Having problems with message search?
While LockTight is a very cool feature, it is unlikely to solve
this particular issue. The technology allows users to protect the original
image file (I’ve actually implemented some software that helps hide metadata on
the card using it, for example). Similarly Nikon & Canon have some HW/SW
systems which allow encryption and/or signing of the original raw file.
BUT, once the image has been edited into a more finished product
those enveloping systems aren’t very applicable. The closest might be encoding
as a PDF with protection set. However, that again doesn’t solve the problem of locking
the metadata for a standard TIFF or JPEG unfortunately. As was stated before,
that’s going to require quite a bit more effort from a number of groups.—David Cardinal

"The comprehensive feature set of the D200 -- including the unique
LockTight compatibility and functionality -- will appeal to many
professionals around the world," said Kazuyuki Kazami, General Manager
of Marketing, Nikon Corporation. "Among the D200's target customer base
are organizations that have a real need to protect their content,
demonstrate a chain of evidence and restrict access to confidential or
sensitive image data. Lexar's LockTight system offers us a unique way to
address these requirements from our vertical market customers," he added.
When used in conjunction with a camera that supports the LockTight
system, LockTight CompactFlash employs a unique strategy to protect
data, and, as a result, LockTight cards are always "locked." A
computer
or camera cannot read or write data to/from a LockTight card until a
critical authorization process takes place between the LockTight card
and the host computer or host camera. This authorization process is
where the 160-bit HMAC SHA-1 hash algorithm is employed.
