Anyone who has seen outlook revocation requests knows to look in their inbox for an embarrassing e-mail. Yet, this doesn't mean that distributed revocation is an impossible problem: on the contrary, I think it's getting more important as people realize how much online information is out there. In a sense it's the "real" online privacy (instead of group access control that Facebook and Diaspora want you to think is privacy).
- joe_the_user 16y agoYet, this doesn't mean that distributed revocation is an impossible problem: on the contrary, I think it's getting more important as people realize how much online information is out there. A moments thought should show that distributed revocation is inherently impossible except in an air-tight "trusted computing" environment. Such an environment may be possible to construct but that construction has been shown to quite difficult at the least (especially resulting in systems with exponentially inferior performance, turning O(1) problems into O(n^2) problems, "The Xanadu Project" had conceived of the before CERN but floundered on this problem, etc). Moreover, such an environment is so undesirable that I, along with quite a few others, would actively work to prevent it coming into existence. "The Right To Read" etc... ...and of course how important some unspecified group of people are coming to see distributed revocation as being itself has no relation to how possible it is.
