Creating an access control policy based on consumer privacy preferences

Abstract

A system for generating an access control policy comprises a user interface for enabling a user to indicate a topic and a set of permissions. A document analyzer analyzes the content of a plurality of documents to find a set of documents relating to the topic. A property finder analyzes the content of a plurality of documents to find at least one distinguishing property of documents relating to the topic. A document selector selects the set of documents, based on the distinguishing property. An associating subsystem associates the set of permissions with the set of documents to obtain an access control policy.

1 . A system for generating an access control policy, comprising
 a user interface for enabling a user to indicate a topic and a set of permissions;   a document analyzer for analyzing the content of a plurality of documents to find a set of documents relating to the topic; and   an associating subsystem for associating the set of permissions with the set of documents to obtain an access control policy.   
     
     
         2 . The system according to  claim 1 , wherein the document analyzer comprises
 a property finder for analyzing the content of a plurality of documents to find at least one distinguishing property of documents relating to the topic; and   a document selector for selecting the set of documents, based on the distinguishing property.   
     
     
         3 . The system according to  claim 2 , wherein the document analyzer comprises a document pre-selector for selecting, based on the topic, the plurality of documents that are analyzed by the property finder. 
     
     
         4 . The system according to  claim 3 , wherein the document analyzer comprises a data type selector for selecting at least one data type, based on the topic; and
 wherein the document pre-selector is arranged for selecting a plurality of documents of the selected data type.   
     
     
         5 . The system according to  claim 1 , wherein the user interface is arranged for enabling the user to adapt the set of documents found by the document analyzer to obtain an adapted set of documents, and wherein the associating subsystem is arranged for associating the set of permissions with the adapted set of documents. 
     
     
         6 . The system according to  claim 2 , wherein the user interface is arranged for enabling the user to make a change to the at least one distinguishing property found by the property finder, and wherein the document selector is arranged for selecting the set of documents, based on the modified distinguishing property. 
     
     
         7 . The system according to  claim 1 , wherein the topic comprises a keyword. 
     
     
         8 . The system according to  claim 7 , wherein the document analyzer is arranged for searching for the keyword in the content of the documents. 
     
     
         9 . The system according to  claim 8 , wherein the document analyzer is arranged for finding further keywords, based on the content of the documents containing the keyword, and for selecting the set of documents, based on the further keywords. 
     
     
         10 . The system according to  claim 2 , wherein the at least one distinguishing property comprises a data type or a keyword. 
     
     
         11 . The system according to  claim 2 , wherein the property finder is arranged for applying natural language processing and/or an information retrieval method to the content of the plurality of documents. 
     
     
         12 . The system according to  claim 1 , further comprising an access control subsystem arranged for being configured with the access control policy obtained by the associating subsystem. 
     
     
         13 . A workstation comprising the system according to  claim 1 . 
     
     
         14 . A method of creating an access control policy, comprising
 enabling a user to indicate a topic and a set of permissions;   analyzing the content of a plurality of documents to find a set of documents relating to the topic; and   associating the set of permissions with the set of documents to obtain an access control policy.   
     
     
         15 . A computer program product comprising instructions for causing a processor system to perform the method according to  claim 14 .
