China will set up a database for residents' credit with the aim to prevent officials' corruption during their assets declarations, Cui Hairong, deputy general-director of the National Bureau of Corruption Prevention, said on Monday, The Beijing Times reported.

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 be added with the resident's property, income and information of their household members.

Cui said that with such a database, it would be convenient to search a person's information to prevent corruption effectively.

With an example, Cui explained that an official owned 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, causing a complex investigation. Under the database, 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 the year.
