Mediator utilizing electronic content to enforce policies to a resource

1. A method of a mediator enforcing policies to a resource utilizing an electronic content, comprising:

receiving, by a mediator computing device of a mediator, a second share SK G2 from an owner server, wherein a first share SK G1 is provided to a member server of a member of a group by the owner server;

wherein the group is created by the owner server generating a group public key PK G and a group secret key SK G , and wherein the owner defines policies associated with the group;

wherein the member is added by the owner server to the group by generating the first share SK G1 from the group secret key SK G and a public key of the member, and the second share SK G2 from the group secret key SK G and a public key of the mediator;

wherein a user publishes an electronic content for the group, comprising the user encrypting the electronic content to the group public key PK G , wherein the electronic content includes a header and a payload; and

wherein the member obtains the encrypted electronic content;

further comprising;

the mediator receiving a request from the member for mediation, comprising the mediator receiving a dispatch of the header of the encrypted electronic content;

determining, by the mediator, whether the member is eligible to access the electronic content based at least in part on the policies associated with the group, if eligible, the mediator responding to the request for mediation with a member accessible header, wherein the member accessible header includes the header after application of SK G2 ;

wherein the member obtains a secret based on SK G1 and the member accessible header; and

wherein the member decrypts the payload of the electronic content using the secret.

2. The method of claim 1 , wherein the electronic content provides access to the resource.

3. The method of claim 1 , wherein the electronic content provides access to use of a physical resource.

4. The method of claim 1 , wherein the resource includes at least one financial instrument, and the electronic content provides access to the financial instrument.

5. The method of claim 1 , wherein the policies associated with the group control access to the resource.

6. The method of claim 1 , wherein the policies associated with the group control access to the group.

7. The method of claim 6 , wherein the policies associated with the group control access to add resources to the group.

8. The method of claim 1 , wherein the policies associated with the group control access to administer the group.

9. The method of claim 1 , wherein the electronic content is stored at a custodian.

10. The method of claim 1 , wherein the mediator determines which policy applies to the resource through the header.

11. The method of claim 1 , wherein the mediator determines which policy applies to the resource by accessing policy information.

12. The method of claim 1 , wherein the mediator determines which policy applies to the resource through the header, and by accessing policy information.

13. The method of claim 1 , wherein the determining, by the mediator, whether the member is eligible to access the resource is additionally based at least in part on member state information.

14. The method of claim 13 , wherein the member state information includes assigned location information.

15. The method of claim 14 , wherein the assigned location information is received from a radio receiver of the user.

16. The method of claim 13 , wherein the member state information includes attestations of eligibility to access properties of the resource.

17. The method of claim 13 , wherein the member determines whether the member has access to the resource or properties of the resource based on the member state information.

18. The method of claim 17 , wherein the member server runs a trusted agent, and wherein the trusted agent verifies that the member has access to the resource or properties of the resource based on the member state information.

19. The method of claim 1 , wherein resource policies are set or applied by any user.

20. The method of claim 19 , wherein the determining, by the mediator, whether the member is eligible to access the resource is additionally based at least in part on the resource policies.

21. The method of claim 1 , wherein user policies are set or applied by any user.

22. The method of claim 21 , wherein the determining, by the mediator, whether the member is eligible to access the resource is additionally based at least in part on the user policies.

23. A mediator server operative to enforcing policies to a resource using an electronic content, comprising a mediator of the mediator server operative to:

receive a second shares SK G2 from an owner server, wherein a first share SK G1 is provided to a member server of a member by the owner server;

wherein a group is created by the owner server comprising generating a group public key PK G and a group secret key SK G ;

wherein the member is added by the owner server to the group by generating the first share SK G1 from the group secret key SK G and a public key of the member, and the second share SK G2 from the group secret key SK G and a public key of the mediator;

wherein a user publishes an electronic content for the group, comprising the user encrypting the electronic content to the group public key PK G , wherein the electronic content includes a header and a payload; and

wherein the member obtains the encrypted electronic content;

the mediator of the mediator server further operative to:

receive a request from the member for mediation, comprising the mediator receiving a dispatch of the header of the encrypted electronic content;

receive a request, by the member, for mediation, comprising the mediator receiving a dispatch of the header of the encrypted electronic content from the member;

determine whether the member is eligible to access the electronic content based at least in part on the policies associated with the group, if eligible, the mediator responding to the request for mediation with a member accessible header, wherein the member accessible header includes the header after application of SK G2 ;

wherein the member obtains a secret based on SK G1 and the member accessible header; and

wherein the member decrypts the payload of the electronic content using the secret.

24. The mediator server of claim 23 , wherein the electronic content provides access to the resource.

25. The mediator server of claim 23 , wherein the electronic content provides access to use of a physical resource.

26. The mediator server of claim 23 , wherein the resource includes at least one financial instrument, and the electronic content provides access to the financial instrument.

27. The mediator server of claim 23 , wherein the policies associated with the group control access to the resource.

28. The mediator server of claim 23 , wherein the determining, by the mediator, whether the member is eligible to access the resource is additionally based at least in part on member state information.

29. The mediator server of claim 23 , wherein resource policies are set or applied by any user.

30. The mediator server of claim 23 , wherein user policies are set or applied by any user.
