Hey Grant et al;

Giggle, well I am glad to hear from someone who actually has to deal
with these things. I have seen a lot of things that people go running after
as the next big thing in some industry and 3 years down the line it causes
real trouble. Also I am sure there a lots of security products that were
released during the dot-com boom by companies with clever names
like "Security  Solutrions" and at least one manager somewhere thought
it was the latest and greatest. and bought it. and now someone is caught
with it and "Security Solutions" went bust in the dot-com bust.

I have looked at the RFID stuff amd all the plans worked for it, including a
whole set of PR campaigns to calm public privacy fears. What I wondered
is why there was so much effort being exerted to track say a can of coke or
a pen or something like that. Some of the software looks very complex and
it looks like no way is it plug and play and it looks like something that will go wrong way too easily. It is obvious at ther local drug chaiin that the computer is not given the correct price many weeks in a row. That seems pretty simple to do. If they can't get that right how are they going to get something more complicated right. I might trust librarians to try to get things right, but some of the people
in the local stores its one more hassle for them.

Have Fun,
Sends Steve

Just a bit more info the RSA pin cards. I deal with these quite often.
The guy "cjs" is slightly mistaken. The pin cards are really 2-factor authentication. The card itself uses an algorithm within the card that the RSA server understands, or can decode. The other factor is the pin that the client (human) remembers. So if the pin card gets stolen it can't be reused. Sort of like an ATM card, but more sophisticated. In reality the whole thing is a big pain in the ass to setup and implement. I think RSA has come up with somewhat better schemes I just hope they don't come my way too soon. The pin method is a big pain in the ass to setup, and given the new security stuff, I don't even want to look at anything new.

eh?, yeah, right?;) <====said with a sneer (giggle;)

More seriously I was looking to RFID systems vis a vis the privacy
orries of such and such systems and I wondered what would a store,
ora library want with something that with effort could tell you everywhere
it has been. Now I admit when I have misplaced two books I really
somedays want a "magic wand" to find them.

The other problem is I have seen my local library try to handle its
security concerns and somethings seem reasonable to me, many seem
being a bit overcautious after being burnt.  I know the legends involved,
when I mention I am trying to solve some problem I am told I just need
an 11 year old to do it for me, as if they are pixies with magic power.
Getting your staff which is dedicated in the case of the library, but which is dedicated but which several techoquestioning? (giggle trying to be polite) people on it, but which is sensitive to privacy concerns. Versus the people at the Long's Drug Chain (Medium Sized US Drug Chain) where there is a big taa-doo at the register to check everything out whenever I bring in an item
that I was overcharged $3.00 for. I look at some of the more elaborate
security systems that merchants have been sold as being good and I am ready at least emotionally to join the "number of the beast" worry-worts. I hope the Long's main office when presented with a new security plan looks at it
and laugh's and says it is too expensive.

But I am sure that someone has told some ubermanager far away from Watsonville California that "Your Shrinkage Problems will dissappear if you install our $5MEgabuck system....which if you look at it per item, it is not that expensive...." Of course the guy selling it is far distant again from the techies who produced to earn their daily bread to pay for living in the $1000US/mo apartment. The salescreature thinks the idea of selling random numbers at $25.00 for a couple hundred is a good thing. I mean they say: "Those are magic numbers they are produced by complicated
software written by people who are so bright....." You get my drift.

P.S. The "they lock when you take them beyond the parking lot " shopping carts have become great playtoys for kids in the neighborhood who like to overpower them and
hear them beep as they drag it along like a relcalitrant puppy.

RSA has been doing PIN cards for ages...I don't get the hangup on
SmartCards vs "plain old" something you have/something you know two factor
as I understand it a "PIN Card" is a card with an EEPROM on it that
contains a PIN.  Possibly encrypted but its the same effect as any other
file. The host decides if the PIN matches.

The RSA SecurID system is a hardware token that generates a new number
every minute using a sequence generator and a seed that is effectively
a shared secret between the hardware token and the authentication
server. You take the current minute's number and, usually, some other
authentication information (such as a PIN or password) and pass both
of those back to the authentication server, which will then determine
whether the authentication is valid.

It's a bit expensive, but it works ok.

RSA also sells "software tokens" which are the same thing, but as
software that runs on a PC or handheld. This is particularly expensive
for what you get, since the token is easily copied from the device, with
no indication that it's been stolen. (At least with the hardware tokens
you know when it's been stolen.) And it's also quite expensive: they
charge $25-$80 for a "1 year" software token. I wish I had the gall to
sell large quantities of 128 bit random numbers for $25 each.
