In an exchange captured by Buzzfeed, Mark Zuckerberg’s sister and former marketing director Randi Zuckerberg posted a candid family photo on Facebook about “the family’s reaction to the site’s new ‘Poke’ app.”
Vox Media’s Callie Schweitzer saw the photo in her Facebook newsfeed and tweeted it. Zuckerberg objected.
It’s the never-ending story of Facebook. The New York Times technology blog, Bits, reports that Facebook has turned on facial recognition by default.
By default, this privacy setting tells Facebook servers to search its database for images you (and others) have tagged as you, and then compare that image to any new image a friend uploads. If the servers think they have a match, they will suggest your friend “tag” you in the photo. As the security company Sophos notes:
Remember, Facebook does not give you any right to pre-approve tags. Instead the onus is on you to untag yourself in any photo a friend has tagged you in. After the fact.
If you don’t want Facebook to suggest your name to friends when they upload photos of you, here’s how to change that setting.
Earlier this month, after reading Renay San Miguel’s article on Facebook application access to private information, I posted:
I’ve removed 80 percent of my FB applications and double-checked/changed permissions on the remaining few. Most of the [remaining] apps are there for my convenience: they allow me to post to FB from “outside” but none can access my data unless I’m using the application.
My announcement came in the wake of Facebook’s apparent effort to push members to share their postings by setting “everyone” as the default audience for four categories of information:
- about me;
- family and relationships;
- work and education; and
- posts (status updates, links, photos, videos and notes).

And you thought your biggest worry was online spyware.
Researchers at IBM have created a “smart” shopping cart which contains an interactive screen and scanner. If a shopper is part of a store’s loyalty system, the cart can provide a shopping list based upon her prior purchase. It can recommend items that are on sale. And it might contain a localized GPS system to show the route to a particular product in the store.
Reported by the Australian New Age, the cart is only one technology being tested, ostensibly to enhance the retail experience.
