Abstract: | In existing software registration schemes, the privacy of users is not taken into account and may be in the risks of abuses.
In this paper, we proposed a novel software registration system which can greatly reduce unauthorized use of software while
keeping the privacy of users. To the best of our knowledge, this is the first system that the privacy of users is guaranteed
in software registration. Our system enjoys a modular design and can be implemented by any secure ID-based partially blind
signature scheme. Furthermore, the proposal allows flexible registration information definition. This feature makes our scheme
flexible and practical for more software registration applications.
