IP Authorizer verifies information by accessing Palamida's knowledge base of information on more than 120,000 open source projects. A user's corporate policies also are factored into the equation.

The product is available now, with prices starting at US$15,000 for an annual subscription for small workgroup configurations. It requires 1GB of memory with a single 1.3GHz or dual 500MHz Pentium or equivalent processor, 36GB of hard disk memory and a DVD-R drive. A Web server also is needed; the software runs on multiple application servers.

Black Duck is announcing that its protexIP knowledge base has been expanded recently by more than 10,000 commercial product versions from more than 1,000 companies. Black Duck has added more than 30 million software component signatures, or "code prints," which are comprised of a few lines of code, a code segment or a code tree for use in tracking the reuse of commercial software components.

Black Duck also has incorporated code prints of all source and binary code published by Dr. Dobb's Journal and C/C++ Journal and added them to the knowledge base.

Black Duck also now can recognize code from CPAN (Comprehensive Perl Archive Network).
