Message-digests will protect Rwandan genocide trial interviews

"On Tuesday a group of researchers at the University of Washington
are releasing the initial component of a public system to provide
authentication for an archive of video interviews with the prosecutors
and other members of the International Criminal Tribunal for the Rwandan
genocide. The group will also release the first portion of the Rwandan
archive."

I haven't had a chance to review how they're protecting the hashes,
but will report back as I learn more.  If anyone knows more about
this, the information would be welcome.

As an aside, the OASIS LegalXML eNotarization Technical Committee
has just completed the specification of a protocol called the
"eNotarization Markup Language (ENML)" that has the potential to
play an important role in preserving digital evidence.  While ENML
(pronounced "enamel") also uses SHA-2 message-digests, it adds the
additional protection of symmetric or asymmetric cryptographic key
encryption to protect the hash.

The ENML specification should be available for public comment in a
few weeks; the DRAFT (version 2.2) however, can be found here:
