Compared with the general e-commerce system (or e-commerce platform), online banking is the most demanding online trading system, because online banking only needs users to open a web page to enter an account/password. You can log in to make an EFT transaction, which is extremely risky. Since 2006 and 2010, South Korea and the mainland have required online banking to protect the security of users' passwords. Therefore, an anti-keyboard recording system must be installed on the client's computer. Taiwan is in the new network in 2013. The bank’s security control benchmark incorporates “security measures that financial institutions should be able to prevent passwords from being recorded”. It can be seen that the input security of the account/password is an important issue for the security. In this era of hackers and Trojans, the prevention of keyboard side recording, network side recording, Trojan horse programming and other technologies is a very important security link.

Therefore, many prior art techniques for preventing the virtual keyboard of the keyboard from being recorded are born. The prior art method is nothing more than randomly changing the position of the virtual button, so that the malicious program cannot side-record the correct character. However, the prior art has no Fixed order rules, random settings, virtual buttons The position of the key causes the user to spend time looking for a button, which is quite inconvenient to use, meaning that the prior art cannot satisfy the user's habitual operation. Therefore, it is necessary to improve the resources of the prior art hardware and software to work together to propose a dynamic virtual numeric keypad technology that conforms to the habitual operation of the user, so that the numerical keyboard layout has a certain order for the user to follow and can be randomized.

The remaining module functions of the device 10 are the same as those of the first figure. However, the screen 16 has no touch function, so no further details are provided.

Referring to FIG. 3A, FIG. 3 is a schematic diagram (1) of a virtual numeric keypad 20 according to an embodiment of the present invention. The keyboard layout of the virtual numeric keypad 20 according to an embodiment of the present invention includes: a first keypad 26 (in the figure) The dashed box) and the second keypad 30 (the dotted box in the legend). In order to facilitate the description of the keyboard layout of the embodiment of the present invention, a dotted box is specially drawn in the figure, and the dotted frame is not displayed in the actual screen 16 screen. In addition, the legend is particularly widened in order to draw the dotted square box. The interval between the keypad 26 and the second keypad 30 should have a uniform upper and lower spacing in each of the actual screens of the screen 16.

The first keypad 26 of the present embodiment has a space of at least 3 by 3 for accommodating at least nine digits of virtual keys. The nine virtual keys in the first keypad 26 are referred to as the first key group 28, while the first key group 28 of the present invention comprises two permutations. The first permutation combination is in the form of a telephone button (ITU-T E.161 International Standard Specification) arranging nine numbers, from left to right, top to bottom in the order of "1, 2, 3, 4, 5, 6, 7, 8, and 9", ie, The first row is "1, 2, 3", the second row is "4, 5, 6", and the third row is "7, 8, 9", as shown in Figure 3A. The second permutation combination is arranged in a computer button style with nine numbers, which are from left to right and from top to bottom in the order of "7, 8, 9, 4, 5, 6, 1, 2 and 3", ie, One row is "7, 8, 9", the second row is "4, 5, 6", and the third row is "1, 2, 3", as shown in Figure 3B. Each time the virtual numeric keypad 20 of the present invention is executed, the processor 12 selectively arbitrarily selects the first permutation combination of the telephone button patterns or the second permutation combination of the computer button patterns as the first key group of the virtual numeric keypad 20 layout. Since the order of the phone button style and the arrangement of the computer button styles are not unfamiliar to the user, both are the order of the numbers that are often seen in daily life, so that the user has certain key position setting rules to follow. Quickly click on the virtual button to enter the number.

The second keypad 30 of the present invention includes at least one button space for accommodating a digital virtual button of the second key group 32, that is, "0".

Each time the virtual numeric keypad 20 of the present invention is executed, the processor 12 randomly selects one to a plurality of buttons in each row of the first key group 28 in the first keypad 26 in a random manner, and the "selected" are randomly selected. The button "enlarges the width of the button. Another method of random selection is to randomly select one to a plurality of keys from the nine keys of the first key group 28 in the first keypad 26, and to enlarge the "selected keys" to enlarge the button width. As for the second key group 32 in the second keypad 30, if there is only one numeric key ("0"), the processor 12 randomly determines whether to enlarge the key width of "0". The first embodiment (as shown in FIGS. 3A and 3B) is randomly selected from each row of the first key group 28 in the first keypad 26, and the second key group 32 in the second keypad 30 is randomly selected. Decide whether to choose “0” (when there is only one button). Taking FIG. 3A as an example, the “keys randomly selected” in each row of the first key group 28 is “1” (ie, “3” in the first row, “4” in the second row, and “fourth” in the second row. The "9" of the three rows, and the "randomly selected button" of the second key group 30 is also "1" (ie, "0"). In this embodiment, the "randomly selected keys" of all the key groups (or all the keypads) have the same button width, that is, the button widths of "3", "4", "9", and "0" All the same. In some embodiments, in the same key group (or the same keypad), randomly selected keys have the same button width, and different key groups may have different button widths, for example: first key group 28 The buttons of "3", "4" and "9" have the same width, and the "0" of the second key group 32 is different from the button width of the above three, as shown in Fig. 4A. The present invention further sets a "key adjustment number preset value" (hereinafter referred to as "adjustment quantity") to control "the number of randomly selected keys". In this embodiment, the number of adjustments of each row of each key group is set as: "The number of adjustments is equal to 1" ("Adjustment Quantity = 1").

The first key group 28 of the present invention selects the first permutation combination or the second permutation combination in a random manner by the processor 12, and selects the keys in each of the key groups in a random manner and enlarges the button width thereof, the purpose of which is to randomly adjust the virtual In the click area of the button, even if the malicious program has recorded all the click coordinates, the correct character (ie, the button) cannot be reversed by the coordinates. That is, the same click coordinates, i.e., (X, Y), in the virtual numeric keypad 20 of the present invention, each time the processor 12 executes and is displayed on the screen 16, will represent different keys (i.e., characters). Again, taking FIG. 3A as an example, it is assumed that the device 10 that executes the virtual numeric keypad 20 of the present invention is a smart phone with a screen resolution of 1920×1080. The coordinates of a point in the "1" button in the legend are assumed to be (100, 575). When the next time the processor 12 executes the virtual numeric keypad 20, it is possible that the second permutation combination is selected as the first The keyboard layout of the key group 28 (as shown in FIG. 3B), that is, the arrangement order of "7". At this time, the coordinate position (100, 575) is not in the "1" button, even if the first permutation combination is selected as the keyboard layout of the first key group 28, that is, the arrangement order of "1", but the processor 12 is random. After selecting and enlarging the button widths of a certain button (or some buttons) of each row in the first key group 28, the coordinate position (100, 575) of the point is still most likely not in the "1" button. This technology allows the click coordinates recorded by the malicious program to reversely calculate the correct characters, and the buttons are still arranged in the order of the traditional computer button style or phone button style, so that the user can find according to their usage habits. The location of the button.

The first key group 28 and the second key group 32 of the present invention are only used to specify the order of ten numeric keys in the key group. The present invention does not limit the function keys and the special symbol keys to be set in a specific key area. , function keys such as: "Enter" (Enter, can also be marked as "confirm" or "OK"), "Shift", "reverse button", etc., as for "special symbol keys" such as: At (@) The bottom line (_), the space key (Space), the decimal point (.), etc. may be arbitrarily combined to the first keypad 26 or the second keypad 30 by hand. That is, a software developer or other manufacturer applying the method of the present invention can insert function keys and special symbol keys into any of the keypads according to their needs. In some embodiments, when the present invention randomly selects a button in each row of each key group and adjusts the button width, the function key/special symbol key can be excluded without adjustment, that is, the function key/special symbol key The fixed button width is maintained; in some embodiments, the function keys/special symbol keys are responsible for the associated key group, and are also among the randomly selected lists, that is, the function keys/special symbol keys are randomly selected and adjusted.

Referring to FIG. 3B, a schematic diagram (2) of a virtual numeric keypad 20 according to an embodiment of the present invention is different from FIG. 3A in that the first key group 28 of the legend is a second permutation combination (ie, a computer press Key style), from left to right, from top to bottom, "7, 8, 9, 4, 5, 6, 1, 2, and 3", that is, the first row is "7, 8, 9". The second row is "4, 5, 6" and the third row is "1, 2, 3".

Referring to FIGS. 4A and 4B, a schematic diagram of a virtual numeric keypad 20 in accordance with a second embodiment of the present invention illustrates that the virtual numeric keypad 20 includes a presentation box 42 in addition to the first keypad 26 and the second keypad 30. In the application development, a label element 42 or an input box (Input Box) is used to implement the presentation box 42. The presentation box 42 is used to temporarily display the “pointed” after the user clicks the virtual button. Select the character corresponding to the button." In addition, before the user operates the virtual numeric keypad 20, the presentation box 42 can also be used to display an operation prompt (Operation Tips), for example, "press OK when the input is completed" in the legend, when the user starts clicking the virtual button, the operation is performed. The prompt is automatically cleared. The second keypad 30 of the present embodiment elastically expands the space to accommodate function keys (ie, "reverse key" and "OK key" in the legend) and special symbol keys (ie, "decimal point" in the legend). Go to the second key group 32. When the second keypad 30 elastically amplifies one to a plurality of spaces to accommodate the added function keys or/and symbol keys, so that the second key group 32 has a plurality of keys, the processor 12 is in a random manner in the second key group. 32 Select one to a plurality of buttons, and enlarge the "selected buttons" to enlarge the button width. The function of the "confirmation key" (ie, the "OK key" in the legend) is that after the user inputs, the "character corresponding to the button that has been clicked" will be displayed (ie, the character string displayed by the presentation box 42). ) is transferred to the digital input box 40 of the application 22. The first key group 28 of Fig. 4A is a first permutation combination, and the first key group 28 of Fig. 4B is a second permutation combination.

Referring to FIG. 5A and FIG. 5B, a schematic diagram of a virtual numeric keypad 20 according to the third embodiment of the present invention, the first keypad 26 and the second keypad 30 are both elastically expandable to accommodate function keys or special Symbol keys, while function keys can be of different sizes (including width and height). In this embodiment, a function key is added to the right side of the first two rows of the first keypad 26, and a special symbol key and another function key are added to the right side of the second keypad 30. The function key/special symbol of this embodiment The keys can be set to be excluded from the random selection list of the processor 12 (i.e., with a fixed button width), or can be set to be randomly selected by the processor 12. The first key group 28 of Fig. 5A is a first permutation combination, and the first key group 28 of Fig. 5B is a second permutation combination. In some embodiments, the function keys are randomly adjusted by the processor 12 to set the position, for example, the "reverse button" of Figure 5A is at the first keypad 26, the "OK button" is at the second keypad 30, and the fifth panel is The "OK button" is in the first keypad 26 and the "reverse button" is in the second keypad 30. This setting sequence is randomly set by the processor 12 to increase the variable of the virtual button corresponding to the click region. In this embodiment, the number of adjustments of each row of the first key group 26 and the adjustment amount of the second key group 32 are set to: “the number of adjustments is an arbitrary number greater than or equal to 1” (“adjustment quantity>=1”), and Some of the randomly selected buttons are enlarged and reduced so that all the buttons are not equal in width (ie, each row can have a plurality of button widths).

Referring to FIG. 6A and FIG. 6B, a schematic diagram of a virtual numeric keypad 20 according to an embodiment of the present invention. This embodiment illustrates that the first keypad 26 can elastically expand the space to accommodate the third keypad 34, and the third keypad. 34 is for accommodating a third key group 36 including function keys. The first key group 28 of Fig. 6A is a first permutation combination, and the first key group 28 of Fig. 6B is a second permutation combination. The third key group 36 of the present embodiment is not among the random selection lists of the processor 12, that is, the third key group 36 adopts a fixed button width. In some embodiments, the function keys in the third key group 36 are randomly adjusted by the processor 12 in an up-and-down order, for example, the "reverse key" of FIG. 6A is above, the "OK key" is below, and the The OK button is "above" and the "reverse button" is below. This setting sequence is randomly set by the processor 12 to increase the variable of the virtual button corresponding to the click area. In addition, in this embodiment, the row adjustments of the first key group 26 are The amount of adjustment of the quantity and the second key group 32 is set to: "the number of adjustments is equal to 1" ("adjustment number = 1"), and all of the randomly selected keys have the same button width (ie, "3", "4") The widths of the buttons of "9" and "0" are equal).

Referring to FIG. 7A and FIG. 7B, FIG. 7 is a schematic diagram of a virtual numeric keypad 20 of the embodiment of the present invention. This embodiment illustrates that the third keypad 34 is disposed in the first keypad 26 and the second keypad 30 in the virtual numeric keypad 20. Right. The first key group 28 of Fig. 7A is a first permutation combination, and the first key group 28 of Fig. 7B is a second permutation combination. Similarly, the function keys in the third key group 36 are randomly adjusted by the processor 12 in the upper and lower order, for example, the "reverse key" of the 7A picture is above, the "OK key" is below, and the "OK key" of the 7B figure. At the top, the "reverse button" is below. Different from all the above embodiments, this embodiment reduces the button widths of the "randomly selected keys".

In some embodiments, the third set of program instructions randomly selects one to a plurality of virtual keys in the first key group 28 in a random manner, and enlarges or reduces the button width by "randomly selected keys." After the third program instruction set is adjusted, the first key group 28 has a plurality of key widths.

Step S109: The processor 12 randomly selects the virtual button of the second key group 30 to adjust the width. After the virtual button of the first key group 28 adjusts the width, the third program instruction group causes the processor 12 to select the virtual key of the second key group 30 in a random manner to adjust the button width. In some embodiments, when the second key group 30 has only one "0" key, the third program command group determines whether to adjust the button width in a random manner. In some embodiments, when the second key group 30 has a plurality of virtual keys, the third program instruction group randomly selects one to the plurality of virtual keys of the second key group 30 in a random manner, and then according to the screen 16 obtained in step S103. The resolution is calculated, and the "keys that are randomly selected" are enlarged to the width of the button. In some embodiments, when the second key group 30 has a plurality of virtual keys, the third program instruction group randomly selects one to the plurality of virtual keys in the second key group 30, and then calculates according to the resolution of the screen 16. Reduce the button width by "randomly selected buttons". In some embodiments, when the second key group 30 has a plurality of virtual keys, the third program instruction group randomly selects one to the plurality of virtual keys in the second key group 30 in a random manner, and the “randomly selected keys” are added. Zoom in or out on the button width. When the second key group 30 has a plurality of virtual keys, the third program command group is adjusted so that the second key group 30 has a plurality of key widths.

Step S110: After reading the function keys in the memory 14 and setting them in the virtual numeric keypad 20, the second program instruction group reads the function keys stored in the memory 14 and sets them on the virtual numeric keypad 20. In some embodiments, the function key is selected from the group consisting of: a back button, a confirmation button, and a toggle button. In some embodiments, the function key refers to a third key group 36, and the second program command set sets the third key group 36 to the third keypad 34 in the first keypad 26. In some embodiments, the second set of program instructions sets the function keys to the second keypad 30. In some embodiments, the second set of program instructions sets the function keys to the first keypad 26 and the second keypad 30, respectively. In some embodiments, the function key is a third key group 36, and the second program command set sets the third key group 36 to the first keypad 26 and the third keypad 34 on the right side of the second keypad 30. In some embodiments, this step is performed after step S107, so that when the third program randomly selects the first key group 26 or the second key group 30, the function key or the third key group 36 is also in the random selection list. in. In some embodiments, when there are a plurality of function keys, the processor 12 randomly reverses the position of the function keys (eg, the back key and the confirmation key) each time the virtual numeric keypad 20 is executed.
