The digital fingerprint of XML Electronic Medical Records based on HMAC-SHA256 Algorithm

In order to protect the integrity and consistency of XML Electronic Medical Records in the network transmission, the paper used the HMAC-SHA256 Algorithm to study the "digital fingerprint" and the authentication of the whole XML Electronic Medical Records. In the paper, the result compared the three groups of experimental data illustrated that the values of the HASH would change if the PIN or XML Electronic Medical Records became a different value. So it could strongly proved that the research using the Algorithm could help to identify the integrity and consistency of the XML Electronic Medical Records before and after the Network transmission.
