First generation internet surveillance technologies
Making their appearance in 1996 when the number of websites was exploding, internet surveillance applications identified all modifications on a webpage, without any differentiation.The main disadvantage of such applications, based on "1st generation" technologies now considered run of the mill, is to alert the surveillance manager as soon as there is a change in date, advertising, headings or any other irrelevant items on the site.Such "noise" might be acceptable for one surveillance manager monitoring several dozen sites in a structured way, but it is extremely annoying when deploying the surveillance of thousands of different sources.
