Deep Packet Inspection (DPI) involves the use of network equipment to intercept, examine, modify, restrict, or copy the content of data communications on the fly. It serves many purposes from analyzing network traffic to being used by law enforcement or spy agencies for surveillance. DPI potentially allows ISPs to collect and analyze Internet communications of millions of users simultaneously. The technology has come under fire before and is again raising serious privacy concerns about the alarming potential for abuse. Will we really want marketing based upon deep packet inspection?”]
