The Jargon File (version 4.4.7, 29 Dec 2003):
1. [Originally from the Xanadu hypertext project] A tumbler is a magic
cookie generated as part of a record or message to give it a unique
identity. Usually a tumbler includes an encoded form of its creation date,
but if a software system has more than one concurrent process that could
generate tumblers it must also include an encoding of the process ID. If
tumblers will be shared across multiple network hosts, they must also
include the host name or network address. Tumblers often include a hash of
the rest of the message or record content so that it is possible to verify
the correctness of the data the tumbler is attached to.
2. Variant text added to spam instances (often in the Subject line) to make
them unique. This kind of tumbler is used to defeat schemes that check an
exact hash of an incoming message against known spam signatures; it also
compromises some kinds of statistical spam recognition.
