Solid Oak Software Inc, developer of CyberSitter, alleged on June 13, 2009 that an Internet-filtering program called Green Dam Youth Escort produced in China, and mandated by the Chinese government, contained stolen portions of the company's code.
"Solid Oak Software, the developer of CyberSitter, claims that the look and feel of the GUI used by Green Dam mimics the style of CyberSitter. But more damning, chief executive Brian Milburn said, was the fact that the Green Dam code uses DLLs identified with the CyberSitter name, and even makes calls back to Solid Oak's servers for updates" (http://www.pcmag.com/article2/0,2817,2348705,00.asp, accessed 06-13-2009).
Solid Oak Software Inc. said it will try to stop PC makers from shipping computers with the software.
"Solid Oak said Friday that it found pieces of its CyberSitter filtering software in the Chinese program, including a list of terms to be blocked, instructions for updating the software, and an old news bulletin promoting CyberSitter. Researchers at the University of Michigan who have been studying the Chinese program also said they found components of CyberSitter, including the blacklist of terms.
"Jinhui Computer System Engineering Co., the Chinese company that made the filtering software, denied stealing anything. "That's impossible," said Bryan Zhang, Jinhui's founder, in response to Solid Oak's charges.
"The allegations come as PC makers such as Dell Inc. and Hewlett-Packard Co. are sorting through a mandate by the Chinese government requiring that all PCs sold in China as of July come with the filtering software. Representatives of the two big U.S. companies said they are working with trade associations to monitor new developments related to the Chinese software" (http://online.wsj.com/article/SB124486910756712249.html, accessed 06-13-2009).
