Technical Field

The application relates to the technical field of terminal touch, in particular to a method and a terminal for displaying private information.

Background

In the scenes that a user uses various terminals or uses network services and the like, some private information related to the user is possibly not displayed on the used terminal or page all the time, so that others beside the user can not be snooped. Examples of private information are certificate numbers (e.g. identification numbers), passwords, personal financial product values (e.g. payroll displayed on a web page, balance in a wechat wallet, balance in a pay bank application, etc.). This information is generally sensitive to the user and is not intended to be revealed.

One method of displaying private information in the prior art is to set a button (or switch) next to the private information. When the button is not pressed, the private information is displayed as an asterisk (, a), or the like; when the button is pressed, the private information can display a true value; when the button is pressed again, the private information is restored to the asterisk, i.e., the true value is no longer displayed.

In the display mode in the prior art, the user needs to frequently switch the buttons in the process of displaying the real value of the private information and recovering to display the asterisk, so that the operation is complicated. Moreover, when the user presses the button, the actual value of the private information is displayed, and the user often performs other operations without pressing the button again in time. In this way, it is still possible to cause leakage of private information of the user.

Detailed Description

The embodiment of the application provides a method and a terminal for displaying private information.

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

An embodiment of the present application provides a method for displaying private information, as shown in fig. 1, including:

s110: a hidden symbol of the private information is displayed.

Similar to the prior art, private information of a user, such as some certificate numbers (e.g., identification numbers), passwords, personal financial product values (e.g., wages displayed on a web page, balance in a wechat wallet, balance in a pay bank application, etc.), may be displayed on a web page and in an application supporting a touch device. This information is generally sensitive to the user and is not intended to be revealed. The private information may appear as a hidden symbol such as an asterisk (a-x, etc.). The hidden symbol may also be blank, i.e. set to the same color as the background color or another color so that private information is not displayed, for example.

S120: and detecting pressure touch control within a preset range, and when the pressure touch control reaches or exceeds a first preset pressure threshold value, and the pressure touch control reaching or exceeding the first preset pressure threshold value is kept and reaches a preset duration, displaying the true value of the private information.

The pressure sensing screen technology has been widely adopted in the prior art. The pressure induction screen technology can expand the touch screen from traditional two-dimensional operation to three-dimensional operation, and different operations are realized by identifying the force different in size in the direction perpendicular to the touch screen, so that the touch screen can identify the pressing force of a user and provide different service options. The pressure sensing screen technology has better experience, makes up the limitation of the size of a touch screen, and has better tactile feedback and more real emotional interaction. The appearance of the pressure sensing screen technology enables users to have a brand new mode of interacting with mobile phones.

Pressure sensitive screen technologies such as Force Touch, 3D Touch, ClearForce, etc.

Force Touch and 3D Touch are based on the same technology. The operation experience of 3D Touch is better than that of Force Touch, and the method can be called as an upgrade version of Force Touch. Apple release with 3D Touch appearing on 9/10/2015 is carried on iPhone 6s, and has two new gestures, Peek (light press) and Pop (heavy press). Apple is called a new generation of multi-touch technology. In short, the Apple strengthens the Force Touch scheme on Apple Watch, and further strengthens the interaction formed by Touch control by using different Force induced by a pressure induction screen.

The ClearForce pressure-sensing touch solution is a new man-machine interaction mode which is provided for customers by a leading developer, Synaptics and the like of a man-machine interaction solution facing the market. For example, by applying different forces with a finger or stylus, adjusting scrolling speed and zoom scale, implementing continuously variable game control, and different text or photo editing modalities, device manufacturers may be enabled to implement smartphone differentiation. After giving a complete set of solutions by Synaptics, android phones also start to use the technology in a large area, for example, the technology is adopted in hua math (math) S which comes into the market 9/2015.

In addition to pressure-sensitive screen technology, there are also pressure Touch pads, such as apple-on-notebook integrated Force Touch pads. Compared with the common Touch control panel, the Force Touch control panel is internally integrated with a Force sensor. Compared with the conventional Touch pad, the Force Touch pad can not only identify the pressing position, but also sense the pressing Force.

Taking the example of a touch screen pressure detector, the touch screen pressure detector may detect not only the presence of pressure against the touch screen display, but also the amount of pressure applied to the touch screen display. By detecting pressure as a continuously variable input rather than simply as an on/off binary input, the touch screen pressure detector can distinguish between soft touch and hard touch, similar to the aforementioned Peek (light press), Pop (heavy press), in addition to detecting direction and speed of contact with the touch screen. The touch screen pressure detector can provide three-dimensional input by detecting where the screen pressure is applied (i.e., the x-dimension and the y-dimension) and the amount of pressure applied to that point (i.e., the z-dimension). Thus, the same pressure applied to different points on the surface of the touch screen (e.g., lower left or upper right corner) can produce different input signals, as well as the same pressure applied to the same point on the surface of the touch screen (e.g., hard or soft pressure on a point on the screen).

In general, the terminal device may detect a pressure touch within a preset range of the touch screen, for example, detect a pressure touch in an area where a hidden symbol is displayed. Of course, the pressure touch may be detected in a predetermined area other than the hidden symbol, for example, one or a string of predetermined symbols indicating pressing with force. The symbol prompting hard pressing may be located adjacent to the region where the hidden symbol is displayed.

The pressure touch may be generated by pressing with a finger of a user, or may be generated by a touch device, such as a stylus.

And when the pressure touch reaches or exceeds a first preset pressure threshold and the pressure touch reaching or exceeding the first preset pressure threshold reaches a preset duration, displaying the real value of the private information. The first predetermined pressure threshold may be set to a pressure threshold that generates Peek (light press) or may be set to a pressure threshold that generates Pop (heavy press). The pressure touch input of the user may be further differentiated by duration. In some embodiments, the touch screen pressure detector can detect the time of the pressure touch to generate different input signals. The duration of the generated pressure touch, such as the amount that remains at or above the first predetermined pressure threshold, may be further considered. The duration may be an input parameter in a fourth dimension (e.g., a pressure touch, such as a duration t that remains at or above a predetermined pressure threshold by an amount, as a dimension other than x, y, z, as described above).

The first preset pressure threshold is set to be Peek (light press) and can be selected to be 5-10 gf (gram force), and the first preset pressure threshold is set to be Pop (heavy press) and can be selected to be 15-20 gf. The preset time t may be set to 40ms to 60ms, preferably 50ms, so as to generate a sensitive touch feedback.

Furthermore, the pressure touch can be generated by pressing of a finger on the touch screen by a user or by pressing of a touch device on the touch screen by the user; the pressure touch control may be generated by pressing a finger on the touch pad by a user when the cursor is located within a preset range of the screen, or generated by pressing the touch pad by the user when the cursor is located within the preset range of the screen; but also by a user pressing a predetermined area on the touch pad with a finger or by a user pressing a predetermined area on the touch pad with a touch device.

In one case, the pressure touch within the preset range may be generated by pressing a finger on the touch screen by a user, or generated by pressing a touch device on the touch screen by the user, and the pressed area may be located in a partial area of the private information. When the pressure touch in such a range is detected, the pressure touch reaches or exceeds a first predetermined pressure threshold, and the pressure touch reaching or exceeding the first predetermined pressure threshold is maintained and reaches a preset duration, the actual value of the private information may be displayed in a screen area corresponding to the pressing area. For a larger area of the display of the private information, an area displaying the real value caused by the pressure touch may occupy a part of the display area of the private information. In this case, for example, a part of the private information is displayed as a real value due to the pressure touch, and the private information in other areas is still a hidden symbol. Correspondingly, as the user presses and moves on the touch screen through a finger, or the user presses and moves on the touch screen through the touch device, in the area to which the user presses and moves, if the pressure touch still reaches or exceeds the first predetermined pressure threshold, and the pressure touch reaching or exceeding the first predetermined pressure threshold is kept and reaches a preset time length, the hidden symbol can be switched and displayed as a real value in the private information display area.

S130: and when the pressure touch value is detected to disappear or fall below a second preset pressure threshold value, restoring and displaying the hidden symbol of the private information.

The user can view the real value of the displayed private information through the step S120.

After the user finishes viewing, the user can lift up the touch device such as a finger or a touch pen generating pressure touch.

The terminal device can detect pressure touch in a preset range of the touch screen, and when the pressure touch value disappears or falls below a second preset pressure threshold value, the hidden symbol of the private information is restored and displayed. When the first predetermined pressure threshold is set to Peek (tap), for example, the second predetermined pressure threshold may be set to 1 gf. The second predetermined pressure threshold may be set to 11gf, when the first predetermined pressure threshold is set to Pop (heavy pressure), for example.

In this way, when the user lifts a touch device such as a finger or a stylus generating pressure touch, the terminal device detects that the pressure touch value disappears or falls below a second predetermined pressure threshold, so that the private information can be immediately restored and displayed as a hidden symbol.

As mentioned above, in the case where the pressing area is located in a partial area of the private information, for a larger area of the private information display, the area where the real value is displayed due to the pressure touch may occupy a part of the private information display area. In this case, for example, when the pressure touch value disappears or falls below the second predetermined pressure threshold, a part of the private information is restored and displayed as a hidden symbol. Correspondingly, as the user presses and moves on the touch screen through a finger, or the user presses and moves on the touch screen through the touch device, in the area just passed by the movement, when the pressure touch value disappears or falls below a second predetermined pressure threshold value, the real value can be switched and displayed as a hidden symbol in the private information display area.

Through the embodiment, the private information can be displayed as the real value only when the user touches the touch screen with certain force and keeps a certain time, and the hidden symbol of the private information is restored and displayed when the pressure touch disappears or drops below the second preset pressure threshold, so that the private information can be rapidly and conveniently switched and displayed between the real value and the hidden symbol.

The present application further provides a terminal for displaying private information, as shown in fig. 2, including:

a display unit 21 for displaying a hidden symbol or a real value of private information;

the touch detection unit 22 is configured to detect a pressure touch within a preset range, and when the pressure touch reaches or exceeds a first preset pressure threshold, and the pressure touch reaching or exceeding the preset pressure threshold is maintained and reaches a preset duration, trigger the display unit to display a true value of the private information; and when the pressure touch is detected to disappear or fall below a second preset pressure threshold value, triggering the display unit to restore and display the hidden symbol of the private information.

Preferably, the touch detection unit detects a pressure touch in an area where the hidden symbol is displayed; or detecting pressure touch in a symbol area prompting to press with force, wherein the symbol area prompting to press with force is located in an adjacent area of the displayed and hidden symbol area.

Preferably, the pressure threshold value for generating the light press is selected to be 5-10 gram force.

Preferably, the preset time period t is set to 40ms to 60 ms.

Preferably, the preset time period t is set to 50 ms.

or the like, or, alternatively,

the pressure touch is generated by a user pressing a predetermined area on the touch pad with a finger or by a user pressing a predetermined area on the touch pad with a touch device.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.

The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.

The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions.

For convenience of description, the above devices are described as being divided into various units by function, and are described separately. Of course, the functionality of the units may be implemented in one or more software and/or hardware when implementing the present application.
