Abstract

Users may be presented with different viewing interfaces for a document based on a combination of factors relating to display rights possessed for the document and user specific information. In one implementation, the user'"'"'s location is used to determine portions of the document that can be displayed to the user. More particularly, access privileges to a document for a user are determined based on geographical location information of the user and based on access rights possessed for the document. Portions of the document may then be formatted for display to the user based on the determined access privileges.

Claims

1. A method comprising:

receiving a search query from a client used by a user;

identifying portions of a document that are relevant to the search query;

deriving user access privileges to the document based on information associated with the user and access rights associated with the document;

determining based on the derived user access privileges to the document and display right information for the document, one or more first portions of the document relevant to the search query to be readable by the user and one or more second portions of the document relevant to the search query to be unreadable by the user;

formatting the document based on the obtained access privileges and display right information, where formatting the document comprises;

processing the one or more first portions of the document determined to be readable by the user; and

processing the one or more second portions of the document determined to be unreadable by the user; and

providing the processed one or more readable first portions and a representation of content associated with the processed one or more unreadable second portions to the client in response to the request.

2. The method of claim 1, where the information associated with the user comprises one or more of:

information regarding a geographic location of the user;

information relating to whether the client used by the user accepts cookies; and

security information relating to the user.

3. The method of claim 1, further comprising:

storing a plurality of versions of the document, stored versions of the document including subsets of the document; and

selecting an appropriate version of the document from among the stored plurality of versions of the document responsive at least in part to the derived user access privileges to the document.

4. The method of claim 1, wherein the access rights associated with the document are granted by a source of the document for content of the document.

5. The method of claim 1, where the one or more second portions of the document include one or more images and the display right information indicates that the one or more images should be blocked when the portions of the document are provided to the client.

6. The method of claim 1, wherein processing the one or more second portions of the document determined to be unreadable by the user comprises blurring or blocking the one or more second portions of the document.

7. The method of claim 1, wherein the search query comprises one or more keywords and the identifying comprises identifying portions of the document that include the one or more keywords.

8. A non-transitory computer readable medium storing executable computer program instructions, the instructions executable to perform steps comprising:

receiving a search query from a client used by a user;

identifying portions of a document that are relevant to the search query;

deriving user access privileges to the document based on information associated with the user and access rights associated with the document;

determining based on the derived user access privileges to the document and display right information for the document, one or more first portions of the document relevant to the search query to be readable by the user and one or more second portions of the document relevant to the search query to be unreadable by the user;

formatting the document based on the obtained access privileges and display right information, where formatting the document comprises;

processing the one or more first portions of the document determined to be readable by the user; and

processing the one or more second portions of the document determined to be unreadable by the user; and

providing the processed one or more readable first portions and a representation of content associated with the processed one or more unreadable second portions to the client in response to the request.

9. The non-transitory computer readable medium of claim 8, where the information associated with the user comprises one or more of:

information regarding a geographic location of the user;

information relating to whether the client used by the user accepts cookies; and

security information relating to the user.

10. The non-transitory computer readable medium of claim 8, the steps further comprising:

storing a plurality of versions of the document, stored versions of the document including subsets of the document; and

selecting an appropriate version of the document from among the stored plurality of versions of the document responsive at least in part to the derived user access privileges to the document.

11. The non-transitory computer readable medium of claim 8, wherein the access rights associated with the document are granted by a source of the document for content of the document.

12. The non-transitory computer readable medium of claim 8, where the one or more second portions of the document include one or more images and the display right information indicates that the one or more images should be blocked when the portions of the document are provided to the client.

13. The non-transitory computer readable medium of claim 8, wherein processing the one or more second portions of the document determined to be unreadable by the user comprises blurring or blocking the one or more second portions of the document.

14. The non-transitory computer readable medium of claim 8, wherein the search query comprises one or more keywords and the identifying comprises identifying portions of the document that include the one or more keywords.

15. A device comprising:

a processor for executing computer program instructions; and

a non-transitory computer readable medium storing executable computer program instructions, the instructions executable to perform steps comprising;

providing a search query from a client used by a user to a server, wherein the server is adapted to;

identify portions of a document that are relevant to the search query;

derive user access privileges to the document based on information associated with the user and access rights associated with the document;

determine based on the derived user access privileges to the document and display right information for the document, one or more first portions of the document relevant to the search query to be readable by the user and one or more second portions of the document relevant to the search query to be unreadable by the user;

format the document based on the obtained access privileges and display right information, where formatting the document comprises;

processing the one or more first portions of the document determined to be readable by the user; and

processing the one or more second portions of the document determined to be unreadable by the user; and

providing the processed one or more readable first portions and a representation of content associated with the processed one or more unreadable second portions to the device in response to the request; and
