  • Patent number: 9336402
    Abstract: Systems, methods, and devices that secure data on removable storage devices are presented. A token component can interface with a communication port on a host device. One or more removable storage devices can interface with one or more other communication ports on the host device. The token component includes a security component that, when interfaced with the host device, is employed to automatically and simultaneously enable access, encrypt data being stored in, and decrypt data being retrieved from the removable storage devices. When the token component is not interfaced with the host device, the removable storage devices are secured so that they cannot be accessed and data stored thereon cannot be retrieved and decrypted. A user optionally can utilize a password, which can be entered when the token component is interfaced with the host device, to facilitate controlling access to the removable storage devices and data encryption/decryption.
