Patent ID: 7917618

Claim:
A system for monitoring Web page content associated with processing a resource request, the system comprising: a client computing component associated with a client computing device, wherein the client computing component is operable to render Web page content associated with processing a first resource request; and a processing component operable to: generate a sample image corresponding to the Web page content rendered by the client computing component, wherein the sample image comprises a pixel intensity value for each pixel in the sample image; compare the sample image to a corresponding averaged reference image to identify a compared image, wherein the corresponding averaged reference image is determined from averaging a respective pixel intensity value for each pixel in a plurality of reference images, wherein each of the plurality of reference images correspond to Web page content associated with processing the first resource request, and wherein the compared image includes an intensity value for each pixel corresponding to the difference between the sample image and the corresponding averaged reference image; weight the compared image using an image weight map to produce a weighted compared image; determine whether a sum of the intensity values for each pixel in the weighted compared image exceeds a threshold; and transmitting an alert message if the threshold is exceeded.
