Description

光标显示保密产品The cursor shows confidential products

背景background

本申请受益于指定美国的国际申请PCTUS0021518并于2000年5月3日提出。This application has the benefit of International Application PCTUS0021518, filed May 3, 2000, designating the United States.

保密产品使得一个信息系统显示箔条路径(chaff path)以至于-当控制光标移动的一个人能确认光标移动时-旁观者不能在箔条路径中确认光标移动。The security product enables an information system to display the chaff path so that - while a person controlling the cursor movement can confirm the cursor movement - bystanders cannot confirm the cursor movement in the chaff path.

本发明提供作为现有技术例子显示的美国专利3,671,668和3,718,759(由Reiffel提出)中改进。附图The present invention provides improvements over US Patents 3,671,668 and 3,718,759 (by Reiffel) shown as examples of the prior art. Attached picture

图1描绘了示意的产品。Figure 1 depicts the schematic product.

图2描绘了控制一个光标的输入设备的路径。Figure 2 depicts the path of an input device controlling a cursor.

图3描绘了一个分段的光标路径和箔条路径的显示。描述Figure 3 depicts a segmented cursor path and chaff path display. describe

图1示意显示的保密产品被用于具有一个数据处理器71的一个信息系统，该处理器71信号连接72到一个显示设备81，以及具有信号连接52到数据处理器的输入设备51。通过一个人操纵输入设备以控制光标移动。The security product shown schematically in Figure 1 is used in an information system having a data processor 71 signally connected 72 to a display device 81, and an input device 51 having a signal connection 52 to the data processor. The input device is manipulated by a person to control cursor movement.

这里和整篇文章中的“信号连接”意味着信号在信号连接的设备之间的传递。"Signal connection" here and throughout this article means the transfer of signals between signal connected devices.

输入设备发送一个移动信号到数据处理器，该数据处理器用于产生发送到显示设备的一个显示信号的光标分量。该光标分量使显示设备显示表示光标移动的一个光标路径。The input device sends a movement signal to the data processor for generating 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 movement.

保密产品包括一个计算机可读信号承载介质11，其信号连接14到数据处理器。该介质具有箔条分量12，它使数据处理器增加一个箔条分量到显示信号中。箔条分量使显示设备显示一个箔条路径，它使得随后的一个人不能够识别光标路径。The secure product includes a computer readable signal bearing medium 11 having a signal connection 14 to a 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 makes the cursor path unrecognizable to a subsequent person.

句子“不能识别光标路径”意味着除了控制光标移动的人之外任何人不能识别箔条路径的特性，也不能识别光标路径的特性，除了控制光标的人能告诉箔条路径和光标路径的哪个是光标路径外任何人都不能。The sentence "does not recognize the cursor path" means that anyone other than the person controlling the movement of the cursor cannot recognize the properties of the chaff path, nor the characteristics of the cursor path, except that the person controlling the cursor can tell which of the chaff path and the cursor path No one outside the path of the cursor can.

信息系统可以具有一个相继的(sequent)输入设备61，其信号连接62到数据处理器，被一个随后的人所操纵该相继的输入设备以控制随后的光标移动。相继的输入设备发送一个继续的移动信号到数据处理器，该数据处理器用于产生发送到显示设备的显示信号的继续的光标分量。信号的继续的光标分量使显示设备显示表现继续的光标移动的一个相继的光标路径。The information system may have a sequential input device 61 with a signal connection 62 to the data processor, which is manipulated by a subsequent person to control subsequent cursor movements. Successive input devices send a continuing movement signal to the data processor for generating continuing cursor components of display signals sent to the display device. The continuing cursor component of the signal causes the display device to display a successive cursor path representing continued cursor movement.

这里，介质的箔条分量也使数据处理器增加一个相继的箔条分量到显示信号中，使得显示设备显示一个相继的箔条路径，该路径是不可由人从光标路径中识别。Here, the chaff component of the medium also causes the data processor to add a successive chaff component to the display signal, causing the display device to display a successive chaff path that is not discernible by a human from the cursor path.

此外，还可以具有介质的一个分段分量13，它使数据处理器分段显示信号的光标分量以至于光标分量使得显示设备显示光标路径段和相继的光标路径段，当一个相继的输入设备正在操作时。In addition, there may be a segmented component 13 of the medium which causes the data processor to segment the cursor component of the display signal such that the cursor component causes the display device to display the cursor path segment and subsequent cursor path segments when a subsequent input device is during operation.

图2中的输入设备51被描绘成一个计算机鼠标51A，其信号连接52A到数据处理器，并在一个鼠标垫54A上移动。这里，鼠标已经完全的移动，经对角的头位21开始朝着一个中心，转到远离中心的对角的头位22，再对角的返回到和经过23中心，朝着中心对角的返回，和转到对角的远离中心的头位24。The input device 51 in FIG. 2 is depicted as a computer mouse 51A with a signal connection 52A to the data processor and moved on a mouse pad 54A. Here, the mouse has moved completely, starting towards a center via the diagonal head position 21, turning to the diagonal head position 22 away from the center, and then returning diagonally to and passing the 23 center, towards the center diagonal Return, and go to the diagonal off-center head position 24.

图3示出了一个显示设备屏幕82。在该屏幕上，表示有关21的第一光标移动段的第一光标路径段31连同几个箔条路径31A，31B，31C一起被显示。此外，表示有关22的第二光标移动段的第二光标路径段32连同几个箔条路径32A，32B，32C一起被显示，并且表示有关23的第三光标移动段的第三光标路径段33连同几个箔条路径33A，33B一起被显示。FIG. 3 shows a display device screen 82 . On this screen, a first cursor path segment 31 representing a first cursor movement segment about 21 is displayed together with several chaff paths 31A, 31B, 31C. Furthermore, a second cursor path segment 32 representing a second cursor movement segment relating to 22 is displayed along with several chaff paths 32A, 32B, 32C, and a third cursor path segment 33 representing a third cursor movement segment relating to 23 It is shown along with several chaff paths 33A, 33B.

控制输入设备的人能告诉光标路径段和箔条路径中的哪个表示光标移动段，因为输入设备的操纵和光标路径段之间的对应。一个相继的人-他没进行控制光标移动-不能区分箔条路径中的光标路径段。The person controlling the input device can tell which of the cursor path segment and the chaff path represents the cursor movement segment because of the correspondence between the manipulation of the input device and the cursor path segment. A sequential person - who does not control cursor movement - cannot distinguish between cursor path segments in the chaff path.

对称地，控制一个相继的输入设备的一个相继的人能告诉在相继的光标路径段和所有的箔条路径中哪个代表相继的光标移动，因为在相继的输入设备操作和相继的路径段之间的对应。该人-没有对相继的光标移动进行的-不能在所有箔条路径中区分相继的光标路径段。Symmetrically, a successive person controlling a successive input device can tell which of the successive cursor path segments and all the chaff paths represents the successive cursor movement, because between successive input device manipulations and successive path segments corresponding to. The person - who has not performed on successive cursor movements - cannot distinguish successive cursor path segments among all chaff paths.

因为相对于“人”和“相继的人”的交换来说状况是对称的，因此，不描述相继的光标路径段和相继的箔条路径。尽管所述的路径由介质的分段分量被分段，该分段分量能被去掉以至于光标路径不会被分段。对此不进行描述，因为未分段的光标路径是怎样的我们很清楚。在没有分段分量的情况下，如果所描绘的是一种混乱物，则箔条路径能生成一个混乱物。Since the situation is symmetrical with respect to the exchange of "person" and "sequential person", successive cursor path segments and successive chaff paths are not described. Although the path described is segmented by the segment component of the medium, this segment component can be removed so that the cursor path is not segmented. This is not described, since we know exactly what the unsegmented cursor path looks like. In the absence of a segmented component, a chaff path can generate a clutter if one is depicted.

一个光标路径的显示可以仅是光标的显示，可以是表现光标移动的线路的显示，并可以是这些显示的组合形式。一个箔条路径的显示可以只是箔条光标的显示，可以是包括箔条路径的线路的显示，并可以是这些的组合。The display of a cursor path may be a display of only the cursor, a display of a line representing the movement of the cursor, or a combination of these displays. The display of a chaff path may be only the display of the chaff cursor, may be the display of the line including the chaff path, and may be a combination of these.

在图3中，显示的光标被描绘41为将要输入显示的位置86。显示的箔条光标-41A，41B，41C-是将要输入的位置85，84，83。再有，尽管该人能告诉显示的光标是正输入一个位置，但相继的人不能在箔条中告诉这些。In FIG. 3, a displayed cursor is depicted 41 as a location 86 where the display is to be entered. The displayed chaff cursors - 41A, 41B, 41C - are the positions 85, 84, 83 to be entered. Again, although the person can tell that the displayed cursor is entering a position, the subsequent person cannot tell this in the chaff.

介质能使显示的光标和箔条光标以相同的和不同的速率闪烁，并能使显示的光标和箔条光标按照一种关系和随机的改变形状。控制光标移动的一个人能控制光标闪烁和形状改变。The medium can cause the displayed cursor and the chaff cursor to blink at the same and different rates, and can cause the displayed cursor and the chaff cursor to change shape in a relationship and randomly. One who controls cursor movement can control cursor blinking and shape changing.

在图3中描绘了光标闪烁和形状改变。光标41是一个闪烁的圆，第一箔条光标41A已经改变形状到一个小圆并关闭闪烁，第二箔条光标41B改变形状到一个大圆并关闭闪烁，以及第三箔条光标41C已经改变形状到一个较小的圆和开启闪烁。Cursor blinking and shape changing are depicted in FIG. 3 . The cursor 41 is a blinking circle, the first chaff cursor 41A has changed shape to a small circle and blinks off, the second chaff cursor 41B has changed shape to a large circle and blinked off, and the third chaff cursor 41C has changed shape to a smaller circle and turn on Blink.

声音能伴随任何的显示，和所有的显示路径。声音伴随的一个光标路径的显示-包括闪烁和形状改变-可以通过控制光标移动的人所控制。通过介质可以引起声音。对应于伴随一个光标路径的声音的触觉信号能使其被发送到控制光标移动的输入设备。Sound can accompany any display, and all display paths. The display of a cursor path accompanied by sound - including blinking and shape changing - can be controlled by the person controlling the movement of the cursor. Sound can be induced through a medium. Haptic signals corresponding to sounds accompanying the path of a cursor enable it to be sent to an input device controlling cursor movement.

在人和相继的人之间的对称扩展到多个相继的人的所有配对之间的对称。每个经不同的输入设备控制不同的移动。每个经不同的输入设备能控制不同的光标闪烁和光标形状改变。对于每个移动(以及光标闪烁和形状改变，如果存在)，箔条分量能引起无尽的箔条路径的变化，光标和箔条光标闪烁，光标和箔条光标形状改变，以及这些的组合。The symmetry between a person and successive persons extends to the symmetry between all pairs of successive persons. Each controls a different movement via a different input device. Each can control different cursor blinks and cursor shape changes via different input devices. For each movement (and cursor blink and shape change, if present), the chaff component can cause an endless chaff path change, cursor and chaff cursor blink, cursor and chaff cursor shape change, and combinations of these.

数据处理器可以是一个专用目的的数据处理器，可以是通用目的的数据处理器，可以是单独的，可以是网络的一部分，并且在交替的时间间隔中可以是单独的和一个网络的部分。The data processor can be a special purpose data processor, can be a general purpose data processor, can be alone, can be part of a network, and can be both alone and part of a network at alternate time intervals.

计算机可读信号承载介质可以是一个发射的信号，一个数据存储介质，以及一个发射的信号和一个数据存储介质的组合。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.

发射的信号可以是任何的各种点对点的以及能量传输的广播形式-现有技术中公知的无线的和经有线的，电缆，和光纤。信号的部分可以属于发射信号的一个形式，部分可以属于发射信号的第二种形式，以及部分可以属于发射信号的各种组合形式。The transmitted signal can be any of various point-to-point and broadcast forms of power transmission - both wireless and via wire, cable, and fiber optics as known in the art. Portions of the signal may belong to one form of the transmitted signal, portions may belong to a second form of the transmitted signal, and portions may belong to various combinations of transmitted signals.

数据存储介质可以是任何现有技术已知的各种机械的、电的、磁的、光的、分子的、原子的、和量子的数据存储介质，该计算机可读信号的部分可属于数据存储介质，部分可以属于第二数据存储介质，部分可以属于发射的信号，部分可以属于第二发射的信号，并且部分可以属于数据存储介质和发射的信号的各种组合。The data storage medium may be any of various mechanical, electrical, magnetic, optical, molecular, atomic, and quantum data storage media known in the art, and the computer-readable signal portion may belong to the data storage medium The medium, part may belong to the second data storage medium, part may belong to the transmitted signal, part may belong to the second transmitted signal, and part may belong to various combinations of data storage medium and transmitted signal.

尽管一个输入设备被描述成一个常规的计算机鼠标，但可以使用任何输入设备，包括声音激活设备-它被信号连接到一个数据处理器。例如，可以使用在国际专利申请PCTUS0007538和美国专利申请60211471以及60226183中公开的输入设备。Although an input device is described as a conventional computer mouse, any input device may be used, including sound activated devices - which are signally connected to a data processor. For example, the input devices disclosed in International Patent Application PCTUS0007538 and US Patent Applications 60211471 and 60226183 may be used.

光标显示保密产品对于输入私人信息是特别有用的，比如个人身份号码的输入-这里旁观者看到的是其它的信息。在国际专利申请PCTUS0021518和在美国专利申请60226183中公开了几种特定的应用。Cursor display security products are particularly useful for entering private information, such as the entry of a personal identification number - where the onlooker sees other information. Several specific applications are disclosed in International Patent Application PCTUS0021518 and in US Patent Application 60226183.
