Secure and robust digital image watermarking scheme using logistic and RSA encryption

System security is a basic aspect of data sharing. Aspires have been made to exhaust particular defects over the web. For this, different creative usage and security methods have been made. The measure of information exchange isn't a factor. The major factor is, how much it's secure, the channel gives while transmitting information. Cryptography is one such structure, which grants secure information transmission without losing its protection and uprightness. In light of the key circulation, cryptography is also assembled into two critical forms Symmetric Key Cryptography as well as Asymmetric Key Cryptography. RSA is one of the best conspicuous public-key cryptography based algorithms is unequivocally utilized for encryption/decryption. It's far based on the logical arrangement of factorization of strongly enormous whole numbers which is a compute-intensive way. In this paper, we have provided a novel, secure and profitable information communication system dependent on the RSA algorithm. Mystery updating signal dealing with systems have been proposed in the exploration for the two data transmission and the channel estimation stages. The proposed one facilitates the advantages of both RSA calculation and One Time Password (OTP) produced by the sender and got just by the endorsed customer. Despite that not at all like conventional RSA algorithm, in this work we embrace perfect key assurance by particle swarm optimization (PSO) during both encryption and decryption. The use of PSO for perfect key decision makes the general technique proficient by extending the security level and making the computation procedure very easy.

In this research study, a multipurpose image water-marking approach was developed for delivering selfrecovery, ownership verification and tamper localization of the cover image. For robust watermarking, color and grayscale images were used to deliver wide applicability and generalization to proposed work. Initially, the cover image was converted into wavelet domain by using Integer Wavelet Transform (IWT) and then the logo image was encrypted by using chaotic logistic mapping. This procedure makes the digital image free from false positive error and also helps to provide decent capacity. After encryption and transformation, Least Significant Bit (LSB) was used to provide self-recovery feature as well as to locate the tempered region in the digital image. Then, asymmetric encryption algorithm: Rivest-Shamir-Adleman (RSA) was utilized to improve the hidden data security with high computational efficiency, and good embedding capacity. Finally, the experimental outcome shows that the proposed approach delivers a high secure network with low computational complexity by means of entropy value and Peak Signal-to-Noise Ratio (PSNR). The proposed approach improved PSNR value upto 19 dB and entropy value upto 0.07-0.7 compared to the existing methods: Discrete Cosine Transform (DCT) + Arnold transform and differential evolution algorithm.

“…e original image encryption algorithms were based on the "confusion-di usion" encryption framework proposed by Fridrich. With the continuous development of hardware technology and cryptanalysis technology, most of the current image encryption algorithms are designed by integrating various technologies, such as DNA coding [1], optical technology [2], cellular automata [3,4], and asymmetric cryptosystems [5], which guarantees the security of image transmission and storage on some resource sharing platforms. However, with the rapid development of communication networks, the increasing demand for real-time transmission, and increasing image sizes, ensuring the security and real-time performance of the transmission of massive images in bandwidth-constrained networks has become an urgent problem that needs to be solved.…”

is paper proposes a new image compression-encryption algorithm based on a meaningful image encryption framework. In block compressed sensing, the plain image is divided into blocks, and subsequently, each block is rendered sparse. e zigzag scrambling method is used to scramble pixel positions in all the blocks, and subsequently, dimension reduction is undertaken via compressive sensing. To ensure the robustness and security of our algorithm and the convenience of subsequent embedding operations, each block is merged, quantized, and disturbed again to obtain the secret image. In particular, landscape paintings have a characteristic hazy beauty, and secret images can be camou aged in them to some extent. For this reason, in this paper, a landscape painting is selected as the carrier image. After a 2-level discrete wavelet transform (DWT) of the carrier image, the lowfrequency and high-frequency coe cients obtained are further subjected to a discrete cosine transform (DCT). e DCT is simultaneously applied to the secret image as well to split it. Next, it is embedded into the DCT coe cients of the low-frequency and high-frequency components, respectively. Finally, the encrypted image is obtained. e experimental results show that, under the same compression ratio, the proposed image compression-encryption algorithm has better reconstruction e ect, stronger security and imperceptibility, lower computational complexity, shorter time consumption, and lesser storage space requirements than the existing ones.
