“…e chaotic system has many unique features similar to the counterpart of the cryptosystem, such as bulky data capacity and high redundancy [4], which are difficult to handle by using text encryption techniques. In the last two decades, many new image encryption schemes were proposed, and researchers proposed many image encryption schemes by applying various technologies, such as compressive sensing [5][6][7], DNA coding [8][9][10][11][12][13], quantum theory [14][15][16][17], chaos systems [18][19][20][21][22][23][24][25][26][27][28], S-box [29], and networks [30,31].…”

To improve the dynamical behaviors of 1D chaotic maps, a new linear-delay-modulation method (LDM) is proposed. Derived from the Sine map, a delayed Sine map (DSM) is proposed based on the LDM. Then, we substitute the Sine map in the SIMM system with DSM and obtained a delayed SIMM system (DSIMM). Its chaotic performance is analyzed through the phase diagram, Lyapunov exponent spectrum, and complexity. The results show that the delayed chaotic map can generate more complex dynamical behaviors and more random sequences. Hence, we apply the two delayed systems to a novel image encryption algorithm with the permutation-confusion-diffusion architecture. Firstly, to permutate the pixel of the image efficiently, the plain-image is scrambled by using a multilayer of the nonlinear index. Secondly, the image is confused by using the chaotic matrix generated with two chaotic sequences, and then, the ciphertext is transformed into a 1D sequence. Finally, to improve the plaintext sensitivity and facilitate key management, we enhance the sensitivity by applying a novel diffusion algorithm instead of using plaintext-related keystream. The diffusion equation contains the sum of undiffused pixels and the operation of cyclic bit-shift. Simulation results for the gray image illustrate the effectiveness of the proposed encryption algorithm.

“…With the rapid development of mobile internet, social networks, and Location-Based Service (LBS), large numbers of multimedia data [1] with geographical information (a.k.a geo-multimedia) [2], such as text, image [3,4], and video [5][6][7][8], are collected and stored on the internet. As an important data resource, geo-multimedia data is used to support for location-based recommendation, accurate advertising and data search.…”

Mass multimedia data with geographical information (geo-multimedia) are collected and stored on the Internet due to the wide application of location-based services (LBS). How to find the high-level semantic relationship between geo-multimedia data and construct efficient index is crucial for large-scale geo-multimedia retrieval. To combat this challenge, the paper proposes a deep cross-modal hashing framework for geo-multimedia retrieval, termed as Triplet-based Deep Cross-Modal Retrieval (TDCMR), which utilizes deep neural network and an enhanced triplet constraint to capture high-level semantics. Besides, a novel hybrid index, called TH-Quadtree, is developed by combining cross-modal binary hash codes and quadtree to support high-performance search. Extensive experiments are conducted on three common used benchmarks, and the results show the superior performance of the proposed method.

“…Image encryption algorithm involves a variety of alternative or transposition methods to convert ordinary images into encrypted images. For image, video, and other multimedia data with a large amount of data and strong correlation between adjacent data, the chaotic key has a stronger advantage in real-time encryption, so the research of the chaotic image encryption method is attracting more and more attention [54][55][56][57][58][59][60]. PRNG can generate sufficiently long pseudo-random digital key streams that are critical to the encryption of image pixels.…”

In this paper, we propose a method to design the pseudorandom number generator (PRNG) using three kinds of four-wing memristive hyperchaotic systems (FWMHSs) with different dimensions as multientropy sources. The principle of this method is to obtain pseudorandom numbers with good randomness by coupling XOR operation on the three kinds of FWMHSs with different dimensions. In order to prove its potential application in secure communication, the security of PRNG based on this scheme is analyzed from the perspective of cryptography. In addition, PRNG has passed the NIST 800.22 and ENT test, which shows that PRNG has good statistical characteristics. Finally, an image encryption algorithm based on PRNG is adopted. In the encryption algorithm, the optimized Arnold matrix scrambling method and the diffusion processing based on XOR are used to obtain the final encrypted image. Through the evaluation of encryption performance, it is concluded that there is no direct relationship between the pristine image and encrypted image. The results show that the proposed image encryption scheme has good statistical output characteristics and security performance in line with cryptography.
