ABSTRACT:
A software protection apparatus and its protection method are disclosed. The software protection apparatus includes a storage unit and a processing unit. The storage unit has a program area and a data area. The program area is used to save an executable. The processing unit generates a reference pointer based on internal information of the executable, and the reference pointer then is saved to the program area or the data area. The processing unit then generates an algorithm based on at least one characteristic of the executable to save the algorithm to a specific position of the program area or the data area through the reference pointer, and employs the algorithm to perform an encoding action for the executable to generate a wrap program that is saved to the program area. When the wrap program is decoded, the reference pointer is obtained through a restore program to take the algorithm out. The wrap program then is restored to become the executable by using the algorithm.
