When you visit a website on your computer or mobile device, you are potentially sharing that information with advertisers, hackers, co-workers and governments. Even though the content you are viewing is likely to be encrypted with HTTPS, your metadata (including the URL and IP address of websites you visit, your IP address, the time and date, information about your web browser and computer hardware) can be collected and stored by anyone eavesdropping on the wire between you and the web server, to be used against you in targeted advertising campaigns, phishing scams, profiling, and soon robot assassination.
Is your Inbox full? Do you want to combine mail from multiple accounts into one convenient location? Are you concerned that your private messages are being stored insecurely (i.e. not encrypted) on a server that could be accessed by your co-workers, the government, or hackers?
This tutorial will show you how to download your email messages into a local mail reader (Thunderbird Portable) and backup the files securely (with encryption) in the cloud provider of your choice. I use Microsoft’s OneDrive in my example; you could use DropBox, Google Drive, OwnCloud, a network share, or local storage such as a USB drive.
In a previous post I showed how a firewall app on Android can prevent metadata leaks when you connect to a wireless network but have not yet connected to your VPN. This guide achieves the same goal with OpenVPN or Torguard Lite on a Linux PC, blocking all outgoing connections and then allowing connections only to the VPN server.
The Panopticon is a theoretical prison designed by English philosopher and social theorist Jeremy Bentham in the late 18th century. The shape of the prison places every inmate within view of a watchtower. Although it is physically impossible for the watchman to observe all cells at the same time, the fact that the inmates cannot know when they are being watched means that all inmates must act as though they are watched, effectively changing their behaviour.
If you connect to the internet through a public WiFi hotspot, or at school or at work, the metadata and contents of your online communications can be intercepted and viewed (or altered) by the network operator or another malicious party on the network. If you connect from an Australian residential address or personal mobile device, the Australian Government will be storing your metadata from 13 Oct 2015. One of the ways to protect your privacy is to send all of your internet traffic through a Virtual Private Network.
