Considering the information system medical images are the most sensitive and critical types of data. Transferring medical images over the internet requires the use of authentication algorithms that are resistant to attacks. Another aspect is confidentiality for secure storage and transfer of medical images. The proposed study presents an embedding technique to improve the security of medical images. As a part of preprocessing that involves removing the high-frequency components, Gaussian filters are used. To get LL band features CDF9/7 wavelet is employed. In a similar way, for the cover image, the LL band features are obtained. In order to get the 1st level of encryption the technique of alpha blending is used. It combines the LL band features of the secret image and cover images whereas LH, HL, and HH bands are applied to Inverse CDF 9/7. The resulting encrypted image along with the key obtained through LH, HL, and HH bands is transferred. The produced key adds an extra layer of protection, and similarly, the receiver does the reverse action to acquire the original secret image. The PSNR acquired from the suggested technique is compared to PSNR obtained from existing techniques to validate the results. Performance is quantified in terms of PSNR. A Spartan 6 FPGA board is used to synthesize the complete architecture in order to compare hardware consumption.

“…In this research study, our focus is to propose a lightweight image encryption scheme using chaos cryptography. Many research articles have been published in reputed journals on image encryption using chaos cryptography, such as [15][16][17]. The existing image-based encryption techniques can be divided into symmetric chaos-based image encryption schemes [18][19][20][21][22][23], asymmetric chaos-based image encryption schemes [24][25][26][27], and hybrid chaos-based image encryption schemes [28,29].…”

The secret keys produced by current image cryptosystems, which rely on chaotic sequences, exhibit a direct correlation with the size of the image. As the image dimensions expand, the generation of extensive chaotic sequences in the encryption and decryption procedures becomes more computationally intensive. Secondly, a common problem in existing image encryption schemes is the compromise between privacy and efficiency. Some existing lightweight schemes reveal patterns in encrypted images, while others impose heavy computational burdens during encryption/decryption due to the need for large chaotic sequences. In this study, we introduce a lightweight image encryption scheme that involves partitioning the image into uniformly sized tiles and generating a chaotic sequence accordingly. This approach diminishes the necessity to create extensive chaotic sequences equal to the tile size, which is significantly smaller than the original image. As a result, it alleviates the processing burden associated with generating sequences equivalent to the original image size. The results confirm that our proposed scheme is lightweight and secure compared to the latest state-of-the-art image encryption schemes. Additionally, sensitivity analysis demonstrates that the proposed image encryption technique, with a UACI value of 33.48 and NPRC value of 99.96, affirms its resistance to differential attacks.

Considering the current dependency on digital technology in modern society, the protection of multimedia is highly important. Encryption is vital in modern digital communication, ensuring data confidentiality, authentication, integrity, and non-repudiation. Multimedia encryption-based security techniques are becoming increasingly important as they allow for the secure sharing of multimedia content on digital platforms. This survey aims to review the state of secure and privacy-preserving encryption schemes applicable to digital multimedia, such as digital images, digital video, and digital audio. An extensive analysis of the existing cryptography schemes and multimedia encryption algorithms will be conducted to give an extensive overview of the current state of security encryption schemes specifically designed for digital multimedia technology. The survey results will be used to understand better the effectiveness and reliability of secure multimedia encryption schemes and contribute to developing efficient and secure encryption schemes in the future.
