Hello Dwayne, You haven't mentioned so I will assume your software will be running on MS platforms and optimized for this.Since you are looking for a strong licence methodology, you have to develop it your self.And this is something you can not find here.This is a whole different area of profession and information which is going to solve your problem is some sort of commercial data. > > IF someone decides that they want to share their copy with others ** > > AND ** if their copy somehow winds up in the wild, the person > > responsible can be easily tracked. This is completely wrong. > Like Jake said, whatever software you add some kind of protection to > it will be cracked. This is wrong too.Although, not completely. In my professional experiences none of the software protection techniques have been %100 secure.In this point , you have to be more creative and come up with a new protection hardening method.Since I don't know the details of your project and the code , it is not appropriate to make more comment.But counting on my 8 years of experience, I can say that I developed protection techniques which did really good job and still are in use.You have to developed a hardening module so unique.if I don't have the notes and the source codes of my techniques,at some of them, I may probably stuck somewhere in the code and not able to crack it even now.But, depending on your softwares functions,if someone or a company hires an experienced security engineer or a professional software reverse engineer -as an abstract a person who makes living from this job- to crack your code and -in theory- eventually he is going to crack it.This is how things work.Theoritically none of the software are %100 protected.Most of the underground cracking groups have limited skills and background theory on software protection.And according to the statistics softwares which are cracked during the past 8 years use public and known protection techniques.Another reason for this is that usual programmers do not have strong security perspectives,they only do what they are focused on.This is why IT and IS are different communities. I hope you got my point.If you think your software is worth to invest more,you can contact me.
