Get a Nikon D2X or D200
"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.
