33 Bits of Entropy. Fingerprinting of RFID Tags and High-Tech Stalking. October 4, 2011 at 1:20 pm. Previous articles in this series looked at fingerprinting of blank paper. This article is about fingerprinting of RFID, a domain where research has directly investigated the privacy threat, namely tracking people in public. The principle behind RFID fingerprinting is the same as with digital cameras:. Why not just use them in the normal way? At the logical level, either because there is no authentication o...

De-anonymizing Social Networks | 33 Bits of Entropy
https://33bits.org/2009/03/19/de-anonymizing-social-networks
33 Bits of Entropy. March 19, 2009 at 11:09 am. Our social networks paper is finally officially out! It will be appearing at this year’s IEEE S&P (Oakland). Please read the FAQ about the paper. Operators of online social networks are increasingly sharing potentially sensitive information about users and their relationships with advertisers, application developers, and data-mining researchers. Privacy is typically protected by anonymization, i.e. Removing names, addresses, etc. Software, which in my opini...

Reidentification as Basic Science | 33 Bits of Entropy
https://33bits.org/2013/05/27/reidentification-as-basic-science
33 Bits of Entropy. Reidentification as Basic Science. May 27, 2013 at 6:16 am. This essay originally appeared. On the Bill of Health blog. As part of a conversation on the law, ethics and science of reidentification demonstrations. Do we publish these demonstrations to alert individuals to privacy risks? If our goal is to improve privacy, are we doing it in the best way possible? These algorithms are my primary object of study, and so I see reidentification research partly as basic science. First and fo...

Personalized coupons as a vehicle for perfect price discrimination | 33 Bits of Entropy

33 Bits of Entropy. Personalized coupons as a vehicle for perfect price discrimination. June 25, 2013 at 7:09 am. Given the pervasive tracking and profiling of our shopping and browsing habits, one would expect that retailers would be very good at individualized price discrimination figuring out what you or I would be willing to pay for an item using data mining, and tailoring prices accordingly. But this doesn’t seem to be happening. Why not? Which is why firms balk at overt price discrimination. 1 Coup...

33 Bits of Entropy. Price Discrimination is All Around You. June 2, 2011 at 2:48 pm. This is the first in a series of articles that will show how we’re at a turning point in the history of price discrimination and discuss the consequences. This article presents numerous examples of traditional price discrimination that you see today, many of which are funny, sad, or downright devious. What is willingness to pay, and how does the seller determine it? To illustrate, let me quote a hilarious story. She said...

Good and bad reasons for anonymizing data | 33 Bits of Entropy
https://33bits.org/2014/07/09/good-and-bad-reasons-for-anonymizing-data
33 Bits of Entropy. Good and bad reasons for anonymizing data. July 9, 2014 at 8:05 am. Ed Felten and I recently wrote a response. To a poorly reasoned defense of data anonymization. This doesn’t mean, however, that there’s never a place for anonymization. Here’s my personal view on some good and bad reasons for anonymizing data before sharing it. The auxiliary data needed for de-anonymization doesn’t currently exist publicly and/or on a large scale. We’re acting on the assumption that it won&#...The pri...

New Developments in Deanonymization | 33 Bits of Entropy
https://33bits.org/2012/12/17/new-developments-in-deanonymization
33 Bits of Entropy. New Developments in Deanonymization. December 17, 2012 at 8:59 am. This post is a roundup of developments in deanonymization in the last few months. Let’s start with two stories relating to how a malicious website can silently discover the identity of a visitor, which is an insidious type of privacy breach that I’ve written about quite a bit ( 1. Firefox bug exposed your identity. The first is a vulnerability resulting from a Firefox bug. In the implementation of functions like. Utili...

March 12, 2008. An interim Privacy Impact Assessment (PIA) has now been published by Phorm. You can read it here. Pdf] The PIA, produced by 80/20 Thinking Ltd, predicts the media and public backlash against Phorm, and leaves several questions unanswered, including "Can an external attacker gain access to the required information to re-link [an] individual [with their] unique identifier? Over the last few weeks, the story that BT, Virgin and TalkTalk are signed up to trial a new technology called Phorm.

Insecticidal Maniacs? | Tea Time at the Zoo
https://snailquake.wordpress.com/2013/06/02/insecticidal-maniacs
Confessions of an Animal Addict. Tea Time at the Zoo. I’m spending part of the summer dyeing dance flies at a nature reserve near Loch Lomond. Yesterday’s flies were electric blue. Today’s were day-glo orange. Tomorrow they will be lemon yellow. After dyeing them, I’m releasing them back into the wild. The high visibility will allow me to recognise them if I recapure any of them the following day. The jars of ethanol are for the malaise traps. As well as painting flies, we have set up traps on the re...
