ABSTRACT:
A system for providing protection against pirating of software product or products or any other digital information being sent over the Internet, or by physical means, to a computer system. The system generates a set of parameters associated to the authorized user's system and uses those parameters to form a value. Then the invention encrypts that value leaving a set of encrypted forms of the value. The set of encrypted values is then sent to the user's system. The original set of parameters are again generated on the user's system and used to decrypt the set of encrypted values sent to the user. If the result of this decryption yields a minimum number of identical values, a quorum is deemed reached, and the invention allows the user to access to the software product. The software product also may have been encrypted using the initial formed value. Thus, if the quorum is reached, the resultant most identical value will be the initial value formed by the invention, and will then successfully decrypt the encrypted software product.
