  • Business Idea: Portable TEMPEST Glass Enclosure

    From warmfuzzy@700:100/0 to All on Fri May 15 23:25:23 2020
    I've had a reoccuring business idea which deals with having TEMPEST glass enclosure that you can slide a computer monitor into, the system would be a very simple Plug'n'Play idea that has a large upper portion with a cavity in
    it that the LCD/Flatscreen monitor sits in. The bottom of it would also be glass, TEMPEST-resistant glass, that fits into the upper portion. This would be a very inexpensive alternative to the $5 Grand monitors that are only TEMPEST level 1. This could be made from between $50 and $200 and would be modular in the sense that any brand of monitor would fit inside it.

    For those of you that are unfamiliar with TEMPEST technology it is an
    emissions security specification that details reducing compromising computer equipment's radiation so that your neighbors can't pick up the emissions and reconstruct what is being displayed on your screen. This was a mahor problem back in the 80's and mid 90's when the normal monitor was CRT (cathode ray tube). I'm not sure how serious of a threat it is today, but its probably not completely gone from the tricks bag of the intelligence community.

    Ha,
    That reminds me of me trying to pick up my brothers CRT of his Schneider PC back in the early 90's using an analog TV tuner :) never was really
    successful

    One of my callers back in the day, M.L Shannon (never knew his real name) wrote a book called "Don't Bug Me" that had some interesting surveliiance ideas. It's a bit out of date, but worth a read.

    I have an advance copy he gave me here somewhere.
