Abstract

The present invention provides methods for using abstractions of people, including dynamic and static groups of people, to enhance the efficiency of the specification and automation of policies for sharing information between users with a “need-to-know.” An instance of the present invention can also provide these users information based on a “time-to-know.” By providing access to information based on group affiliation and properties of the content of the information, the present invention maintains optimal information privacy while minimizing encumbrances to sharing data with appropriate users and even at appropriate times. The present invention can be integrated with other communication technologies to facilitate access to information in a time appropriate manner. Other instances of the present invention employ automated and semi-automated, mixed-initiative techniques, to make information-sharing decisions. Additional instances of the present invention include the employment of machine-learning techniques to facilitate construction of access policies from the actions or profile of a single user or a community of users, including the construction of automated sharing agents that work in an automated or mixed-initiative manner to respond to real-time requests for information.

Claims

1. A system to facilitate information access control, comprising:

memory; and

one or more processors coupled to the memory and configured to;

receive an access request for a data item owned by a data item owner, the access request being based on a request from a requesting user,

determine whether the requesting user is a member of a dynamically created group of users based on an activity of the requesting user,

dynamically select an access policy based on the dynamically created group of users to which the requesting user is determined to belong, and

selectively provide access to the data item to the requesting user based on the access policy and further based on an urgency of the data item.

2. The system of claim 1, wherein the urgency of the data item is an inferred urgency of the data item.

3. The system of claim 1, wherein the urgency of the data item is a time urgency of the data item.

4. The system of claim 1, wherein the urgency of the data item is an inferred time urgency of the data item.

5. The system of claim 1, wherein the one or more processors are configured to dynamically select the access policy further based on a context of the data item owner;

and

wherein the data item owner and the requesting user are not same.

6. The system of claim 5, wherein the one or more processors are configured to dynamically select the access policy based on communication means that are available for use by the data item owner.

7. The system of claim 5, wherein the one or more processors are configured to dynamically select the access policy based on an anticipated activity level of the data item owner.

8. The system of claim 5, wherein the one or more processors are configured to dynamically select the access policy based on an activity performed by the data item owner.

9. The system of claim 5, wherein the one or more processors are configured to dynamically select the access policy based on at least one of a location of the data item owner or an anticipated location of the data item owner.

10. The system of claim 5, wherein the one or more processors are configured to dynamically select the access policy based on a forecast of a wait time until the data item owner is able to act on the access request.

11. A method of facilitating information access control using at least one processor of a processor-based system, the method comprising:

receiving an access request for a data item owned by a data item owner, the access request being based on a request from a requesting user;

determining whether the requesting user is a member of a dynamically created group of users based on an activity of the requesting user;

dynamically selecting an access policy based on the dynamically created group of users to which the requesting user is determined to belong; and

selectively providing access to the data item to the requesting user based on the access policy and further based on an urgency of the data item.

12. The method of claim 11, wherein the urgency of the data item is an inferred urgency of the data item.

13. The method of claim 11, wherein the urgency of the data item is a time urgency of the data item.

14. The method of claim 11, wherein the urgency of the data item is an inferred time urgency of the data item.

15. The method of claim 11, wherein dynamically selecting the access policy comprises:

dynamically selecting the access policy further based on a context of the data item owner; and

wherein the data item owner and the requesting user are not same.

16. The method of claim 15, wherein dynamically selecting the access policy comprises:

dynamically selecting the access policy based on communication means that are available for use by the data item owner.

17. The method of claim 15, wherein dynamically selecting the access policy comprises:

dynamically selecting the access policy based on at least one of an anticipated activity level of the data item owner or an activity performed by the data item owner.

18. The method of claim 15, wherein dynamically selecting the access policy comprises:

dynamically selecting the access policy based on at least one of a location of the data item owner or an anticipated location of the data item owner.

19. The method of claim 15, wherein dynamically selecting the access policy comprises:

dynamically selecting the access policy based on a forecast of a wait time until the data item owner is able to act on the access request.

20. An article comprising a computer-readable storage medium that stores logic, the logic comprising:

means for determining whether a requesting user is a member of a dynamically created group of users based on an activity of the requesting user in response to receipt of an access request for a data item owned by a data item owner, the access request being based on a request from the requesting user;

means for dynamically selecting an access policy based on the dynamically created group of users to which the requesting user is determined to belong; and

means for selectively providing access to the data item to the requesting user based on the access policy and further based on an urgency of the data item.
