The main solutions to the problem are as follows:
1) Comprehensive introduction of digital certificates issued by the legitimate third-party electronic certification services, the construction of digital certificates in the hospital acceptance point system for the issuance of digital certificates for the hospital's health care personnel;
2) Through the digital signature verification service system to effectively solve the authenticity of the identity of the user of the electronic medical record system and reliability issues and to achieve reliable digital signatures for key business data;
3) Realize digital signatures and visualization of digital signatures for electronic medical record data messages through the electronic signature system, effectively solving the problem of data security and responsibility attribution for medical data messages in the electronic medical record system;
4) Deploy authoritative and trustworthy time source equipment in the hospital, and realize time-stamp authentication for medical data messages based on the time-stamp service system to ensure that electronic data messages can be authenticated by time-stamps and certified by the time-stamp service system. timestamp authentication to ensure the legitimacy and validity of electronic data.
