Abstract: Remote database systems are becoming increasingly popular due to their potential usage in information storage. However, digital tuple data (e.g. bank balance, account details) are themselves vulnerable to security attacks. There are various methods are available to secure critical tuples. In this scheme we propose a new method in which data tuples are embedded in a container image. In this technique, we are using wavelet transform for hiding data in digital images by combining the use of adaptive hiding capacity function that hides secret data in the integer wavelet coefficients of the cover image with the optimum pixel adjustment (OPA) algorithm. The OPA algorithm is applied after embedding secret relational tuples to minimize the embedding error. The proposed system showed high hiding rates with reasonable imperceptibility compared to other steganographic systems.
