[Wired] Military’s New Plan to Weed Out Counterfeits: Plant DNA - Page 2

post #11 of 15
Two words which seem to have dissapeared from industry:

QUALITY CONTROL

Check what you are getting. Test It. Make sure it is what it says it is and does what it says it does.


But no..... Us being human would rather spend millions on new research and fancy pointless surveys to findout the best way to serve a purpose.... A purpose which has either already been fufilled in the past or is just too easy to solve.

How does post-manufacturing QC tell me if I have a genuine non-counterfeit item when I buy it? How do I know that I'm getting genuine parts when I order them, and how am I able to verify this without having to install and test every piece of hardware that I get?

edit--The problem is that it becomes incredibly expensive in terms of man-hours to test each component as you get it, and it also means instrument down-time for whatever you're putting it into. It makes much more sense to have a non-invasive method to verify authenticity. You can point a laser beam at an item, collect data on it and verify authenticity within seconds, rather than installing, test, discard.

But what about pharmaceutical pills that you can't easily check if it's authentic just by looking at it, and testing it would be an invasive way (i.e. using one or some of the pills).

How long does it take to sequence a strand of DNA?

If they're not sequencing the DNA every time, isn't this just one more form of visual inspection that can be fooled with the correct color dye?

It's probably some sort of spectral analysis, looking for one or multiple signatures--I don't think it's doing a sort of genetic sequencing. One type of DNA will have a specific spectral characteristic while another strand will have a different spectral characteristic (probably makes it more feasible to tag many things with a variety of strands, so you know that "this" came from "that" place and not somewhere else, for example).

The issue isn't whether or not the Military needs to be able to authenticate supplies quicker. The issue is how you do it. There is nothing in the article saying it would be incredibly slow or expensive. If the benefits will outweigh the costs, that defines it as a good plan unless something better is available (doubtful at least in terms of security, possible in terms of price/efficiency).
