Detailed Description
In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in other sequences than those illustrated or described herein. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a flowchart illustrating an information processing method according to an exemplary embodiment, where the information processing method is used in a client device as illustrated in fig. 1, and includes the steps of:
in step S11, the target information is converted into N-bit binary bit data, where N is an integer greater than 1.
The target information may be any information that needs to be steganographically displayed in the screenshot, such as a device identifier, a serial number, and the like. Before information processing, the required target information may be acquired, specifically, the target information may be acquired under the trigger of some event, for example, when a specific operation of a user is received, the Did information of the device is read.
In order to steganographically display the target information in the pixel points of the screenshot, the target information may be first subjected to data conversion, and converted into a number of binary bit data, that is, a sequence of numbers 0 and 1. For example, the target information is "20a10D", it may be converted into binary bit data "001000001010000100001101".
In step S12, a plurality of pixel point positions in the to-be-processed screenshot are drawn according to the N-bit binary bit data to generate a target screenshot, where the drawing content of each pixel point position corresponds to L-bit binary bit data in the N-bit binary bit data, an interval exists between any two pixel point positions in the plurality of pixel point positions, and L is an integer less than N.
The screenshot to be processed may be a screenshot in which N-bit binary bit data corresponding to the target information is to be written into some of the pixel points, and may be a screenshot obtained by performing screenshot on the client device or a previously acquired screenshot.
In this step, the N-bit binary bit data may be steganographically written at different pixel point positions in the to-be-processed screenshot, specifically, a plurality of pixel point positions distributed at intervals may be determined from the to-be-processed screenshot, that is, at least two pixel point positions directly have interval pixel points, the pixel point positions may be distributed at equal intervals or at unequal intervals, each pixel point position may be used to write L-bit binary bit data in the N-bit binary bit data, and in order to ensure the continuity of the N-bit binary bit data, L bits may be sequentially extracted from the N-bit binary bit data from front to back, and the L bits are sequentially written into different pixel point positions in the pixel point positions. And each pixel point position can be subjected to color drawing according to corresponding L-bit binary bit data, for example, if the binary bit data is 1, the corresponding pixel point is drawn into black, and if the binary bit data is 0, the corresponding pixel point is drawn into white or unchanged.
In this way, a target screenshot can be generated by drawing the positions of the plurality of pixel points of the screenshot to be processed in the above manner, and the N-bit binary bit data is written into the plurality of pixel points of the target screenshot.
Optionally, the target pixel point position includes L pixel points, L binary bit data corresponding to the target pixel point position respectively correspond to the L pixel points, and the pixel point corresponding to the bit data of the first value is drawn as a first color when the L binary bit data includes the bit data of the first value;
wherein the target pixel point location is any one of the plurality of pixel point locations.
In this embodiment, each pixel point position may include L pixel points, each pixel point is configured to write 1 bit in corresponding L binary bit data, and when a certain bit data in the L binary bit data is a first value, the corresponding pixel point may be drawn into a first color, where the first value may be 1 or 0, the first color may be black, white, or another color, and when a certain bit data in the L binary bit data is not the first value, the corresponding pixel point may be drawn into another color other than the first color, or the pixel point may not be drawn into a color. Taking the drawing of the 4-bit binary bit data "1101" as an example, 4 pixel points in the corresponding pixel point positions can be respectively drawn as "black, white and black", it should be noted that, in order to reduce the drawing workload, the 4-bit binary bit data "1101" can be inverted to obtain "0010", then the 4 pixel points in the corresponding pixel point positions are respectively drawn as "white, white and black", and the data can be restored only by inverting the extracted binary bit data again when the server client parses the data.
In this way, by performing color rendering on each pixel point position in the plurality of pixel point positions according to the value of the corresponding L-bit binary bit data, the target information can be more covertly written in the target screenshot, and the visual impact on the target screenshot is less.
Optionally, M pixel points are spaced between any two pixel point positions in the plurality of pixel point positions, where M is an integer greater than 1.
That is, the pixel positions may be distributed at equal intervals, and M pixel positions are spaced between every two pixel positions, for example, M is 10 or 15, so that L-bit binary bit data may be written into every M pixel positions in the screenshot to be processed, so that the N-bit binary bit data may be written into the screenshot to be processed more regularly. In order to ensure a larger fault-tolerant rate and avoid errors or information loss when the target screenshot is decompressed after being compressed, the positions of the pixel points can be spaced at larger intervals, that is, the M can take a larger value.
Optionally, the pixel point positions are located in the first row of pixels or the last row of pixels of the screenshot to be processed.
In order to avoid that the visual effect of the generated target screenshot is influenced by drawing according to the N-bit binary bit data in the middle of the screenshot to be processed, the screenshot may be drawn in the first line of pixels or the last line of pixels of the screenshot to be processed, that is, a plurality of pixel point positions are selected from the first line of pixels or the last line of pixels of the screenshot to be processed, so as to write the N-bit binary bit data into the screenshot. Specifically, the last line of pixels of the screenshot to be processed, that is, the bottom of the screenshot to be processed, may be drawn first, and when the N-bit binary bit data is not written, the first line of pixels of the screenshot to be processed, that is, the top of the screenshot to be processed, may be drawn continuously.
For example, as shown in fig. 2, device Did information may be written in a plurality of pixel point positions at the top or bottom of the screenshot 20 obtained by the screenshot, and a plurality of pixel points are spaced among the plurality of pixel point positions. One bit of Did information is written in each pixel position, each pixel at each pixel position draws a color, and one bit of Did information is written in every 4 colors.
In this way, only the colors of some pixel points at the bottom or top of the screenshot to be processed are changed, and it can be ensured that the visual impact on the target screenshot is small.
In step S13, the target screenshot is sent to the server device.
After the target screenshot is generated and obtained, the target screenshot can be sent to the server side device, so that the server side device extracts and analyzes the target information from the target screenshot, and safe transmission of the target information is achieved.
Optionally, the target information includes device identification Did information of the client device, and before step S11, the method further includes:
when screen capturing operation of a user is received, screen capturing is carried out on the client equipment to obtain a screenshot to be processed, and Did information of the client equipment is obtained;
the step S13 includes:
and sending the target screenshot and a user log to a server device, wherein the user log is an operation behavior log of a user on the client device.
In this embodiment, the target information may be device identification information, that is, did information of the client device, and may be that, when a screen capture operation is received, the screen capture is performed on the client device to obtain a screenshot to be processed, and when the screen capture is performed, the Did information of the client device is read, so that the Did information of the client device is steganographically written in the screenshot to be processed.
After the target screenshot is generated, the target screenshot and a user log can be sent to a server device, wherein the user log is an operation behavior log of a user on the client device, the user log can be used for a technician to locate a problem encountered when the user operates an application program of the client device based on the user log, and the target screenshot can be used for the technician to locate a device for feeding back the problem.
The method can be applied to the scene of user feedback problems, the flow of the user feedback problems can be optimized through the method, the user can trigger the report of the user log only by executing the screen capture operation, the device Did information is written into the screen capture obtained by the screen capture operation, and technicians can position the problem of the user feedback according to the screen capture and the user log received by the server device.
Optionally, the Did information of the client device is composed of numbers and letters;
the step S11 includes:
and converting each bit value in the Did information of the client device into L-bit binary bit data respectively.
The Did information of the client device generally consists of numbers and letters, so that when the Did information of the client device is subjected to data conversion, each bit value in the Did information of the client device can be converted respectively, and each bit value can be converted into L-bit binary bit data, so that N-bit binary bit data in total can be obtained.
For example, if the Did information of the client device is "20a10D", each bit value thereof may be converted into 4-bit binary bit data, i.e., 0010, 0000, 1010, 0001, 0000, and 1101, so that a 24-bit binary bit data sequence "001000001010000100001101" may be obtained.
When a plurality of pixel point positions in the screenshot to be processed are drawn according to the N-bit binary bit data, the binary bit data corresponding to a bit value in the Did information of the client device may also be respectively drawn at each pixel point position, for example, "0010" is drawn at a first pixel point position, "0000" is drawn at a second pixel point position, "1010" is drawn at a third pixel point position, and so on.
In this way, when the Did information of the client device is extracted and analyzed from the target screenshot, a bit value in the Did information of the client device can be extracted from each pixel point, and thus complete Did information of the client device is obtained.
The technical scheme can be applied to scenes such as hidden information and user feedback problems. The information to be hidden is drawn in different pixel points of the screenshot, so that the effect of hiding the information can be achieved, the information is lighter, and the compression resistance is strong. When the method is applied to a scene of a user feedback problem, the Did information of the equipment can be acquired and steganographically captured in a screenshot obtained by the screenshot when the user executes the screenshot operation, and the user log reporting can be triggered during the screenshot operation, so that technical personnel can position the problem according to the screenshot and the user log, the user feedback process can be greatly simplified, the user can be disturbed as little as possible, the problem can be positioned as fast as possible, and the user experience is improved.
In the related art, when device Did information is hidden, the least significant bit LSB method is usually adopted, and the principle is to hide the information in the least significant bits of the original material information. Taking a picture as an example, the picture is essentially a set of color pixel points, each pixel point can be composed of three primary colors of RGB, red, green and blue, namely, each pixel point has 24 bits, namely, 8 bits of red, 8 bits of green and 8 bits of blue, each three primary color has 256 colors, and the LSB principle is that only the value (0 or 1) of the last bit is modified, namely, the color of a certain pixel is slightly adjusted, and the human eye can hardly perceive the change. That is, in this method, the information to be hidden is written into the last bit of the pixel. However, after the picture obtained in this way is compressed, the stored bit information is easily lost, and the larger the compression ratio is, the more information is lost. In the scheme, target information needing to be hidden is drawn at the positions of a plurality of pixel points in the screenshot at intervals, so that the generated target screenshot can be ensured to have stronger compression resistance, the fault tolerance rate can be improved by increasing the drawing interval, and the target information is prevented from being lost when the picture is compressed.
The information processing method provided by the embodiment of the disclosure converts target information into N-bit binary bit data, wherein N is an integer greater than 1; drawing a plurality of pixel point positions in the screenshot to be processed according to the N-bit binary bit data to generate a target screenshot, wherein the drawing content of each pixel point position corresponds to L-bit binary bit data in the N-bit binary bit data, an interval exists between any two pixel point positions in the plurality of pixel point positions, and L is an integer smaller than N; and sending the target screenshot to server-side equipment. Therefore, the target information needing to be hidden is drawn at the positions of a plurality of pixel points in the screenshot at intervals, so that the generated target screenshot can be ensured to have strong compression resistance.
Fig. 3 is a flowchart illustrating an information processing method according to an exemplary embodiment, where the information processing method is used in a server device, as shown in fig. 3, and includes the following steps:
in step S31, a target screenshot sent by the client device is received.
The target screenshot may be obtained by the client device drawing a plurality of pixel point positions in the screenshot to be processed according to binary bit data corresponding to the target information, and a specific drawing manner may be as described in the embodiment shown in fig. 1.
In this step, the server device may receive the target screenshot sent by the client device.
In step S32, N-bit binary bit data is extracted from a plurality of pixel point positions in the target screenshot, where each pixel point position corresponds to L-bit binary bit data, an interval exists between any two pixel point positions in the plurality of pixel point positions, N is an integer greater than 1, and L is an integer less than N.
After receiving the target screenshot, the N-bit binary bit data may be extracted from a plurality of pixel point positions in the target screenshot according to a writing manner of the N-bit binary bit data in the target screenshot, where the writing manner may be predefined by the client device and the server device, and specifically, the pixel point positions in the target screenshot may be determined first, and then, according to a pixel point color of each pixel point position, the corresponding L-bit binary bit data may be determined, so that the N-bit binary bit data may be obtained in total. For example, if the color of a certain pixel is black, the binary bit data corresponding to the certain pixel can be read as 1, and if the color of a certain pixel is white, the binary bit data corresponding to the certain pixel can be read as 0.
In step S33, the N-bit binary bit data is analyzed to obtain target information.
After obtaining the N-bit binary bit data, the N-bit binary bit data may be converted to obtain corresponding target information, for example, if the N-bit binary bit data is "001000001010000100001101", the corresponding target information may be analyzed to be "20a10D" by hexadecimal conversion.
Optionally, the pixel points are located in the first line of pixels or the last line of pixels of the target screenshot.
In order to avoid that the visual effect of the generated target screenshot is influenced by drawing according to the N-bit binary bit data in the middle of the screenshot to be processed, when the N-bit binary bit data is written into the screenshot to be processed, the N-bit binary bit data can be drawn in the first line of pixels or the last line of pixels of the screenshot to be processed, so that the positions of a plurality of pixel points written with the N-bit binary bit data in the obtained target screenshot are also positioned in the first line of pixels or the last line of pixels of the target screenshot, namely the positions of the plurality of pixel points are positioned at the top or the bottom of the target screenshot.
Optionally, the step S31 includes:
receiving a target screenshot and a user log sent by client equipment, wherein the user log is an operation behavior log of a user on the client equipment;
the target information is Did information of the client device, and after step S33, the method further includes:
and positioning the problem of user feedback based on the Did information of the client equipment and the user log.

In this way, the server device may parse the Did information of the client device from the target screenshot, and may locate the abnormal problem of the user when operating on the client device based on the user log.
The method can be applied to the scene of user feedback problems, the flow of the user feedback problems can be optimized through the method, the user can trigger the report of the user log only by executing the screen capture operation, the device Did information is written into the screen capture obtained by the screen capture operation, and technicians can position the problem of the user feedback according to the screen capture and the user log received by the server device.

Therefore, the target information steganographically written in the target screenshot can be obtained by extracting and analyzing binary bit data of a plurality of pixel point positions in the received target screenshot, and the target information is transmitted through the target screenshot.
