“…From this comparison, one can conclude that maximum degrade in PSNR is 4.1757 dB and minimum degrade in PSNR is 2.7002 at 4 bpp; and maximum degrade in PSNR is 4.0277 dB and minimum degrade in PSNR is 1.0208 at 2 bpp; and maximum degrade in PSNR is 4.81 dB and minimum degrade in PSNR is 0.1164 at 1 bpp. PSNR is higher than 30 dB which shows that composite image still has good visual quality after JPEG2000 attack and hence imperceptibility is maintained [15]. The correlation and SIM found at different bit rates are highly correlated and similar, which confirms the robustness of the proposed algorithm.…”

“…The larger the PSNR, the image quality is better. In general, a composite image is acceptable by human perception if its PSNR is greater than 30 dB [15]. SIM is generally between 0 to 1.…”

In this paper, data hiding algorithm using Discrete Wavelet Transform (DWT) and Arnold Transform is proposed. The secret data is scrambled using Arnold Transform to make it secure. Wavelet subbands of a cover image are obtained using DWT. The scrambled secret data is embedded into significant wavelet coefficients of subbands of a cover image. The proposed algorithm is robust to a variety of attacks like JPEG and JPEG2000 compression, image cropping and median filtering. Experimental results show that the PSNR of the composite image is 1.05 dB higher than the PSNR of existing algorithms and capacity is 25% higher than the capacity of existing algorithms.

“…PSNR between the cover and stego images without and with OPAP are shown in Tables 1, 2 and 3 for different values of k, where k is number of secret bits embedded into peak wavelet coefficients of subbands of the cover image. From these Tables, one can observe that PSNR between cover images and stego images decreases as the value of k is increased but it is highly acceptable by the human visual system as upto k=3, PSNR is around 40 dB [13]. Also, when OPAP is blended with the proposed technique, there is maximum 2 dB improvement in PSNR of stego images.…”

This paper proposes a block-based high capacity steganography technique for digital images. The cover image is decomposed into blocks of equal size and the largest pixel of each block is found to embed the secret data bits and also the smallest pixel of each block is used for embedding to enhance the capacity. Embedding of secret data is performed using the concept that the pixel of a cover image has only two states — even and odd. Multilevel approach is also combined in the proposed technique to achieve high embedding capacity. In order to make the proposed technique more secure, a key is generated using embedding levels, block size, pixel embedding way, encryption parameters, and starting blocks of each embedding levels. Embedding capacity and visual quality of stego images generated by the proposed steganography technique are higher than the existing techniques. Steganalysis tests have been performed to show the un-detectability and imperceptibility of the proposed technique.
