TECHNOLOGY, Facebook's Frictionless Sharing: A Privacy Guide

Should you be concerned about your privacy on Facebook's recently announced "frictionless sharing" plan that lets online sites and services automatically share your activity with your Facebook friends?
The basic idea behind Facebook's new sharing system is that clicking a "Like" button is too burdensome. So why not let a news site do the sharing for you, with almost no action on your part?
All you have to do is authorize a new Facebook application such as The Washington Post Social Reader, The Guardian's new Facebook app, or Yahoo news. Then every time you read a news article online, your activity will automatically be shared with your friends.
Think of it as silent sharing (at least, silent to you). Instead of clicking on a "Like" button, you need only click on an article link and your activity shows up in Facebook's new Ticker in the left hand column of your friends' Facebook home pages.
Shades of Beacon
The new functionality is reminiscent of Beacon, Facebook's now defunct over-sharing system that landed the social network in hot water in 2007. Under the Beacon plan, if you bought movie tickets from the Fandango site, say, Facebook would alert your Facebook friends.
The problem with Beacon was that it was an opt-out program, not opt-in. So Facebook users had to explicitly stop Beacon sites from leaking their online activity back to their friends instead of being given the choice about whether they wanted to participate in the first place.
Frictionless Authorizing
Frictionless sharing is different from Beacon, since you must explicitly authorize a site or app to share your information with Facebook. How this sharing mechanism works depends on the app. Authorizing The Washington Post or The Guardian Facebook apps allows you to read those news sites right within Facebook. The downside, however, is that everything you read is shared back to your friends.
Yahoo News works a little differently. The site has a function called "Social" that can be turned on or off. When it is turned on, frictionless sharing is in full effect, and everything you read is shared via the Facebook Ticker. Turn social off, and you're back to private mode, when only clicking on the Like button will send articles back to Facebook.
The Wall Street Journal also has a new Facebook app that allows you to read the Journal's articles within Facebook, but you must click the "Like" button to share content. Interestingly, however, whenever you open up the WSJ Social app, your friends are alerted that you are now reading The Wall Street Journal.
Facebook's new plans are not just for news services. You can use frictionless sharing to automatically share the music you're listening to through services such as Rdio and Spotify, share the movies and TV shows you watch via Hulu and Netflix, and reveal your fitness activity through Nike+.
Privacy Nightmare?
So, now everywhere you go, everything you do is being sent back to your Facebook friends and stored on company servers. Creepy, right? Maybe. But if you don't want your friends to know you love to read news stories about Lindsay Lohan or that you follow the details of every gruesome murder across the country, here's my advice: authorize wisely.
Don't use the new social functionality in Yahoo News or the Washington Post or Guardian apps if you're concerned about your reading habits leaking out. Instead, use the traditional "like" buttons to manually select what you want your friends to see.
If you do use automatic sharing apps, but want at least some control over who can see what you're up to, you can specify who on Facebook can see your activity. In my experience, most of these apps by default limit sharing to your friends, but you can also choose to share everything publicly or create a custom setting to only share with specific people.
Let's say you want to adjust your settings for Washington Post Social Reader. First, go to your App Settings page in Facebook and then click on the app's name. This will show you all the settings for the app, including the information it can access from your profile and the type of profile data it last accessed.
Toward the bottom, you will see a section called "App activity privacy," which will show you who can see your activity. Clicking on the button on the far left lets you choose to let everyone see your reading activity, restrict it to friends of friends, limit the information to your friends, or follow a custom setting defined by you. Once you select your preferred setting, hit the close button and you're done.
But this method is not foolproof, because your friends could turn around and share your activity with others. Let's say you read an article on Yahoo News and it pops up in the ticker of your friend Richard. He can then turn around and share that article with his friends, and so on.
So if you don't want people to see what you're reading or listening to, or how much you're running, the best thing to do is to keep it off Facebook.

TECHNOLOGY, Facebook's Timeline will Help Hackers

Facebook's new Timeline will make it even easier for criminals and others to mine the social network for personal information they can use to launch malicious attacks and steal passwords, a researcher said today.
Timeline, which Facebook unveiled yesterday at a developer conference and plans to roll out to users in a few weeks, summarizes important past events in a one-page display.
According to Facebook CEO Mark Zuckerberg, Timeline is "the story of your life."
That has experts at U.K.-based Sophos concerned.
"Timeline makes it a heck of a lot easier [for attackers] to collect information on people," said Chet Wisniewski, a Sophos security researcher. "It's not that the data isn't already there on Facebook, but it's currently not in an easy-to-use format."
Cybercriminals often unearth personal details from social networking sites to craft targeted attacks, noted Wisniewski, and Timeline will make their job simpler.
"And Facebook encourages people to fill in the blanks [in the Timeline]," said Wisniewski, referring to the new tool's prompting users to add details to sections that are blank.
Because people often use personal information to craft passwords or the security questions that some sites and services demand answered before passwords are changed, the more someone adds to Timeline, the more they put themselves at risk, said Wisniewski.
"Remember the hack of [former Alaska governor] Sarah Palin's account?" asked Wisniewski. "That hacker found the answers to her security questions online."
A former University of Tennessee student who bragged it took him just 45 minutes of research to reset Palin's Yahoo Mail account password was convicted on multiple federal felony counts last year.
Hackers can also use what they find on Facebook and elsewhere to craft convincing emails that include malware or links to malicious sites, noted Wisniewski, even if the individual is not the target.
"It may be about the fact that you work for RSA [Security]," he said, referring to the emails sent to low-level employees at that firm earlier this year. Those emails, which included malware embedded in Excel spreadsheets , gave attackers a foothold on RSA's network. The criminals then scoured RSA's systems and stole confidential information about its popular SecurID authentication token technology.
Others, not strictly hackers, could use Timeline to quickly dig up dirt as well, said Wisniewski.
"Someone could use it to gather information to harass you, or someone at work competing for your job could use it," he said.
"The more you put in there to make it complete -- and we've been conditioned to finish forms -- the easier it is for someone with ill intent to gather information about you," said Wisniewski.
Although current Facebook privacy settings will apply to the Timeline -- letting users decide who sees what -- and the Timeline can be edited to remove an embarrassing past, Wisniewski was pessimistic about users' decision making.
"Call us paranoid or prudent -- we're paid to worry about this -- but for 99% of people, the danger doesn't even cross their mind," said Wisniewski.
In an unscientific survey Sophos ran on its website today, nearly 50% agreed that the Facebook Timeline worried them, while about 17% said they liked the idea or would get used to it.
Wisniewski admitted that the poll probably doesn't reflect most Facebook users' opinions. "They're doubly self-selected," he acknowledged, "first for taking the survey and second because they're concerned enough about security to go to our website."

TECHNOLOGY, Facebook's New Timeline Layout: A Getting-Started Guide

Facebook CEO Mark Zuckerberg announcing TimelineFacebook's new profile layout, Timeline, promises to turn your Facebook account into an online scrapbook where you can highlight important moments in your life and resurface past Facebook activity.
"Timeline is the story of your life...in a new way to express who you are," Facebook CEO Mark Zuckerberg said on Thursday announcing the new feature.
As its name suggests, Timeline organizes your life in reverse chronological order based on the content you've shared on your Facebook profile. The layout is designed as a dual-column view with a large main column for viewing content and a smaller one on the right for fast navigation.
If you've entered when you graduated high school or college, when you got married, when your first child was born or when you started a new job, all that data will show up in your Timeline. You can also go back and add photos and captions to important past events if you want to, or remove particularly embarrassing photos or other content from your new profile page.
Timeline is currently in a limited beta for developers but, when I found out you could activate it immediately (thanks to a little developer program trickery explained below), I jumped right in to see what all the fuss was about.
While Timeline still has a few bugs to work out, it was a very interesting way to experience Facebook and a great way to look at your past activity. But, in my tests, there were also some privacy changes that may give some users pause.
Get Timeline Now
What a Timeline page looks likeTimeline won't officially launch for a few weeks, but if you want to try it right now, check out David Daw's how-to guide on activating Facebook Timeline right now. If you decide to take the plunge, keep in mind this is a developer beta so expect to see bugs. There are also no guarantees that an accident won't happen that briefly makes all your profile information public. So the risk is yours if you try Timeline.
You should also know that if you activate your Timeline now, only other people using the beta release will see your new Timeline, your non-beta friends will continue to see your old profile page. Although, Facebook will also specify a date when your Timeline will go live (mine was September 30). It's not clear if everyone will see my Timeline after that date.
If you do activate Timeline or you just want to see what you have to look forward to, here's a getting-started guide for Facebook's new profile layout.
Timeline Basics
When you first arrive on Timeline. you will be given the option to publish it right away or wait until you finish editing it before making the project go live. You will only have a limited time to keep your Timeline private, as Facebook sets a specific date for your Timeline to be published. In my tests, the social network gave you seven days, which should be plenty of time to get your profile in order.
At the top of Timeline sits a large photo--Facebook calls the cover photo--along with an inset of your profile photo. You get to select the cover photo. Below the right side of the cover photo, you will see three menu items: Update Info, View Activity, and a settings cog.
"Update Info" takes you to a new page where you can edit your basic profile information. including employment and education history, contact information, favorite quotes, places you've lived, and a list of your family members and relationships. The data you see populated on this page will depend on how much information you've included on your Facebook profile.
"View Activity" shows you a list view of all your Facebook activity that is organized by year since the date you joined Facebook. It includes such information as things you've written on friends' walls, photos and links you've shared, and photos you've been tagged in.
The settings cog includes a privacy setting that shows you what your Timeline will look like to specific Facebook friends or people on Facebook who are not your friends. The settings feature also allows you to add a Facebook badge to your own website. It's not clear today if the settings cog will change once Timeline goes public.

A little further down from your cover photo, you'll see your basic information listed, which includes where you live, where you studied, where you work, or other information that you may have included in your profile. You will also see a photo montage representing your Friends list, another photo showing the number of photos you've been tagged in, a map showing where you've lived, and a list of all the Facebook pages you've Liked.
There is also a down arrow that, when you click on it, will show you any new Open Graph Facebook apps you've added to your Timeline, such as the new The Wall Street Journal app. Here's an example:
