A coalition of Canadian industry groups, including the Canadian Chamber of Commerce, the Canadian Marketing Association, the Canadian Wireless Telecommunications Association and the Entertainment Software Association of Canada, are demanding legalized spyware for private enforcement purposes. The demand comes as part of a review of anti-spam and spyware legislation in Canada.
The potential scope of coverage is breathtaking: a software program secretly installed by an entertainment software company designed to detect or investigate alleged copyright infringement would be covered by this exception. This exception could potentially cover programs designed to block access to certain websites (preventing the contravention of a law as would have been the case with SOPA), attempts to access wireless networks without authorization, or even keylogger programs tracking unsuspecting users (detection and investigation).
