Database is an important part for any organization and this database needs to make secure from various attacks in the network. Although there are various techniques implemented in the network for the security of these databases. Hare we proposed detection of intrusion is detected that are possible in the databases and various authentication techniques are implemented to made this databases secure. Database security and authentication such as 3 factor authentication, intrusion response system, timestamp, triggers such factors provides more security to the database. The proposed methodology implemented here provides security, authentication, and database policies.

Pervasive Computing is an emerging technology which is primarily used for collaborating information. With the advent of this new technology several Challenges and Security issues comes into presence such as authentication of Users. The Existing methodology implemented for the Unceasing Verification in Pervasive Computing using Blended Identity is proposed which delivers Refuge from numerous attacks but since it involved with the implemented of RSA / DSA based algorithm computation cost and Communiqué time is high. Hence a new and efficient methodology is implemented for Pervasive Computing using Identity based Encryption which not only delivers refuge from numerous attacks but also takes less Calculation Cost and Communication time.
