What is The Balance Between Network Information Shared ( To Authorities) and Personal Privacy.

With criminal acts on the internet on a the rise, most law abiding citizens are happy to find criminals caught online through computer forensics. The underlying question that arises with it is at what cost? The Internet is a well sought after place to get away with crime thanks to the anonymity of its use. To counter this government, F.B.I, and police are seeking ways to improve, trace, and identify the criminals. Although it is good for tracking criminals, many people also feel it encroaches on their privacy.  Rather so, it is a slippery slope on one hand helps to protect society from malicious criminals, on the other privacy goes down and user information is now available for theft.

Many of us have seen forensic shows, and other programs of criminals being caught in action over the Internet and by tracing their computer via of computer forensics. I found an article, that deals with this issue. The article is called "Privacy Preserving Network Forensics" The article deals with the problems associated with Network forensics, and what is going to far on the the regulatory side of network forensics and how to find a balance.  They believe for regulatory purposes physical computing devices should be named and registered, the system should stay intact, so if a case comes later evidence will still remain. Also they wish the that such evidence would not be seen as dismissive in  court, and held as prima-facia. For the Privacy side they believe that the information should be stored and encrypted securely so that it may not be stolen, they also believe that when their digital fingerprint is to be required they be fore-warned, and shown the name their print is attributed to.

We all know that network attribution and privacy are both needed in balance, much as many other things in life. The question to the readers is, in your personal opinion what is the balance needed in this topic? Also how much information would you be willing to share to help keep society safe ? Last is the privacy trade off worth the loss anonymity given to stop criminals?
