JPSEC for Secure Imaging in JPEG 2000
نویسندگان
چکیده
In this paper, we first review the on-going JPSEC standardization activity. Its goal is to extend the baseline JPEG 2000 specification to provide a standardized framework for secure imaging, in order to support tools needed to secure digital images, such as content protection, data integrity check, authentication, and conditional access control. We then present two examples of JPSEC tools. The first one is a technique for secure scalable streaming and secure transcoding. It allows the protected JPSEC codestream to be transcoded while preserving the protection, i.e. without requiring unprotecting (e.g. decrypting) the codestream. The second one is a technique for conditional access control. It can be used for access control by resolution or quality, but also by regions of interest.

Secure JPEG 2000-JPSEC
The Joint Photographic Experts Group (JPEG) has recently rolled out a new still image coding standard called JPEG 2000. This standard integrates an efficient image compression scheme with functionalities required by multimedia applications, such as progressiveness up to lossless coding, region of interest coding, and error resiliency. Security is a concern in many applications, and therefore al...
متن کاملJPEG Privacy and Security framework for social networking and GLAM services
Current image coding standards provide limited support for privacy and security features. An exception is the JPSEC standard, which defines security extensions in JPEG 2000 specifications (part 8). Notwithstanding this shortcoming, the JPEG committee is currently defining a new JPEG Systems standard, which envisages privacy and security support across JPEG family of standards. In this manuscrip...
متن کاملThe Interplay between Compression and Security for Image and Video Communication and Adaptation over Networks
We are witnessing an unprecedented diffusion of multime-dia contents over heterogeneous networks, to desktop and mobile users, with different access bandwidth and quality-of-service requirements and capabilities. Compression is one of the technologies that are making it all possible, by allowing data rate reduction, transcoding, and rate adaptation, which are crucial in the scenario of time-var...
متن کاملFormat-Compliant JPEG2000 Encryption in JPSEC: Security, Applicability, and the Impact of Compression Parameters
JPEG2000 encryption has become a widely discussed topic and quite a number of contributions have been made. However, little is known about JPEG2000 compression parameters and their influence on the security and performance of format, compliant encryption schemes. In this work, a thorough analysis of this topic is presented with a focus on format-compliant packet body encryption as sketched in t...
متن کاملAnalysis of JPEG 2000 Encryption with Key-dependent Wavelet Packet Subband Structures
We analyze and discuss encryption schemes for JPEG 2000 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 analyse encryption approaches b...
