Abstract
A protection subroutine with a unique reference code is emplaced in a protected software package. The package also contains a validation program. The protection subroutine and validation program connect with an ESD and both the ESD and the program communicate with a secure computer. Upon receipt of inputs of the software serial number and reference code and the ESD identifier, the computer generates a validation code which causes the protection subroutine to command execution of the protected software by its hose computer.
