Crowds
Crowds is a proposed anonymity network that gives probable innocence in the face of a large number of attackers. Crowds was designed by Michael K. Reiter and Aviel D. Rubin and defends against internal attackers and a corrupt receiver, but provides no anonymity against a global attacker or a local eavesdropper (see "Crowds: Anonymity For Web Transactions"). Crowds is vulnerable to the predecessor attack; this was discussed in Reiter and Rubin's paper and further expanded in "The Predecessor Attack: An Analysis of a Threat to Anonymous Communications Systems" by Matthew K. Wright, Micah Adler, And Brian Neil Levine. Crowds introduced the concept of users blending into a crowd of computers. Provide users with a mechanism for anonymous Web browsing. The main idea behind Crowds anonymity protocol is to hide each user's communications by routing them randomly within a group of similar users. By Crowds protocol a corrupt group member or local eavesdropper that observes a message being sent by a particular user can never be sure whether the user is the actual sender, or is simply routing another user's message.

Famous quotes containing the word crowds:
“Although crowds gathered once if she but showed her face,
And even old men’s eyes grew dim, this hand alone,
Like some last courtier at a gypsy camping-place
Babbling of fallen majesty, records what’s gone.”

“I do not find
The Hanged Man. Fear death by water.
I see crowds of people, walking round in a ring.
Thank you.”

“The long high tent of growing and making, wired-off
Wood tables past which crowds shuffle, eyeing the scrubbed
spaced
Extrusions of earth....”
