P0149 XML compliant Signature GeneratorKa-Po Lam As individual parts of the JPEG 2000 (J2K) standard, Part 8 (JPSEC) deals with such security issues as authorship and ownership of the image data, whilst Part 9 (JPIP) defines how interactive applications between a client and server can be created. Using the metadata stored within a data stream, the aim of this project is to design a prototype generator which can permit image 'signatures' to be generated and (similar to the concept of watermarking) to be exchanged across image-centric engines (eg. image databases) in a networked/distributed environment. By adopting a suitable pattern recognition methodology, these signatures are expected to offer increasingly important transactional information - licensing restrictions, client details customer ..etc, in supporting security-enforced communications of image-based information in a standard compliant XML environment.
