One-time installation with traitors tracing for copyright programs
Chu‐Hsing Lin, Chen-Yu Lee · 2001
We propose an innovative software protection scheme by using smart cards. By the use of this scheme, a buyer can purchase software, from a merchant on the Internet, using his (or her) smart card. The bought software, after downloading from website of the merchant, will be protected in such a way that it can only be installed one time in the buyer's computer. Further, a buyer who redistributed copies of the bought software, called a traitor, can be traced from an illegal copy of software program. This scheme strengthens intellectual property protection by preventing from illegal install and use of software programs.
