Pre-PMA 2004: Canon today announced the latest version of its Data Verification Kit, the DVK-E2 kit is designed to deliver validation of an unmodified original image from a single camera body. This kit is aimed at law enforcement, insurance, news and other such agencies and can detect single bit discrepancy in modification of an image since it was taken. The new kit is much smaller than the old and uses a unique SM (secure mobile) card which is the same size as a Secure Digital card. The card reader connects to a computer USB port (only Windows 2000/XP compatible at the moment).

Press Release:

Canon validates digital images with DVK-E2

Amstelveen, The Netherlands, 29 January 2004. Canon, a leader in photographic and imaging technology, today releases the DVK-E2. Designed to work with the EOS-1Ds and new EOS-1D Mark II D-SLR cameras, the DVK-E2 provides the facility to prove that images taken with the EOS-1D Mark II have not been altered, tampered with or manipulated in any way. The DVK-E2 is the successor to Canon's DVK-E1 and will work with both the EOS-1Ds and the EOS-1D Mark II.

Recent well-publicised cases involving image-tampering by news agencies have identified a strong need for a system capable of verifying the originality of digital photographs. Without such a kit it is impossible for an agency to identify whether or not a given image has been enhanced or manipulated.

ISO certification

With the capacity to detect the slightest (single bit) discrepancy, the DVK-E2 kit is expected to be popular amongst law enforcement, insurance, news and other agencies that have a need to verify the legitimacy of digital images. Canon is applying for ISO 15408 certification (evaluation criteria for IT security) for the Data Verification Kit to further validate its application. The acquisition of ISO 15408 certification will give international recognition to the originality of images shot with the EOS-1D Mark II or EOS-1Ds whilst in data verification mode.

How it works

The kit consists of a dedicated SM (secure mobile) card reader/writer and verification software. When the appropriate function (Personal Function 31) on the EOS-1D Mark II or EOS-1Ds is activated, a code based on the image contents is generated and appended to the image. When the image is viewed, the data verification software determines the code for the image and compares it with the attached code. If the image contents have been manipulated in any way, the codes will not match and the image cannot be verified as the original.

Compact and easy to use

The SM cards used with the kit are the same size as an SD card. The tiny SM card reader/writer is barely bigger than the cards it takes. It draws the power it requires from the USB port of the computer to which it is connected. The software is Windows 2000/XP compatible. Up to 100 images can be evaluated simultaneously, simply by selecting the images and clicking 'Verify'.

The kit supports English, German, French, Spanish, Italian, Japanese and Chinese languages.
