Hello you all.

I am in a hobby project and would need a easy-to-use Java class or
component I can use more or less out of the box in my project for
simple text recognition. I want to compare one or more pieces of text
with one or more pieces of text to get some sort of indication if (1)
the information is auto-generated and (2) the writer is the same
person.

Do not look for a high probability, have from a small to medium amount
of text material to work with, just need something that can raise a
red flag and merit human attention in some cases.

Any hints on where I should go looking?

As a small side-question, I'd also appriciate info on similar open-
source class/component to scramble (or rather perform simple
encryption).

/Thanks
