Xiang Jun, a marketing officer for zhenai.com, an online website providing dating services, confirmed that it is hard for Internet companies to verify customers' information.
"It's easy to fake documents, and we lack effective ways to authenticate these documents," said Xiang.
Jiang was sentenced to four and a half years in jail for fraud in August 2012, after criminal charges were filed against him, said Xiao.
