- One of the major problems in data mining is security. In the existing framework implementation was done in wireless sensor network. Existing system provides three contributions: 1. it is designed for multi-application environment, 2. it mitigates the impact of compromising attacks in single application environments and 3. it degrades the damage from the unauthorized aggregations. The two drawbacks in this scheme are, this CDAMA technique cannot be used for Database as a Service model and compromising the secret keys in sensor are very easy. In the proposed framework, Database as a Service model can be implemented through the bucketization algorithm and in the existing framework as sensors are easily compromised the secret keys are not secured whereas in the proposed framework trusted service providers are used to secure the secret keys. So the security level is increased in the proposed system when compared with the existing system.
