Internet Research Task Force,
Anti-Spam Research Group,
Greetings. I have some ideas to prevent spam. A number of heuristics include
increasing the computation required to send and receive an email, for example
one to a few minutes of computation per email on desktop computers.
One example of a heuristic, from that category, includes the use of a random
number generator, seeded or salted with a combination of the sender's email
address, the recipient's email address, and the date and time of the sending of
the email. Then, in the described example, some amount of computation,
measurable in minutes on a desktop computer, churns a stream of bits from the
random number generator, in a buffer the size of which can be obtained from the
size of the email, and with those bits in that buffer then utilizable by other
heuristics. The recipient of an email can, with the sender's address, their
own email address, the date and time of the sending of the email, and possibly
other data, seed or salt an identical random number generator, churning a
stream of bits, with an indicated amount of computation, measurable in minutes,
to obtain the same bits in an identically sized buffer.
By increasing the computation required to send and receive email messages, for
example measurable in minutes of desktop computation, desktop graphics card
computation, spam can be reduced as spammers would have to compute, per letter,
per recipient, per email sending event, as described. In addition to, possibly
in combination to, that category of heuristic, increasing the computation
required to send and receive emails, the digital signing of email messages can
be of use to preventing spam.
In addition to countering spam, I have observed some interest, in the
scientific community, with regard to discussing the versioning of and
advancement of email protocols, modernizing email-related computer networking
protocols.
Kind regards,
Adam Sobieski
