Abstract

An electronic data sharing device configured to exchange a first tag with a corresponding tag from a further electronic data sharing device, wherein the first and second tags provide information that enables respective users of the electronic data sharing devices to share information via a server enabled internet-connected software system associated with the electronic data sharing devices, wherein the electronic data sharing device is either configured with a pre-shared key or is able to encrypt a session key, wherein the pre-shared key or session key are used to generate tags to ensure that: the electronic data sharing device and tags can only be made use of by the server.

Claims

1. An electronic data sharing device configured to exchange a first tag with a corresponding tag from a further electronic data sharing device,

wherein the first and second tags provide information that enables respective users of the electronic data sharing devices to share information via a server enabled internet-connected software system associated with the electronic data sharing devices, and

wherein the electronic data sharing device is either configured with a pre-shared key or is able to encrypt a session key, wherein the pre-shared key or session key are used to generate tags to ensure that

the electronic data sharing device and tags can only be made use of by the server.

2. The electronic data sharing device of claim 1, wherein the electronic data sharing device is a personal portable electronic device or static or mobile electronic device offering a public service or used for a purpose other than as a personal device.

4. The electronic data sharing device of claim 1, wherein the further electronic data sharing device is a personal portable electronic device or a static or mobile electronic device offering a public service or used for a purpose other than as a personal device.

6. The electronic data sharing device of claim 1 further configured to generate the tags using a cryptographically-secure pseudo-random number generator (CSPRNG).

7. The electronic data sharing device of claim 6, wherein the CSPRNG is implemented in a hardware or software XTEA encryption module, or AES encryption module that is configured in counter mode.

8. The electronic data sharing device of claim 6, wherein the key to the CSPRNG is encrypted, optionally using any form of public key encryption, including RSA public key encryption.

10. The electronic data sharing device of claim 1, wherein the electronic data sharing device is configured to hold a public key that corresponds with a private key held by the software system.

11. The electronic data sharing device of claim 1 further configured to exchange the tags using radio communication.

12. The electronic data sharing device of claim 1, wherein the tags are used to construct statistical information based upon user activity, construct individual or group profiles based upon user activity, construct social-graphs based upon user activity, construct other graphs based upon user activity, construct time-lines based upon user activity or construct maps based upon user activity.

13. The electronic data sharing device of claim 1, wherein the software system includes one or more of personal computers, connections to the internet and remotely located computer servers.

14. A method of sharing data using an electronic data sharing device, the method comprising:

exchanging a first tag with a corresponding tag from a further electronic data sharing device, wherein the first and second tags provide information that enables respective users of the electronic data sharing devices to share information via a server enabled internet-connected software system associated with the electronic data sharing devices; and

using a pre-shared key or encrypting a session key, wherein the pre-shared key or session key are used to generate tags, to ensure that the electronic data sharing device and tags can only be made use of by the server.

15. The method of claim 14, wherein the electronic data sharing device is a personal portable electronic device or a static or mobile electronic device offering a public service or used for a purpose other than as a personal device.

17. The method of claim 14, wherein the further electronic data sharing device is a personal portable electronic device or a static or mobile electronic device offering a public service or used for a purpose other than as a personal device.

19. The method of claim 14 further comprising the step of generating the tags using a cryptographically-secure pseudo-random number generator (CSPRNG).

20. The method of claim 19, wherein the CSPRNG is implemented in a hardware or software XTEA encryption module, or AES encryption module that is configured in counter mode.

21. The method of claim 19 further comprising the step of encrypting the key to the CSPRNG.

22. The method of claim 21 further comprising the step of encrypting the key to the CSPRNG using any form of public key encryption, including RSA public key encryption.

23. The method of claim 14, wherein the electronic data sharing device is configured to hold a public key that corresponds with a private key held by the software system.

24. The method of claim 14 further comprising the step of exchanging the tags using radio communication.

25. The method of claim 14, wherein the tags are used to construct statistical information based upon user activity, construct individual or group profiles based upon user activity, construct social-graphs based upon user activity, construct other graphs based upon user activity, construct time-lines based upon user activity or construct maps based upon user activity.
