Systems and methods are provided for protecting electronic content from the time it is packaged through the time it is experienced by an end user. Protection against content misuse is accomplished using a combination of encryption, watermark screening, detection of invalid content processing software and hardware, and/or detection of invalid content flows. Encryption protects the secrecy of content while it is being transferred or stored. Watermark screening protects against the unauthorized use of content. Watermark screening is provided by invoking a filter module to examine content for the presence of a watermark before the content is delivered to output hardware or software. The filter module is operable to prevent delivery of the content to the output hardware or software if it detects a predefined protection mark. Invalid content processing software is detected by a monitoring mechanism that validates the software involved in processing protected electronic content. Invalid content flows can be detected by scanning the information passed across system interfaces for the attempted transfer of bit patterns that were released from an application and/or a piece of content management software.

Techniques for transmitting graphical images in a network environment are described. According to the techniques, the amount of data of the graphical images that is transmited is customized in accordance with client and/or server supplied information. The techniques enable graphical images to be transmitted more efficiently than previously possible, thus saving precious network bandwidth and reducing transmision time. The invention is particularly suitable for network (Internet or Internet) implementations wherein graphical images often need transferred.
