Description
The application relates to a patent application division application with the application number 201510967595.2 which is filed on the 21 th 12 th 2015 and named as an information image display method and device.
Technical Field
The present application relates to the field of information processing technologies, and in particular, to a method and an apparatus for displaying an information image.
Background
With the development of intelligent equipment technology, the devices such as a mobile phone and a watch of a user can support various short-distance information exchange modes, and accordingly, many application scenes such as payment, access control, business card exchange and the like are generated. In various short-distance information exchange modes, the information exchange by using images is widely applied, and the basic principle is as follows: the method comprises the steps of converting information to be transmitted into a form of an image (such as a two-dimensional bar code, a one-dimensional bar code or a variable bar code) through a specific coding mode, displaying the image on a screen of a transmitting end device when the information is required to be transmitted, acquiring the image by a receiving end device through a camera or a special scanning module, and then decoding the image to obtain original information.
The information exchange by using the image has the characteristics of simple realization and convenient use, but on the other hand, because the image can be easily obtained by any other device when the information image is displayed on the transmitting end device, the information transmitting mode has broadcasting property to a certain extent. However, in many practical application scenarios, various private information, such as payment account numbers, passwords, etc., may be carried in the information image, which may have serious consequences if the malicious user records the image by means of candid photographing, etc. Therefore, how to improve the security of image information exchange is an important research direction at present.

Determining an information image to be displayed according to the information image display instruction;
detecting the pressing state of a predefined key;
And in the state that the predefined key is detected to be pressed, displaying the information image on a screen of the user equipment, otherwise, not displaying the information image.
According to the 2 nd aspect of the present application, there is provided an information image display apparatus, applied to a user equipment, comprising:
the display instruction receiving module is used for receiving the information image display instruction;

And the display control module is used for displaying the information image on a screen of the user equipment in a state that the predefined key is detected to be pressed, and otherwise, not displaying the information image.
According to the technical scheme provided by the application, the user-defined key is used as one of triggering conditions for displaying the information image, when a user hopes to display the information image to a specific receiver by using the mobile device and execute corresponding display operation, the information image is not immediately displayed on the screen of the user device, and only when the user presses the correct user-defined key, the information image is displayed on the screen of the user device. In practical application, when the user approaches the user equipment to the image information receiving device, the user can press the custom key, at this time, the information image will be displayed on the screen of the user equipment, and after the user removes the finger from the key, the information image displayed on the screen of the user equipment will disappear immediately.
According to the technical scheme provided by the application, the possibility of maliciously acquiring the image is reduced by shortening the effective display time of the information image, and even in the information image display period, the behavior of maliciously acquiring the image is objectively difficult to implement due to the practical environment limitations such as 'approaching a receiving device', 'holding by a user', and the like. On the other hand, by adding the custom key verification process, the legal identity of the current operation user can be effectively ensured, so that the use safety of the information image is further improved.

Detailed Description
According to the existing information image using method, after a user triggers a display function on the device, the information image is always displayed on the screen of the device until the user manually cancels the display or the device automatically enters a standby state, and in the period of time, the risk that the information image is maliciously acquired is high. Taking a mobile phone two-dimension code payment scene as an example, many users are used to display the payment two-dimension code on the mobile phone in advance when waiting for payment in a queue, or do not execute the cancel display operation immediately after the payment is finished, and even unconscious user behaviors that the mobile phone displaying the payment two-dimension code is placed on one side … … possibly because of being busy with doing other things (such as packaging after shopping) can create conditions for malicious users.
Aiming at the problems, the scheme provided by the application is that the user equipment is controlled to display the information image by utilizing the custom key, and when the custom key is pressed by a user in practical application, the information image can be displayed on a screen of the user equipment, otherwise, when the user leaves a finger from the custom key, the information image can disappear immediately, and the use safety of the information image is improved by the mode.
In order that those skilled in the art will better understand the technical solutions of the present application, the following detailed description of the technical solutions of the embodiments of the present application will be given with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which are derived by a person skilled in the art based on the embodiments of the application, shall fall within the scope of protection of the application.
The information image display scheme provided by the application can use the physical key or the touch virtual key on the user equipment as the custom key, and can also use the virtual key in the operating system interface or the specific application interface as the custom key for the user equipment with the touch screen. Of course, in order to realize the display of the information image, the user equipment also needs to have a basic display function, and the specific user equipment can be a composite device such as a mobile phone, a tablet computer, a smart watch, or a single-function device such as an electronic business card and an electronic tag. In addition, the specific form of the information image can be two-dimensional codes, one-dimensional bar codes or variable bar codes, etc., and the application scene can be payment, entrance guard, business card exchange, etc., which do not affect the realization of the scheme of the application.
Fig. 1 is a flowchart of an information image display method according to the present application, which may include the following steps:
S101, receiving an information image display instruction;
s102, determining an information image to be displayed according to the information image display instruction;
s103, detecting the pressing state of the predefined key;
S104, in the state that the predefined key is detected to be pressed, displaying the information image on a screen of the user equipment,
S105, in a state where the depression of the predefined key cannot be detected, the information image is not displayed.
The following describes the above scheme taking an application scenario of using a mobile phone two-dimensional code (also called a two-dimensional bar code) to make a quick payment as an example.
The mobile phone user needs to designate one or more keys in advance as a trigger password when the two-dimension code is displayed, wherein the keys can be physical keys or touch virtual keys on the mobile phone, or can be virtual keys in a touch screen operating system interface or a specific application interface, and the mobile phone side records and stores the key information.
According to S101, when the user wishes to pay using the two-dimensional code, a corresponding trigger operation is performed on the mobile phone, for example, the functions such as "payment code", "pay on the surface" are selected in the specific application, so as to send an information image display instruction, which in this embodiment is equivalent to the payment operation instruction, to the mobile phone. Of course, the user may also implement the display triggering operation through gestures, voice control, and other manners, which are not limited by the present application.
According to S102, after receiving the information image display instruction, the mobile phone determines a two-dimensional code image for payment. Here, the static two-dimensional code image generated in advance may be acquired, or the two-dimensional code image may be generated by means of instantaneous encoding.
The method and the device have the advantages that after the two-dimensional code image is determined, the two-dimensional code image is not immediately displayed on a mobile phone screen, but the mobile phone is enabled to enter a trigger display state, and in the state, whether other trigger conditions are met is further judged, and whether the two-dimensional code image is displayed is controlled according to the trigger condition.
The application uses the self-defined key as another triggering condition for displaying the two-dimensional code image. According to S103 to S105, in the image trigger display state, the pressed state of the custom key is continuously detected, and if it can be detected that the custom key is in the pressed state (if a plurality of keys are specified in advance, it may be required that the plurality of keys are pressed at the same time or any key is pressed), the determined two-dimensional code image is displayed on the mobile phone screen, otherwise, if it cannot be detected that the custom key is pressed, the two-dimensional code image is not displayed.
According to the scheme, the display time of the two-dimensional code image can be skillfully controlled by utilizing the user-defined keys. In actual application, when the mobile phone is in an image triggering display state, once the user is detected to press the user-defined key, the display of the two-dimensional code image can be triggered, otherwise, when the user-defined key is not detected to be pressed, the two-dimensional code image is not displayed on the mobile phone screen. By the method, on one hand, the effective display duration of the two-dimensional code image can be shortened, the possibility of malicious acquisition of the image is reduced, and even in the information image display period, a user can hold the device all the time and can control the user to press the finger on the custom key only when the code is scanned, at the moment, the code scanning device is close to and blocked in front of a mobile phone screen, and under the condition, the method is difficult to implement whether the camera or the manual candid photograph is utilized.
In addition, the scheme of the application uses the custom key as a user authentication mechanism, and in this way, the current operator of the user equipment can be effectively confirmed to be a legal user, and the loss caused by the operation of the user equipment by an illegal user is avoided.
Fig. 2 is a schematic diagram of a specific implementation scenario in which the scheme of the present application is applied to merchant payment, and a user designates a "volume reduction" key of a mobile phone as a custom key in advance. When the user selects the "pay on face" function in the payment device application, the two-dimensional code image is not immediately displayed on the mobile phone screen. When the code scanning payment is needed, after the user's finger presses the ' volume reduction ' key, the two-dimensional code image is triggered to be displayed on the mobile phone screen. After the code scanning interaction is completed, the user finger leaves the 'volume reduction' key, and the two-dimensional code image displayed on the mobile phone screen disappears.
It will be understood that "not displaying an information image" in the present embodiment refers to not displaying an image carrying information to be actually transmitted, so that the actual display mode is not limited to displaying a blank area. For example, in one embodiment of the present application, a dummy image may be displayed on the screen of the user device during the "no information image is displayed". As shown in fig. 3, the pseudo image may take a similar pattern to the real image, but does not carry effective information to be transmitted, such as account numbers and passwords in a payment scene, names and contact ways in a business card exchange scene, and the like, so that even if the pseudo image is maliciously acquired, no actual loss is caused. According to the actual requirement, other functional information can be further added into the pseudo image, for example, the method can be set as follows: when the pseudo-image is scanned, a certain alarm mechanism is triggered to remind a user that someone is using the pseudo-image, and the security of personal information is noted.
In addition, when the information image is not displayed, some prompt information may be displayed to prompt the user to input the custom key information, for example, a word such as "please press the custom key" may be displayed. Of course, the user may be presented by means of sound, vibration, or the like, and the present application is not limited to a specific output mode of the presented information.
For the case of using virtual keys of the user interface as custom keys, a virtual keyboard for inputting custom key information may also be displayed on a screen without displaying an information image, and the keyboard corresponding to the input style may be characters, graphics, color blocks, or the like. In another embodiment, for the virtual key implemented on the user interface, when the user needs to press the custom key, the virtual key may be in an invisible state, as shown in fig. 4, where the custom virtual key specified by the user is actually a certain area of the touch screen, in the key specifying stage, the area corresponding to the key may be displayed to the user, and in the actual using stage, that is, when the custom key pressing state is detected, the actual shape and outline of the key may not be displayed on the screen of the user device, and for the legal user of the device, the correct position may be completely pressed according to the prompt to trigger the display of the information image, so as to further operate the concealment in this manner.
In view of the fact that the user himself may be hard to see during the actual display of the information image, a certain kind of prompt information may also be output after the display of the information image to inform the user that the image has been displayed correctly. In combination with the actual situation of the user equipment, the optional prompting modes include sound, vibration, flash lamp indication and the like, and the prompting is realized in a mode of triggering the equipment to vibrate in consideration of factors such as environmental noise interference, confidentiality and the like, so that the specific output mode of the prompting information is not limited.
In a specific embodiment of the present application, it may be further configured to stop detecting the pressed state of the custom key when the duration of the pressed state of the custom key cannot be detected exceeds a preset certain threshold (for example, 20 seconds, 30 seconds, etc.), that is, exit from the image triggering display state. Thereby further improving security and reducing power consumption of the user equipment.
Corresponding to the above method embodiment, the present application further provides an information image display device, as shown in fig. 5, which may include:
a display instruction receiving module 110 for receiving an information image display instruction;

The second prompting module 160 is configured to output a second prompting message after the information image is displayed, so as to prompt the user that the information image is displayed correctly. For example, the second prompt information is output in a mode of triggering the vibration of the user equipment.
It should be understood that the first prompting module 150 and the second prompting module 160 may be configured in the device at the same time as shown in fig. 6, or may be configured in the device separately and separately, so the structure shown in fig. 6 should not be construed as limiting the scheme of the present application.
