Face book announced that it will soon start automatically suggesting your name for tagging photos any time it thinks it recognizes you in a picture. This automatic facial recognition is the default and will be done unless you explicitly opt out.

It looks like you need to customize your privacy settings to disable this. In Facebook, look under the “account” menu and select “Privacy Settings”.

From there click the “Customize settings” link at the bottom of the table. Within there, look for ”Suggest photos of me to friends”, and set it to “Disabled”.

I suspect that few people will simply stumble on that.

Other people tagging you in photos can lead to embarrassment you might want to avoid. Having your name suggested just makes that more likely.

While you are at it, you might want to change the setting that allows others to “check you in” to locations. That can tell thieves you are away from home or stalkers where to find you.

CNN has a good article on the announcement. Facebook lets users opt out of facial recognition – CNN.com

Amid unrest, a hard new look at online anonymity | The Social – CNET News:

This article takes an interesting look at the issues with Facebook’s true name policy and the impact it has on activists and dissidents in repressive countries. It quite rightly talks about the fact that for most of the history of the Internet use of “screen names” was the default.

The odd thing about this debate is that there is basically no authentication of the names used. Many people assume that since most users are under true name that all of them are. It is trivial to set up a new account with a plausible name which can not be traced back to the real user.

I would hope that dissidents, activists and others at risk would take advantage of this simple capability to protect themselves. Yes, this is in violation of the terms of service, but I think it is for a much greater good.

If you choose to do this, take care with who you friend under this alias. If the social network you create matches your real one, or that of another account, it may be very easy to unmask your identity.

A reader of this blog recently emailed me to ask:

What s/w do you recommend to keep anonymous while using Gmail, IE, Outlook, and Facebook on a laptop?

This is actually a very tricky question because the nature of all of these tools, except Internet Explorer (IE), is to be associated with a visible and discoverable account and identity in the “cloud”. I will discuss IE last and separately.

Gmail ties to your gmail and other Google accounts. Outlook ties to some existing email account at some email provider. Facebook is tied to your Facebook account and is explicitly designed for making your information public.

The profound question here is, what do we even mean by being anonymous using these services? I would argue that the best one can manage is to be pseudonymous; that is to maintain a persistent and visible pseudonym / alias which, while discoverable, is not associated with your true identity.

Fortunately Gmail and Facebook are free and typically do not require any real credentials to set up an account, and many of the free email providers work similarly. Using Anonymizer Universal (AU), and a browser with no history or cache to set up the accounts would ensure they were not connected to your real identity. It is important that the accounts never be accessed in any way except through AU, or they will be forever after associated with your real IP address. Furthermore, it is critical that the browser used is never used for any activity connected to your real identity, or the cookies and other digital detritus in your browser may allow these sites (or other folks) to tie the pseudonym to your other real name accounts.

IE is in many ways the easiest because there is no underlying account, but all the same rules apply. You need to ensure that you isolate your anonymous or pseudonymous activity from your real name activity.

For all of this activity a virtual machine can be a very effective tool. For example, if you use a Mac you can use a virtual machine running Windows or Linux for all of your alias activities and use the normal operating system for your real name activities. Similar tools exist for other operating systems.

This WSJ article reports on a new privacy issue with Facebook. It turns out that their application infrastructure allow those applications access to your personal information independent of your privacy settings. They are then able to (and have in many cases been shown to) share that information with third parties. The specific information shared is your Facebook user ID, and in some cases your friend’s user IDs.

Many of the most popular applications have been shown to be sharing this information, including FarmVille, Texas HoldEm Poker and FrontierVille among others.

BBC News – Details of 100m Facebook users collected and published

Ron Bowes wrote some software which scanned through Facebook to capture any unprotected personal information from the website.

The collected data has been compiled in to a huge file which is available over BitTorrent among other free channels.

While the program did not access any protected information, it has exposed any and all users who have not taken the proper steps to restrict access to their Facebook accounts, either through error or lack of knowledge, awareness or prudence.

The fact that it has been captured and distributed also makes it impossible to ever effectively change or remove any of the collected information. It is out there in the wild and out of anyones hands or ability to corral or correct.
