Abstract

A method and apparatus for securely transferring medical information is provided, which included storing information relating to a medical prescription item on a smart card using an encryption method that provides independent verification as to the source of the information, verifying the source of the information by the provider of the medical prescription item and modifying the stored information relating to the medical prescription item when the prescription is filled, and storing the modified information on the smart card using an encryption method that provides independent verification of the source of the modified information.

Claims

1. A method for securely transferring medical information comprising:

storing information relating to a medical prescription item on a smart card, using an encryption method which provides independent verification as to the source of the information;

verifying the source of the information by the provider of the medical prescription item;

modifying the stored information relating to the medical prescription item when the prescription is filled; and

storing the modified information on the smart card using an encryption method that provides independent verification of the source of the modified information.

2. A method as set forth in claim 1 wherein additional medical information is stored on a portion of the smart card in an unencrypted form.

3. A method as set forth in claim 2 wherein the information stored in unencrypted form comprises information related to medical history information.

4. A method as set forth in claim 1 wherein the encryption method is a private key/public key encryption method and the medical prescription item is a prescription entered into the smart card by a medical practitioner using the medical practitioner'"'"'s private encryption key.
