Will JPEG's Next 'Privacy and Security' Features Include DRM? (davidgerard.co.uk)
David Gerard has concerns about the Joint Photographic Experts Group (the ISO working group handling the JPEG standard for image compression). "They seem to think they can advance the cause of DRM for JPEG images...with a bit of applied blockchain." He bases that charge on the fact that the JPEG committee organized a special session on blockchain, and then created an ad hoc group to define use cases. After six months' collaboration, the group has produced a white paper -- "Towards a Standardized Framework for Media Blockchain" -- as announced in the press release following the 80th meeting in July. The Executive Summary declares, "Fake news, copyright violation, media forensics, privacy and security are emerging challenges for digital media. JPEG has determined that blockchain technology has great potential as a technology component to address these challenges in transparent and trustable media transactions... [T]he standardization committee continues to work on improving various components of the standard. This includes incorporation of new technologies addressing current challenges related to transparent and trustable media transactions such as JPEG Privacy and Security."
"JPEG Privacy and Security" is described later in the paper. "JPEG Privacy & Security aims at developing a standard for realizing secure image information sharing, capable of ensuring privacy, maintaining data integrity, and protecting intellectual property rights."
That is, "Privacy and Security" is a euphemism for Digital Rights Management (DRM) in JPEG.... Chair of the group Dr, Frederik Temmermans stressed to me that "JPEG is not working on DRM in particular but on a more generic framework that supports privacy and security features." But DRM is very much a significant part of this. -

Microsoft's HD Photo to Become JPEG Standard?
Mortimer.CA writes "Ars Technica is reporting that Microsoft has submitted their HD Photo to the JPEG committee: 'Microsoft's ongoing attempt to establish its own photo format as a JPEG alternative (and potential successor) took another step forward today when the JPEG standards group agreed to consider HD Photo (originally named Windows Media Photo) as a standard. If successful, the new file standard will be known as JPEG XR.' Microsoft has made a 'commitment to make its patents that are required to implement the specification available without charge.' While JPEG 2000 exists, HD Photo has several advantages (not the least of which is a lot less CPU power is needed). Is this a big of an issue as ODF/OOXML?" -
State of the JPEG2000 Standard?
ehb asks: "With all the (r)evolutions going on in networking (IPv6), video (MPEG4/H.264) and audio (MPEG4 AAC), I was wondering what happened to that big image compression promise of some years ago: JPEG2000. According to the official JPEG2000 page, although the entire standard not is completed, the important parts are, which would allow JPEG2000 to function as a still-image replacement for the old JPEG! I have seen lists of software programs that implement (parts?) of the JPEG2000 specification, but missed the important ones (web browsers, etc). There even exists an Open source implementation of the codec, so what is holding everything back? The benefits over normal JPEGs are huge, so can someone shed some light on the hold-up?" Back in April of 2002, JPEG2000 was "coming soon", and it was touted as being the "the future of imaging", but after that the hype seems to have dried up. What happened to this promising specification? Did another format surpass it (PNG, perhaps)? -
JPEG Committee On The Ball, Seeks Prior Art
Sangui5 writes: "It seems as if the JPEG Committee has noticed the recent patent fuss, and is working on the prior art angle. Good to know that even though there's a new standard, the committee is standing by their previous work." -

JPEG2000 Coming Soon
Sonny writes "In a few months time, internet users will be able to make use of the JPEG2000 standard which, its developers claim, enables web graphics to be downloaded much faster than is currently possible. This will not only make graphics-heavy web pages easier to download, it will also preserve image quality. The JPEG standard compresses image files which are then transmitted across the web faster than uncompressed files. Now, researchers at universities around the world have developed JPEG2000, the next-generation image-compression technology under the auspices of the International Standards Organisation. It is the first major upgrade of the standard since it first appeared in the early '90s. What is also important about the technology is its ability to send files without loss of data, which is not the case with current JPEG files. To take advantage of a JPEG2000, web browsers will need a Plug-In for either Internet Explorer or Netscape browsers. These free plug-in's are expected to be available later this year. The extension for the new files will be ".jp2"." -

JPEG2000: Is It The Future Of Imaging?
LISNews writes: "EE Times has a cool story on the pending JPEG2000 standard and how it will change what we see on the Web. They are already thinking wireless: 'The killer app for JPEG2000 is a handheld device combining both Internet applications and wireless access.'" They're also thinking about migration from current formats, smooth degradeability and -- nice to hear -- Open Source acceptance. Try JPEG's own JPEG2000 page for more information and links.
