Digital calls easier to intercept/record than analog?
I would argue no.
Quote: As an increasing number of phone calls are being routed via the Web, through Web-calling services, they are becoming easier to record than traditional phone calls, as they are in a digital format.
Yes and no: Digital calls to digital storage is easy, yet most calls now and in the future will be peer-to-peer and encrypted. It's so with Skype, and can be so with SIP, H.323 etc, so why not in all future protocols? It's the best way to spread out the load and secure you can't be eavesdropped. In Skype's case it's also a very good way to hide the technology as such (creating a walled garden where there previously was none).
This also means archiving of calls will be very expensive due to the infinite number of peer-to-peer links and the number-crunching needed to decrypt all the calls. I understand if governments are worried about that, but as an individual I'm of course happy as a lark.
Archiving Phone Calls? Why Not; It's Cheap
