Furthermore, the embodiments described below are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
Fig. 1 is a schematic structural diagram of a picture information processing system according to an exemplary embodiment of the present application. As shown in fig. 1, the system includes: a vehicle-side terminal 101 and a server 102. The terminal 101 and the server 102 may be in communication connection.
The vehicle has an advertisement area for displaying advertisement information, and the terminal 101 on the vehicle side runs an application installed on the terminal 101 with certain account information. For convenience of description and distinction, a vehicle for displaying advertisement information is referred to as a target vehicle, an application in the terminal 101 installed on the target vehicle is referred to as a target application, and account information running the target application is referred to as target account information.
The kind and size of the target vehicle are not limited in this embodiment, as long as the advertisement display area is provided and advertisement information can be displayed. The target vehicle may be, for example, a large-sized vehicle, a medium-sized vehicle, a small-sized vehicle, or the like. The kind of the target vehicle may be, for example, a container vehicle, a pick-up truck, a taxi, a family car, a passenger car, or the like.
The present embodiment does not limit the implementation form of the terminal 101 on the target vehicle. The terminal 101 may be, for example, a smart handheld device, such as a smart phone, tablet computer; may be a smart wearable device, such as a smart bracelet; but also desktop devices such as notebook computers. The terminal 101 is provided with a target application, and the target application may be an independent APP or an applet embedded in the independent APP, which is not limited in this embodiment.
The implementation manner of the server 102 is not limited in this embodiment. The server 102 may be deployed on a virtual machine, a cloud server, a cloud host, or a physical machine, for example. Alternatively, the server 102 may be deployed in a centralized manner on one physical machine or one virtual machine, or may be deployed in a distributed manner on multiple physical machines or multiple virtual machines.
In this embodiment, the terminal 101 on the target vehicle may implement communication connection with the server 102. The communication connection may be a wired or wireless communication connection. Optionally, in the case of a wireless communication connection, the two devices may be communicatively connected via a mobile network; accordingly, the network system of the mobile network may be any one of 2G (GSM), 2.5G (GPRS), 3G (WCDMA, TD-SCDMA, CDMA2000, UTMS), 4G (LTE), 4g+ (lte+), 5G, wiMax or a new network system that will be in the future. Optionally, the two devices may also be located in the same local area network, and in the case of wireless communication connection, each device may also implement communication connection through bluetooth, wiFi, infrared, zigbee, NFC, or the like.
In an advertising application scenario, related photos of the advertising situation of a car body at the current time need to be uploaded periodically to verify the validity of the car body advertisement during an advertisement contract. However, propaganda parties of car body advertisements may use photos taken in advance before the current time to cheat so as to mask branding parties, that is, the existing scheme for verifying the validity of car body advertisements has the problem of lower accuracy. In order to solve the problem of lower accuracy, the embodiment of the application provides the following scheme: the terminal application of the target vehicle can prevent cheating actions of selecting pictures for verification tasks from pre-shot pictures by advertising personnel by prohibiting the function of accessing the terminal gallery; further, the terminal application adds a target watermark in the first picture which is currently shot in real time and contains the first advertisement information to obtain a second picture, so that the server 102 verifies the validity of the second picture based on the target watermark in the second picture, a verification threshold is added for verifying the validity of the advertisement information, and verification difficulty is improved; based on the above, whether the first advertisement information contained in the second picture is the target advertisement information is verified under the condition that the second picture is effective, the accuracy of verifying the target advertisement information can be improved, and therefore the accuracy of a scheme for verifying the effectiveness of the target advertisement information is improved.
In an application scenario, the server 102 is provided with a task of sending a verification task according to a preset time period, and when the preset time period is reached, the server 102 sends a sending instruction of the verification task, and sends the verification task to the terminal 101 in response to the sending instruction of the verification task, wherein the verification task includes a requirement of a size of a picture to be shot by the terminal 101 on the side of the target vehicle. The size requirement of the photographed picture may be, for example, the shape and size of the picture, but is not limited thereto.
Correspondingly, the terminal 101 receives the verification task for the target advertisement information sent by the server 102, and calls the camera of the terminal 101 to shoot the advertisement area on the target vehicle according to the size requirement in response to the verification operation for the verification task, so as to obtain a picture containing the advertisement information. For convenience of description and distinction, the advertisement information included in the first picture is referred to as first advertisement information, and the picture including the first advertisement information is referred to as a first picture.
In this embodiment, in response to the verification operation of the verification task, after the target application receives the verification task, a verification control is displayed in a graphical user interface displayed by the terminal 101, and in response to the touch operation of the verification control, a camera of the terminal 101 is automatically invoked to shoot an advertisement area on the target vehicle, so as to obtain a first picture. This manner is merely illustrative, but not limiting.
It should be noted that the target application prohibits the use of the function of directly accessing the terminal gallery. The function of directly accessing the terminal gallery is forbidden, so that the cheating action can be prevented by selecting the picture for executing the verification task from the pictures shot in advance. That is, the accuracy of verifying the vehicle body advertisement is ensured from the stage of acquiring the first picture.
Further, the verification task sent by the server 102 further includes a watermark added in the first picture. The implementation of the watermark may be, for example, but not limited to, a company Logo, a specific number or letter, and combinations thereof of the propaganda party, depending on the specific requirements. For convenience of description and distinction, a watermark added in a photographed picture is referred to as a target watermark. The pixel value of the target watermark is not limited in this embodiment, and may be a larger pixel value or a smaller pixel value. Preferably, the pixel value of the target watermark is less than or equal to 1KB. When the pixel is smaller than or equal to 1KB, the target watermark is invisible, so that the target watermark is more concealed, and the difficulty of identifying or tampering with the target watermark is increased.
Accordingly, the terminal 101 may add the target watermark to the first picture to obtain the first picture to which the target watermark is added, so as to improve the verification difficulty for the first picture and improve the accuracy of verifying the vehicle body advertisement. For convenience of distinction and description, the first picture to which the target watermark is added is referred to as a second picture.
Further, the terminal 101 sends the second picture to the server 102, and accordingly, the server 102 receives the second picture sent by the terminal 101. Further, the server 102 verifies the validity of the second picture based on the target watermark included in the second picture, and verifies whether the advertisement information included in the second picture is the set advertisement information to be advertised in the case that the second picture is valid. For convenience of description and distinction, the advertisement information included in the second picture is referred to as first advertisement information, and the advertisement information set to be advertised is referred to as target advertisement information.
The server 102 may verify the validity of the second picture based on the target watermark included in the second picture, for example, compare the target watermark included in the second picture with a set watermark (also referred to as a reference watermark) stored in the server 102, and determine that the second picture is valid if the two watermarks are identical. For other preferred implementations of the server 102 verifying the validity of the second picture based on the target watermark included in the second picture, reference may be made to the related descriptions of the following embodiments, which are not described herein in detail.
Similarly, if the second picture is valid, it is verified whether the first advertisement information included in the second picture is a specific implementation manner of the target advertisement information, for example, the first advertisement information included in the second picture may be compared with the set advertisement information (also referred to as the target advertisement information) stored in the server 102, and if the two reference information are identical, it is determined that the first advertisement information included in the second picture is the target advertisement information.
According to the technical scheme provided by the embodiment of the application, the terminal application of the target vehicle can inhibit the function of accessing the terminal gallery, so that cheating behaviors of advertisement propaganda staff selecting pictures for verification tasks from pre-shot pictures can be prevented; further, the terminal application adds a target watermark in a first picture which is currently shot in real time and contains the first advertisement information to obtain a second picture, so that the server side verifies the validity of the second picture based on the target watermark in the second picture, a verification threshold is added for verifying the validity of the advertisement information, and verification difficulty is improved; based on the above, whether the first advertisement information contained in the second picture is the target advertisement information is verified under the condition that the second picture is effective, the accuracy of verifying the target advertisement information can be improved, and therefore the accuracy of a scheme for verifying the effectiveness of the target advertisement information is improved.
In an alternative embodiment, the verification task further includes task description information, where the task description information includes at least a task name, a task start time, and a task end time. The task name is the name of the verification task, and still takes the application scene of advertisement propaganda as an example, and the task name can be, for example, an advertisement information verification task. The photographing time information and the photographing position information are both time information and position information for photographing the first picture.
Accordingly, when the terminal 101 is configured to add the target watermark to the first picture to obtain the second picture, the method is specifically configured to: acquiring the type, shooting position information and shooting time information of a terminal; the type of the terminal can be, for example, the equipment model of the terminal, and the shooting time information is located between the task starting time and the task ending time; further, a combined character string is determined based on the task name, the task start time, the task end time, the type of the terminal, the photographing position information, and the photographing time information; further, determining target position information of the target watermark in the first picture based on the combined character string; and then, adding the target watermark into the first picture according to the target position information to obtain a second image.
Alternatively, the terminal 101 is specifically configured to, when used for determining a combination string based on a task name, a task start time, a task end time, a type of terminal, shooting position information, and shooting time information: based on the task name, the task starting time, the task ending time, the type of the terminal, the shooting position information and the shooting time information, performing character conversion operation of a preset character type to obtain a character string corresponding to each item of information; further, according to the arrangement and combination mode among the set information items, the character strings corresponding to each item of information are arranged and combined, and the combined character strings are obtained.
The preset character type is not limited in this embodiment, and may be, for example, octal, decimal, hexadecimal, or the like. The preset character types are different, the conversion modes are also different, and the corresponding converted character string types can be the same or different. However, whatever preset character type is used for conversion, the following conversion method may be used (where 'U' represents a character and 'ch' represents a character string):
the method comprises the following steps: character. Tostring (), was used. The Character class provides a static method toString () for converting characters into strings. The following are provided: char ch= 'U'; string chartoString =Character. Tostring (ch).
The second method is as follows: a string connector is used. When string connectors are used, other types of variables are automatically converted to string types. The following are provided: char ch= 'U'; string= 'ch'.
And a third method: an anonymous array (anonymous array) is used. The anonymous array in java may be used to encapsulate a single character into an array of characters, which is then used as the constructor parameter for String. The following are provided: char ch= 'U'; string from char=new String (New char [ ] { ch }).
The method four: string.valueof (). The following are provided: char ch= 'U'; string valueOfchar =
String.valueOf(ch)。
In this embodiment, the verification task further includes a plurality of candidate location information of the target watermark. The plurality of candidate location information is determined by the server 102 before the server 102 transmits the authentication task to the terminal 101. The server 102, when used for determining a plurality of candidate positions of the target watermark, is specifically configured to: based on the preset length and width of the picture template, carrying out grid division on the picture template according to a preset division size to obtain a grid diagram of the picture template, wherein the grid diagram at least comprises a plurality of grid areas, and size information and position information of each grid area; further, based on the size information and the position information of each grid area, determining candidate position information in each grid area, and obtaining a plurality of candidate position information for adding watermark information in a picture template; further, the plurality of candidate position information, the task start time and the task end time are added to the verification task together and sent to the terminal 101, so that the terminal 101 determines the target position information of the target watermark in the first picture based on the plurality of candidate position information.
Optionally, the foregoing mesh dividing the picture template according to the preset dividing size based on the preset length and width of the picture template to obtain the mesh map of the picture template, for example, the picture template may be uniformly divided according to four rows and three columns, the picture template may be uniformly divided according to four rows and four columns, and the picture template may be unevenly divided, which is not limited in this embodiment. The size information may be information such as a length or a width of each mesh region, and the position information may be information describing a position of each mesh region such as an upper left, a lower right, an upper right, a lower left, a row, a column, and the like.
Alternatively, candidate location information in each grid region is determined based on the size information and the location information of each grid region, and the specific embodiment thereof is as follows: one or more preset positions in each grid area are selected as candidate positions in each grid area, wherein the preset positions can be positions such as center points or corner points of each grid area.
Further, after obtaining the plurality of candidate location information, the server 102 adds the plurality of candidate location information, the task start time and the task end time to the verification task together, and sends the verification task to the terminal 101, so that the terminal 101 determines the target location information of the target watermark in the first picture based on the plurality of candidate location information.
Optionally, the terminal 101, when configured to determine, based on the combined string, target location information of the target watermark in the first picture, is specifically configured to: taking the combined character string as a reference, and calculating by using a hash algorithm model to obtain a hash value of the combined character string, wherein the step of calculating by using a hash algorithm can refer to the existing calculation mode and is not repeated here; further, dividing the hash value as a divisor, and the number of the plurality of candidate position information as a dividend to obtain a remainder; then, the remainder is used as the code for selecting the target position information, and the position information corresponding to the code among the plurality of candidate position information is used as the target position information.
It should be noted that each candidate location of the plurality of candidate locations has a unique code. For example, one of the positions may be used as a starting point (i.e., code 1) and the codes may be sequentially performed in a clockwise direction or a counterclockwise direction. For another example, each candidate position may be randomly encoded as long as each candidate position can be distinguished. For example, the plurality of candidate positions are encoded as 1, 2, 3, 4, 5, 6, respectively; and dividing the number of the plurality of candidate position information serving as the divisor by taking the hash value as the divisor to obtain remainder 2; and taking the candidate position corresponding to the code 2 as the position of the target watermark in the first picture, and taking the candidate position information corresponding to the code 2 as the target position information of the target watermark in the first picture.
After obtaining the target position information of the target watermark in the first picture, the target application of the terminal 101 is specifically configured to, when adding the target watermark to the first picture according to the target position information to obtain the second image: selecting one or more character strings from character strings corresponding to each item of information of task name, task starting time, task ending time, type of terminal, shooting position information and shooting time information, namely a first character string, and adding a target watermark into the first character string; and adding the target watermark into the first picture according to the target position information, and adding the first character string added with the target watermark and other character strings not added with the target watermark into the first picture to obtain a second picture. Adding the target watermark to one or more character strings further increases the difficulty of verifying the picture by the server 102, thereby improving the accuracy of the scheme for verifying the validity of the target advertisement information.
It should be noted that, after determining the target position information of the target watermark in the first picture and the first string added with the target watermark, the target position information and the first string added with the target watermark need to be sent to the server 102 for storage, so that the server 102 verifies the validity of the second picture.
Further, after obtaining the second picture, the terminal 101 needs to send the second picture to the server 102. In an alternative embodiment, the process of sending the second picture to the server 102 by the terminal 101 is specifically as follows: the terminal 101 responds to the first triggering operation of the picture uploading control, and sends a first uploading request of a second picture to the server 102, wherein the first uploading request at least comprises equipment information of the terminal 101; the server 102 receives a first uploading request for the second picture sent by the terminal 101, and calls a setting data interface to send a target token to the terminal 101 in response to the first uploading request, wherein the token can be understood as an authentication key for authenticating a task; the terminal 101 receives the target token returned by the server 102. Further, the terminal 101 responds to the second triggering operation of the picture uploading control, and sends a second uploading request of a second picture to the server 102, wherein the second uploading request at least comprises a target token; correspondingly, the server 102 receives a second uploading request for the second picture sent by the terminal 101, performs matching verification based on a target token included in the second uploading request and a locally stored reference token, and sends a request instruction for the second picture to the terminal 101 when the target token verification is passed; accordingly, the terminal 101 sends the second picture to the server 102 in response to the request instruction for the second picture sent by the server 102.
The target token may be a reference token, or a dummy token generated by the server 102 based on the device information of the terminal 101 and the reference token. Specifically, the data limiting rule is set in the set data interface, and in this embodiment, the content of the limiting rule is not limited, and the limiting rule may be a rule that limits the uploaded data arbitrarily, so as to improve the security of data uploading. Such as whether the type or content of the data, etc., meets the requirements of the restriction rules. Still taking the verification scenario of advertisement information as an example, in the application scenario, the restriction rule may be to restrict the same terminal 101 to upload advertisement propaganda pictures of different vehicles. The above examples are illustrative only and are not intended to be limiting.
It should be further noted that, if the uploaded data accords with the constraint rule, the server 102 directly sends the reference token as the target token to the terminal 101 through the set data interface; if the uploaded data does not meet the constraint rule, the server 102 generates a false token according to the device information of the terminal 101 and the reference token, and sends the false token as a target token to the terminal 101 through a set data interface.
