JPEG HDR is an extension to the standard JPEG File Interchange Format JPEG image file format allowing it to store high dynamic range imaging high dynamic range images . Overview JPEG HDR was created by Greg Ward and Maryann Simmons as a way to store High dynamic range imaging high dynamic range images inside a standard JPEG file. This reduces the file size required to store HDR images compared to other HDR formats such as floating point Tagged Image File Format TIFF and RGBE image format RGBE . It does this by first converting the image into a tone mapping tone mapped version and storing a reconstructive multiplier image in APP11 markers in the same JPEG file. Ordinary viewing software will ignore the multiplier image allowing anyone to see the tone mapped version of the image. Support Software programs that support JPEG HDR s include Photosphere by Greg Ward and pfstools. A Software Encoder was available from BrightSide Technologies formerly Sunnybrook Technologies, acquired by Dolby Laboratories in 2007 . Similar formats Other formats that use a similar idea of storing extra HDR information in a standard JPEG image include CLARITY HDR, XDepth both from Trellis Management and ERI from Kodak .

multiple issues orphan February 2009 context October 2009 The JPEG AVI format uses the Audio Video Interleave AVI Resource Interchange File Format RIFF form with minor changes. Similar to the AVI, the JPEG AVI file format uses the mandatory hdrl and movi LIST chunks. JPEG DIB frames are key frame s, as they all are addressable. Their format is as specified in ISO 10918. The index chunks contain the key frames entries for each data chunk to provide random access for finding JPEG DIB video frames from a large interleaved AVI file. The JPEG AVI format is very similar to the AVI file format. The major differences are as follows 1 The chunk strf contains EXBMINFOHEADER structure members for describing data of the stream format. 2 The Chunk strh contain FourCC FOURCC code JPEG for still images and MPEG for motion images with specific data for initializing the appropriate codec . 3 The Chunk movi or rec contains JPEG DIB data. 4 The Chunk index contains the entries for all JPEG DIB frames as all frames are the key frames. This allows random access to JPEG DIB frames, which was not otherwise available. ref 1.

Jpegx is a freeware application that allows users to hide messages in jpeg .jpg, .jpeg files. This technique is called File Camouflage . It is developed by http www.nerdlogic.org nerdlogic.org and it can be used on 32 bit Microsoft Windows systems. The program was first released on October 30, 2001 and was available for download on http www.nerdlogic.org nerdlogic.org , this site is now offline. Jpegx 1.0.6 JpegX has been reported prone to a trivial encryption weakness. While creating the JPEG that will store the hidden data, JpegX reportedly employs a trivial encryption algorithm. Specifically the embedded encrypted data is appended to the file in a consistent and easily identifiable manner. The data is encrypted using the sum of the ASCII characters in the password as a substitution key. The key is then added with a carry if there is one to the original character, the key is incremented and added to the next character and so on until the process is complete. If no password is used the byte value of the first ASCII character of the data supplied is added with a carry if there is one to 187. The second character added to 188 and so on incrementally until the operation is complete. An attacker who retrieves the JPEG file containing encrypted data may reverse the cipher and reveal the contents with relative ease. This may result in sensitive information disclosure. Information gathered in this way may be used to mount further attacks against the victim. Jpegx 2.0.3 Jpegx version 2.0.3 had a http www.gulftech.org ?node research&article id 00003 04202003 password bypass vulnerability in its wizard. Jpegx 2.1.1 The latest version of the program, Jpegx 2.1.1, was released without a wizard, thereby fixing this security issue.
