Intellectual Property OPM (formulas)

A customer asked us for the best practises in Intellectual Property (IP) within OPM manufacturers. Their target is:

• Avoid an easy, massive gathering of sensitive data (formulas, batches)
• Ensure only a restricted number of people has regular access to data
• Protect data above and beyond the standard security level already applied

The customer is already using the Formula Security, but we are looking for other kind of IP security which go beyond the standard Oracle Security. Think of private network, database security, etc. Any kind of information or idea is welcome.

Thank you very much for your help.
