Description

  The present invention relates to an input confirmation support apparatus, an input confirmation support method, and an input confirmation support program for confirming important information such as an input password.

  Important information such as passwords can be misused if leaked to a third party. For this reason, when inputting important information in the input field, each character of the character string input as important information is generally replaced with a specific symbol (for example, “●”) and displayed.

  However, when inputting important information in the input field, the method of replacing each character of the character string input as important information with a specific symbol is highly effective in preventing leakage of important information. There is a problem in that it is difficult for the input person to confirm the character string, so that it is difficult to notice an input error of the character string.

  In addition, when a character string is repeatedly input by a malicious third party, the input of the character string as important information is avoided in order to avoid accidentally matching the input character string with the normal character string. In some cases, when a character string different from a regular character string is input a predetermined number of times or more, an apparatus that rejects acceptance of the input character string and stops processing is also known.

  For this reason, even if a user recognizes a regular character string, it is difficult to notice an error in the character input as described above in the method of displaying characters input as important information by replacing them with specific symbols. The input may be repeated, and the acceptance of the character string may be refused, resulting in a situation where the processing is stopped.

In order to solve this, by specifying a character that seems to have been input incorrectly and displaying that character or automatically displaying a part of the character string, it is possible to make an input error without grasping the entire important information. There is known a system for checking whether or not there is (see Patent Document 1).
JP 2005-78472 A

  However, in Patent Document 1, since a part of the character string is completely displayed on the display, a part of important information is also revealed to a third party who looks into the display. Therefore, when a character string constituting this important information is repeatedly input by a malicious third party, the possibility that the input character string coincides with a regular character string increases.

  In addition, when a character string that is easy to guess is used for important information, there is a problem that it becomes easy to guess the entire important information by using the technique of Patent Document 1 several times.

  Further, Patent Document 1 has a problem that, after displaying a part of characters of important information, if the action of returning the display is not performed, the characters remain displayed.

  An object of the present invention is made in view of the above points, and provides an input confirmation support apparatus, an input confirmation support method, and an input confirmation support program capable of ensuring high security and easily confirming important information. It is in.

  In order to achieve the above object, the input confirmation support apparatus according to claim 1 converts a character string input means for inputting a character string into an input screen, and a character string input by the character string input means into another symbol. First display information control means to be displayed on the input screen, scratch means for scratching the converted symbol, transmission means for transmitting a portion scratched by the scratch means, and the transmission information corresponding to the transmitted portion And a second display information control means for displaying characters input by the character string input means on the input screen.

  An input confirmation support method according to an eleventh aspect and an input confirmation support program according to a twelfth aspect are characterized by causing a computer to execute an operation similar to that of the input confirmation support apparatus according to the first aspect.

  According to the present invention, the input character string is converted into another symbol, and when the converted symbol is scratched, the scratched portion is transmitted, and the input character corresponding to the transmitted portion is transmitted. Displayed on the input screen. In this way, since only the person who entered the important information can display the input content, the important information can be confirmed within a range that is not problematic even if viewed by a third party. Accordingly, it is possible to easily confirm important information while ensuring high security.

  Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
FIG. 1 is a block diagram showing a configuration of an information processing apparatus as an input confirmation support apparatus according to the first embodiment of the present invention.

  The information processing apparatus 100 of FIG. 1 includes a CPU 101, a ROM 102, a RAM 103, an external memory 104, an input device 105, a display device 106, and a communication interface 107. These are connected to each other via a system bus 108.

  The CPU 101 controls each device based on a program stored in the program ROM in the ROM 102 and controls the entire information processing apparatus 100. The ROM 102 includes a font ROM area for storing font data and the like, and a data ROM for storing various data. The RAM 103 functions as a main memory, work area, and the like for the CPU 101. The external memory 104 includes, for example, a hard disk (HD), a flexible disk (FD), a CD-ROM, a DVD-ROM, and the like.

  The input device 105 is a keyboard that can input an ID or password, a mouse that can be dragged on the screen using a pointing device, or the like. A display device 106 can display an authentication screen and other various displays. Reference numeral 107 denotes a communication interface which controls communication with other information processing apparatuses on the network via a LAN using a predetermined protocol.

  FIG. 2 is a schematic configuration diagram of a network including the information processing apparatus of FIG.

  The information processing apparatus 100 is communicably connected to the server apparatus 200 via the communication network 300.

  The server apparatus 200 has the same configuration as that of the information processing apparatus 100 in FIG. 1 and includes a CPU 201, a ROM 202, a RAM 203, an external memory 204, an input device 205, a display device 206, and a communication interface 207. ing. These are connected to each other via a system bus 208. The external memory 204 includes a database (DB) that stores an ID and password for an authentication operation described later, and also includes a program that performs the authentication operation. Needless to say, the DB for authentication operation of the server device and the program for performing the authentication operation may be provided in the external memory 104 of the information processing apparatus 100.

  FIG. 3 is a flowchart showing authentication processing executed by the information processing apparatus 100 of FIG. This corresponds to password input executed by the CPU 101 shown in FIG. 1 based on a program stored in the ROM 102.

  First, in step S301, an authentication screen as shown in FIG. 4 is displayed on the display device. Although not shown in this flowchart, it is assumed that the user ID is input by the user in the ID input field 401 of FIG. 4 as “m_kan”.

  Next, in step S302, an input character corresponding to the password is acquired. This acquisition method may be input from the user using a keyboard, or may be input temporarily stored data such as Cookie used on the Web.

  The input characters are displayed as special symbols (in the case of FIG. 4, ●) as shown in the password input field 402 of FIG. 4 (step S303). Although the ID input field 401 and the password input field 402 are displayed on the authentication screen in FIG. 4, only one of the input fields may be displayed. In this case, only the step corresponding to the displayed input field is executed.

  After a special symbol is displayed in the password input field 402 in step S303, whether the OK button 403, the cancel button 404 is pressed, or the OK button 403 and the authentication screen in FIG. It is determined whether or not a mouse operation other than pressing the cancel button 404 has been performed (step S304).

  If a mouse operation other than pressing the OK button 403 and the cancel button 404 is performed in step S304, the process proceeds to step S305.

  In step S305, it is determined whether or not the mouse pointer has been dragged or clicked on the scratched area. The scratched area is an area corresponding to a special symbol (in the case of FIG. 4) displayed in the password input field 402.

  If the mouse pointer has not been dragged or the mouse has not been clicked, the process returns to step S304. On the other hand, if the mouse pointer is dragged or the mouse is clicked, digital scratch processing is executed (step S306), and the process returns to step S304. The digital scratch is an input hidden through the special symbol when the mouse pointer passes over the special symbol displayed in the password input field 402 (in the case of FIG. 4), and the trajectory is passed. This is a process of displaying characters, the details of which will be described later. In addition to the above drag, the mouse pointer is moved (moved) while the left and right buttons of the mouse are pressed, and the mouse pointer is moved (moved) without pressing the left and right buttons of the mouse. Including cases.

  If the cancel button 404 is pressed in step S304, the authentication process is stopped (step S307).

  If the OK button 403 is pressed in step S304, an authentication operation is performed (step S308). In this authentication operation, it is determined whether or not the ID and password registered in the DB of the server apparatus 200 or the DB of the information processing apparatus 100 match the ID and password input in steps S301 and S302. When authenticating with the ID and password registered in the DB of the server apparatus 200, the CPU 201 receives the ID and password output from the communication interface 107 via the communication interface 207 of the server apparatus 200, and receives the received ID and password. It is determined whether the received ID and password match the ID and password registered in the DB of the external memory 204, and the result is transmitted to the information processing apparatus 100 via the communication interface 207.

  In step S309, it is determined whether or not the authentication result is OK. If the authentication result is OK, this process is terminated, and if the result is not OK, the process returns to step S302.

  FIG. 5 is a flowchart showing the digital scratch process in step S306 of FIG. This corresponds to the digital scratch processing operation executed by the CPU 101 shown in FIG. 1 based on the digital scratch processing program stored in the ROM 102.

  First, in step S501, the range in which the mouse pointer is dragged (that is, the scratched portion) and the mouse pointer drag speed (that is, the scratch speed) are measured.

  FIG. 6 is a schematic diagram showing the scratch width and the scratched area. Reference numeral 601 in FIG. 6 denotes a scratched area (special symbol (●)). Hereinafter, moving or dragging on the scratched area 601 with a mouse pointer or a finger, or clicking on the scratched area is referred to as scratch. Reference numeral 602 denotes a trajectory (scratch trajectory) when a mouse pointer (not shown) passes over the scratched area 601. A white portion 603 around the locus 602 indicates a transmission width (scratch width) on the scratched area 601. That is, when the scratch is executed, the input character hidden under the transparent width 603 can be seen through. The width and the transmittance of the scratch change in accordance with the drag speed of the mouse pointer. FIG. 7A shows the relationship between the scratch width and transmittance and the drag speed of the mouse pointer (that is, the scratch speed). Information on the drag speed of the mouse pointer is acquired from the OS. Also, either the scratch width or the transmittance may be changed depending on the drag speed of the mouse pointer, both may be changed, or both may not be changed.

  Next, in step S502 of FIG. 5, the transmission range or transmittance of the scratched area is determined based on the result measured in step S501. More specifically, the slower the drag speed of the mouse pointer is, the higher the transmittance is or the larger the range of transparency is made easier to see.

  For example, when the mouse pointer 801 shown in FIG. 8A is quickly dragged along a locus 602 in FIG. 6, the transmittance of the scratched area 802 is lowered as shown in FIG. Set difficult. On the other hand, when the mouse pointer 801 shown in FIG. 8B is slowly dragged, the transmittance of the scratched area 802 is increased as shown in FIG. 8B, and the scratched area 802 in FIG. Compared to easy-to-read settings.

  Further, for example, when the mouse pointer 801 shown in FIG. 9A is quickly dragged along a locus 602 in FIG. 6, the transmission range of the scratched area 802 is reduced (the scratch width is reduced) Set it more difficult to see. On the other hand, when the mouse pointer 801 shown in FIG. 9B is slowly dragged, the transmission range of the scratched area 802 is increased as shown in FIG. 9B, and the scratched area 802 in FIG. Compared to, set to be easier to see.

  Next, in step S503 of FIG. 5, the scratched area to which the mouse pointer is dragged is transmitted by the transmittance, and the input character obtained in step S302 is displayed.

  In step S504, time counting is started by the scratch timer. The scratch timer is realized based on the OS system time stored in the ROM 102 by the CPU 101. In step S505, it is determined whether or not the scratch timer has reached a predetermined time (for example, 15 seconds). This predetermined time can be set by the CPU 101.

  If the scratch timer has not reached the predetermined time, the determination is repeated. On the other hand, if the scratch timer has reached the predetermined time, the transmission of the scratched area that was transmitted in step S503 is canceled, and the original target is recovered. The display is returned to the display of the scratch area (display of the special symbol (●) that is not transmitted) (step S506), and this process ends.

  As described above in detail, according to the present embodiment, when the input password is converted into a special symbol (●) and the converted special symbol (●) is scratched, the scratched portion is The password is transmitted and the password corresponding to the transmitted portion is displayed on the input screen. In this way, only the person who entered important information such as a password can display the screen only to the point where the input content can be confirmed, so it is possible to confirm important information within a range that is not problematic even if seen by a third party. it can. Accordingly, it is possible to easily confirm important information while ensuring high security.

  Further, since the transmission time of the scratched portion can be set, a password corresponding to the portion that has been transmitted unnecessarily forever is not displayed on the input screen, and high security can be ensured.

  Furthermore, since the scratch width or transmittance is changed according to the drag speed of the mouse pointer (that is, the scratch speed), the person who has input important information such as a password can change the scratch width or The transmittance can be adjusted.

While the scratch operation continues (for example, when the mouse pointer continues to move without stopping or when the mouse click button is continuously pressed), the time is counted by the scratch timer in step S504. The time count may be started by the scratch timer at the time when the scratch operation is finished (for example, when the mouse pointer stops or when the mouse click button is released) without starting. Thereby, while the user wants to confirm the password, the permeation of the scratched area is continued, so that the user's usability is further improved.
(Second Embodiment)
In the first embodiment, the scratch width and transmittance are determined according to the drag speed of the mouse pointer, but in this embodiment, the number of times the mouse trajectory enters the scratched area ( The scratch width and transmittance are determined according to the number of scratches).

  Hereinafter, a second embodiment will be described with reference to FIGS.

  Since the information processing apparatus according to the present embodiment is the same as the configuration of the information processing apparatus 100 according to the first embodiment, description thereof is omitted. Since the authentication process is the same, description thereof is omitted.

  FIG. 10 is a flowchart showing digital scratch processing executed by the information processing apparatus 100 according to the second embodiment of the present invention. This corresponds to the digital scratch processing operation executed by the CPU 101 shown in FIG. 1 based on the digital scratch processing program stored in the ROM 102. This digital scratch process corresponds to the process of step S305 in FIG.

  Steps S1003 to S1006 in FIG. 10 are the same as steps S503 to S506 in FIG.

  First, in step S1001, the number of scratches in the scratched area where the mouse pointer is dragged, the range where the mouse pointer is dragged, and the drag speed of the mouse pointer are measured. The number of scratches means the number of times that the mouse trajectory enters and exits the scratched area.

  FIG. 11 is a diagram showing the relationship between the number of scratches and the scratched area.

  Reference numeral 1101 in FIG. 11 denotes a scratched area (special symbol (●)). Hereinafter, dragging on the scratch area is referred to as scratch.

  Reference numeral 1102 denotes a locus of a mouse pointer (not shown) passing through the scratched area. In the case of FIG. 11, the number of scratches is four. A white portion 1103 where the trajectory 1102 and the scratched area 1101 overlap indicates a transmission width (scratch width) on the scratched area 1101. Similar to the first embodiment, the width and the transmittance of this scratch change in accordance with the number of scratches. The relationship between the scratch width and transmittance and the number of scratches is shown in FIG.

  In step S1102, the transmission range or transmittance of the scratched area is determined based on the result measured in step S1101. Specifically, the greater the number of scratches, the higher the transmittance, or the range of transmission is made easier to see.

  For example, when the mouse pointer 801 shown in FIG. 12A is scratched only four times as shown by the locus 804, the transmittance of the scratched area 802 is lowered as shown in FIG. To do. On the other hand, when the mouse pointer 801 shown in FIG. 12B performs two sets of scratches four times as indicated by the locus 805, the transmittance of the scratched area 803 is increased as shown in FIG. It is set to be easier to see than the scratched area 802 of 8 (A). In this case, the two sets of scratches on the locus 805 are not displayed in a superimposed manner for convenience of explanation, but actually, it is assumed that they are scratched in a superimposed manner.

  Also, for example, when the mouse pointer 801 shown in FIG. 12A is scratched only four times as shown by a locus 804, the transmission range of the scratched area 802 is reduced as shown in FIG. 9A (scratch). Set the width to be more difficult to see. On the other hand, when the mouse pointer 801 shown in FIG. 12B performs two sets of scratches four times as indicated by a locus 805, the transmission range of the scratched area 803 is increased as shown in FIG. Compared with the scratched area 802 in FIG.

  As described above in detail, according to the present embodiment, the same effects as those of the first embodiment can be obtained.

  Further, since the width or transmittance of the scratch is changed according to the number of scratches, the person who has input important information such as a password can adjust the width or transmittance of the scratch according to the situation to be confirmed.

(Third embodiment)
In the first embodiment, when the scratch timer reaches a certain time, the permeation of the scratched area that has been permeated is canceled (step S506), but in the present embodiment, the permeation is permeated. The transmittance of the scratched area is sequentially decreased in the order of scratching. That is, the display of the scratched area that has been transmitted is returned to the original display of the scratched area (display of the special symbol (●) that is not transmitted) in order as time elapses.

  Hereinafter, a third embodiment will be described with reference to FIGS.

  Since the information processing apparatus according to the present embodiment is the same as the configuration of the information processing apparatus 100 according to the first embodiment, description thereof is omitted. Since the authentication process is the same, description thereof is omitted.

  FIG. 13 is a flowchart illustrating digital scratch processing executed by the information processing apparatus 100 according to the third embodiment. This corresponds to the digital scratch processing operation executed by the CPU 101 shown in FIG. 1 based on the digital scratch processing program stored in the ROM 102. This digital scratch process corresponds to the process of step S305 in FIG.

  First, in step S1301, it is confirmed that scratching has started, and data relating to the scratched area scratched in step S1302 is temporarily stored in the work area of the RAM 103, and the transmittance of the area is set to a fixed value (for example, 24%). ) Only increase. Thereby, the input character hidden in the area is displayed.

  Here, data temporarily stored in the work area of the RAM 103 will be described with reference to FIG.

  FIG. 14 is a diagram schematically showing the relationship between screen coordinates, elapsed time, and transmittance.

  In FIG. 14, the X coordinate 1401 and the Y coordinate 1402 indicate the coordinates on the display screen of the scratched area to be scratched, the elapsed time 1403 indicates the elapsed time since the scratch was started, and the transmittance 1604 indicates the corresponding coordinates. The transmittance is shown. The data in FIG. 14 is temporarily stored in the work area of the RAM 103.

  In FIG. 14, the coordinates (X, Y) are (102, 101) → (101,101) → (100,102) → (100,103) → (101,102) → (102,102) → (102, 101) shows the case of scratching in the order.

  FIG. 15 is a diagram schematically showing the relationship between coordinates and transmittance on the display screen of the scratched area.

  Column number 1503 indicates the X coordinate on the display screen of the scratched area, and row number 1504 indicates the Y coordinate on the display screen of the scratched area. The numerical value in% display in FIG. 15 indicates the transmittance when the mouse pointer 1501 is moved along the line 1502. The movement of the mouse pointer 1501 in FIG. 15 corresponds to the temporarily stored data in FIG.

  Returning to FIG. 13, in step S1303, it is determined whether or not the transmittance of the scratched area to be scratched is 0%.

  If the transmittance of the scratched scratched area is 0% in step S1303, the process proceeds to step S1305.

  In step S1303, when the transmittance of the scratched scratched area is not 0%, the transmittance is decreased by a constant rate (for example, 4%) every predetermined time (step S1304). FIG. 14 shows a case where the transmittance is reduced by 4% every second.

  Next, in step S1305, it is determined whether or not the scratch has ended. Whether or not the scratch has ended is determined, for example, by whether or not the mouse pointer has stopped for a predetermined time or the mouse click button has been released.

  In step S1305, if the scratch has been completed, the transmittance of all the scratch areas is set to 0%, that is, the display of the original scratched area is displayed (display of the special symbol (●) that is not transmitted). Then, this process ends.

  If it is determined in step S1305 that scratching has not ended, it is determined whether or not the transmittance check has been completed for all scratched areas that have been scratched (step S1307).

  If it is determined in step S1307 that the transmittance has been checked in all scratched areas that have been scratched, the process returns to step S1302. On the other hand, if the transmittance check has not been completed in all scratched areas that have been scratched, the process returns to step S1303.

  In step S1306, the transmittance of all the scratch areas is set to 0% when the scratch is completed. However, in step S605, the transmittance of steps S603 and S604 is increased until the transmittance becomes 0% regardless of the end of the scratch. You may perform a process.

  FIG. 16 is a diagram illustrating an example of an authentication screen when a predetermined time has elapsed since the scratch was started.

  When the mouse pointer 1601 moves like a locus 1602, each part of the scratched area that is scratched is transmitted by a certain percentage.

  In addition, each transmitted portion of the scratched scratched area reduces the transmittance by a certain amount when a certain time has elapsed. As a result, a portion having a different transmissivity occurs as shown by 1603 in FIG. 16, and it becomes difficult to see over time.

  As described above in detail, according to the present embodiment, the same effects as those of the first embodiment can be obtained.

  Also, since the transmittance of the scratched portion decreases according to the elapsed time from the start of scratching, the password corresponding to the portion that has been transmitted unnecessarily will not be displayed on the input screen, and is high Security can be ensured.

(Fourth embodiment)
In the first to third embodiments, the scratched area in the scratched range is set to pass through the scratched area that has been scratched. Only pass the part where the password and the entered password are different.

  Since the information processing apparatus according to the present embodiment is the same as the configuration of the information processing apparatus 100 according to the first embodiment, description thereof is omitted. Since the authentication process is the same, description thereof is omitted.

  FIG. 17 is a flowchart illustrating digital scratch processing executed by the information processing apparatus 100 according to the fourth embodiment. This corresponds to the digital scratch processing operation executed by the CPU 101 shown in FIG. 1 based on the digital scratch processing program stored in the ROM 102. This digital scratch process corresponds to the process of step S305 in FIG.

  In step S1701, it is confirmed that scratching has started, and in step S1702, a regular password is received from the server apparatus 200 via the communication network 300. When a regular password is registered in a DB (not shown) stored in the external memory 104 of the information processing apparatus 100, the regular password is read from the DB.

  In step S1703, it is determined whether or not the number of characters different between the input password and the regular password is equal to or less than a threshold value (10% or less of the number of characters of all passwords or one character).

  If the number of characters different between the input password and the regular password is greater than the threshold value in step S1703, it is determined that the access is unauthorized and the digital scratch process is terminated.

  If the number of characters different between the input password and the regular password is equal to or smaller than the threshold value in step S1703, the character position different between the received password and the input password is temporarily stored in the work area of the RAM 103 in step S1704. .

  Next, in step S1705, it is determined whether or not the scratch has ended. Whether or not the scratch has ended is determined, for example, by whether or not the mouse pointer has stopped for a predetermined time or the mouse click button has been released.

  If the scratch has ended in step S1705, the process advances to step S1708 to cancel the transmission of the scratched area that has been transmitted, and display the original scratched area display (a special symbol that is not transmitted (● ) Display) (step S1708), and the process is terminated.

  If it is determined in step S1705 that the scratch has not ended, it is determined in step S1706 whether the scratch has been performed in the scratched area corresponding to the character position stored in step S1704.

  In step S1706, if the scratch is not performed in the scratched area corresponding to the character position stored in step S1704, the process returns to step S1705.

  In step S1706, when the scratch is performed in the scratched area corresponding to the character position stored in step S1704, in step S1707, out of the scratched range, the object corresponding to the character position stored in step S1704. Only the scratch area is transmitted, and the process returns to step S1705.

  18A is a diagram illustrating an example of an authentication screen in the information processing apparatus 100, and FIG. 18B is a diagram illustrating another example of the authentication screen in the information processing apparatus 100.

  Note that an accurate password (in the case of FIGS. 18A and 18B, “minako”) is stored in the DB of the server 200, and the information processing apparatus 100 has received the password.

  FIGS. 18A and 18B show a case where the user erroneously inputs “mimako” when the user has to input “minako”. When the user once authenticates and cannot authenticate, the user moves the mouse pointer 1801 so as to lick the entire scratched area as shown by a locus 1802 as shown in FIG. As a result, as shown in the scratched area 1803, only one character and a part of the erroneous character appear, and if only that character is corrected, authentication can be performed. In this case, it may be displayed only when the input error is one character or less than 20% of all characters.

  On the other hand, in FIG. 18B, when the user cannot authenticate once, the process proceeds to digital scratch processing by pressing a button (not shown) of the input device 105. In FIG. 18B, an exposed area 1804 on the line is shown on the authentication screen. Using the left and right keys (not shown) of the cursor keys of the input device 105, the exposed area 1804 on the line is moved to the left and right, and the password is displayed by changing the exposed area. In this case as well, only characters different from the regular password may be displayed as in the exposed area 1805 on the line.

  As described above in detail, according to the present embodiment, the same effects as those of the first embodiment can be obtained.

  Moreover, since only characters different from the regular password are displayed, higher security can be secured and important information can be easily confirmed.

  In the first to fourth embodiments, the scratch is performed by dragging the mouse pointer as the digital scratch process, but the digital scratch process may be realized by a click operation. For example, as shown in FIG. 19A, when the scratched area 1902 is clicked with the mouse pointer 1901, the CPU 101 transmits the clicked scratched area 1902 as shown in FIG. 19B. In this case, the CPU 101 may change the transparency of the clicked scratched region according to the number of clicks, such as increasing the transmittance by 4% for each click.

  In addition, when the mouse pointer is clicked, when the pressure sensitive device is clicked with a finger or when any button is pressed, if the entered character is different from the password, the entire character different from the password May be displayed for a moment (for example, the transmittance is 100% only for 2 seconds). In that case, it is desirable that the number of matching characters in the password is greater than a certain threshold.

  When the input device 105 is a pressure-sensitive device, the transmission range or transmittance of the scratched area may be changed according to the pressure pressed by the user.

  In the first to fourth embodiments, the CPU 101 can set the transmission range or transmittance of the scratched area. In particular, in the first to fourth embodiments, the scratching process has been described. However, a transmission range or transmittance can be set in order to restore the scratched area to be scratched. For example, by dragging the scratched scratched area while pressing the Ctrl key, it is possible to set the 4% transmittance to be lowered for each drag.
