China will set up a database for residents' credit with the aim of preventing officials' corruption during their asset declarations, Cui Hairong, deputy director of the National Bureau of Corruption Prevention, said on Monday, The Beijing Times reports.

Cui said the database, which is based on information of the second generation ID cards, will not only cover identity information, such as personal information and fingerprint, but also the resident's property, income and information on their household members.

Cui said that with such a database, it would be convenient to obtain information on any official who owns three house units, but with only one unit under his or her name, and the other two units registered by his or her family members. So the invisible income would be found out more easily to determine the officials' property status.

According to the report, the detailed plan to set up the code system would be implemented at the end of this year.
