Yes - you missed something. It is about intersecting one corpi and NOT
intersecting the other.
This is about what doesn't match - not what does.

Sorry.. how is this different than Naive Bayes filtering??
"Naive Bayes classifiers work by correlating the use of tokens
(typically words, or sometimes other things), with spam and non-spam
e-mails and then using Bayes' theorem to calculate a probability that
an email is or is not spam."

"the set of fingerprints of the test message is intersected with the
spam and ham corpi creating sub sets of matches. Then you do a set
diff both ways (ham - spam) (spam - ham) and whichever side is bigger
wins. Generally it will match on only one side or very predominately
on one side.” — Marc Perkel
You are still looking up words/phrases in a dictionary set, and coming
up with a probability factor of which side it falls on (an application
of Baye’s theorom).
Or did I miss something?

Good luck with your patent application, it should be in the

Not sure how you will deal with the number of ham tokens in spam
messages. Also not sure how much ham will get canned as spam - but
then, maybe people shouldn't be sending each other poetry?

OK - following up on this. I have my provisional patent filed.
I'm still doing development to improve it and working on a
licensing contract. But the license will be based on the Creative
Commons patent with some restrictions added. Basically I want to
get a license fee from the big guys and my spam filtering
competitors. So unless you are in the spam filtering business or
have more than 10,000 email addresses it's not going to cost you
anything.
I'm going to describe the concept here. I'm not going to share my
code because my code is specific to my system and it a
combination of bash scripts, redis, pascal, php, and Exim rules.
And the open source programmers are likely to implement it better
than I have. Basically I'm trying not to put myself out of
business and this new method is a bigger breakthrough than
Bayesian filtering.
Maybe I should call it a new plan for spam?
So - I'm just going to introduce the concept right now about how
it works. Once you know what I'm doing it should be easy to
implement, I had it working in a couple of days and I'm not an
outstanding programmer. One thing to keep in mind is this is a
paradigm shift. It's not about matching - *it's about NOT
matching*. And although it is far better at catching spam, it
best feature is actively identifying good email.
The secret sauce
Suppose I get an email with the subject line "Let's get some
lunch". I know it's a good email because spammers never say
"Let's go to lunch". In fact there are an infinite number of
words and phrases that are used in good email that are never ever
used in spam. And if I'm using words and phrases *never used in
spam* that are used in ham - it's good email. And similarly - if
I'm using words and phrases that are used in spam and *never used
in spam* - it's spam.
So - how do I get a list of words and phrases never used in spam?
I create a list of words and phrases that are used in spam and
check to see if it's *not on the list*.
What I do is tokenize the spamiest parts of the email, like the
subject line, into words and phrases of 1 2 3 and 4 word phrases.
the quick brown fox jumps over the lazy dog - becomes
"the" "quick" "the quick" "brown" "quick brown" "the quick brown"
"fox" "brown fox" "quick brown fox" "the quick brown fox" "jumps"
"fox jumps" "brown fox jumps" "quick brown fox jumps" "over"
"jumps over" "fox jumps over" "brown fox jumps over" "the" "over
the" "jumps over the" "fox jumps over the" "lazy" "the lazy"
"over the lazy" "jumps over the lazy" "dog" "lazy dog" "the lazy
dog" "over the lazy dog"
These tokens are learned as ham or spam and added to sets. I'm
using Redis to do this because it has extremely fast set
operations. I don't know of anything other than Redis that can do
this. So think about Redis as the way to implement this.
A new message comes in. It is tokenized and fingerprinted and
hundreds of fingerprints are generated. Then it's all set
operations. the set of fingerprints of the test message is
intersected with the spam and ham corpi creating sub sets of
matches. Then you do a set diff both ways (ham - spam) (spam -
ham) and whichever side is bigger wins. Generally it will match
on only one side or very predominately on one side.
So I'm not just tokenizing the subject. Also the first 25 words
of the message, the text of links in the message, The name part
of the from address, The header names, the attachment names, the
PHP script if there is one, and various behavior characteristics,
(slow, no quit, no RDNS, number on mime parts, multiple
recipients, etc.)
SpamAssassin is all about matching rules. This is all about not
matching. Not matching allows you to compare to an infinite set
rather than a finite set. So when spammers start misspelling
words to not match the rules, my system catches that and makes
its own rules. The tricks that spammers use not makes it easier
to catch them using this method.
I will post a link to a better explanation later when I write
one. But wanted to let you all know this wasn't just a tease from
some crazy person.
So - here's what I want to see happen.
I'd like to see SA implement this. I will provide a license to
include with it giving most people a free license. sort of like
how Spamhaus isn't free to everyone, but it's in SA. Then the new
method will take off and eventually I'll get a little something
for this.
This new method (I'm calling it the Evolution Spam Filter because
the algorithm mimics evolution.) it doesn't just block spammers,
it decimates spammers. It's not just a treatment - it's the cure.
I hate spam and although I could have kept this secret and made
money having the best spam filter on the planet, I decided I had
a moral obligation to make this generally available. I think this
will save the global economy billions of dollars in recovered
productivity and crime and fraud prevention.
I'm seeing close to 100% accuracy. It is so accurate it's scary
and I think my implementation is crude at best. I think if it
were done right it could even get closer to 100% than I have.
Once you wrap your brain around the concept it's almost scary how
well it works.
The side effects is this is a very fast and simple recursive
learner. What happens is that as people converse by email it
learns more words and phrases about the stuff that people talk
about that are never used in spam. It doesn't have to know what
language you are using, it will learn it on it's own. It's like
having SA with 100 million accurate rules where it write new
rules itself.
I will leave you with that and I'll have more later.
