Another difference between Caller ID and ANI is that Caller ID returns the number you are calling from unless blocked or from certain lines that, for example, do not have an incoming telephone number. ANI returns the billing number. For most residential customers the two will be the same, for corporate accounts or for people with more than one line, there could be only one ANI for all the phone lines. > ANI *cannot* be blocked by dialing *67. true. at least as currently implemented. > There would probably be another issue involved since the only > way they could keep from delivering your number would be to > disable ANI on calls; assuming this was even possible, it > would trigger faults and other problems associated with ANI > failure. Since ANI exists so that LECs (long distance companies like AT&T or MCI) can properly *bill* calls, there is no reason that ANI has to be provided to any recipient of any call, 800 number or regular number like 213-572-3467. (I have no idea what that number is or even if it is a working number). If no ANI were delivered to the recipient of a call, billing could still be done. (Note: Even 900 numbers do not need ANI. They could be required to negotiate a payment method at the time of the call.) Further, I do not buy the argument that just because someone pays for an 800 call, they deserve to be able to invade my privacy. Sure, recipients often like to purchase this information anyway because information is power, but there is no reason, technical or otherwise, except for greed, that ANI has to be provided to the recipient of the call. You may find that certain applications are worthwhile, and it should be your right to participate in those applications, but you should also have the right not to participate in those applications if you like. BTW, one way to get some privacy on 800 number calls is to call from a pay phone. > Now there really is very little the CRTC can do anyway, if the > 1-800 number is within the U.S., even assuming that this > capability is illegal, since the U.S. company is doing nothing > illegal under U.S. law, any more than the TV station in Canada > that broadcasts into the U.S. is not violating Canadian law even > though it is not licensed to broadcast on that station in the U.S. The CRTC could make it illegal to import or export ANI information. In fact, if the CRTC wants everyone in Canada to use a Canadian carrier, then blocking the export of ANI would help to achieve that restriction. Your analogy fails because it is technically impossible to have broadcasts stop at the boarder. It is technically possible to prohibit the export of ANI. David ------------------------------ Date: Wed, 1 Sep 93 02:25:01 EDT From: "Dennis G. Rears" Subject: Ramblings This started out as a "Moderator`s Note" to a article on ANI by David Gast . I then thought to myself I have a couple of minutes and thought I would ramble on. Hopefully the moderator will approve this article :-). I realized that I had a couple of paragraphs and decided to make it an article by itself. He had wrote: "Further, I do not buy the argument that just because someone pays for an 800 call, they deserve to be able to invade my privacy." How does somebody that you called on their nickel having your phone number "invade your privacy"? Anonymity, maybe? What exactly is privacy, anonymity? Let's See....... privacy n. 1. Seclusion or isolation from the view of, or contact with, others. 2. Secrecy, concealment. anonymity n. The quality or state of being unknown or obscure. 2. One that is anonymous. In this case, the knowledge of your phone number violates your anonymity, the use of it your privacy. If somebody calls you they have interrupted your activities. If you don't like it you can screen calls. The sheer fact that you have a telephone that can receive calls means that you have allowed anyone who dials that number to interrupt you. If you don't want somebody to know your phone number don't call them from that number. My phone number is 201.927.8757. I don't care who knows it. I care who calls it. Technology is here, it won't go away. If you use technology people can find out information about you. If have a radio receiver it can be determined what you are listening to. If you use credit cards they can determine your purchases. If you use atm cards they can determine where you've been. If you use celluear phones they can track your movements. Technology is a double edged sword. That is why I started this discussion group. I wanted a forum to discuss ways on how technology enhances privacy (encryption) and detracts from privacy (e.g. wide area databases). For the most part I gotten discussions about on the fringes of this. I gotten a lot of articles on SSNs. SSN are nothing but a key to a data base. If it wasn't for the SSN we have a another key (birthdate & address). The discussion should be about the use of the data base and who has access not if they have the right to ask it. I've been kind of disappointed about the types of discussion in this forum but unfortanetly (sp) I haven't really had the time to direct the discussions. I seen discussions if merchants have the right for driver license numbers, social security numbers, or phone numbers. They don't. If however you want want to cash that check they do. They want it to protect themselves if the check bounces not to get a database on you. Radio Shack just wants to send you a catalog. If you don't want it throw it out. In this digest we have one article about a spouse not wanting to reveal a SSN to his/her mate. Wow, whatever happened to the basic idea of marriage being a union? We can write until we are blue in the face about what should or should not be. However, privacy/anonymity is getting harder to safeguard. Let's start discussing ways to use existing technologies to our benefit. dennis ------------------------------ Date: Tue, 31 Aug 93 11:22:10 PDT From: Dave Gomberg Subject: Re: Computer Privacy Digest V3#019 Christy, I suggest that if you do not want your spouse to divulge your SSN, don't give it to her. And if you do not trust her, don't send her to the bank to do your banking business, go yourself. You wanted to save some time and energy, and then you are miffed when it works. What do you want?

(exceptions, etc.) ... So I suppose there is no law like the above that applies to non-governmental organizations. This is unfortunate. I have experienced what I would call housing discrimination resulting from my refusal to disclose my SSN. My basis for not divulging it was that I did not consider my relationship with the Social Security Administration to be directly relevant to my applying to rent an apartment. I'd like to see the situation change, but I can't imagine how that's going to happen.

Not all the information is on the slip -- the cards also have an expiration date recorded on their magnetic strip, and the thieves need to either glance at the card or improvise. An ex-employee of a bank in NY City who used to repair ATM machines was pulling off this scam a few years ago -- the bank found him because all his faked cards had the wrong expiration date (and the bank's software was still allowing the transactions even though the expiration dates were wrong).

How Does Line Blocking Work With Emergency Calls? If you have Line Blocking and an emergency service provider has Caller ID, the provider will NOT receive your number UNLESS you unblock your number by pressing *67 (dial 1167 on a rotary/pulse phone) before you call '911' or other seven digit emergency numbers. Line Blocking and Per-Call Blocking pertain to Caller ID only. Call Trace and Call Return are unaffected by either Line Blocking or Per-Call Blocking. --- # Monty Solomon / PO Box 2486 / Framingham, MA 01701-0405 # monty%roscom@think.com ------------------------------ End of Computer Privacy Digest V3 #020 ******************************
