BUSlink CipherShield encrypted hard drive prevents unauthorized access to your digital data. Using the latest cryptography algorithm software to protect sensitive file is nothing new. However, loading that same encryption into a removable CipherKey - that when removed not only makes all the data stored completely unreadable, but the drive itself becomes transparent and is completely invisible to the operating system. Plug the CipherKey in, the drive is once again visible and files immediately decrypted and accessible. Now that's new. The fact that this drive can plug into any USB port and is immediately accessible on any operating system, is just icing on the cake.
