A new method for software program protection by information sharing and authentication techniques using invisible ASCII control codes is proposed. A scheme for sharing a secret source program written in Visual C++ among a group of participants, each holding a camouflage program to hide a share, is first proposed for safe keeping of the secret program. Only when all the shares hidden in the camouflage programs are collected can the secret program be recovered. The secret program, after being exclusive-ORed with all the camouflage programs, is divided into shares.
