China's plan to enforce internet-filtering software to be installed on all PC's and laptops to be sold in China, may not go as well as it had hoped.

Solid Oak Software of Santa Barbara said Friday that China has stolen its own programming code.

The Green Dam-Youth Escort filtering software that China plans to have installed on all computers sold in China from July 1 contains stolen programming codes from a company in California.

Solid Oak Software of Santa Barbara said Friday that parts of its filtering software, which is designed for parents, is the exact same as the one planned to be used in China, according to a report by the Associated Press.

Solid Oak's founder, Brian Milburn, said he will seek an injunction against the Chinese developer that built the software.

I don't know how far you can try and reach into China and try to stop stuff like this. We're still trying to assess what they're doing, he said.

With more than 250 million Internet users, China employs some of the world's strictest controls over what citizens can view on the Internet.

A report released Thursday by University of Michigan researchers who examined the Chinese software supports Solid Oak's claim that the Green Dam software contains pirated code. The report also found serious security vulnerabilities that could allow hackers to hijack PCs running the Chinese software.
