Alibaba, China’s biggest e-commerce company, will implement real-name authentication for corporate and individual users on its China site to improve anti-fraud measures for business-to-business activities, the company said.

All registered users must have real-name authentication before September 23. Any one failing to do it will be banned from posting product information online, and face a removal of their information.

This move is seen as an effort by Alibaba to improve its business strategy after a crisis this year. Earlier the company’s announcement showed that there were 1,219 and 1,107 sellers suspected fraud in 2009 and 2010 in Alibaba’s business-to-business platform.
