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:
“Good-bye, proud world! I’m Going home;
Thou art not my friend, and I’m not thine.
Long through thy weary crowds I roam;
A river-ark on the ocean brine,”
—Ralph Waldo Emerson (1803–1882)
“Along the iron veins that traverse the frame of our country, beat and flow the fiery pulses of its exertion, hotter and faster every hour. All vitality is concentrated through those throbbing arteries into the central cities; the country is passed over like a green sea by narrow bridges, and we are thrown back in continually closer crowds on the city gates.”
—John Ruskin (1819–1900)
“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.”
—William Butler Yeats (1865–1939)
