system for an electronic medical record. Background technique [0002] At present, there are 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. Poor compatibility, and application system integration difficulties, etc., these shortcomings lead to poor user experience in the actual signing. Today, with more and more 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, users only need to enter the signature password to complete the signature operation, and there is no bur...

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
