TLDR
An image encryption algorithm in frequency domain using a chaotic permutation is presented, which shows that the cipher-image was robust to the image processing operation, and the decrypted images can be still recognized well.Abstract:
Images can be encrypted in spatial domain, frequency domain, or both. Most of the image encryption algorithms operate in spatial domain. Encryption in frequency domain has an advantage of being resistante to many image processing operations. This paper presents an image encryption algorithm in frequency domain using a chaotic permutation. Because of the images represented in JPEG format, then to increase robustness to the image processing operations, the plain images are encrypted in blocks 8 × 8. After an image is encrypted, the cipher-image was modified by some common image processings. The experiments shows that the cipher-image was robust to the image processing operation, the decrypted images can be still recognized well.read more

TL;DR: A robust color image encryption technique is proposed that uses Discrete Cosine Transformation (DCT) and a diffusion operation first applied in spatial domain and then a confusion operation is applied in frequency domain, and its result has been compared with existing technique and shows that the encrypted image is enough robust against any types of attacks.
