Definitions

• the privacy product causes an information system to display chaff paths so that - while a person controlling a cursor motion can recognize cursor motions - onlookers can not recognize cursor motions amidst chaff paths.
• the invention provides progress over prior art shown for example in U. S. patents 3,671 ,668 and 3,718,759 by Reiffel.
• FIG. 1 depicts the product schematically.
• FIG. 2 depicts the path of an input device controlling a cursor.
• FIG, 3 depicts a display of a segmented cursor path and chaff paths.
• the privacy product - depicted schematically in FIG. 1 - is used with an information system which has a data processor 71 signal connected 72 to a display device 81 and has an input device 51 signal connected 52 to the data processor.
• the input device is manipulated by a person to control cursor motions.
• the input device sends a motion signal to the data processor which the data processor uses to generate a cursor component of a display signal sent to the display device.
• the cursor component causes the display device to display a cursor path representing cursor motions.
• the privacy product comprises a computer readable signal bearing medium 11 signal connected 14 to the data processor.
• the medium has a chaff component 12 which causes the data processor to add a chaff component to the display signal.
• the chaff component causes the display device to display a chaff path which is indistinguishable from the cursor path by a sequent person.
• the clause "indistinguishable from the cursor path" means that there is no property of the chaff path, nor of the cursor path, distinguishable by anyone other than the person controlling cursor motions by which anyone other than the person controlling the cursor could tell which of the chaff path and the cursor path is trie cursor path.
• the information system can have a sequent input device 61 signal connected 62 to the data processor with the sequent input device being manipulated by a sequent person to control sequent cursor motions.
• the sequent input device sends a sequent motion signal to the data processor which the data processor uses to generate a sequent cursor component of the display signal sent to the display device.
• the sequent cursor component of the signal causes the display device to display a sequent cursor path representing sequent cursor motions.
• the chaff component of the medium also causes the data processor to add a sequent chaff component to the display signal which causes the display device to display a sequent chaff path which is indistinguishable from the cursor path by the person.
• the input device 51 is depicted in FIG. 2 as a computer mouse 51A signal connected 52A to the data processor and moving on a mouse pad 54A.
• the mouse has completed motions beginning by heading diagonally 21 toward a center, turning to head diagonally away 22 from the center, returning diagonally to and past 23 the center, returning diagonally toward the center, and turning to head diagonally away 24 from the center.
• a display device screen 82 display is depicted in FIG. 3.
• a first cursor path segment 31 representing a first cursor motion segment about 21 is displayed along with several chaff paths 31 A, 31 B, 31 C.
• a second cursor path segment 32 representing a second cursor motion segment about 22 is displayed along with several chaff paths 32A, 32B, 32C
• a third cursor path segment 33 representing a third cursor motion segment about 23 is displayed along with several chaff paths 33 A, 33B.
• the person controlling the input device can tell which among cursor path segments and chaff paths represents cursor motion segments because of the correspondence between manipulation of the input device and the cursor path segment.
• a sequent person - who is not controlling the cursor motion - can not distinguish the cursor path segments amidst the chaff paths.
• a sequent person controlling a sequent input device can tell which among sequent cursor path segments and all chaff paths represents sequent cursor motion segments because of the correspondence between manipulation of the sequent input device and the sequent path segment.
• the person - who is not controlling the sequent cursor motion - can not distinguish the sequent cursor path segments amidst all chaff paths.
• sequent cursor path segments and sequent chaff paths are not depicted.
• a display of a cursor path can be a display of the cursor only, can be a display of a line representing motions of the cursor, and can be combinations of these.
• a display of a chaff path can be a display of a chaff cursor only, can be a display of a line comprising the chaff path, and can be combinations of these.
• a displayed cursor is depicted 41 as about to enter a displayed location 86.
• Displayed chaff cursors - 41 A, 41 B, 41 C - are about to enter locations 85, 84, 83. Again while the person can tell that the displayed cursor is entering a location, the sequent person can not tell this amid the chaff.
• the medium can cause the displayed cursor and chaff cursors to blink at the same and different rates and can cause the displayed cursor and chaff cursors to change shapes according to a relationship and at random. A person controlling cursor motions can control cursor blinks and shape changes.
• Cursor blinks and shape changes are depicted in FIG. 3.
• the cursor 41 is a circle blinked on, a first chaff cursor 41 A has changed shape to a small circle and has blinked off, a second chaff cursor 41 B changed shape to a larger circle and blinked off, and a third chaff cursor 41 C has changed shape to a smaller circle and blinked on.
• Sounds can accompany the display of any, and all, of the displayed paths. Sounds accompanying display of a cursor path - including blinks and shape changes - can be controlled by the person controlling cursor motions. Sounds can be caused by the medium.
• Tactile signals corresponding to sounds accompanying a cursor path can be caused to be sent to the input device controlling cursor motions.
• the symmetry between the person, and the sequent person extends to symmetries between all pairs in a plurality of sequent persons. Each controls distinct motiohs via distinct input devices. Each can control distinct cursor blinks and cursor shape changes via distinct input devices. For each of the motions (and cursor blinks and shape change, if present), the chaff component can cause endless variations of chaff paths, cursor and chaff cursor blinks, cursor and chaff cursor shape changes, and combinations of these.
• the data processor can be a special purpose data processor, can be a general purpose data processor, can be stand-alone, can be part of a network, and can be stand-alone and part of a network in alternate time intervals.
• the computer-readable signal-bearing medium can be a transmitted signal, a data storage medium, and a combination of a transmitted signal and a data storage medium.
• the transmitted signal can be any of various point-to-point and broadcast forms of energy transmission - wireless and via wires, cables, and fibers - known in the art. Parts of the signal can reside with one form of the transmitted signal, parts can reside with a second form of transmitted signal, and parts can reside with various combinations of transmitted signals.
• the data storage medium can be any of various mechanical, electrical, magnetic, optical, molecular, atomic, and quantum data storage media known in the art. Parts of the computer-readable signal can reside with a data storage medium, parts can reside with a second data storage medium, parts can reside with the transmitted signal, parts can reside with a second transmitted signal, and parts can reside with various combinations data storage media and transmitted signals.
• an input device is depicted as a conventional computer mouse, any input device - including sound activated devices - which can be signal connected to a data processor can be used.
• the input devices disclosed in international patent application PCTUS0007538 and U. S. patent applications 60211471 and 60226183 can be used.
• the cursor display privacy product is especially useful for entering private information - such as a personal identification number - where onlookers could otherwise see the information.
• private information - such as a personal identification number - where onlookers could otherwise see the information.
