Assessing JPEG2000 encryption with key-dependent wavelet packets

Abstract

We analyze and discuss encryption schemes for JPEG2000 based on the wavelet packet transform with a keydependent subband structure. These schemes have been assumed to reduce the runtime complexity of encryption and compression. In addition to this "lightweight" nature, other advantages like encrypted domain signal processing have been reported. We systematically analyze encryption approaches based on key-dependent subband structures in terms of their impact on compression performance, their computational complexity and the level of security they provide as compared to more classical techniques. Furthermore, we analyze the prerequisites and settings in which the previously reported advantages actually hold and in which settings no advantages can be observed. As a final outcome it has to be stated that the compression integrated encryption approach based on the idea of secret wavelet packets can not be recommended.

Cancelable iris-templates using key-dependent wavelet transforms

“…A further application domain exploiting the wide variety of available wavelet transforms is media security, e.g. providing key-dependency for watermarking schemes [6] or designing lightweight media encryption schemes where the security resides in a secret transform domain [7]. Probably the existing application related most to cancelable biometrics is to provide key-dependency for robust media hashing authentication schemes [14], since biometric templates share many properties with robust media hashes.…”

Securing JPEG-2000 images in constrained environments: a dynamic approach

“…Another lightweight encryption approach has been discussed in [12], where an Anistropic Wavelet Packets (AWP) is used in the compression process. Unfortunately, many of the transformbased schemes are found to be inefficient and insecure [13]. Also, we note that, applying the encryption before the entropy coding may reduce the efficiency of coding, since the statistics of input data is modified.…”

Efficient and secure selective cipher scheme for MIoT compressed images

“…Unfortunately, the transform-based cipher schemes introduce a compression overhead [31] and hence, a communication overhead. Moreover, when using a static key, such schemes may not provide the required security level [32].…”
