Title: Re: Legal Notice on RFC3161 Uses and their possible infri

Folks,

Attached is the abstract for Todd's latest patent in this area, which he alluded to in his posting to this list.

Since RFC 3161 makes no mention of using time stamp info for access control, the likelihood of this RFC infringing seems questionable to me, but that, of course is not a legal opinion.

If Todd wanted to follow established IETF procedure, as per RFC 2606 he should have sent this message to ietf-ipr@xxxxxxxxx In fact Todd did post such a message for his previous IPR assertions in this general area, but maybe he didn't feel that such posting had sufficient dramatic effect.

Controlling access to stored information based on geographical location and  date and time

Abstract

Access to stored information by a user is controlled by comparing an actual  geographic position and/or an actual date/time with a geographic region  and/or a date/time interval within which access to the stored information  is authorized. The actual geographic position where the stored information  is located, and the actual date/time can be determined, for example, based  on signals received at a receiver supplying reliable position and time  information, such as a GPS receiver. Access to the stored information is  authorized if the actual geographic position and/or date/time falls within  the authorized geographic region and/or date/time interval. The position  and date/time information supplied by the receiver may be  cryptographically signed and encrypted.
