[comp.society] Telephone Privacy

K4N@PSUVM.BITNET (Ken Nagelberg) (10/15/87)

[Article from CRTNET, October 14, 1987, Number 104]

     On NBC's TODAY show (10/7/87), a gentleman from New Jersey Bell
demonstrated a device which will be available to N.J. Bell subscribers.
The device instantaneously provides a readout of the telephone number of
anyone calling the subscriber's phone.  Thus, even if you have an un-
listed number or are calling an anonymous "hotline," your telephone
number would be in the hands of the person you called.

     This innovation raises a number of questions.  It breaks a number
of assumptions we have held about telephone use.  The benefits have, of
course, been touted by the phone company (which stands to profit by its
use).  A child picks up a phone in an emergency and dials 911 or 0, and
the operator instantly registers the orginating number.  Obscene phone
calls are instantly traced to their source.  On the other hand, so are
calls to the IRS, computer bulletin boards, and AIDS hotlines.

     Many are concerned with the "chilling" effect of such devices--will
the potential presence of such devices cut down on potentially beneficial
uses of the telephone as well as potentially criminal (or at least annoy--
ing) uses?  Perhaps the biggest effect will be an increase in pay telephone
use (again, more economic benefit to the phone company)!  Any reactions?

Let's not just assume that.  In what ways does it stand to profit?
By selling the devices?  Will they charge extra monthly for their
use?  It seems more like a "hey, look how good a phone company
we are and how we make technological innovations (just like we did
when we had Bell Labs :-)" kind of thing than a major profit-making
venture.  Phone companies have to compete with others for local
monopolies....  Anyway, to the real issues:

> A child picks up a phone in an emergency and dials 911 or 0, and

Almost all modern 911 systems already do this; from what I hear,
the 911 operator gets a screen with the calling number, name(s),
address, and any special medical information they may have on file.

> Obscene phone calls are instantly traced to their source.

But as you point out, these people can still use pay phones.
Once it is known that this kind of device exists, people will
find ways around it.

> On the other hand, so are calls to the IRS, computer bulletin

Exactly.  That's why a method is needed of making "anonymous" calls;
something the caller can do to cause their number not to be displayed.
Does anyone know if anything like this is proposed?  In any case,
I can't see an AIDS hotline, for example, wanting to install one of
these devices, and this would actually enhance computer security.
Systems with modem lines would install recording versions of these
devices on those lines, and if a break-in is attempted....  Many
legitimate bulletin boards these days are requesting phone numbers
and calling them back for verification before they allow access;
only those using boards that encourage illegal activities should
worry, but the owners of those boards would be very reluctant to
give that information out, and we want to hamper criminal activities
anyway, right....

I think it will just pose a new set of rules for interaction via telephone.
Society has adapted to plenty of changes in the phone system; it will adapt as
it adapted to party lines, direct dialing, call waiting, and other innovations.
Phone Phreaks will use their current techniques of "bouncing" calls off
of other numbers to hide their identity or figure out ways of sending
their own "calling number" tones to override the phone company's; people
will call BBSs through intermediaries like PC Pursuit more often, and
the general public will become aware of the difference between incoming
and outgoing PBX trunks :-).  This sounds like a good subject for a
good science fiction story (the kind that shows the subtle effects
of a new technology on people's lives)....

In general, it's important to look at this from the called party's perspective
as well.  The claim could be made that the person being called has a right to
know who is calling, and that this applies to individuals, business, and
government.  (Remember, the government is just another user of the system;
it's not taking advantage of any authority in using devices like these.
In most other countries, the phone system is part of the national government,
and is usually the same entity as the postal service; here we have the
situation that the phone companies are as interested in serving private
users and businesses as they are the government.)

Any thoughts on my ramblings?

When you dial 911 the operator not only gets your number, but also your 
address, displayed on a screen within seconds. This is according to the 
guy who was the instructor at our CPR and first aid classes.  At least, 
this is the way it is in parts of the Bay Area.

Apparently the system works well enough that in an extreme case, you can pass 
out while dialing 911, and as long as the call completes, an emergency 
response vehicle can be dispatched. Our instructor points out that response 
is often significantly faster if you can say what the problem is, though!

When I called out the police the other night to get the stereo thief
who was breaking into the car outside my house, I was very impressed
by the speed of the response. I think they were there in less than a minute
from when I started the call!  They seemed to have more information than
I told the operator over the phone; for example which side of the road
the house was on.

Just so we are not too naive about this: I am a member of the AT&T Bell Labs
software laboratory developing this feature for the 5ESS (tm) telephone
switch.  If C&P is using this feature on a 5ESS (tm) switch:

(1) AT&T will profit in selling this software to C&P.

(2) C&P will charge customers who wish to have this Calling ID feature
	a monthly fee per phone line, just as for Call Forwarding, Call 
	Waiting, or any other feature.

(3) C&P will also offer a "Calling ID Privacy" feature where, for an
	additional fee, a customer may specify that his/her number is
	NOT to be displayed if he/she calls a line with the Calling ID
	feature.

The "device" required to get the number displayed is an ISDN-compatible
"telephone/terminal" or CPE.  These devices will be sold freely by various
manufacturers just as telephones are sold today.

Interesting it is how many articles I've read that have implied or
declared that display of calling number is a violation of the caller's
right of privacy.  In my opinion, the telephone is the most intrusive
device ever invented.  If someday I can tell who is calling before I
pick up the phone, I will consider that innovation the biggest boon to
privacy since the device was invented.

Hello,

I thought I would put in my two cents worth on this subject.  As far
as I am concerned, it is entirely reasonable for me to know who is
calling me in advance - if someone is calling me, then presumably,
they want me to know who they are and what they want.  This system
would allow me to know when people I want to talk to are calling, and
when I should let the answering machine get the call for me (e.g. sales
calls).  

To date, the only people who have not wanted me to know who they are
are the obscene callers who have called me - I am not concerned about
their privacy.

One the calling side, I have never needed to conceal my identity from
the person I am calling - even when I have called the IRS.  I realize
that their are people who feel that they should not be identified to
such organizations; apparently, the identification feature can be
overridden at the calling side (I will, however, not answer such a
call). Apparently, if the identification feature is overridden when
calling 911, the call will not be put through - which is apparently
done to satisfy privacy requirements.  

A note - much of the this has also been discussed in the telcom
discussion, which has included a more extensive description of the
service provided.

So your're selling a service which will allow people to invade the
privacy of others, AND selling a service which people need to have to
block such an invasion.  I don't mean to flame YOU, Greg, but this is
really rotten.  I think you should tell your manager about this net
discussion, and that people are objecting to this system on ethical grounds.

I see no way anyone can make an anonymous phone call to someone who would
recognize their voice, thus the "privacy" of the caller is not changed. If
I am calling someone who does not know me, they will not recognize the number
anyway - thus, the "privacy" lost is meaningless information to the callee.

In addition, my privacy is invaded when someone else calls *me*, not when
I call someone  who will know the number I called from. As someone posted
earlier, I would be glad to be able to screen calls before I answer. This way
I could avoid such inconveniences as answering computer-originated advertising
calls, and other such verbal junk mail.

However, just to clarify (is this correct, Greg?):

	1. If I buy the Calling ID feature, I will know what number called me.
	2. If I buy the blocker, I will prevent others (with Calling ID) from
	      knowing where I called from (useless feature in my opinion).

For a caller without the blocker, the callee still does not know *who* called, 
just the number. If made from a number not yours, the callee still knows
nothing of value to him.

Suppose that I have an unlisted telephone number. I certainly don't
want some/most of the people I call to know what number I am calling
from as this is tantamount to giving out my number. Suppose that I am
calling some bussiness establishment which has one of those call id
things installed. It seems that blocking the call id needs to be made
an automatic no extra cost feature of the unlisted number option.

Reneerb@byuvax.bitnet (Allen Reneer) (11/14/87)

Could it be possible for people with unlisted numbers ( or who don't want
their number shown ) to have some other type of information shown?
     
Let's say people with unlisted number have their name shown on the display
instead of the number.  Then the person receiving the call will know where
the call is coming from but will not be able to get the unlisted number.
