The determination of database security levels conclusion is of fuzziness and incompleteness after doing the classified protection of information system. In order to solve this problem,an intelligence determining and quantitative calculating method was proposed based on 2- D cloud model. Firstly,the rules were built for database security levels assessment according to the evaluation's result division between database and data itself; secondly,according to two groups of digital features in the cloud generator,the assessment cloud chart of the database security levels was constructed based on the 2- D cloud model; then,the projection diagram of levels evaluation was projected refering to the assessment cloud chart; finally,the quantitative determination was realized in the database security levels assessment. Experiments show that the method is simple and effective,and has a certain application value.
