High security data hiding using image cropping and LSB least significant bit steganography
Khalid A. Al-Afandy,Osama S. Faragallah,Ahmed Elmhalawy,El-Sayed M. El-Rabaie,Gh. M. El-Banby +4 more
TL;DR: Experimental results shows that the proposed high security data hiding approach using image cropping and Least Significant Bit (LSB) steganography is more secure compared with the other traditional approaches.
Journal ArticleDOI
Robust hybrid watermarking techniques for different color imaging systems
Khalid A. Al-Afandy,Walid El-Shafai,El-Sayed M. El-Rabaie,Fathi E. Abd El-Samie,Osama S. Faragallah,Osama S. Faragallah,Ahmed Elmhalaway,Ahmed M. Shehata,Ghada M. El-Banby,M. M. El-Halawany +9 more
TL;DR: Comparisons are based on the subjective visual results to detect any degradation in the watermarked image in addition to the objective results of the Peak Signal-to-Noise Ratio (PSNR) and Normalized Correlation of the extracted watermark to test and evaluate the performance efficiency of the proposed watermarking techniques.
Journal ArticleDOI
A Comparative Study For Color Systems Used In The DCT-DWT Watermarking Algorithm
Proceedings ArticleDOI
A hybrid scheme for robust color image watermarking using DSWT in DCT domain
Khalid A. Al-Afandy,Osama S. Faragallah,El-Sayed M. El-Rabaie,Fathi E. Abd El-Samie,Ahmed Elmhalawy +4 more
TL;DR: This paper proposes a hybrid robust image watermarking scheme based on three levels of Discrete Stationary Wavelet Transform (DSWT) in the Discrete Cosine Transform (DCT) domain that is compared with other state-of-the-art schemes.
Proceedings ArticleDOI
Efficient color image watermarking using homomorphic based SVD in DWT domain
Khalid A. Al-Afandy,Osama S. Faragallah,El-Sayed M. El-Rabaie,Fathi E. Abd El-Samie,Ahmed Elmhalawy +4 more
TL;DR: Experimental results ensure that the proposed watermarking approach is both robust and immune to attacks studied in this paper compared with the other traditional approaches.
