Recently a controversy erupted over Facebook Phonebook, an app that shares users’ phone numbers without permission. Generally, Facebook can only share your number if you posted it and made it public via your privacy settings. However, by synching with your smartphone’s contacts, this app can share a phone number that has not been published. (This link will show you exactly how to hide your number on Facebook, though it won’t prevent your friends from possibly sharing your number with Phonebook.)
All of this talk has led me to wonder: should I put my phone number online?
I don’t know about you, but I am really paranoid when it comes to putting my details online. I don’t just worry about the ultra-sensitive information, like bank details and card numbers. I worry about my identity, my name, date of birth, my address and my phone number.
I’ve given the issue some thought to try to work out what it is that I am worried about and whether I am being a little too cautious. After all, I have found it useful to look up my friends’ phone numbers on social media sites when my phone has let me down, so why should I withhold the same information from them? I am quite security conscious, so I probably have less to worry about than the average internet user.
But what might the average internet user have to worry about?
By far the most common threat is that which gives a criminal direct access to your finances. Your bank details can be stolen in a number of ways. There is no point in making it even easier by broadcasting your account numbers, card numbers or passwords. Other information, like your address and number, might be useful if it comes paired with your bank details, but they are not usually needed for criminals to make a profit from your account.
By social sabotage I mean anything that could ruin your reputation with your peers. You can socially sabotage yourself by allowing your boss to see a photo of you hosting a late night party in the office. Your (one time) friend can publish the picture without your consent. Both of these problems are common and they are a reason to be careful about who you invite into your social circles and of what you say and do.
A lesser problem is that your account is hacked and your reputation is ruined by an action supposedly performed by you. This is not as common. It is most likely to happen if you have immature friends, rebellious children or a jilted ex-partner and can be prevented by having a completely secret and impossible-to-guess password.
This is where you would have to worry about putting your address and phone number online. It is not very likely to happen though. It is most likely to happen as part of a banking scam and for that, as already mentioned, your phone number and address tend to be of secondary importance compared to your card numbers and account details.
The other thing you should know is that if anyone wants to find your address and phone number online, the chances are that they already can. It doesn’t matter if you did not publish them anywhere yourself. Phone directories are online and have been for some time. I found three services in Finland alone that claimed to be able to give me the personal details of people I know if I logged in to their services. For the USA, there are sites like Spokeo.
These sites do not only give out your phone number and address, regardless of whether you know their existence, but they often collate other data. They will tell other people what you have posted in Yahoo! Groups (the titles of these posts are visible even if the group is private). They will gather your date of birth, gender, relationship status. Some may even gather photos of you. Your house. Your children. Whatever seems to be related to you online.
All this information is out there already. These sites just make it easier to find. Most of the time no-one is going to use those sites and there is no need to worry. If you are paranoid then you can search for yourself and hunt down all the places your information is being leaked from. Usually the only reason to be this paranoid about your data is if you know that someone is out to get you! By this I mean that you are involved in a legal matter or that your livelihood relies on your reputation.
There’s a very small chance that this problem will occur to you as an act of sabotage. You’ll suffer the loss of information from your online accounts, finding it deleted one day. This is most likely to happen because someone who is very close to you is angry with you. If this is happened to you, though, it is the second thing you should consider.
Before you rush to accuse someone of tampering with your accounts be aware that it is far more likely that an error with the software or website you use has caused your data to vanish. Always check with customer services first or search the internet to see if anyone else has the same problem at the same time.
Do you hold a crucial place in a business? Are you a government official? Are you a rebel to a strict governmental regime? Perhaps you’re a celebrity? Have a stalker? Messy divorce? No? Then you probably won’t ever have to worry about this.
If you ever intend to answer ‘yes’ to the above questions then it is a good idea to become more security savvy. Reading this blog is a good start, well done.
If you can answer ‘yes’ already, then you might be one of the few who are justified in being really paranoid and withholding most or all personal details from the online world. At the very least, seek advice relative to your position.
If you’ve skipped to the end looking for a summary, then the answer to whether you should put your phone number (or address) online is:
It is probably online already, but that does not mean that many people will know where to look for it.
Finally, if you want to respond to this article, please don’t call me! Leaving a comment on the blog will do nicely.

It’s going to be a busy month for sports lovers from all corners of the world. Hockey fans are currently being treated to both the NHL playoffs and the IIHF world cup, and the coming month will see things like the Champions League final, the US Masters, the NBA playoffs, and to top it all off, the European Championships in football. This presents a problem for many of us. Particularly during the summer, we travel a lot and just might be unable to find a TV screen showing our favorite events. So does this mean we have to miss Kevin Durant sink yet another 3-pointer or be content with next-day highlights of the CL final between Real and Atletico? Thankfully not! The internet allows us to stream games online and watch your favorite matches anywhere, whether at home or under a beach umbrella. Unfortunately, your excitement can often be hindered by messages like “Sorry, this content is unavailable in your country.” This is known as geo-blocking, where the services check your IP address (the unique address of your device) and only allow access if it is located in a specific country. The obvious solution then is to change your IP address to a country where you can access the service. And the easiest and quickest way to do this is with a VPN. How Freedome VPN works The way VPNs work is very simple. Instead of connecting to the internet directly, a VPN first directs your traffic into a secure and private tunnel. The rest of the web won’t see where your traffic enters the tunnel, making your real location and IP address hidden. A VPN like Freedome also lets you choose where the other end of that tunnel is, and THIS determines where any website will think you are. Pretending to be virtually in another country is that simple! How to use Freedome VPN to stream sports Follow these simple instructions to watch your favorite sports live everywhere! Download and install Freedome VPN In the Freedome app, tap the location at the bottom of the screen, and choose your home country where the stream you want to see is available Navigate to the website of the streaming service or search for a legal live stream of the sports event online If on a mobile device, remember to turn “location” off, as some websites use this as an additional method of pinpointing your location It’s as simple as that! More about Freedome VPN Freedome is a hybrid VPN, available for both mobile and desktop platforms. In addition to letting users access content restricted to other countries, it protects your anonymity from websites you visit, and prevents even your internet service provider from snooping on your online activities. There are even a few features lacking in other VPN products, such as automatic blocking of intrusive tracking by advertisers, and protection from malicious websites. Get Freedome from our website to enjoy unrestricted access to the internet while protecting your privacy on the side!
A recent PEW report says that 86 percent of people have taken action to avoid online surveillance, including simple things like clearing their browser cache, as well as using more effective methods, such as using a VPN (virtual private network). The same report says that 61 percent of participants indicated that they’d like to do more. Many people understand their privacy is at risk when they do things online, and want to do something about it. But that’s easier said than done. Not only do you have to have the will to make it happen, but you have to know where to start. Who do you want to protect your privacy from anyway? Facebook? The NSA? Nosey neighbors? PEW’s report says that 91 percent of people agree or strongly agree that consumers have lost control over personal information that is collected and used by companies. So if you want to take this control back, the first thing you need to do is figure out who’s stalking you online. F-Secure’s Freedome VPN, which you can try for free, has baked-in tracking protection technologies to help people protect their privacy while they’re surfing online. It also has Tracker Mapper – a feature that people can use to control how they expose themselves to Internet trackers. Tracker Mapper has been available for Macs and Windows PCs for about half a year, and was just launched for Freedome’s Android and iOS apps. So how does using Tracker Mapper help you control your online privacy? Here’s our Chief Research Officer, Mikko Hyppönen, talking about how online tracking threatens people’s privacy, and how Freedome (and Tracker Mapper) can help people protect themselves. [youtube=https://www.youtube.com/watch?v=X1F8sHjCBx0&w=560&h=315] I ran a little experiment to help me learn how to limit my exposure to trackers while planning a vacation. I used Alexa to help me find some popular travel websites that I could use to shop for deals on hotels. After that, I turned on Tracker Mapper (which is turned off by default, because we respect the fact that people don’t want apps to create logs without permission) so I could find out which of these websites used the most tracking to study me as I used their site. I chose 5 of the more popular sites, and then I spent about 10 minutes on each, and left a bit of extra time so I could check out the results in between. The whole thing took me about an hour, giving me a one-hour log of the tracking attempts Freedome blocked while I browsed these sites. Tracker Mapper creates an interactive visualization of the blocked tracking attempts, and gives you information on what trackers attempted to monitor you on different websites. It also shows how these trackers link together to create a network capable of monitoring you as you navigate from website to website. These are screenshots showing how Tracker Mapper visualizes online tracking, as well some of the statistics it provides. The capture on the left shows the entire overview of the session (which lasted exactly one hour). The shot in the middle shows the sites I visited ordered by the most tracking attempts. The capture on the right shows the actual trackers that attempted to track me during my session, ordered by the number of blocked attempts. Based on this, Trip Advisor appears to have made the most tracking attempts. But you can learn even more about this by combining Tracker Mapper with a bit of online digging. You can tap on the different “bubbles” in Tracker Mapper to pull up statistics about different websites and tracking services. The first screen capture shows how many tracking attempts from different services were blocked when I visited Trip Advisor. The next two show the most prominent tracking services Freedome blocked – the tracker that TripAdvisor has integrated into its website (www.tripadvisor.com), and a tracking tag from Scorecard Research (b.scorecardresearch.com). As you might have guessed, TripAdvisor’s own tracking service is only used on their website (it’s what’s called “first-party tracking”). That’s why Tracker Mapper doesn’t show any connections between it and other websites. The second one, Scorecard Research, is used on both Trip Advisor and Lonely Planet. That’s why there are lines connecting it with both (it’s what’s called “third-party tracking”). Scorecard research is a marketing research firm that provides tracking and analytic services by having websites host their “tags”, which collect information about those website’s visitors. The Guardian has an excellent write-up about Scorecard Research, but what’s missing from the Guardian story is that you can opt-out of Scorecard Research’s tracking. Basically, they put a cookie on your browser, which isn’t an uncommon way for tracking companies to allow web surfers to protect their privacy (and oddly enough, a common way for them to track you). Stripping trackers out of websites lets people take control of who’s monitoring what they do online. PEW’s survey found that this idea of control is central to people’s concerns about online privacy - 74 percent of respondents said it’s important to control who can get information, and 65 percent said its important to control what information is collected. However, opting out of every tracking service (and for every browser you use) by installing opt-out cookies isn’t as convenient as using Freedome. And as F-Secure Security Advisor Sean Sullivan pointed out in this blog post, it actually works much better for your browsing (one experiment found that Freedome can reduce the time it takes to load web pages by about 30 percent, and decrease data consumption by about 13 percent). You can download Freedome for a free trial and find out for yourself if how it can help you control your online privacy. And right now, you can win free annual subscriptions, as well as cool swag (like stylish hoodies) by posting a screenshot showing your blocked tracking attempts to F-Secure’s Facebook wall, or on Instagram with F-Secure tagged. The contest is open till March 23rd, and 5 winners will be randomly drawn after it ends.
When George Lucas' Star Wars Episode IV: A New Hope hit theaters in May 25, 1977 the vision of a world that existed a "long time ago, in a galaxy far, far away" was startlingly new. The film opens with a massive Imperial Star Destroyer chasing a rebel ship and features routine space travel and battles suggestive of both of the age of King Arthur and a high-tech future, as depicted by visual effects pioneers Industrial Light & Magic. It also features a wire-frame animation (replicated below) of the Death Star, one of the first uses of computer animation ever to make it into a motion picture. [youtube https://www.youtube.com/watch?v=lVMnwd4mZlA] Less than a month later, history was made in the personal computer industry when Apple released the Apple II on June 10, 1977. At $1,298 -- which is just over $5,000 in today's U.S. dollars -- the machine that operated using Applesoft BASIC would become one of the first microcomputers to win widespread adoption, eventually expanding personal computing beyond hobbyists by offering business applications like VisiCalc, the first computer spreadsheet program for PCs. By the time Apple phased out the II series in 1993 between 5 and 6 million units had been sold. During 1999, the year when Lucas launched his first of the prequels Star Wars Episode I: The Phantom Menace, more than 114 million PCs were sold and the explosion of the World Wide Web had sped up widespread adoption of internet-connected computers. EverQuest -- the second massively multi-player online game after Ultima Online and the first with a 3-D engine -- was released on March 16, 1999 and within months more than two-hundred thousand players had subscribed. On May 19th, Phantom Menace hit theaters with only one scene that wasn't altered by visual effects. It was the first Star Wars film to feature fully computer generated characters including Jar Jar Binks, so maybe that wasn't a great idea. That year Apple released its its iMac computers in a variety of colors, Intel released its Pentium III and the computer virus Melissa -- the first able to spread itself through email -- became the fastest spreading malware ever and hit 250,000 PCs worldwide. The Mobile Web also debuted in Japan via the i-mode networking standard. According to the Computer History Museum Timeline of Computer History, it offered "web access, e-mail, mobile payments, streaming video, and many other features that the rest of the world won't see for nearly another decade." Free PC gave away 10,000 Compaq computers, one of many companies that offered hardware or Internet access in exchange for viewing ads. Many of these companies were bankrupt by December of that year. This is what a 1999-era Compaq running Windows 98 looks like: [youtube https://www.youtube.com/watch?v=ii51iSCnE0Q] The full trailer of Star Wars Episode VII: The Force Awakens debuted in October of 2015. [youtube https://www.youtube.com/watch?v=sGbxmsDFVnE] This follows only six months after Apple introduced its Apple Watch wearable device. The number of computers sold each year -- when you combine personal computers with smartphones and tablets -- now numbers in the billions with more than a billion devices powered by Google's Android operating system alone being sold each year. The largest PC maker in the world Lenovo sold 58 million units in 2014. The director of The Force Awakens J.J. Abrams had no input whatsoever from its creator George Lucas who sold to the franchise to Disney. But Abrams studiously sought to connect the new film to the original trilogy. He did this both by working with the writer of Episode IV: The Empire Strikes Back Lawrence Kasdan and through effects that focused on continuity with the movie's predecessors, with only a judicious use of computer generated images.
