The Anti-Spyware Coalition (ASC) released their definitions of spyware today, available at the website. The document includes a table of technologies that could be classified as spyware, depending on factors including control, notice and consent. Another document (PDF) is available, with a summary of the nearly 400 public comments and the ASC's response.
The coalition also outlined their next project, called Risk Modeling, as a prelude to planned development of industry best practices. A draft is available for review and will be open for public comments until November 27.
