AN APPROACH FOR SECURELY SHARING DATA IN AN ENCRYPTED DATABASE

Abstract

Collaborative design and the integration of many applications are the causes for the demand of database security. Many database security techniques were developed which are having some vulnerabilities. So there is a need for database security technique which should provide both data privacy and should be able to protect the database from the attacks caused by intruders and malacious users. These are provided by Cryptographic techniques which can provide the database with high degree of security. Making the whole data encrypted is not advisable bacause of time constraint. So there is a trade of between performance and security. In this project there are two kinds of data one is personnal data and the other is common data. Personnal data gives the personnal details of each user which is very sensitive and the common data is a data which is non sensitive. So there is need of protecting only the personnal data. Therefore, personnal data is encrypted and stored in the database and decrypt...
