Method and apparatus for secure wireless point of sale transactions

1. A method of conducting a secure wireless sales transaction, comprising:

wirelessly transmitting pseudo transaction data from a first wireless transaction instrument with a transmitter of the first wireless transaction instrument, wherein the pseudo transaction data is transmitted independently from actual transaction data;

wirelessly receiving combined data at the first wireless transaction instrument, with a receiver of the first wireless transaction instrument, after wirelessly transmitting the pseudo transaction data, wherein the combined data comprises the pseudo transaction data together with the actual transaction data and the combined data is from a second wireless transaction instrument of a co-transacting party;

processing the combined data with a processor of the first wireless transaction instrument to remove the pseudo transaction data from the combined data to separate the actual transaction data from the pseudo transaction data; and

performing a transaction with the co-transacting party based on the actual transaction data.

2. The method of claim 1 , wherein transmitting the pseudo transaction data comprises transmitting false transaction data configured to mimic a protocol of the actual transaction data.

3. The method of claim 1 , wherein processing the combined data comprises processing a first input of the pseudo transaction data and a second input of the combined data to remove the pseudo transaction data.

4. The method of claim 1 , wherein wirelessly transmitting the pseudo transaction data comprises transmitting a watermark.

5. The method of claim 1 , wherein processing the combined data comprises identifying a transmission from the second wireless transaction instrument of the co-transacting party and the actual transaction data.

6. The method of claim 1 , wherein wirelessly transmitting the pseudo transaction data comprises transmitting false transaction data via a near field communication network.

7. The method of claim 1 , wherein wirelessly receiving the combined data comprises receiving the pseudo transaction data from a plurality of point of sale devices and receiving the actual transaction data from the second wireless transaction instrument of the co-transacting party.

8. The method of claim 7 , wherein processing the combined data comprises utilizing direct inputs of the pseudo transaction data from the plurality of point of sale devices to remove the pseudo transaction data from the actual transaction data.

9. The method of claim 7 , wherein processing the combined data includes utilizing orthogonal code division separation to isolate the actual transaction data of the co-transacting party.

10. The method of claim 7 , wherein processing the combined data includes processing a locally stored version of the pseudo transaction data to identify the pseudo transaction data from the plurality of point of sale devices.

11. The method of claim 7 , wherein the pseudo transaction data from the plurality of point of sale devices comprises false transaction data that is the same for each of the point of sale devices.

12. The method of claim 7 , wherein processing the combined data includes utilizing frequency separation to isolate the actual transaction data of the co-transacting party.

13. The method of claim 7 , wherein processing the combined data includes utilizing time separation to isolate the actual transaction data of the co-transacting party.

14. A method of masking transaction data for a secure wireless transaction, comprising:

wirelessly transmitting pseudo transaction data from a first wireless transaction instrument with a transmitter of the first wireless transaction instrument, wherein the pseudo transaction data is transmitted independently from actual transaction data, and wherein the pseudo transaction data includes false transaction data; and

processing, with a processor of the first wireless transaction instrument, combined data including the pseudo transaction data and the actual transaction data to extract the actual transaction data from the combined data after wirelessly transmitting the pseudo transaction data.

15. The method of claim 14 , wherein the false transaction data is configured to mimic a protocol of the actual transaction data.

16. The method of claim 14 , wherein processing the combined data comprises processing a first input of the pseudo transaction data directly from a generator of the pseudo transaction data and a second input of the combined data to remove the pseudo transaction data.

17. The method of claim 14 , comprising receiving the combined data from a wireless network and communicating the combined data to a processor.

18. The method of claim 14 , wherein processing the combined data comprises receiving the combined data at a processor and identifying a transmission from a second wireless transaction instrument of a co-transacting party and the actual transaction data.

19. The method of claim 17 , wherein processing the combined data comprises receiving the pseudo transaction data from a plurality of point of sale devices and receiving the actual transaction data from a second wireless transaction instrument of a co-transacting party.

20. The method of claim 19 , comprising wirelessly transmitting the pseudo transaction data from the plurality of point of sale devices, wherein transmitters of each of the plurality of point of sale devices are isolated from one another.

21. The method of claim 17 , wherein wirelessly transmitting the pseudo transaction data comprises transmitting a watermark to enable a tracing of a third party attempting to use the pseudo transaction data.

22. The method of claim 17 , wherein wirelessly transmitting the pseudo transaction data comprises transmitting the pseudo transaction data via a near field communication network.
