Abstract: The paper is aimed for a wavelet based steganographic/watermarking technique in frequency domain termed as WASTIR for secret message/image transmission or image authentication.Number system conversion of the secret image by changing radix form decimal to quaternary is the pre-processing of the technique.Cover image scaling through inverse discrete wavelet transformation with false Horizontal and vertical coefficients are embedded with quaternary digits through hash function and a secret key.Experimental results are computed and compared with the existing steganographic techniques like WTSIC, Yuancheng Li's Method and Region-Based in terms of Mean Square Error (MSE), Peak Signal to Noise Ratio (PSNR) and Image Fidelity (IF) which show better performances in WASTIR.
