Abstract

This disclosure provides techniques of verifying license compliance for a web application. A web application including a broadcast key and a license tag is generated. The generated web application is made available for review by a search engine. A query is communicated to the web search engine for a selected license tag. A list of reviewed web applications is received from the web search engine. The broadcast keys associated with each web application are evaluated to identify duplicate broadcast keys.

Claims

1. A computer implemented method of verifying license compliance for a web application, the method comprising:

generating an uncacheable response wrapper including a broadcast license and a license tag in response to request for a web application;

making the web application available for review by a web search engine by temporarily making the response wrapper cacheable if the request for the web application is received from a search engine;

communicating a query to the web search engine for a selected license tag;

receiving, in response to the communicated query, a list of a plurality of reviewed web applications whose generated response wrapper included the selected license tag from the web search engine;

evaluating a plurality of broadcast licenses associated with the plurality of reviewed web applications to identify duplicate broadcast licenses; and

reporting duplicate broadcast licenses among the reviewed web pages.

2. The method of claim 1, further comprising generating the license tag of the web application.

3. The method of claim 2, wherein generating the license tag comprises assigning a globally unique identifier.

4. The method of claim 1, further comprising generating the broadcast license.

5. The method of claim 4, wherein generating the broadcast license comprises:

retrieving a raw key;

applying a symmetric encryption to the raw key to generate a user key; and

applying a symmetric encryption to the user key to generate the broadcast license.

6. The method of claim 5, wherein retrieving a raw key comprises generating the raw key based upon information associated with a user.

7. The method of claim 6, wherein generating the raw key is based upon information associated with a licensed hardware platform.

8. At least one computer readable non-transitory medium storing instructions that, when executed by a computer, cause the computer to execute the method of claim 1.

9. A computer implemented method of verifying license compliance for a web application, the method comprising:

creating a web application that generates an uncacheable response wrapper including a broadcast license and a license tag in response to receiving a request for the web application from a web browser and generates a temporarily cacheable response wrapper including a broadcast license and a license tag in response to receiving a request for the web application from a search engine;

querying a search engine for a selected license tag;

receiving results from the queried search engine;

generating a list of a plurality of reviewed web pages based upon the results from the search engine;

evaluating a plurality of broadcast licenses associated with the plurality of reviewed web pages to identify duplicate broadcast licenses; and

reporting duplicate broadcast licenses among the reviewed web pages.

10. The method of claim 9, further comprising generating the broadcast license of the web application.

11. The method of claim 9, further comprising generating the license tag of the web application.

12. The method of claim 11, wherein generating the license tag comprises assigning a globally unique identifier.

13. The method of claim 9, wherein each reviewed web page includes the web application whose generated response wrapper includes the selected license tag.

14. At least one computer readable non-transitory medium storing instructions that, when executed by a computer, cause the computer to execute the method of claim 9.

15. A system for verifying license compliance for a web application, the system comprising:

a data store to store a broadcast license and a license tag associated with a web application;

a communication interface to support communication with a search engine or a web browser; and

a processor to;

generate an uncacheable response wrapper including a broadcast license and a license tag in response to receipt of a request for a web application from a web browser and generate a temporarily cacheable response wrapper including a broadcast license and a license tag in response to receiving a request for a web application from a search engine;

communicate a query for a selected license tag to a selected search engine via the communication interface;

receive results from the communicated query;

generate a list of reviewed web pages based upon the results, each reviewed web page including a selected web application whose generated response wrapper includes the selected license tag;

evaluate broadcast licenses associated with the reviewed web pages to identify duplicate broadcast licenses; and

report duplicate broadcast licenses among the reviewed web pages.
