First Claim
1. An apparatus for detecting illegitimate change of web resources comprising:
- a web resource protection processing sub-system for generating and inserting illegitimate change detecting information into corresponding a web resource, the illegitimate change detecting information being used to detect whether or not the web resource is changed illegitimately; and
a web resource change detecting sub-system for judging whether or not the corresponding web resource is illegitimately changed, based on the illegitimate change detecting information contained in the web resource when the web resource is executed by a communication network.

Abstract
The invention relates to an apparatus and method for detecting an illegitimate change of web resources, and more particularly, to an apparatus and method for detecting an illegitimate change of web resources, which is capable of detecting whether or not HTML, XHTML and XML documents, general text documents, binary data of graphic files linked to HTML document and the like are illegitimately changed using XML digital signature and XML encryption when inquiring corresponding web page. It is characteristic of the present invention to confirm in real time whether or not the web page is illegitimately changed by inserting an illegitimate change detecting information into the web page by a web server administrator and executing corresponding web page through a web browser by a user. Meanwhile, the illegitimate change detecting process can be simultaneously applied to the graphic files used at the web page and the linked external files existing in an independent type, as well as the text information of the web page, thereby effectively protecting web resources. Further, specific resources are encrypted and only a specific operator who has a decryption key for decrypting the encrypted resources can inquire the resources, thereby additionally providing confidentiality.
