According to ipoque's study, only two technical solutions are realistically open to businesses: hash-based identification and active monitoring.
In a peer-to-peer network, every file is identified by a hash (unique ID) of some kind, Schulze explained. Files containing copyrighted material can be detected and therefore filtered out from transfers.
While hash-based identification is feasible, affective and affordable (ipoque estimates the cost at approx. 1.5 Euro per user), network operators are simply not interested in installing this additional equipment, said Schulze.
Alternatively, Schulze recommends active monitoring of copyright infringement and penalizing those who violate against copyright laws.
It's less intrusive, doesn't require installation of equipment, and more cost effective because it runs anywhere there is an Internet connection, he said.
