Software piracy is a severe problem for a software company,and optional piracy usually brings a software company serious consequence.Many pirates are simply duplicators,and they purchase only one authorization,and think acceptable the duplication of the software on many other computers.In order to avoid software piracy,soft dog is a good choice.The software could not be used unless an authorized softDog is inserted in the computer.This method could prevent random duplication of the software,so that the legal profit of software companies can be guaranteed.In combination of softDog with cryptography,a softDog is designed,and the HMAC technology is employed to ensure the security of the software.
