There is some indirect evidence that criminals might already know about the vulnerabilities in the systems, Mr. Blaze said, because of "unexplained gaps" in some wiretap records presented in trials. Those old enough to remember Watergate will remember a very significant 18-minute gap.
I think he is referring to gaps in the records, like taped calls Tuesday, taped calls Wednesday, strangely no call on tape on Thursday, taped calls on Friday, etc. If the tap recorder can be shut off with a signal, you would not encounter "dead space" on the tape for a duration of time. Instead you would have a premature end of that session. Now, it would be really troubling if another signal could be sent to reactivate the recorder (which I find likely to be possible). That way you could let yourself get tapes, but silently exclude a section for a minute where you discuss devious matters. The tape would appear to be complete (if it is autonomously recorded. If someone listens in a logs the time/duration with a stop watch, the jig would be up). So, if you can manipulate the tape so that it *appears* to be in order, but lets you pause the recording at will, you have plausible denyability (or whatever the correct term is). *That* is way more scary than an known premature end. Cheers, Frank -- It is said that the Internet is a public utility. As such, it is best compared to a sewer. A big, fat pipe with a bunch of crap sloshing against your ports.
