Method for a personal DMZ-shared removable storage device with multiple USB connectors

Disclosed is a method for personal demilitarized zone (DMZ) shared removable storage device with multiple universal serial bus (USB) connectors. Benefits include improved functionality, improved security, improved ease of use, an improved development environment, and improved cost effectiveness.

Background

              Conventionally, all USB storage devices can connect to only one computer at a time.

              Pen drives or pen disks are portable USB flash memory products. They are detected by the operating system as removable storage. Repeatedly connecting a USB flash disk to one computer and storing data, then connecting to another computer and retrieving data can ruin the connectors of a pen drive after a few weeks of use.

              A requirement exists for a file-system-based DMZ. Demilitarized Zone is an idea of secure data exchange between insecure places.

              Most often DMZ is implemented as data storage that is accessible from at least two separate zones between which there is no possibility to transmit data directly (i.e. because of security or development works it is not possible to connect both devices via network). This separates both environments, because DMZs are implemented with use of network-shared devices that are accessed from separate networks. This arrangement requires good knowledge of networking and involves many infrastructure devices that are expensive and difficult to maintain. This solution does not resolve problems involved when network devices being developed are not able to communicate via the network, such as when the network interface is the object of development.

General description

              The disclosed method is a device that has more than one USB connector, enabling the device to connect to more than one computer at a time.

      The key elements of the method include:

•             Internal flash file system for storing data

•             Internal controller for access con...
