Large eye through a magnifying glassWe may be fighting a losing battle with online privacy. As mentioned in last week’s blog on Internet Privacy, companies like Google, Facebook, and Amazon hoover up every crumb of information they can glean about us and use it to target us with ads and content that they think will appeal to us. As far as I know there’s isn’t any perfect strategy for maintaining online privacy, but there are lots of small things we can do that will certainly help.

I’m not concerned here with security on the internet as it relates to the safety of children, or trying to hide our identity so that we may be completely untraceable. I’m just trying to keep down the amount of un-necessary information we give to the likes of Google. These tips are equally valid in a home computer or business computer environment.

So, here are some tips. They’re not listed in any particular order. Some are easier to put into practice than others:

  • Create another email account that you never intend to use for “real” email. Don’t include your own real name in the account name and don’t give real data when completing the compulsory items of information in the account profile. Quote this email address on any websites that demand you supply one and where you don’t expect a normal, ongoing, email exchange (since you don’t want to have to keep checking this account for incoming emails). Having an “anonymous” account like this also helps in keeping spam out of your main email account.
  • If a website demands that you give personal information that is not connected with a financial transaction nor has other legal implications, then LIE. I will NOT give my real address or date of birth online when there is no legitimate NEED for it (and there are few legitimate needs except the protection of the other party in financial transactions). If I am entering a compulsory date of birth on a website where this is “relevant” (but not essential for financial reasons) then I enter a date that is close to my own (so that it makes no difference for the legitimate purposes of the website) but from which I can not be traced.
  • When filling in online forms, exercise judgement in completing any item that is not marked as compulsory (usually indicated by an asterisk or written in red). If they don’t require you to give a date of birth then why would you? If an item is compulsory but impertinent then LIE.
  • Don’t click on any “like” buttons in Facebook or anything similar (eg in Google).
  • Don’t take part in online quizzes or polls.
  • Preferably, don’t use Facebook at all. If you are a Facebook user and have any concerns at all about the privacy of your data, read this article about Facebook’s attitude to privacy.
  • Magnifying glass over computer keyboard

  • If you’re still keen to use Facebook, go through all the settings and mark everything private except what you explicitly wish to share.
  • If you use LinkedIn, do not click on ads without first changing your privacy settings to exclude monitoring your activity re ads.
  • Do not use Gmail or any of its branded versions (I think Virgin’s webmail is one of those). Google reads your emails and bombards you with “appropriate” Google ads (sponsored links). See last week’s blog on Internet Privacy.
  • If you must use Gmail, at least ensure that you sign out when you are not actually using the email as Google records everything you do in your browser if you are logged in as a Gmail user. They then use this info to target you with Google ads. I also sign out of other sites, such as Microsoft Live, as soon as I’ve finished with them.
  • Disable or remove browser add-ons that place “toolbars” and/or “search boxes” at the top of your browser. These often have tracking software in them. Incidentally, your browser performance will also be improved by doing this and your browser screen will be less cluttered.
  • Be very careful about “linking” any social networking site to any other (by giving any of them permission to access others). You might add data to one program, believing it to be private, forgetting that you have linked it to another program that sucks in what you thought was private data and spits it out somewhere more public.
  • Set your browser so that all cookies are deleted as soon as you close the browser (but this has implications – read on).
  • Set your browser to delete your browsing history as soon as you close your browser.
  • Set your browser to disallow third party cookies.
  • Turn off Amazon browsing history.
  • If you use Firefox or Chrome as your browser then you can install AdBlock Plus. This will stop most ads from appearing while you are browsing.
  • If you use Firefox, another excellent add-on is Better Privacy. This deletes the “flash cookies” that are placed on your hard drive by Flash Player. Flash cookies (also known as LSOs – Locally Stored Objects) are not removed or blocked along with other cookies.
  • Do not be misled into thinking that “private browsing” will give you any protection. It does suppress evidence on your own computer but it does not prevent sites you visit from recording your activity. Nevertheless, it may help to turn it on.
  • More technical ways of throwing websites off your scent include using proxy servers and using a dynamic IP address.
  • If you want to make an online purchase from a website that you don’t completely trust, you can use a prepaid Mastercard. This will limit your financial exposure to the value on the card and will also keep all your personal information from the website.

As if all this wasn’t already a nightmare worthy of a Kafka novel, some of these measures nullify others. You can turn off Amazon’s “browsing history” and, similarly, stop ask.com from retaining your history but the instructions to turn these off are held in cookies so if you delete cookies (as recommended above) you’re back to square one with these two sites. Doh!

Some of the tips above are easy to carry out and others less so. I haven’t attempted to give specific instructions (eg for different versions of different browsers) as it would just take too long.
