There is a necessity to have secure data house where different types of clients can store their data. Secure data storage is a need of many clients like financial institutes, public services and government agencies. By using cryptographically strong hash functions, tampering detection can be done. This paper detects database intrusion using extensive hash calculations and comparisons. The detected data is further forensically analyzed in temporal and spatial domain using tiled bitmap algorithm. Advantage of this algorithm is the detection of multiple corruption events in same tile (time interval).
