A New Image Block Encryption Method Based on Chaotic Map and DNA Encoding

Chaotic image encryption algorithm using frequency‐domain DNA encoding

“…The corresponding correlation values in other directions are Table 5. Moreover, if compared with the results in [9,13,27,28], the proposed algorithm shows better correlation values. For all of the sample images, the average values of correlation of the cipher images in all directions are −0.0011, −0.0047 and 0.0032, respectively, which implies no correlation in the corresponding cipher images.…”

Systematic Survey on Visually Meaningful Image Encryption Techniques

“…In this, a secret image was encrypted by using traditional encryption and dynamically embedded through IWT. Some authors presented salient regions encryption based VMEI techniques [30,31]. The salient regions of an image contain useful information.…”

“…In [30], the salient features were detected and encrypted using a parametric switching chaotic system-based image encryption algorithm. Sun et al [31] presented a method in which salient regions were encrypted using a chaotic system and Deoxyribonucleic Acid (DNA) coding. In both the methods [30] and [31], DWT was used for embedding the encrypted image into a reference image.…”

In both the methods [30] and [31], DWT was used for embedding the encrypted image into a reference image. Advantages of the DNA include enormous storage, massive parallelism, very low power consumption and high speed [32].…”
