Electronic security is essential, and aside from password protection and encryption, data deletion is a common way to remove information that shouldn’t forex trading workstations into other hands. There are tools out there for recovering deleted data at several levels. Some of them, such as forensic computer tools, are used by government and law enforcement agencies for investigation.
Others are used by hackers to gain access to sensitive information, resulting in damage and data theft. When you delete a file on your computer, it doesn’t leave your hard drive. Instead, it goes to the trash or recycle bin. But even if you empty the trash folder, those deleted files still reside in your computer.

It would seem that deleting text messages works about the same as deleting email, but that often isn’t the case.
