Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.
In order to provide a convenient and low-cost authentication method, embodiments of the present application provide an authentication method, apparatus, and computer-readable storage medium, which provide a new authentication manner through optical camera communication technology. The optical camera communication technology can utilize the monitoring equipment to acquire the first OCC code displayed by the equipment to be verified, so that communication can be completed. The transmission rate of the optical camera communication technology is limited by the shooting frame rate of the optical camera, and the transmission distance is short, so the optical camera communication technology can be used for short-distance small-capacity data transmission and has the advantage of low cost.
The optical communication technology (or optical camera communication technology) is to use an optical camera to shoot an optical signal that flashes at a specific frequency from a communication source (such as a mobile terminal like a mobile phone or a tablet computer), so as to complete communication, that is, to receive and process visible light data through an image sensor in the camera. In other words, the optical communication technology is an optical communication that uses an image sensor as a receiver, that is, it is characterized in that an image sensor used in a camera detects an optical signal.
The verification method provided by the embodiment of the application is that the equipment to be verified displays a first Optical Camera Communication (OCC) code by using an Optical device such as a flashing light and a screen, the monitoring equipment obtains the first OCC code displayed by the Optical device of the equipment to be verified, converts the first OCC code into the code to be verified, compares the code to be verified with a first comparison code obtained in advance, and finally determines whether the equipment to be verified passes verification according to a comparison result, so that verification can be achieved.
In addition, the use scenes of the verification mode are wide (for example, the scenes of an access control system, a locker and the like are all applicable), and the method also has the advantages of low cost and easiness in popularization.
In order to facilitate understanding of the technical solution of the present application, a device to be authenticated is taken as the mobile terminal 110 to be authenticated, and a monitoring device is taken as the optical camera 120 for description. Those skilled in the art will appreciate that the same considerations in fig. 1 apply to other devices to be authenticated and/or other monitoring devices.
Fig. 1 is a schematic diagram illustrating an operating environment 100 of an authentication method provided by an embodiment of the present application. As shown in fig. 1, both the optical camera 120 and the mobile terminal 110 to be verified can obtain the same comparison code sent by the backend server, that is, the first comparison code and the second comparison code are the same. The to-be-verified mobile terminal 110 converts the received comparison code into a first OCC code, and displays the first OCC code to the optical camera 120 through a screen of the to-be-verified mobile terminal 110. The optical camera 120 converts the acquired first OCC code into a corresponding to-be-verified code, and the optical camera 120 further compares the to-be-verified code with the received comparison code, and determines whether the band mobile terminal 110 passes verification according to the comparison result.
The first OCC code may be an optical signal flashing at a specific frequency, or may be regarded as modulated optical data sent by the mobile terminal 110 to be verified.
For example, the first OCC code may be black picture data displayed on the screen of the mobile terminal 110 to be verified (that is, at this time, the screen of the mobile terminal 110 to be verified is all displayed in black, and the remaining color picture data are similar and will not be described one by one in the following), or white picture data, where the black picture data or the white picture data is used to represent binary data, the black picture data may be used to represent 1, and the white picture data may be used to represent 0.
It should be understood that the specific frequency is not the same as the screen refresh frequency. The screen refresh rate refers to the speed at which an image is updated on the screen, i.e. the number of times an image appears on the screen per second, and the maximum value of the screen refresh rate is limited by the performance of the hardware. For example, the screen refresh rate is the rate at which the mobile terminal refreshes at which the screen refresh rate is that rate regardless of what the handset displays, whether it is a picture or a web page. However, the specific frequency refers to a baud rate (or symbol transmission efficiency) indicating the number of symbol symbols transmitted per second, in other words, the baud rate refers to the number of symbols transmitted through the channel per second, and the baud rate is also an index of the bandwidth of the transmission channel, i.e. the baud rate of the first OCC code is changed according to the surrounding environment.
To facilitate understanding of the relationship between the baud rate and the screen refresh frequency, the following description is made by way of specific examples.
For example, in the case where the screen refresh frequency is 120 hertz (Hz), 120Hz means that the refresh of the screen is 120 pictures in 1 second. And if the first OCC code is binary data and the Baud rate is 8 Baud, then 15 frames of picture output display a black frame data or a white frame data, i.e. 15 frames of picture output for outputting "1" or "0".
In addition, although the above illustrates the case where the first comparison code and the second comparison code are the same, it should be understood by those skilled in the art that the first comparison code and the second comparison code may also be different, and specifically refer to the following contents, and will not be described in detail here.
The first comparison code may be a random code sent by the backend server, or may also be data corresponding to the optical camera 120 sent by the backend server according to an identifier of the optical camera 120 (for example, a model of the optical camera 120), and the embodiment of the present application is not limited to this.
The second comparison code may be a random code sent by the background server, or may also be data corresponding to the mobile terminal 110 to be verified, which is sent by the background server according to the identifier of the mobile terminal 110 to be verified (such as the model of the mobile terminal 110 to be verified), and the embodiment of the present application is not limited to this.
It should be understood that the device to be authenticated and the monitoring device may be the same type of device or may be different types of devices. For example, the device to be authenticated may also be an LED light.
It should also be understood that the device type of the device to be verified and the device type of the monitoring device may be set according to actual requirements of the user, and the embodiment of the present application is not limited thereto.
For example, the device to be verified may also be a camera and a data processing device (e.g., an MCU (micro controller Unit) connected to a signal, where the camera and the data processing device may be an all-in-one device or may be two separate devices connected to a signal.
Fig. 2 shows a flowchart of a verification method provided in an embodiment of the present application. The verification method comprises the following specific steps:
step S210, the device to be verified acquires the second comparison code sent by the background server.
In step S210, the user may send a comparison code sending request (or a verification request) to the background server by operating the operation interface of the device to be verified, where the comparison code sending request is used to enable the background server to send the second comparison code to the device to be verified.
In order to facilitate understanding of the technical solution of the present application, the embodiments of the present application take a device to be verified as a mobile phone as an example for description.
For example, the user can obtain the geographic location (e.g., latitude and longitude coordinates) of the mobile phone through the positioning function of the mobile phone. Subsequently, under the condition that the current position of the user is acquired, the user can select the corresponding verification function through a verification service list displayed in an operation interface of the mobile phone. The verification service list may include a verification scenario (e.g., verification of an access control system and/or verification of a courier cabinet, etc.) near the current location. Subsequently, when the user selects the corresponding authentication function, the mobile phone sends an authentication request to the background server, where each authentication request may include an identification number of the mobile phone, an identification number of the selected monitoring device, and other identifications in order to distinguish the authentication requests of the mobile phones of different users in the current area. Finally, the server sends a second comparison code to the mobile phone of the user based on the received verification request.
In addition, although the manner of obtaining the second comparison code in step 210 is exemplified in a manner that the user operates the operation interface of the device to be verified, it should be understood by those skilled in the art that the second comparison code may also be sent to the device to be verified by the background server itself, and the obtaining process does not need to be manually operated, and the embodiment of the present application is not limited thereto.
For example, the background server obtains the running state information of the device to be verified, where the running state information can be used to obtain the running state of the device to be verified. When the background server determines that the running state of the device to be verified is over-saturated (for example, when the device to be verified is a computer, the running speed of the computer is slow due to more running tasks of the computer), the background server sends a second comparison code to the device to be verified, so that the device to be verified can inform a user of the running state of the device to be verified through the first OCC code displayed on a display of the device to be verified.
It should be understood that, although the manner of obtaining the second comparison code through the backend server is described in step S210, those skilled in the art should understand that the second comparison code may also be stored in the device to be verified itself, and the embodiment of the present application is not limited thereto.
Step S220, the monitoring device obtains the first comparison code sent by the background server.
In step S220, when the background server receives the verification request sent by the device to be verified, the background server may also send the first comparison code to the monitoring device in the process of sending the second comparison code to the device to be verified, where the sent first comparison code and the sent second comparison code are the same.
It should be understood that, in addition to the above-mentioned case that the first comparison code and the second comparison code are the same, the first comparison code and the second comparison code may be different, which will be described later and will not be described in detail herein.
In addition, although the manner in which the background server sends the first comparison code to the monitoring device in step 220 is exemplified, it should be understood by those skilled in the art that the first comparison code may also be pre-stored by the monitoring device, and the embodiment of the present application is not limited thereto.
In step S230, the device to be verified converts the second comparison code into the first OCC code.
In step S230, since the optical camera communication technology uses the optical device such as the display of the device to be verified as the transmission source, and the second comparison code sent by the backend server must be converted into a signal that can be received by the monitoring device, the second comparison code needs to be modulated, that is, the second comparison code is converted into the first OCC code.
In addition, since optical noise exists in the transmission process of the first OCC code, it is necessary to add check bits in the first OCC code.
For example, a start bit, a stop bit and a parity bit are set in the first OCC code, wherein the start bit indicates the start of the transmission data of the first OCC code, and the start bit is set to facilitate the monitoring device to determine the start position of the first OCC code during the cyclic exhibition of the first OCC code; the stop bit indicates the termination of the transmission data of the first OCC code, and is set to facilitate the monitoring equipment to determine the stop position of the first OCC code during the cyclic exhibition of the first OCC code; the parity bits are for the monitoring device to determine the validity of the first OCC code.
In step S240, the device to be verified displays the first OCC code to the monitoring device, so that the monitoring device can determine whether the device to be verified passes the verification through the first OCC code.
In step S240, in the case that the device to be verified is within the shooting range of the monitoring device, the first OCC code may be presented to the image sensor in the monitoring device through the screen of the device to be verified. In addition, in order to ensure that the image sensor in the monitoring device can shoot the screen of the device to be verified, the user can ensure that the image sensor in the monitoring device can shoot the screen of the device to be verified by adjusting the standing posture.
In addition, in the process of displaying the first OCC code by the device to be verified, a lot of optical noise exists in the surrounding environment, so that the problem that the detection difficulty of the first OCC code is relatively large is caused. And the detection difficulty of the first OCC code is increased due to environmental factors such as different use environments of the equipment to be verified, the number of surrounding pedestrians and the number of mobile phone screens.
Therefore, in order to reduce the difficulty of detecting the first OCC code, at least one specific area may be set in the shooting range of the image sensor of the monitoring device, so that the first OCC code is displayed in the specific area, and the difficulty of identifying the first OCC code can be reduced.
In addition, since the first comparison code and the second comparison code are valid for a preset time (for example, 10S), that is, the first comparison code and the second comparison code are time-efficient, the security is greatly improved. It should be understood that the specific time of the preset time may be set according to actual requirements, and the embodiment of the present application is not limited thereto.
In addition, the second comparison code corresponding to the first OCC code displayed by the device to be verified may be different from or the same as the first comparison code stored in the monitoring device.
For example, in the process of converting the first OCC code by the device to be verified, due to the influence of the performance of the device to be verified, when the second comparison code is converted, the second comparison code has exceeded its valid time, that is, the second comparison code is invalid at this time. Or the first comparison code acquired by the monitoring device is updated, so that the second comparison code corresponding to the first OCC code displayed by the device to be verified is different from the first comparison code stored in the monitoring device.
In addition, in a case where different colors can represent different bit values, in order to increase the verification speed, the information transmission speed may be adjusted by adjusting the color of the picture corresponding to the first OCC code, so as to adjust the verification speed, and the embodiment of the present application is not limited thereto.
For example, in the case where the black picture data can represent 1 bit and the red picture data can represent two bits, fast transmission can be achieved by adjusting the current black picture data to the red picture data.
Step S250, the monitoring device obtains the first OCC code displayed by the device to be verified.
It should be understood that the first OCC code acquired by the monitoring device and the first OCC code displayed by the device to be verified may be the same or different. For example, under the condition that the first OCC code acquired by the monitoring device has an error code, the first OCC code acquired by the monitoring device is different from the first OCC code displayed by the device to be verified.
In step 250, the image sensor of the monitoring device can acquire image data containing the device to be verified, and then the monitoring device can extract the first OCC code from the image data.
For example, when the monitoring device collects multiple frames of images including a device to be verified, the monitoring device may perform the following processing on each frame of image: since the image may contain different information of the user, the device to be verified, and the like, the monitoring device may determine a specific location in the image, where the specific location corresponds to the specific area. After the specific position in the image is determined, human body recognition, gesture recognition and object recognition (or recognition of the device to be verified) can be sequentially performed on the characteristic position to determine the data displayed by the device to be verified in each frame of image. And the monitoring equipment identifies a plurality of data from the multi-frame image and acquires a plurality of first OCC codes based on the start bit and the stop bit of the first OCC codes.
It should be understood that, for the first OCC code, in the process of cyclically displaying the first OCC code by the device to be verified, the first OCC data after the conversion of the second comparison code may be regarded as one first OCC code. Of course, the first OCC data after the second comparison code conversion may also be regarded as a plurality of first OCC codes, and the embodiment of the present application is not limited thereto.
Correspondingly, the time for circularly displaying the first OCC code by the device to be verified may also be set according to actual requirements, and the embodiment of the present application is not limited to this.
In addition, in order to ensure the transmission accuracy of the first OCC code, in the process of displaying the first OCC code by the device to be verified, the device to be verified should be prevented from moving in a large range.
Step S260, the monitoring device converts the first OCC code into a to-be-verified code.
In step S260, the monitoring device demodulates the obtained first OCC codes into a plurality of codes to be verified, respectively, where the first OCC codes are obtained by cyclically displaying the codes by the device to be verified.
It should be understood that the modulation method for converting the first comparison code into the first OCC code by the device to be verified corresponds to the demodulation algorithm for converting the first OCC code into the code to be verified by the monitoring device.
In step S270, the monitoring device compares the code to be verified with a first comparison code obtained in advance, and obtains a comparison result.
It should be understood that the pre-obtained first comparison code may also be a first comparison code that is sent by the backend server simultaneously during the process of sending the second comparison code to the device to be verified, or may also be a first comparison code that is sent by the backend server to the monitoring device earlier, and the embodiment of the present application is not limited to this.
In step S270, the monitoring device may compare the plurality of codes to be verified with the first comparison code, so as to determine a plurality of comparison results, where the comparison results are similar proportion values of the codes to be verified and the first comparison code, the similar proportion values represent ratios of the same code bits in the first comparison code and the codes to be verified to the total code bits, and the same code bits refer to the same positions and the same values in the first comparison code and the codes to be verified.
For example, in order to simply describe the comparison result, the following description is made with the to-be-verified code and the first comparison code respectively including 4 bits. In the case where the first comparison code is "0100" and the code to be verified is "0001", since the 1 st bit and the 3 rd bit of the first comparison code are the same as the 1 st bit and the 3 rd bit of the code to be verified, the similarity ratio value of the first comparison code to the code to be verified is 2/4.
In step S280, the monitoring device determines whether the device to be verified passes the verification according to the comparison result.
In step S280, because the device to be verified moves and the transmission of the first OCC code is unreliable, and the first OCC code received by the monitoring device is prone to have an error code caused by an nonresistance factor, it is necessary to obtain the accuracy (or similar ratio) of the first OCC data received multiple times and remove a plurality of data with too low accuracy, and average the accuracy of the remaining data, specifically:
here, when obtaining a plurality of similarity ratio values of a plurality of codes to be verified, the average value of the remaining similarity ratio values may be obtained by removing too low data in the plurality of similarity ratio values. And when the average value is greater than or equal to a preset accuracy threshold (or a preset similarity ratio threshold), determining that the device to be verified passes verification, whereas when the average value is less than the preset accuracy threshold, determining that the device to be verified does not pass verification.
It should be understood that the preset accuracy threshold may be set according to actual requirements, and the embodiment of the present application is not limited thereto.
In addition, when the device to be verified does not pass verification, re-verification is required, and the re-verification process may be set according to actual requirements, which is not limited in the embodiments of the present application.
For example, the re-authentication process is to re-execute step S210 to step S280. For another example, the re-verification process is to re-execute step S230 to step S280.
In addition, the monitoring device can also realize the monitoring function on the basis that the monitoring device has the verification function, so that the verification device of the embodiment of the application can be obtained by improving the existing device (for example, the camera device for monitoring).
In summary, the embodiment of the present application provides a new verification method through an optical camera communication technology, that is, a first OCC code displayed by a device to be verified is obtained, the first OCC code is converted into a code to be verified, the code to be verified is compared with a first comparison code obtained in advance, and finally, whether the device to be verified passes verification is determined according to a comparison result, so that the new verification method can conveniently achieve verification, and can reduce verification cost by using the advantage of low cost of the optical camera communication technology.
That is to say, this application embodiment just can realize verifying through obtaining the first OCC code of the show of waiting to verify equipment, need not the user to record complicated password to can realize convenient verification process. In addition, due to the low-cost characteristic of the optical camera communication technology, the embodiment of the application realizes verification by utilizing the characteristic of the optical camera communication technology, and can also realize a low-cost verification mode.
In order to facilitate understanding of the technical solutions of the present application, the following detailed descriptions are provided by specific examples.
Fig. 3 shows a specific flowchart of an authentication method provided in an embodiment of the present application, where the authentication method may use a screen of a mobile terminal as a signal source for transmitting a specific signal, and a high definition camera receives the signal, so as to achieve a user authentication purpose.
