As a medical document established and stored digitally, electronic medical records conform to the category of "data message" defined in this Law. Therefore, there is no legal obstacle to the use of electronic signatures in electronic medical records.

However, it should be pointed out that in this article, an electronic signature must be "contained in and attached to" a data message. That is to say, as a signed data message, an independent identifiable data entity must be clearly formed, and the electronic signature data needs to be included in this independent entity.

In this way, from the point of view of technical realization, the medical record is directly stored in the database through logical association (primary key, index code, etc.), and then the legality of the electronic signature is stored elsewhere. ) was excluded.

Article 13 of the Electronic Medical Record Law:

The conditions for determining a reliable electronic signature are as follows: "An electronic signature that meets the following conditions is a reliable electronic signature:

(a) Electronic signature data dedicated to electronic signatures;

(2) When signing, the electronic signature production data is only controlled by the electronic signer;

(3) Any changes to the electronic signature after signature can be found;

(4) Any changes to the content and form of the data message after signature can be found. The parties can also choose to use electronic signatures that meet their agreed reliable conditions. "

Technically, this definition, especially the last one that allows the autonomy of the parties, provides legal support for us to adopt a more economical electronic signature scheme.
