Claims
- 1. A method for performing electronic postmarking of data, including user data and location data, the method comprising:
receiving user data from a data acquisition/generation device; receiving location data from a location data acquisition/generation device; merging the user data with the location data to generate merged data; and generating an electronic postmark data structure comprising the merged data and a time/date stamp.
- 2. The method of claim 1, wherein the step of generating the electronic postmark data structure comprises generating a hash value from the merged data.
- 3. The method of claim 1, wherein the stage of generating an electronic postmark data structure includes generating a digital signature for inclusion in the electronic postmark data structure.
- 4. The method of claim 1, wherein location data includes at least one of position, altitude, longitude, latitude, and direction.
- 5. The method of claim 1, wherein the stage of generating the electronic postmark data structure includes forwarding the merged data to an electronic postmarking server.
- 6. The method of claim 1, wherein the stage of generating the electronic postmark data structure includes forwarding the merged data to an embedded electronic postmarking device.
- 7. The method of claim 6, wherein the embedded electronic postmarking device is embedded in the data acquisition/generation device.
- 8. The, method of claim 1, wherein the data acquisition/generation device is one of a digital camera, a digital video recorder, a personal digital assistant, a handheld computer, a laptop computer, and other device capable of generating and storing electronic data.
- 9. The method of claim 1, wherein the location acquisition/generation device is at least one of a GPS sensor, an altitude sensor, a position sensor, a latitude sensor, a longitude sensor, and a direction sensor.
- 10. The method of claim 1, further comprising:
storing the generated electronic postmark data structure in a log file.
- 11. A method for performing electronic postmarking of data, including user data and location data, the method comprising:
receiving user data from a data acquisition/generation device; receiving location data from a location data acquisition/generation device; merging the user data with the location data to generate merged data; and generating an electronic postmark data structure comprising the merged data, a time/date stamp, and a digital signature.
- 12. The method of claim 11, wherein the step of generating the electronic postmark data structure comprises generating a hash value from the merged data.
- 13. The method of claim 11, wherein location data includes at least one of position, altitude, longitude, latitude, and direction.
- 14. The method of claim 11, wherein the stage of generating the electronic postmark data structure includes forwarding the merged data to an electronic postmarking server.
- 15. The method of claim 11, wherein the stage of generating the electronic postmark data structure includes forwarding the merged data to an embedded electronic postmarking device.
- 16. The method of claim 15, wherein the embedded electronic postmarking device is embedded in the data acquisition/generation device.
- 17. The method of claim 11, wherein the data acquisition/generation device is one of a digital camera, a digital video recorder, a personal digital assistant, a handheld computer, a laptop computer, and other device capable of generating and storing electronic data.
- 18. The method of claim 11, where in the location acquisition/generation device is at least one of a GPS sensor, an altitude sensor, a position sensor, a latitude sensor, a longitude sensor, and a direction sensor.
- 19. A system for performing electronic postmarking of data, including user data and location data, the system comprising:
means for receiving user data from a data acquisition/generation device; means for receiving location data from a location data acquisition/generation device; means for merging the user data with the location data to generate merged data; and means for generating an electronic postmark data structure comprising the merged data and a time/date stamp.
- 20. The system of claim 19, wherein means for generating the electronic postmark data structure comprises means for generating a hash value from the merged data.
- 21. The system of claim 19, wherein the means for generating an electronic postmark data structure includes means for generating a digital signature for inclusion in the electronic postmark data structure.
- 22. The system of claim 19, wherein location data includes at least one of position, altitude, longitude, latitude, and direction.
- 23. The system of claim 19, wherein the means for generating the electronic postmark data structure includes means for forwarding the merged data to an electronic postmarking server.
- 24. The system of claim 19, wherein the means for generating the electronic postmark data structure includes means for forwarding the merged data to an embedded electronic postmarking device.
- 25. The system of claim 24, wherein the embedded electronic postmarking device is embedded in the data acquisition/generation device.
- 26. The system of claim 19, wherein the data acquisition/generation device is one of a digital camera, a digital video recorder, a personal digital assistant, a handheld computer, a laptop computer, and other device capable of generating and storing electronic data.
- 27. The system of claim 19, wherein the location acquisition/generation device is at least one of a GPS sensor, an altitude sensor, a position sensor, a latitude sensor, a longitude sensor, and a direction sensor.
