Method and system for ensuring authenticity of IP data served by a service provider
View Patent ↗A computer-implemented method and system identifies whether web content stored in a repository deviates from authentic web content being web content that is approved by authorized personnel of the web content prior to serving to a client requesting the web content. Web communications to the repository are monitored and web content is intercepted and analyzed in a safe environment for establishing that the web content conforms to a predetermined standard. If not, a web host serving the web content is alerted. In one embodiment, the web content is intercepted and analyzed prior to serving to the client and is served to the client only if either authenticated or after suitable modification to render it acceptable.
1. A computer-implemented method for identifying whether web content stored in a repository deviates from authentic web content, wherein authentic web content is web content that is approved by authorized personnel of the web content prior to serving to a client requesting said web content, said method comprising:
monitoring web communications to said repository;
intercepting said web content prior to serving the client;
analyzing the web content in a safe environment for establishing that the web content conforms to a predetermined standard; and
alerting a web host serving the web content if the web content does not conform to said standard;
wherein analyzing the web content includes:
(a) determining whether the web content includes dynamic content and, if so, determining whether the dynamic content conforms to predetermined known data representative of authentic actions associated with said dynamic content;
(b) extracting partial web content requested by the web browser;
(c) performing a computer simulation on the partial web content;
(d) if the computer simulation of the partial web content conforms to the predetermined authenticated experience relating to the partial web content, releasing the partial web content to the client while maintaining a copy for subsequent analysis; and
(e) iteratively repeating operations (c) and (d) on cumulative partial web content upon receipt of additional partial web content.
2. A computer-implemented method for preventing web content stored in a repository from being served to a client requesting said web content, said method comprising:
monitoring web communications to said repository;
intercepting said web content prior to serving the client;
analyzing the web content in a safe environment for establishing that the web content conforms to a predetermined standard; and
serving the web content to the client only if the web content conforms to said standard;
wherein analyzing the web content includes:
(a) determining whether the web content includes dynamic content and, if so, determining whether the dynamic content conforms to predetermined known data representative of authentic actions associated with said dynamic content;
(b) extracting partial web content requested by the web browser;
(c) performing a computer simulation on the partial web content;
(d) if the computer simulation of the partial web content conforms to the predetermined authenticated experience relating to the partial web content, releasing the partial web content to the client while maintaining a copy for subsequent analysis; and
(e) iteratively repeating operations (c) and (d) on cumulative partial web content upon receipt of additional partial web content.
3. The method according to claim 1 , wherein analyzing the web content includes determining whether static content has changed.
4. The method according to claim 3 , wherein determining whether static content has changed includes computing a signature of the static content and comparing the signature with a known signature of valid content.
5. The method according to claim 1 , including obtaining an identity of a web browser requesting the web content and performing a browser-specific simulation.
6. The method according to claim 1 , wherein analyzing the web content includes obtaining an image that the web content displays on a display device of the client and comparing the image with a predetermined representative image.
7. The method according to claim 1 , further including automatically redirecting the client to an alternative host storage device for uploading secure static web content if the web content does not operate as expected.
8. The method according to claim 1 , further including changing the web content in order to improve performance.
9. A non-transitory computer readable storage medium storing computer program code for performing the method of claim 1 when said program is run on a computer.
10. A non-transitory computer readable storage medium storing computer program code for performing the method of claim 2 when said program is run on a computer.
11. The method according to claim 1 , wherein determining whether the dynamic content conforms to a predetermined format includes decoding the web content as a logical HTML DOM tree, comparing the logical HTML DOM tree to a logical structure of known good-content stored in a database for said URL, or to logical policy rules configured for said URL allowing links, objects, scripts to be analyzed.
12. The method according to claim 2 , wherein determining whether the dynamic content conforms to a predetermined format includes decoding the web content as a logical HTML DOM tree, comparing the logical HTML DOM tree to a logical structure of known good-content stored in a database for said URL, or to logical policy rules configured for said URL allowing links, objects, scripts to be analyzed.
