The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
The present application will be described in detail with reference to specific examples.
In one embodiment, as shown in fig. 1, a two-dimensional code display method is specifically proposed, which can be implemented by relying on a computer program and can run on a two-dimensional code display device based on von neumann architecture. The computer program may be integrated into the application or may run as a separate tool-like application. The two-dimensional code display device may be an electronic device, including but not limited to: wearable devices, handheld devices, personal computers, tablet computers, in-vehicle devices, smart phones, computing devices or other processing devices connected to a wireless modem, and the like.
Specifically, the two-dimensional code display method comprises the following steps:
s101, receiving a starting instruction aiming at a data transfer two-dimensional code, and displaying the data transfer two-dimensional code by adopting a first definition, wherein the first definition is smaller than a definition threshold value;
the two-dimensional code is a pattern which is distributed on a plane (in a two-dimensional direction) according to a certain rule by using a certain specific geometric figure, is black and white and is alternated and records data symbol information; the concept of "0" and "1" bit stream forming the internal logic basis of computer is used ingeniously in coding, several geometric forms correspondent to binary system are used to represent literal numerical information, and can be automatically read by means of image input equipment or photoelectric scanning equipment so as to implement automatic information processing.
Commonly used code systems are: QR (quick response) Code, Data Matrix, MaxiCode, Aztec, Vericode, PDF417, Ultracode, Code 49, Code 16K, and the like. The most common two-dimensional Code is QR Code, which is an encoding mode that is super-popular on mobile devices in recent years, and compared with the traditional Bar Code barcode, the barcode can store more information and represent more data types.
The two-dimensional code can be used in different fields, such as website skipping, advertisement pushing, member management, account login, data transfer and the like. In the embodiment of the application, the application is applied to the field of data transfer, and the mentioned two-dimensional code is a data transfer two-dimensional code and is generally arranged in a data transfer application or a data transfer applet or a data transfer website.
Taking the data transfer two-dimensional code as an example, the data transfer two-dimensional code is set in the data transfer application, and after the user opens the data transfer application, the user clicks the data transfer function therein, and then the data transfer two-dimensional code is displayed in the display interface.
It should be noted that, before presentation, a data transfer two-dimensional code region in the data transfer page is identified, and the data transfer two-dimensional code region is subjected to fuzzy processing, so as to reduce the definition of the data transfer two-dimensional code to reach a fuzzy degree. The definition threshold value can be understood as the definition degree which cannot be identified by the cash register device, and after fuzzy processing, the user information contained in the two-dimensional code cannot be read when the cash register terminal scans. And the data transfer two-dimensional code can be subjected to fuzzy processing by adopting a common image fuzzy algorithm. Of course, the simplest implementation may be to adjust only the sharpness of the two-dimensional code region.
S102, when the safety of the current data transfer environment is confirmed, adjusting the current definition of the data transfer two-dimensional code to a second definition, wherein the second definition is greater than or equal to the definition threshold;
the data transfer environment is an environment state around when the data transfer is performed under the current environment and the data transfer two-dimensional code is displayed.
And identifying the data transfer environment and judging whether the environment is safe or not so as to avoid property loss caused by information leakage. One feasible identification method is to start the camera and identify the payment environment by using the front camera. The camera can be a front camera, can also be a rear camera, and can also be a front camera and a rear camera. Of course, since the data transfer two-dimensional code is displayed on the display interface, the stealing of the two-dimensional code is mostly located above the display interface, for example, if a nearby person aims at the data transfer two-dimensional code to take a picture, or the data transfer two-dimensional code is directly scanned by a mobile phone, the stealing occurs, and therefore, it is preferable to turn on the front camera.
Specifically, the camera is used for collecting surrounding environment information, whether the condition that the unknown equipment shoots or scans the two-dimensional code exists or not is identified, if not, the safety of the current data transfer environment is confirmed, and otherwise, the safety is not ensured. When the security is confirmed, it indicates that the data transfer operation can be performed, and therefore, the definition of the fuzzy data transfer two-dimensional code needs to be adjusted, so that the cash register terminal can conveniently recognize the fuzzy data transfer two-dimensional code.
The process of two-dimensional code sharpening is the reverse process of the fuzzy processing. The definition of the fuzzy two-dimensional code can be adjusted only, and the image definition algorithm can also be adopted for realizing the definition. For the image processing clearness algorithm, the realization principle is as follows: the general image is composed of three primary colors of color light, red, green and blue, and theoretically, only one color information is complete, the general image can be used for assisting in repairing other color light, so that the image can be cleared as long as the color light distribution condition at the time can be calculated.
The definition threshold is the lowest definition recognizable by the cash register terminal, and the second definition is any value larger than the threshold and can be preset.
S103, displaying the data transfer two-dimensional code by adopting the second definition.
After the definition adjustment of the data transfer two-dimensional code is completed, the data transfer two-dimensional code can be clearly displayed in a two-dimensional code area of a display interface.
Furthermore, the cash register terminal can scan and identify the two-dimensional code, and for the terminal, the cash register terminal receives a data transfer instruction and performs data transfer.
Optionally, after the data transfer is confirmed to be successful, the data transfer two-dimensional code is closed or periodically refreshed, so as to further confirm information security.
In the embodiment of the application, an opening instruction for the data transfer two-dimensional code is received, the data transfer two-dimensional code is displayed by adopting the first definition smaller than the definition threshold, and when the safety of the current data transfer environment is confirmed, the current definition of the data transfer two-dimensional code is adjusted to be the second definition larger than or equal to the definition threshold, and then the second definition is displayed by adopting the data transfer two-dimensional code. Through discerning data transfer environment security to the definition show data transfer two-dimensional code of difference has reduced the risk of being discerned by other equipment, and then has improved the security of data transfer.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating another embodiment of a two-dimensional code display method according to the present application. Specifically, the method comprises the following steps:
s201, receiving a starting instruction aiming at a data transfer two-dimensional code, starting a data transfer page, and identifying a data transfer two-dimensional code area in the data transfer page;
the two-dimensional code is a pattern which is distributed on a plane (in a two-dimensional direction) according to a certain rule by using a certain specific geometric figure, is black and white and is alternated and records data symbol information; the concept of "0" and "1" bit stream forming the internal logic basis of computer is used ingeniously in coding, several geometric forms correspondent to binary system are used to represent literal numerical information, and can be automatically read by means of image input equipment or photoelectric scanning equipment so as to implement automatic information processing.
In the embodiment of the application, the two-dimensional code is applied to the field of data transfer, is a data transfer two-dimensional code, and is generally arranged in a data transfer application, a data transfer applet or a data transfer website.
One possible implementation manner is that, when a user opens a data transfer application and clicks a data transfer function therein, a data transfer page is opened, as shown in fig. 3, the data transfer page includes a plurality of display areas, for example, a is an option function area, B is a data transfer two-dimensional code display area, and C is a payment method selection area. Of course, after the B area is further clicked, only the data transfer two-dimensional code is displayed on the interface, as shown in fig. 4.
Furthermore, the screenshot of the page is captured, then the gray level processing is carried out, then the binarization processing is carried out on the image, and then the morphological opening operation is carried out on the y direction and the x direction. And then marking the connected area, finding three characteristic areas of the two-dimensional code for positioning, and finally determining the coverage area of the two-dimensional code through the positioning pattern. The opening operation refers to an operation of first corroding and then expanding. As shown in fig. 4, the area D is the coverage area of the identified data transfer two-dimensional code.
Optionally, the data transfer two-dimensional code displayed with the first definition is refreshed according to a preset period, and even if the two-dimensional code is fuzzy and difficult to recognize, the recognition of the two-dimensional code can be more effectively avoided through periodic refreshing. S202, carrying out fuzzy processing on the data transfer two-dimensional code area, and adjusting the current definition of the data transfer two-dimensional code to be a first definition, wherein the first definition is smaller than a definition threshold value;
the definition threshold is the lowest definition recognizable by the cash register terminal, and the first definition is any value smaller than the threshold and can be preset.
The identified two-dimensional code region is subjected to blurring processing, so that a blurred two-dimensional code can be obtained, as shown in fig. 5. Of course, if the display page further includes other regions, the blurring process may be performed on the other regions synchronously, and the display definition of the other regions may be maintained.
The image Gaussian blur technology can be adopted for blur processing, and the method comprises the following three steps: RenderScript, fastBlur, and optimization of RenderScript and fastBlur.
The render script is a high-performance operation intensive operation framework on Android, is mainly used for data parallel computation, and can rapidly process Gaussian image blur without frame loss particularly for image processing, photographic analysis and computer vision. The fastBlur is originally developed by Java, Gaussian fuzzy calculation is carried out on each pixel point, and finally the Bitmap is synthesized, so that a cubic package is not required to be introduced, the size of APK is not increased, and the problem of no compatible version is solved. RenderScript and fastBlur are optimized by first reducing bitmap to lose some pixel points, then fuzzifying, and then amplifying to the original size. Because the image is reduced and then is subjected to fuzzy processing, the pixel points and the radius which need to be processed are reduced, and the fuzzy processing speed is accelerated.
S203, displaying the data transfer two-dimensional code by adopting the first definition;
namely, the data transfer page containing the fuzzy two-dimensional code is directly shown.
S204, starting a camera to acquire a data transfer environment currently scanned by the camera;
it can be understood that, because the data transfer two-dimensional code is presented on the display interface, the stealing of the two-dimensional code is mostly located above the display interface, for example, if a nearby person aims at the data transfer two-dimensional code to take a picture, or directly scans the data transfer two-dimensional code through a mobile phone, the stealing occurs, and therefore, the camera is a front camera. Further, in order to cover a large scanning range, the camera is a rotatable camera.
After the camera is started, the video information around the camera is collected.
S205, identifying the data transfer environment, and determining whether the data transfer environment is safe;
and sequentially extracting features of each frame of image in the video information, and comparing the extracted features with the pre-stored unsafe features so as to find out whether matched features are consistent.
S206, when the safety of the data transfer environment is confirmed, adjusting the current definition of the data transfer two-dimensional code to a second definition, wherein the second definition is greater than or equal to the definition threshold;
when the matched and consistent features are not found, the safety of the current data transfer environment is confirmed, which indicates that the data transfer operation can be continuously completed, and in order for the cash register to successfully identify the data transfer two-dimensional code, the fuzzy two-dimensional code needs to be adjusted into a clear two-dimensional code. The second definition is any value greater than or equal to a definition threshold.
It should be noted that the adjustment of the definition of the two-dimensional code can be realized by using a commonly used algorithm for sharpening a blurred image, which is not specifically limited herein.
S207, when the current data transfer environment danger is confirmed, displaying environment danger prompt information;
and when the matched and consistent characteristics are found, confirming that the risk exists in the current data transfer environment, and displaying prompt information to inform a user of the existing risk behavior. The mode of displaying the prompt information can comprise outputting a prompt box containing prompt text, playing audio and video containing prompt contents, or flashing an indicator light and the like.
For example, as shown in fig. 6, after a camera of the terminal 1 is turned on, video information around the terminal is collected, if it is shot that the terminal 2 scans against the terminal 1, it is determined that the current data transfer environment is unsafe, a prompt box pops up on a display interface of the terminal 1, and as shown in fig. 7, the user is informed of "there is a risk in the current payment environment, is payment continued? ". The prompt box can be displayed in any area on the interface, and is preferably displayed by covering the two-dimensional code in order to protect the property safety of a user.
S208, receiving a denial instruction aiming at the environmental danger prompt message, and executing the step of adjusting the current definition of the data transfer two-dimensional code to a second definition;
it can be understood that when the user confirms to continue payment, the terminal receives a denial instruction for the environmental hazard prompt information, closes the prompt box, and adjusts the fuzzy two-dimensional code into the clear two-dimensional code.
S209, receiving a confirmation instruction aiming at the environmental danger prompt information, and closing the data transfer two-dimensional code;
when the user does not continue to pay, the terminal receives a confirmation instruction aiming at the environmental danger prompt information, then the prompt box is closed, and the fuzzy two-dimensional code is also closed, so that other terminal equipment can be completely prevented from identifying the related account information of the two-dimensional code.
S210, displaying the data transfer two-dimensional code by adopting the second definition;
after the user confirms that payment is continued or the current data transfer environment is recognized to be safe, the clear two-dimensional code is displayed on the recognized two-dimensional code area, as shown in fig. 4.
S211, receiving a data transfer instruction aiming at the data transfer two-dimensional code displayed by the second definition before refreshing, and transferring data;
s212, refreshing the data transfer two-dimensional code according to a preset period;
it can be understood that after the clear data transfer two-dimensional code is displayed, the risk of being shot or scanned by other users still exists, the two-dimensional code is refreshed according to a certain time interval, the two-dimensional code has a certain validity period, if the two-dimensional code is refreshed after one minute after the two-dimensional code is generated, the previous two-dimensional code is invalid, and therefore, the data transfer can only be completed by the currently displayed two-dimensional code.
S213, receiving a data transfer instruction aiming at the refreshed data transfer two-dimensional code displayed by the second definition, and transferring data;
the cashier terminal confirms after recognizing the two-dimensional code, and at the moment, the terminal needs a user to input a data transfer confirmation instruction so as to complete the final data transfer process.
And S214, after the data transfer is confirmed to be successful, closing the data transfer two-dimensional code.
After the data transfer is detected to be successful, in order to further reduce the risk of shooting or scanning by other equipment, the clear two-dimensional code is closed, and the camera is closed.
In the embodiment of the application, the data transfer environment is identified in safety, the data transfer two-dimensional codes are displayed in different definitions, risks identified by other equipment are reduced, and the safety of data transfer is improved. When the data transfer environment has risks, the user is prompted, corresponding operation is executed based on the requirements of the user, and user experience is improved. In addition, after the clear two-dimensional code is displayed, the two-dimensional code is periodically refreshed, so that the shot two-dimensional code is invalid, and the safety of data transfer is further improved.
