Online privacy used to be a given. Now it's fast becoming a luxury and even a commodity. So is it worth paying for your online anonymity? And how can you keep control over your digital data? Here are a few of the best options to consider. Ekko charges $5 a month or $50 a year. It's a secure web and app platform that provides user friendly security controls. You can password protect messages, redact them or set them to self destruct. It also lets you search anonymously across search engines. If you want truly private Internet searches, Private.me is a good option. Your search data is encrypted but you can personally revisit it or delete it entirely. Blur is an app that allows you to browse the Internet without being tracked or forced to provide personal information. It can also manage your passwords and block data collection companies. Ghostery is another popular option, with almost 30 million users. There's an option to see all the companies on a site that are tracking your data and block them. It also shows you the cookies, tags and web bugs that are being monitored. The average Web user is being tracked by around 100 advertising technologies each day, so it may well be time to take back control of your data.
