A man working in Shenzhen, South China's Guangdong province, said his identify card information was illegally used for many years, which has incurred him more than 79 million yuan ($11 million) in debts and 32 lawsuits.

Liu Hanting, who has been working in Shenzhen for about 20 years, said that during a regular check of his ID in 2011 he happened to find the photo used in the online National Citizen Identify Information Center system was not of him, but a stranger's face.

He called the public security bureau of his hometown in Huilai County of Guangdong Province and applied at the local police station for a new ID card by sending in personal documents.

But when the new ID card arrived, Liu found the photo had not been changed.

Then in 2012, Liu was informed by a bank in Shenzhen that his credit card debts totaled 370,000 yuan. He also learned that his identity had been used in 32 lawsuits involving over 79 million yuan of debts.

Liu also found information regarding his household registration was wrong. It stated that he had a wife and two sons, the former being implicated in about 50 lawsuits.

He said he entrusted an official at the police station in his hometown to apply for household registration for his twin daughters in 2009, and suspects that his personal information could have been leaked at the time.

Liu has reported to police who are investigating the case.
