With the rapid development of Internet, the combination of Web technology and database technology is more and more closely, so the security of database security has become a very important part of information security. In the network environment, what kind of mechanism should be used to provide users with the generation, storage and access to data, and how to effectively ensure the safety of data, it becomes an urgent need to study the issue. High sensitive and confidential data encryption technology in the database storage, plays an increasingly important role, is the effective means to protect confidential data in the database in the storage and transmission, so can be used to model. In order to protect sensitive data in the Internet, put forward the model of encryption of sensitive data in the database, the database analysis, sensitive data classification based on the encryption engine, key management, key processing failure, the user sensitive data stored in the data base in the form of ciphertext. So even the database administrator can not easily obtain sensitive information from the user. After the attack caused the leakage of data it can also reduce the loss of system, ensure the security of data in the database to maximize. The experimental results show that the proposed model can effectively protect the security of sensitive data in database.
