Computers include ports for user interfaces, such as graphical user interface ports for mice and ports for memory devices. The ports are designed to accept connectors operable according to standards such as Universal Serial Bus (USB) and FireWire2. Small portable memory devices, such as jump drives and memory sticks, are used to interface with computers to easily transfer data among computers.
The recent availability of portable memory devices has changed the way in which speakers at conferences and meetings present their slides. Speakers download their presentations from a memory device into a single laptop set up in the conference room to project the presentation. Each speaker then presents their respective talk while controlling the slides and, in some cases, the cursor from the laptop. As a replacement for a mouse, the laptops typically include touch pads and/or nubs to control the cursor. The touch pads and nubs are often awkward to maneuver for those people more familiar with the mouse-control of a cursor.
The portable memory devices are useful to lighten the load carried by the speaker, since her or she does not have to carry a laptop to make a presentation. However, the data on the portable memory devices is not secure. If the user of the portable memory device loses the device, a person who finds the portable memory device can download the data from the portable memory device to their computer. This is undesirable, since often the information on the portable memory device is confidential. Some portable memory devices are software protected but if the user wants to use the portable memory device on more than one personal computer, the password must also reside on the portable memory device. If the password is on the portable memory device, the device can be hacked for the password and is not completely secure.
Miniature mice are available to connect to laptops to replace the functionality of the finger pads or nubs. A speaker can bring a miniature mouse, such as, the IBM PS/2 Miniature Mouse Pointing Device or the IOGEAR Mini Mouse 800 model GME222, to the presentation. When the speaker is ready to present, he or she plugs the miniature mouse into the presentation laptop in order to control the cursor during a presentation. Alternatively, a speaker can use a wireless mouse, such as the Kensington 72117 Pocket Mouse. In either of these cases, the speaker must bring the mouse and the memory device to the presentation. Traveling with the mouse and the memory device can be awkward. The mice are fragile and can be damaged if carried in a pocket, a purse, or a briefcase. The memory device is small and can be difficult to locate in a briefcase or a purse.
It is desirable to find a simple system to provide a secure memory device that is easy to transport. It is further desirable to find a simple system to carry a mouse and a secure memory device, which also prevents damage to the mouse and/or the secure memory device.

The device includes a mouse having an encryption processor in communication with the processor unit, a memory and an encryption key. The memory has an unlock mode in which the memory is operable to communicate with the processor unit and has a lock mode in which the memory is not operable to communicate with the processor unit. The encryption processor locks the memory in the unlock mode when the encryption processor matches a received unlock code with the encryption key.
The invention provides in a second aspect a secure portable mouse memory system for use with a processor unit. The secure portable mouse memory system includes a mouse having a housing portion and an encryption processor located in the housing portion. The encryption processor is in communication with the processor unit and is operable to receive a locking code from a user of the processor unit. The secure portable mouse memory system also includes a memory located in the housing portion and an encryption key stored in the housing portion. The memory has a locking mode and the encryption processor sets the locking mode of the memory in an unlock mode when the encryption processor matches a received locking code with the encryption key.
The invention provides in a third aspect a portable mouse memory system including means for determining a match between an encryption key and a received locking code, means for setting a locking mode for a memory in a mouse having a memory, and means for transmitting data between the memory and a processor unit based on the setting of the locking mode.
The above and other features and advantages of the invention will become further apparent from the following detailed description of the presently preferred embodiments, read in conjunction with the accompanying drawings. The detailed description and drawings are merely illustrative of the invention, rather than limiting the scope of the invention being defined by the appended claims and equivalents thereof.
The present invention is illustrated by way of example and not limitation in the accompanying figures, in which like reference numbers indicate like elements, and in which:
In the following description, several well-known features of computer systems and mice operable as graphical user interfaces with computer systems are not shown or described so as not to obscure the present invention. Presented herein are several embodiments of a mouse with a secure memory in which a connection can be established between the mouse and a processor unit only if the owner of the mouse is identified by the mouse. The established connection is operable to transmit data between the mouse and the processor unit. When the connection is not established, the mouse, a mouse cord and a connector at the end of the mouse cord are operable to form a necklace. The necklace can be draped about the neck of a user to secure or attach the mouse to a user. The necklace is formed when the connector at one end of the mouse cord is inserted into a receptor port in a housing portion of the mouse.
A secure portable mouse memory system 5 includes the secure portable mouse memory device 10 in communication with the processor unit 70. The encryption processor 170 is in communication with the processor unit 70 and is operable to receive a locking code from a user of the processor unit 70. The locking code from the user is either an unlock code or a lock code. The memory 60 is operable to interface with the encryption processor 170. The memory 60 has a locking mode which is either a lock mode or an unlock mode. The encryption processor 170 sets the locking mode of the memory 60 in an unlock mode when the encryption processor 170 matches a received locking code with the encryption key 67. In this case, the received locking code is considered to be an unlock code.
If the encryption key 67 does not match the received locking code, the encryption processor 170 processor sets or maintains the locking mode of the memory 60 in a lock mode. In this case, the received locking code is considered to be a lock code.
Specifically in this configuration, when the processor connector end 50 is inserted into the processor receptor port 71, the encryption processor 170 prompts the user of the processor unit 70 via the mouse cord 35 for a locking code. The user enters the locking code, which is transmitted from the processor unit 70 to the memory 60 in the secure portable mouse memory device 10 via the mouse cord 35 and conductive trace lines (not shown) in the housing portion 21. The encryption processor 170 in the secure portable mouse memory device 10 receives the locking code from the user and compares the received locking code to the encryption key 67 in the memory 60. If the encryption processor 170 determines a match, the encryption processor 170 unlocks the memory 60 to put the memory in the unlock mode. In the unlock mode, the memory 60 is operable to communicate with the processor unit 70 via the mouse cord 35. If the encryption processor 170 does not determine a match between the encryption key 67 and the received locking code, the memory 60 remains in the locked mode. In the locked mode, data in the memory 60 is not communicated to the processor unit 70. The connection is additionally operable to transmit cursor control signals from the mouse 20 to the processor unit 70. The memory can be a Not-And (NAND) flash memory, a Not-Or (NOR) flash memory, Ferro-magnetic random access memory (FeRAM).
