Abstract

A portable memory storage device is disclosed where access to information on the device is granted only upon proper biometric authentication of a user. The device includes a controller, a non-volatile memory which may be a flash memory, and a biometric scanner system for controlling access to the information within the non-volatile memory. Each of the controller, non-volatile memory and biometric scanner system may be mounted in a base of the portable device, with the biometric system having an exposed surface on a top portion of the base for accepting biometric data such as a fingerprint. A cover is provided which includes a USB connector capable of mating within a USB port of the host device to establish communications between the portable and host devices. The cover also covers the exposed portion of the biometric scanner to protect the sensor when the portable memory storage device is not in use.

Claims

1. A portable memory storage device operable with a host device, comprising:

a flexible cable having a first end and a second end;

a first section including a biometric device for receiving biometric data, the first section coupled to the first end of the flexible cable; and

a second section including a connector for establishing communication between the portable memory storage device and the host device, the second section coupled to the second end of the flexible cable, the flexible cable electrically coupling the first and second sections, the first section is separable and freely movable in three dimensional space with respect to the second section to an extent allowed by the flexible cable, and the second section capable of mating with, and at least partially covering, the first section.

2. A portable memory storage device as recited in claim 1, further comprising a semiconductor memory storage device in one of the first and second sections.

3. A portable memory storage device as recited in claim 1, further comprising a flash memory in one of the first and second sections.

4. A portable memory storage device as recited in claim 3, wherein access to information stored on the flash memory is allowed if biometric data received matches a stored reference pattern of biometric data.

5. A portable memory storage device as recited in claim 3, wherein access to information stored on the flash memory is prevented if biometric data received does not match a stored reference pattern of biometric data.

6. A portable memory storage device as recited in claim 3, further comprising a microcontroller in one of the first and second sections.

7. A portable memory storage device as recited in claim 3, the biometric device capable of communicating with the flash memory.

8. A portable memory storage device as recited in claim 1, wherein the flexible cable transfers communications between the first and second sections.

9. A portable memory storage device as recited in claim 1, wherein the biometric data includes one of a fingerprint, a thumbprint, voice data signal and retinal data image.

10. A portable memory storage device as recited in claim 1, the biometric scanner including a portion adjacent an upper surface of the first section, the second section covering the biometric scanner when mating with the first section.

11. A portable memory storage device as recited in claim 10, the first section including a docking enclosure, the connector fitting within an opening in the docking enclosure when the second section is mated with the first section.

12. A portable memory storage device as recited in claim 1, wherein the connector is capable of fitting within a USB port on the host device.

13. A portable memory storage device as recited in claim 1, wherein the first and second sections include structure for securing the first and second sections together when mated together.

14. A portable memory storage device as recited in claim 1, wherein the second section lies in full engagement with the first section when mated together.

15. A portable memory storage device as recited in claim 1, wherein the second section has portions spaced from the first portion when mated together.

16. A portable memory storage device as recited in claim 1, wherein the host device is one of a personal computer, a digital camera, a personal digital assistant and a cellular telephone.
