Abstract

Provided are techniques in which a document accompanying a service is acquired, a natural language analysis is performed on the acquired document, a determination is made from the results of the natural language analysis whether an item defined in the access control policy is found in the acquired document and, when the item defined in the access control policy is found in the acquired document, the access control policy is referenced and access to the service controlled accordingly.

First claim

We claim:

1. A method for controlling access to a service provided by a server computing device, using computer processing, the method comprising:
acquiring, by a client computing device, a document provided by the server computing device, wherein the document comprises terms of service associated with the service;
performing, by the client computing device, natural language analysis on the acquired document, the natural language processing comprising:
annotating a term m the document with a attribute value; and
matching the attribute value with an attribute value of an access control policy;

determining, by the client computing device, from the results of the natural language analysis that an item defined in the access control policy is in the acquired document; and
refusing, by the client computing device, the service in response to the determining.

2. The method of claim 1 , wherein the determining further comprises adding a subject, resource or action annotation to a term in response to the results of natural language analysis having a term associated with the access control policy.

3. The method of claim 2 , wherein the determining further comprises matching a term having a predetermined relationship to an item defined in the access control policy in response to at least two terms with a subject, resource or action annotation having the predetermined relationship.

4. The method of claim 3 , wherein the predetermined relationship includes at least two terms with a subject, resource or action annotation in the same item of the document.

5. The method of claim 3 , wherein the predetermined relationship links at least one of a term having a subject annotation and a term having a resource annotation to a term having an action annotation in one sentence of the document.

6. The method of claim 1 , wherein the item specifies the refusing in accordance with access control content defined in the access control policy.

7. The method of claim 1 . wherein the item allows providing some of the service in accordance with access control content defined in the access control policy.

8. The method of claim 1 , wherein the item specifies the refusing in accordance with an access control policy application priority defined in the access control policy.

9. The method of claim 1 , wherein the item specifies a time period defined by the access control policy.

10. The method of claim 1 further comprising the computer executing the receiving a start request for the service, the acquiring the document being performed in response to receiving the start request.
