“…This verification step essentially solves the false positive detection problem that arises in SVD based watermarking. The experimental results of proposed scheme shows that it is imperceptible and robust against different kinds of attacks [8][9]. For improved security using image compression, watermarking using DCT technique is used which has been combined with image compression technique by using improved adaptive Huffman encoding.…”

There are various existing techniques for cryptography and watermarking. The multimedia data security can be achieved by means of encryption and decryption i.e. cryptography. While watermarking is employed for hiding multimedia data using images. The proposed work focuses on the new method combining these strategies for producing effective solution to improve security of secrete multimedia data. In the proposed dissertation work the images will be used as multimedia data. The proposed method involves the encryption of data to be hid. The cover image is then used as the media for hiding encrypted data. The encrypted data combined with cover image is treated as embedded image. The embedded image then compressed using wavelet transforms compression.

“…The proposed work of this DICOM image encryption uses a fuzzy chaotic encryption card and for water-marking uses a discrete wavelet transform. The most confusing mechanism in image encryption is Arnold's transformation and this limitation of Arnold's transformation is overcome by this proposed method [8].…”

“…In their paper, Abdmouleh et al presented a partial cryptographic approach that was based on the digital wavelet transform (DWT) and was JPEG2000 compliant to ensure the safe transfer and storage of medical images [ 6 ]. Lakshmi et al presented a similar algorithm using a discrete wavelet transform (DWT), with the difference being that they used a fuzzy chaotic map for the watermarking [ 7 ]. In their paper, Cao et al presented a medical image encryption algorithm using edge maps that were derived from a source image.…”

“…The method in [ 5 ] focused on the embedding capacity, but no results are given with respect to other criteria, such as the correlation coefficients entropy, the number of pixel change rate (NPCR), or the uniform average change intensity (UACI). The methods in [ 6 , 7 ] are based on the digital wavelet transform (DWT) and allow for safe transport, but they do not provide suitable results with respect to the correlation coefficients. The results that were obtained in [ 8 ] are only suitable for the NPCR, and other values are not suitable.…”

In this paper, we present a new algorithm based on chaotic systems to protect medical images against attacks. The proposed algorithm has two main parts: A high-speed permutation process and adaptive diffusion. After the implementation of the algorithm in the MATLAB software, it is observed that the algorithm is effective and appropriate. Also, to quantitatively evaluate the uniformity of the histogram, the chi-square test is done. Key sensitivity analysis demonstrates that images cannot be decrypted whenever a small change happens in the key, which indicates that the algorithm is suitable. Clearly, part of special images is selected to test the selected plain-text, like an all-white image and an all-black image. Entropy results obtained from the implementation of the algorithm on this type of images show that the proposed method is suitable for this particular type of images. In addition, the obtained results from noise and occlusion attacks analysis show that the proposed algorithm can withstand against these types of attacks. Moreover, it can be seen that the images after encryption and decryption are of good quality; the measures such as the correlation coefficients, the entropy, the number of pixel change rate (NPCR), and the uniform average change intensity (UACI) have suitable values; and the method is better than previous methods.

“…However, RC5 can be broken by attackers due to its poor diffusion property in key computation [10], [11]. This can be overcome by using RC5 in combination with chaos to enhance the security level, where chaos sequences can be used for ciphering of medical images [12].…”

Chaos Based Enhanced RC5 Algorithm for Security and Integrity of Clinical Images in Remote Health Monitoring

et al. 2019

The demand for remote health monitoring will significantly increase in the near future due to a decrease in the doctor/patient ratio as the world population grows. In remote health monitoring, one of the major goals is to send patient's data to clinical experts at geographically distant locations. In this scenario, the importance of implementing security on patients' clinical information increases, so that this could not be either changed or read by an unauthorized person. Rivest Cipher (RC5) algorithm is a secure and simple encryption algorithm. Due to its simplicity, fast encryption, and low memory requirements, it is considered as a suitable block cipher for resource constraint environments, such as body area networks (BAN), although it can be broken by various attacks due to poor diffusion. In this paper, we propose a chaotic-based key scheduling algorithm for the RC5 in which round keys are generated based on 2-D chaotic maps and used as a symmetric key during the encryption and decryption process. Cipher feedback mode is adapted to further increase the diffusion property of the cipher. This chaos-based key is very difficult to trace, and the cipher is extremely hard to break. A strict security analysis of the proposed cipher is performed against several attacks. The experimental results have shown that the impact of this approach is significantly better than the conventional security mechanisms in case of BAN when applied to critical clinical images.INDEX TERMS Remote health monitoring, encryption, clinical images, wireless body area networks (WBAN), RC5, 2D-chaotic map.
