ABSTRACT:
Improved techniques for implementing Network Copy Protection for database programs are disclosed. The techniques can provide Network Copy Protection across various platforms and/or connection protocols. Accordingly, the database programs can detect unlicensed use of the software even when different platforms and/or connection protocols are used by two instances (software copies) of the same database program. When unlicensed use of software is detected, access to data can be denied. As will be appreciated, in addition to supporting more conventional communication protocols, more prevalent connection protocols can be supported.
