If you have a need to keep your information confidential in your computer you can contact Urban Net to encrypt your data (for Windows and Linux). This is useful if you share your computer with your family members, use a shared computer at work, you go to a Internet café, you have highly confidential staff (a journalist, a person in a governmental agency), if you have fear of being hack (you can hide banking information).
Your documents and other data after installing data encryption software will need a password for anyone to access. It will look like a partition or an hard drive that come up when you open the encrypted information. Once you close the encrypted information the drive will disappear (it will be hidden in an encrypted file that needs software and password to open). Your documents will be safe from any one else that may have access to your services.
