1. A system that facilitates information access control, comprising:

  • at least one processor coupled to memory, the at least one processor executes;

    a component that receives an access request for a data item from a requesting user;

    an access control component that;

    assigns one or more members to a dynamically created group of users, each member being assigned to the dynamically created group of users based on;

    a characteristic for the dynamically created group of users, the characteristic comprising at least one activity performed by the one or more members of the dynamically created group of users, a location of the one or more members, and availability of the one or more members; and

    the member'"'"'s association with the at least one activity, the location and the availability, wherein the member'"'"'s association with the at least one activity is determined based on a current activity of the member, and wherein the member'"'"'s association with the location is determined based on accessibility to the member, at a current location of the member, of at least one communication means to communicate with members of the dynamically created group of users; and

    processes the data item access request via utilization of at least one access policy stored on the memory based, at least in part, on membership of the requesting user in the dynamically created group of users and at least one content property associated with the data item that indicates access rights for the members of the dynamically created group; and

    an access policy agent component that constructs the at least one access policy utilizing, at least in part, at least one selected from the group consisting of multiple dimensions of trust, machine learning techniques, and cost-benefit analysis;

    whereinthe access policy agent component further employs at least one selected from the group consisting of a logical clustering of users and a statistical clustering of users, the clustering based, at least in part, on at least one information sharing profile employed by the users, the information sharing profile comprising a profile of settings disseminated among the users for at least one selected from the group consisting of utilization by the users and modification by the users.
