Abstract

Medical prescriptions may be produced in electronic form and carry a plurality of encoded, encrypted data sets. The first data set may represent a unique prescription identifier and the second data set a patient identifier such as a PIN: Both data sets are encrypted and printed on the item, for example encoded in a data matrix. The patient may present a printed prescription to a chemist at which point the data matix symbol is canned to retrieve the encrypted data sets. The data set including the unique identifier may be sent to a remote location for decryption and comparison against a stored identifier to verify the prescription as genuine. The second data set may be decrypted and compared locally to verify that the person presenting the prescription is the patient or an authorised representative of the patient. If both data sets are vertified, the chemist maydispense the medicine. Further data sets may include details of the prescription and prescription history, and details of the doctor and the chemist. The latter two can be sent to local health authorities for payment. The doctor can be notified when the prescription is validated and the patient'"'"'s records updated accordingly. Different encryption may be used for the two data sets.

Claims

1. A method of creating a medical prescription, comprising:

creating the prescription in electronic format, the prescription including at least first data set comprising identification information and a second data set, the data sets each being readable independently of the other;

encrypting the second data set;

encoding the first and second data sets on a data carrier; and

printing the prescription with the data carrier having the first and second data sets encoded thereon.

2. A method according to claim 1, wherein the data carrier is a 2-dimensional bar code.

3. A method according to claim 2, wherein the 2-dimensional bar code is a data matrix.

4. A method according to claim 1, wherein the data carrier is a RFID device.

5. A method according to claim 1, wherein the identification information comprising the first data set comprises a unique identifier for the prescription.

6. A method according to claim 1, wherein the second data set comprises identification information.

7. A method according to claim 6, wherein the identification information comprising the second data set comprises a patient identifier.

8. A method according to claim 1, comprising, on receipt of an on-line request, providing the electronic prescription including the first and second data sets over a communication channel for printing.

9. A method according to claim 1, wherein the prescription comprises at least one further data set encrypted on the printed item.

10. A method according to claim 9, wherein the at least one further data set comprise information related to the item prescribed.

11. A method according to claim 1, comprising a further data set encrypted on the prescription and storing information related to the prescribing doctor.

12. A method according to claim 1, comprising a further data set encrypted on the prescription and storing information related to the dispensing chemist.

13. A method according to claim 1, wherein the first and second data sets are part of a value based token having a header including the first data set, a payload including the second and any further data sets, and a security portion.

15. A method according to claim 13, wherein payload comprises a plurality of data sets encrypted using different encryption algorithms.

16. A method according to claim 1, comprising:

scanning the data carrier to read the first and second data items; and

authenticating the prescription by comparing one of the first and second data items with pre-stored data.

17. A method according to claim 16, wherein the first data set comprises a unique identifier and the authenticating step comprises comparing the unique identifier with a stored record and authenticating the item if the unique identifier matches the stored record.

18. A method according to claim 16, wherein the step of authenticating comprises recording the authentication of a unique identifier and rejecting further attempts to authenticate the same unique identifier.

19. A method according to claim 16, wherein the step of authentication is performed at a location remote from the step of scanning the prescription.

20. A method according to claim 16, comprising, after scanning the data carrier, identifying the first and second data sets and processing the first and second data items independently of each other.

21. A method according to claim 13, wherein at least one of the data sets in the payload is protected by a PIN

14. A method according to claim 14, wherein at least one of the second and any further data sets comprises a reference to data stored at a remote location.

22. A system for of creating a medical prescription, comprising:

means for creating the prescription in electronic format, the prescription including at least first data set comprising identification information and a second data set, the data sets each being readable independently of the other;

means for encrypting the second data set;

means for encoding the first and second data sets on a carrier; and

means for printing the prescription with the data carrier having the first and second data sets encoded thereon.

23. Computer software for creating a medical prescription, comprising software for performing the steps of:

creating the prescription in electronic format, the prescription including at least first data set comprising identification information and a second data set, the data sets each being readable independently of the other;

encrypting the second data set; and

encoding the first and second data sets onto a data carrier for printing of the prescription with the data carrier thereon.

24. A method of generating a medical prescription, comprising the steps of:

generating the prescription in electronic form, and encoding thereon a plurality of data sets, including a first data set having a unique prescription identifier, and an encrypted second data set having a patient identifier;

printing the prescription with a data carrier having the first data set and encrypted second data set encoded thereon;

on presentation of the prescription at a pharmacy by a party;

scanning the prescription to decode the data carrier to retrieve the first and second data sets;

comparing the unique identifier of the first data set with pre-stored data;

authenticating the prescription as genuine if there is a match;

decrypting the second data set to recover the patient identifier;

comparing the patient identifier with a patient identifier supplied by the party presenting the prescription; and

if there is a match

authenticating the prescription as acceptable for dispensing to the party wherein the comparison of the unique identifier and the patient identifier are performed independently of each other.

25. A method of creating a medical prescription, comprising:

creating the prescription in electronic format;

including on the prescription a data carrier having encoded thereon a first data set containing unique prescription identifier and an encrypted second data set readable independently of the first data set and including a reference to data stored at a remote location;

storing a record of the unique identifier;

printing the prescription with the encoded data carrier thereon; and

authenticating the prescription by scanning the data carrier to retrieve the unique identifier, comparing the identifier with the stored record, and authenticating the prescription if there is a match.
