A Novel Genetic Algorithm Based Data Embedding Technique in Frequency Domain Using Z Transform (ANGAFDZT)

An Image Authentication Technique in Frequency Domain using Genetic Algorithm (IAFDGA)

“…In comparison with existing [1] it is seen that the proposed technique has higher patload compared to the existing [1]. In comparison with existing [2] it is seen that the proposed technique has higher capacity and better PSNR compared to the existing [1]. The maximum capacity of the existing [1] is 216000 and existing [2] 36850 is where as the maximum capacity of the proposed technique is 393210.…”

The maximum capacity of the existing [1] is 216000 and existing [2] 36850 is where as the maximum capacity of the proposed technique is 393210. The average value of PSNR for the proposed technique is 38.85 which is much higher than the existing [2] average value 29.43.…”

“…Table II shows the comparison of PSNR values and capacity of the proposed technique and the existing Mandal J. K. et al [1] and Chin-Chen Chang et al [2]. In comparison with existing [1] it is seen that the proposed technique has higher patload compared to the existing [1]. In comparison with existing [2] it is seen that the proposed technique has higher capacity and better PSNR compared to the existing [1].…”

“…In this paper an image authentication and data hiding technique has been proposed. Most of the previous work [12], [11], [1], [2], [10] uses minimum bits for hiding but the present algorithm has high capacity with minimum/undetectable change of the visibility. Rest of the paper is organized as follows.…”
