Many readers of this digest will be interested in the article, “Information technology and dataveillance,” Roger A. Clarke, Communications of the ACM, 31(5): 498 - 512, May 1988. This is a long review with 78 references.
The author defines “dataveillance” to mean the systematic use of computing technology in the investigation or monitoring of the actions or communications of one or more persons. He distinguishes betwen “personal surveillance” - surveillance of an identified person, where there is a specific reason for the investigation, and “mass surveillance” - surveillance of large groups of people in order to identify individuals who might be of interest to investigators. The author concludes that computing technology is making it much easier to perform both kinds, a lot of it is going on and more can be expected.
The author says he does not argue that surveillance is intrinsically evil or that it should be ruled out altogether, but argues that much of what is in fact now going on is in general a bad thing, especially the mass surveillance. He concludes that privacy and civil liberties protections in place in most countries are inadequate to protect against these new surveillance techniques. The author says that he feels people working in computing, due to their special knowledge, have some special responsibility to consider privacy implications of their work, evaluate safeguards, and lobby for effective ones.

(Paraphrased from The Houston Post, 29 April)
A local newscast carried a story on a Herpes research project under way at Baylor College of Medicine, and displayed a phone number for volunteers to call — with appropriate assurances of confidentiality.
Not only was it the wrong number, it was the number for the "back door" to the public address system at Baylor (No indication of how large an area was covered — it is a big place.)
The callers, hearing a pick up but no answer “assumed it was an answering machine” and “gave their names, phone numbers, everything.”
I believe this points up an important “human factor.” People are a lot less cautious when they initiate a contact than when they are contacted. This explains the easy success of the typical “service spoof” attacks - password harvesters and “night deposit box out of order” scams. I don't have a magic answer for designers of services — it is very hard to design a service that is at all hard to spoof if the clients aren't at least a little bit cautious.
Second item:
One of the tigers went through a window in a door and killed an employee. It was at night and the public would not have been in immediate danger even in the daytime, but the incident nevertheless caused quite a ruckus.
The firm that designed the enclosure stated that the door design, including the window pane used, was “standard” for that kind of application. The tiger had no trouble going through it, and there was no indication that it was defective, nor that any other tiger would have had any trouble going through any other door of like design.
(Zoo officials have the big cats in holding cages while the window materials used in the (relatively new) cat facility are tested - by swinging miniature wrecking balls into them. The cat facility is a modern close-contact one - you can routinely find one of the lionesses sleeping against a window with the public on the other side - in a tunnel.)
Apparently quite a few nominally professional people in the world think that standards excuse them from thinking. Perhaps that explains the popularity of standards?
Applicability to computers? Gee, there aren't any people clamoring for standards in the computer industry, are there?

A society that depends upon any mechanism for its own proper functioning, cannot tolerate, much less encourage, any tampering with the intended operation of that mechanism.
Therefore, one is tempted to rise up in indignation at the idea of a qualified academic assigning a virus to his students. The next thing you know, they will be assigning plagiarism. How about the forgery of academic credentials? Perhaps we should offer a course in how to falsify research results. Or, perhaps, on how to trash another's experiments, notes or reports.
Perhaps it is a sign of immaturity that we are unable to recognize the moral equivalency. I will leave open the question of whether the immaturity is in the technology, the society, or academia.
I thought that we put this issue to bed several years ago when we stopped assigning the breaking of security. It seems that we did not.
For an academic to be unable to recognize that assignments, and the recognition that goes with their successful completion, encourages the behavior assigned, demonstrates a lack of understanding of the activity in which he is engaged. If he understands it, and still makes such an assignment, he demonstrates a lack of understanding of where his real interest rests.
Such irresponsible behavior may account, in part, for the anti-academic bias in our society and for the manifest distrust of the scientific establishment. It is of little wonder that the citizens of Cambridge, Massachusetts are reluctant to trust the likes of these with genetic engineering.
If there is any lesson that we should have learned from the computer, it is that understanding the effects of what we intend for it to do is a daunting task. Even getting it to do what we intend is not trivial. It seems to me, that there is plenty of material here for assignments; we need not look to assignments which are at best trivial, and at worst, dangerous.

Subscribers to this list may be interested in the recent article““Computer Viruses” by Peter J. Denning in the American Scientist, vol 76page 236. In particular, he discusses terminology. Paraphrasing his definitions:
Denning points out that these types often occur in combination. A Trojan Horse is the most common means of originally introducing a virus into a system. For example, a Trojan Horse compiler can attach a copy of the virus code to its output.
Defence against computer viruses comes out sounding like a message from the Surgeon General. Practice digital hygiene yourself. Don't exchange programs with anyone whose computer habits are not up to your own standards. Refuse to use software if the manufacturer's seal has been broken!
Maybe we need a "Centers for Computer Disease Control".

The real risk with the freon-halon-ozone controversy is best understood when you realize that the Third World countries were major opponents to the production freeze. The major uses of freons are:
Freons have been shown to be much cheaper and much safer than the alternative technologies. Only recently have there been indications that equally safe refrigeration technologies can be practical, and these will be many times more expensive.
In the Third World refrigeration means much more than a cool car. It can mean the difference between life and death. In food production, refrigeration allows produce to reach markets, to be stored safely. Without it (and most underdeveloped countries lack adequate refrigeration) food spoils, farm incomes drop dramatically, people go hungry, people starve. In medicine, refrigeration means medicines that don't spoil and blood transfusions. Lack of refrigeration means death. So the Third World countries opposed the removal of freons. Why agree to many thousands of deaths just to keep the Americans happy? The future environmental destruction is a good reason, but with so much at stake the evidence must be persuasive. Even with the new technologies, they must weigh the huge increase in costs against their limited incomes.
The evidence from the computer models is weaker than the press reports indicate. The measurements of world ozone show an increase of about 5% from 1960 to 1975 followed by a much larger and faster decrease of about 15% since then. The computer models do not predict or explain that increase. Their predictions of what altitudes would have how much of a decrease do not match the observed decreases. The models did not predict the Antarctic ‘hole', although this has a tentative explanation.
I believe that the real deciding factor was the intuitive decision by the negotiators that while the models were pretty inaccurate, the measurement data was accurate enough to make the trend very worrisome. The rapid action following confirmation of the satellite data calibration is consistent with this. It also is evidence of a cautious approach towards computer models. The research level was dramatically increased, both into the atmosphere and into freon substitutes, after the initial modeling results were published. Freon uses with easy substitutions (spray propellent) were eliminated in the US. Oddly, the Europeans did not follow suit. The drastic changes were studied, but no action taken until there was much more information.
The Montreal agreement also places real emphasis on more data gathering and analysis following the agreed freeze and reduction in production. The reduction goal can be met with changes in refrigeration and manufacturing without any change in fire protection uses. The United States may move internally for much larger reductions. The large chemical companies may decide to switch production entirely when suitable substitutes are found. Dow has announced its intention to completely phase out freon production. The international agreement is to reduce somewhat, then wait for more evidence from measurements.
