ABSTRACT:
A method for securing patient medical information for communication over a potentially vulnerable system includes separating patient's medical file into a demographics layer and a data layer, separately encrypting the demographic layer and data layer using different encryption keys, and providing servers in a communication and processing system with a decryption key for the layer processed by such server. Medical file data may be separated into more than two layers. Users accessing the system are authenticated using standard techniques. By separately encrypting different parts of a patient medical record, processing and communication of patient medical files by intermediary servers is enabled without risking disclosure of sensitive patient information if such servers are compromised.
