Blockchain mapping

Shannon Mattern for The Atlantic on how blockchain might be useful in mapping and as a replacement for GPS: Crypto-cartographers hope to use it for spatial verification—confirming that things are where they say they are, when they claim to be there. How might this be useful? Well, you could know precisely when an Amazon delivery drone drops a package on your doorstep, at which point the charge would post to...

When surveillance turns into stalking

Many surveillance apps cater to parents who want to keep tabs on their children who have mobile phones. Many of these apps are used for less parental purposes. Jennifer Valentino-DeVries for The New York Times reports: More than 200 apps and services offer would-be stalkers a variety of capabilities, from basic location tracking to harvesting texts and even secretly recording video, according to a new academic study. More than two...

Tracking her boyfriend on Strava

Elizabeth Barber was in a long-distance relationship, and Strava was a way for her to connect with him. It became a point of anxiety when her boyfriend cycled with someone else more and more often. I was curious, and Strava is a joyless data bank for the insecure. When The Washington Post reported in January that US military bases are visible in the GPS shadows of uniformed Stravites, I was...

Facebook logs calls and text messages

Woo. Woo. Alex Hern reporting for The Guardian: In at least one previous version of the Messenger app, Facebook only told users that the setting would enable them to “send and receive SMS in Messenger”, and presented the option to users without an obvious way to opt out: the prompt offered a big blue button reading “OK”, and a much smaller grey link to “settings”. Nowhere in the opt-in dialogue...

What Facebook and Google know about you

Facebook and Google (among other companies) know a lot about you through the services you use. Dylan Curran for The Guardian provides a rundown: This information has millions of nefarious uses. You say you’re not a terrorist. Then how come you were googling Isis? Work at Google and you’re suspicious of your wife? Perfect, just look up her location and search history for the last 10 years. Manage to gain...

The personal data you generate when you book a flight

Every time we book a flight, a Passenger Name Record is generated and saved by an outdated system, which links to private travel data. Paz Pena, Leil-Zahra Mortada and Rose Regina Lawrence for the Tactical Technology Collective outline that data and describe the consequences of the system failing to keep data private. But although the PNR system was originally designed to facilitate the sharing of information rather than the protection...

Secret army bases seen in public fitness tracking map

Last year, fitness tracking app Strava released a high detail map of public activity data. Looking more closely, security student Nathan Ruser noticed activity in various parts of the globe that revealed secret US army bases. Alex Hern for The Guardian reports: Zooming in on one of the larger bases clearly reveals its internal layout, as mapped out by the tracked jogging routes of numerous soldiers. The base itself is...

800 pages of Tinder data

Judith Duportail, writing for the Guardian, requested her personal data from dating service Tinder. She got back 800 pages of all the information she voluntarily gave away. As I flicked through page after page of my data I felt guilty. I was amazed by how much information I was voluntarily disclosing: from locations, interests and jobs, to pictures, music tastes and what I liked to eat. But I quickly realised...

Facebook still allowed race exclusion for housing advertisers

Last year, ProPublica revealed that Facebook allowed housing advertisers to exclude races in their campaigns. Facebook said they would address the issue. ProPublica returned to the topic. Facebook didn’t do a very good job. All of these groups are protected under the federal Fair Housing Act, which makes it illegal to publish any advertisement “with respect to the sale or rental of a dwelling that indicates any preference, limitation, or...
