WEB SERVER SYSTEM AND PROHIBTING METHOD OF REMOVING ADVERTISEMENT IN WEBPAGES USING A RANDOM DYNAMIC ID

摘要

A web server system and a method for preventing removing AD(ADvertisement) from a webpage by using an RDI(Random Dynamic ID) are provided to prevent a user from removing the AD from the webpage by changing an ID of a webpage code randomly. An RDI is generated by using a character string and a webpage is formed to change an ID value of the RDI included in the webpage whenever the webpage is loaded. The webpage includes an RDI function for generating the RDI having a predetermined length by generating the character string and selecting a part of the character string randomly. An RDI converter(30) includes a character string converter(33) converting the webpage into a character string type, an RDI inserter(35) inserting the RDI function into the webpage and changing the ID value of the webpage into a call value for calling the RDI function, and a restorer(37) changes the character string type webpage into a usual type. An interface provider(31) provides a web page, which is stored at a web storage unit, in user interface format.
