The Ultimate Guide To Online Privacy

If you’ve ever visited a website that handles even the smallest bit of your personal information, there’s a good chance (hopefully) that it’s asked you to read through a privacy policy or two. Rather than pour over the details, many of us simply click on ‘I AGREE!’ and proceed with using the application. Even the companies and websites involved understand this and make it as easy as possible to satisfy lawyers as well as users.

What’s the harm in essentially ignoring that privacy policy? While the majority of the time it’s harmless, there are some ne’er-do-wells that may gather your personal information and sell it to marketers, advertisers, or spammers. While terrible, it’s not unheard of.

According to a recent report, there’s a big reason users don’t read privacy policies: they’re too damn long. Of the top 1,000 websites, the longest privacy policy takes about 45 minutes to read…the average takes 10 minutes.

About 72% of these websites allow users to opt out of being tracked. However, about 40% make you make navigate to a different (sometimes hard-to-find) section of the website to opt out.

Happy Data Privacy Day!

Today (1/28/11) is the fourth annual Data Privacy Day. Dozens of countries have been celebrating with events throughout the week to inform and educate us all about our personal data rights and protections.

On this Data Privacy Day, there’s a huge push to create better ways for people to manage and protect their data. Google has tools like the Google Dashboard, the Ads Preferences Manager and encrypted search if you’re looking for some of the more popular ways to manage your Google interactions. Most recently, Google launched an extension for Chrome called Keep My Opt-Outs, which allows you to opt out permanently from ad tracking cookies. And pretty soon Chrome will be extending the availability of 2-step verification, an advanced account security solution that is now helping protect more than 1,000 new accounts a day from common problems like phishing and password compromise. Right now it’s available to Google Apps Accounts and should available to the general public in a few weeks.

How To See If You’re Being Tracked

From the Wall Street Journal (10/4/10): A new icon alerting users to behaviorally targeted advertising could soon start making its way onto more Web ads.

A group of online marketing associations started pushing the icon Monday as part of an effort to develop stricter self-regulation of the online data collection and advertising industry. The icon, a light blue triangle with an “i” in the middle, will indicate that the company is following self-regulatory principles. Along with the icon, a company can use phrases like “Why did I get this ad?” and “Ad Choices” to direct consumers to more information about behavioral data collection and privacy.

The companies involved in this new industry “need to talk to their audiences. They need to describe what they do, how they do it and the value it brings,” Randall Rothenberg, president of the Interactive Advertising Bureau, said in a statement.

The move toward self-regulation is aimed at warding off federal rules as the $23 billion-a-year online-ad industry increasingly makes use of behavioral tracking to target ads. The Wall Street Journal’s What They Know series has documented the growing use of cutting-edge Internet-tracking technology that allows for more relevant ads but also has raised concerns over privacy.

Congress and regulators are looking more closely at online tracking. Two bills have been introduced in the House of Representatives that would restrict the practice. The Federal Trade Commission is expected to issue new privacy guidelines by the end of the year and is considering a do-not-track registry that would allow consumers to opt out of behavioral targeting.

The coalition behind the icon released voluntary guidelines more than a year ago that called for websites and advertisers to clearly explain how they track consumers’ information and allow users to opt out of behavioral advertising. The icon is an extension of that effort.

Helpful Online Resources

Pidder is a German startup and, more importantly, the first social network based on privacy by design. Pia Pauls, a co-founder of the site, reached out to Edudemic to make everyone aware of Pidder and it’s definitely worth checking out. Here’s a synopsis directly from Pia:

In addition to social networking where you stay in control of your own data and only share it with those you deliberately choose, pidder is a place to easily and securely manage passwords and logins. Pidder even provides an identity management service allowing the use of pseudonyms.

In the long run, we envision Pidder as a building block within a global infrastructure that will provide user-centric identity management. Every user will be able to gracefully manage in every given situation what information they wish to reveal about themselves adequate for the respective interaction. Check out Pidder here for yourself!

Do not reveal personal information inadvertently.

You may be “shedding” personal details, including e-mail addresses and other contact information, without even knowing it unless you properly configure your Web browser. In your browser’s “Setup”, “Options” or “Preferences” menus, you may wish to use a pseudonym instead of your real name, and not enter an e-mail address, nor provide other personally identifiable information that you don’t wish to share. When visiting a site you trust you can choose to give them your info, in forms on their site; there is no need for your browser to potentially make this information available to all comers. Also be on the lookout for system-wide “Internet defaults” programs on your computer (some examples include Window’s Internet Control Panel, and MacOS’s Configuration Manager, and the third-party Mac utility named Internet Config). While they are useful for various things, like keeping multiple Web browers and other Internet tools consistent in how the treat downloaded files and such, they should probably also be anonymized just like your browser itself, if they contain any fields for personal information. Households with children may have an additional “security problem” – have you set clear rules for your kids, so that they know not to reveal personal information unless you OK it on a site-by-site basis? To view more ways to stay safe, visit

Be conscious of Web security.

Never submit a credit card number or other highly sensitive personal information without first making sure your connection is secure (encrypted). In Netscape, look for an closed lock (Windows) or unbroken key (Mac) icon at the bottom of the browser window. In Internet Explorer, look for a closed lock icon at the bottom (Windows) or near the top (Mac) of the browser window. In any browser, look at the URL (Web address) line – a secure connection will begin “https://” intead of “http://”. If you are at page that asks for such information but shows “http://” try adding the “s” yourself and hitting enter to reload the page (for Netscape or IE; in another browser, use whatever method is required by your browser to reload the page at the new URL). If you get an error message that the page or site does not exist, this probably means that the company is so clueless – and careless with your information and your money – that they don’t even have Web security. Take your business elsewhere.

Your browser itself gives away information about you, if your IP address can be tied to your identity (this is most commonly true of DSL and broadband users, rather than modem users, who are a dwindling minority).

Also be on the lookout for “spyware” – software that may be included with applications you install (games, utilities, whatever), the purpose of which is to silently spy on your online habits and other details and report it back to the company whose product you are using. One MS Windows solution for disabling spyware is the Ad-aware program (shareware, from ), which can remove spyware from your computer; it is based on a large collaboratively maintained database of information about spyware. Linux and Mac products of this sort are likely to appear soon.

Java, Javascript and ActiveX can also be used for spyware purposes. Support for these scripting languages can be disabled in your browser’s configuration options (a.k.a. preferences, settings, or properties). It is safest to surf with them turned off, and only turn them on when a site you trust and want to use requires them. If you don’t know if your browser supports these languages or don’t know if they are turned on you can use BrowserSpy to find out (along with a lot of other information about your Web browsing software):

Another form of spyware consists of “webbugs”, which typically manifest themselves as invisible or nearly invisible image files tied to cookies and javascripts that track your Web usage. See this webbug FAQ, for more details. Dealing with webbugs when they are embedded in an otherwise legitimate page is thorny, as there isn’t a surefire way to distinguish between webbugs and run-of-the-mill image files. But see the Privacy Foundation’s Bugnosis webbug detector ( – Windows MSIE only). When webbugs are loaded into popup pages, the solution is to close the popups (usually a small page with an ad, though some of them are “micropages” that you can barely see. A few may even use javascript tricks to keep you from closing them. If this happens, close all other browser windows, then you should be able to close the bug window). Another tip for defeating webbugs is to reject any cookies from Doubleclick, AdCast, LinkExchange and other “ad exchange networks” (cookie sharing rings), and any other cookies that are not from the site you are currently visiting (most third-party cookies are basically webbugs). Lastly on this topic, be aware that HTML-capable e-mail programs and Usenet newsreaders make webbugs work in your e-mail and newsgroups. If your mailer or newsreader has an option to turn off cookie support, you should certainly do so. There is hardly any imaginable legitimate use for a cookie in an email or a newsgroup posting.

Remember that YOU decide what information about yourself to reveal, when, why, and to whom.

Don’t give out personally-identifiable information too easily. Just as you might think twice about giving some clerk at the mall your home address and phone number, keep in mind that simply because a site asks for or demands personal information from you does not mean you have to give it. You do have to give accurate billing information if you are buying something, of course, but if you are registering with a free site that is a little too nosy for you, there is no law (in most places) against providing them with pseudonymous information. (However, it would probably be polite to use obviously fake addresses, such as “123 No Such Street, Nowhere, DC 01010″. If they are generating mailings based on this information – presumably in accordance with the terms of their privacy policy – they can probably weed such addresses out and not waste the postage on them. Definitely do NOT use someone else’s real address!) However, if you are required to agree to terms of service before using the free service, be sure those terms do not include a requirement that you provide correct information, unless the penalty is simply not being allowed to use the service any more, and you’re willing to pay that price if they figure out you are not providing them with your actual personally-identifiable information.

      I’m really sorry for being a bit harsh here, perhaps I should have worded myself differently, but I have taken a keen interest in privacy software for many years and this just strikes me as a very sad way to mislead people into buying stuff they can get better for free, or waste time trying stuff that will either not work at all or take lots of effort to make work. I’m sure it wasn’t intentional, but the article could have been much better researched. By trying some of thse wares for example, and perhaps recommending only 5-6 for each platform. For instance the free ones I listed above, which are free for starters and much better than most of this. Why pay for “Evidence Eliminator” when CCleaner does the same job for free and better for instance? Also why waste time trying to make arcane software work? And what about some insight….?

    Most of this software is crap or outdated software that does not work on modern computers. Perhaps 3% of it is useful.
