“…Norcen and Uhl [43,44] have investigated the usage of random permutations applied to wavelet coefficients within the JPEG2000 coding pipeline. Both confidential and transparent encryption can be implemented by applying permutations to the appropriate subbands, however, one has to keep the inherent security concerns regarding permutations in mind (e.g., vulnerability against known plaintext attacks).…”

Image and video encryption has become a widely discussed topic; especially for the fully featured JPEG2000 compression standard numerous approaches have been proposed. A comprehensive survey of state-of-the-art JPEG2000 encryption is given. JPEG2000 encryption schemes are assessed in terms of security, runtime and compression performance and their suitability for a wide range of application scenarios.

“…Hybrid pay-TV technology has extensively used line permutations (e.g. in the Nagravision / Syster systems), many other suggestions have been made to employ permutations in securing DCT-based [11,12,11] or wavelet-based [7,13] data formats. In addition to being very fast, permutations have been identified to be a class of cryptographic techniques exhibiting extreme robustness in case transmission errors occor [9].…”

Abstract. Chaotic mixing based encryption schemes for visual data are shown to be robust to lossy compression as long as the security requirements are not too high. This property facilitates the application of these ciphers in scenarios where lossy compression is applied to encrypted material -which is impossible in case traditional ciphers should be employed. If high security is required chaotic mixing loses its robustness to compression, still the lower computational demand may be an argument in favor of chaotic mixing as compared to traditional ciphers when visual data is to be encrypted.

“…Wavelet based partial image encryption [3] is also proposed for digital image security. In [4] the impact of using random coefficient permutation is investigated to provide confidentiality to wavelet based still image compression pipelines. In [5], [6] Arnold cat map and in [7] logistic map has been proposed for encryption of images.…”

Abstract-This paper proposes an efficient method for encryption of digital images using an adaptive algorithm. According to the proposed algorithm the image used was segregated into significant and non significant blocks. For making the level of security different for different blocks, total and partial encryption has been utilized for the significant and non significant blocks respectively. Spatial as well as transform domain for the significant and non significant blocks respectively are used in this proposed method. The final encrypted image reflects the efficacy of the proposed algorithm. A comparative study between the conventional approaches of spatial and transform domain for the encryption of the image with the proposed encryption algorithm reveals the superior performance of the proposed algorithm. The experimental results suggest that the decrypted image is of excellent quality and signal to noise ratio is maintained well within the limit. The computational time utilized is very less as compared to the conventional approach, which suggests the enhanced overall performance and makes it suitable for high speed online applications.Index Terms-Arnold catmap, image encryption, logistic map, spatial and transform domain.
