Online Cheating Charges Upend Dartmouth Medical School; The New York Times, May 9, 2021

Natasha Singer and Online Cheating Charges Upend Dartmouth Medical School

The university accused 17 students of cheating on remote exams, raising questions about data mining and sowing mistrust on campus.

"At the heart of the accusations is Dartmouth’s use of the Canvas system to retroactively track student activity during remote exams without their knowledge. In the process, the medical school may have overstepped by using certain online activity data to try to pinpoint cheating, leading to some erroneous accusations, according to independent technology experts, a review of the software code and school documents obtained by The New York Times.

Dartmouth’s drive to root out cheating provides a sobering case study of how the coronavirus has accelerated colleges’ reliance on technology, normalizing student tracking in ways that are likely to endure after the pandemic.

While universities have long used anti-plagiarism software and other anti-cheating apps, the pandemic has pushed hundreds of schools that switched to remote learning to embrace more invasive tools. Over the last year, many have required students to download software that can take over their computers during remote exams or use webcams to monitor their eye movements for possibly suspicious activity, even as technology experts have warned that such tools can be invasive, insecure, unfair and inaccurate."

Ced Kurtz’s Techman Texts: Computer surveillance is a trade-off; Pittsburgh Post-Gazette, 4/7/15

Ced Kurtz, Pittsburgh Post-Gazette; Ced Kurtz’s Techman Texts: Computer surveillance is a trade-off:
"Bruce Schneier is a world-renowned cryptographer, computer security and privacy specialist, and author of numerous books on security. So when he speaks, TechMan tends to listen.
In his latest book, “Data and Goliath: The Hidden Battles to Collect Your Data and Control Your World,” his point is well worth taking note of: Surveillance and data collections are a trade-off between individual value and group value. You give Google personal information in return for free search, free email, free maps and all the other free things Google provides...
Although hackers tend to get the headlines for the personal data they steal, a far bigger issue is the personal data you give away freely every day in return for convenience.
Mr. Schneier points out that all those data are saved in massive databases that can be data-mined by businesses, government and law enforcement and sold to other agencies. And although the point is always made that data collected are not tied to your identity, Mr. Schneier shows that, with enough data about you, identifying you is not difficult."

Senator Seeks More Data Rights for Online Consumers; New York Times, 2/28/13

Natasha Singer, New York Times; Senator Seeks More Data Rights for Online Consumers: "Before his planned retirement from Congress at the end of next year, Senator John D. Rockefeller IV, the West Virginia Democrat, intends to give American consumers more meaningful control over personal data collected about them online. To that end, Mr. Rockefeller on Thursday introduced a bill called the “Do-Not-Track Online Act of 2013.” The bill would require the Federal Trade Commission to establish standardized mechanisms for people to use their Internet browsers to tell Web sites, advertising networks, data brokers and other online entities whether or not they were willing to submit to data-mining. The bill would also require the F.T.C. to develop rules to prohibit online services from amassing personal details about users who had opted out of such tracking."
