[0018] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 It is a flow chart of the anti-cheating method for home door-to-door service in the first embodiment of the present invention; Figure 2 FIG. 4 is a structural block diagram of a computer in a fourth embodiment of the present invention.

[0020] The following specific implementation manner will further illustrate the present invention in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0021] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0023] Embodiment 1 See also Figure 1 , which shows the anti-cheating method for home door-to-door service in the first embodiment of the present invention, and the anti-cheating method for home door-to-door service specifically includes steps S10 to S20: S10, in response to the staff member performing an attendance operation, obtaining a first dynamic code in the attendance device corresponding to the staff member and a second dynamic code in the verification device at the service location; In the specific implementation, the staff are equipped with corresponding attendance equipment, and the service recipients have corresponding attendance verification equipment installed in their homes. Since the service recipients do not need to pay for it themselves, they will not pay much attention to the service hours and frequency of the staff, and most of them will not take the initiative to report to the monitoring center. Therefore, there may be a large number of staff members absent from work without the monitoring center knowing.

[0024] Optionally, in this embodiment, in response to the staff performing attendance operations, such as establishing a Bluetooth communication connection, etc., the first dynamic code in the attendance device corresponding to the staff and the second dynamic code in the verification device at the service location are obtained in a timely manner.

[0025] S20, performing code matching on the first dynamic code and the second dynamic code; Optionally, step S20 specifically includes: If the codes match successfully, it is determined that the staff member has not cheated in attendance in the past, and the attendance device is connected to the verification device for communication; Encrypting the attendance data in the attendance device, and sending the encrypted attendance data to the verification device for interactive synchronization, so as to update the first dynamic code and the second dynamic code; Obtaining the continuous communication connection time between the attendance device and the verification device, and determining whether the continuous communication connection time meets the preset requirements; If the continuous communication connection time meets the preset requirements, the staff member's working hours are recorded as qualified and the attendance is valid. If the continuous communication connection time does not meet the preset requirements, the staff member's working hours are recorded as insufficient and the attendance is invalid. If the code match fails, it is determined that the staff member has used a copy device to record attendance, which is attendance cheating.

[0026] Optionally, in this embodiment, if the codes of the attendance device and the verification device match, they will automatically connect. Each time the connection is successful, the system will encrypt the attendance data for this time and synchronize the encrypted data to the corresponding verification device. Based on this, if the staff member copies a verification device, when the staff member punches in at a non-service location, the first dynamic code of the attendance device will be automatically updated and synchronized to the copied device. When the staff member punches in at the service location next time or the original verification device is spot-checked, since the verification device at the service location has not been updated, the information written into the staff member's attendance device does not match the verification device information at the service location. It can be inferred that the staff member has committed attendance cheating by using a copied device to punch in.

[0027] Furthermore, when the code is matched successfully and it is determined that the staff has not cheated in the past, it is also necessary to determine whether the staff has left after punching in. Therefore, in this embodiment, the continuous communication connection time between the attendance device and the verification device is obtained. If the continuous communication connection time between the attendance device and the verification device meets the preset requirements, it is considered that the staff has been at the service location, the working hours are qualified, and the attendance is valid, thereby preventing the staff from cheating in attendance by leaving after punching in.

[0028] Optionally, in this embodiment, the step of encrypting the attendance data in the attendance device and sending the encrypted attendance data to the verification device for interactive synchronization to update the first dynamic code and the second dynamic code includes: Conducting a trustworthy identification on the attendance device, and storing the trustworthy identification in the verification device; Define a first shared key for the attendance device to send data to the verification device, a verification key and a second shared key for the verification device to send data to the attendance device; The attendance data is encrypted and interactively synchronized according to the first shared key, the verification key, and the second shared key to update the first dynamic code and the second dynamic code.

[0029] Furthermore, the expression of the trusted identifier is: , the expression of the first shared key is , the expression of the verification key is , the expression of the second shared key is ,in, For the Attendance equipment, The number of sessions between the attendance device and the verification device; The step of encrypting and interactively synchronizing the attendance data according to the first shared key, the verification key, and the second shared key to update the first dynamic code and the second dynamic code includes: The attendance device uses the first shared key Encrypt the attendance data and send the trusted identifier and sending the encrypted attendance data to the verification device; The verification device is based on a stored trusted identity Identify the corresponding attendance device based on the corresponding verification key To verify, if , the verification is successful, and the second shared key is updated , and verification key , complete the update of the second dynamic code; The authentication device sends the updated second shared key Encrypt attendance data and feed it back to the attendance device; After receiving the encrypted data, the attendance device uses the first shared key To verify, if , the verification is successful, and the first shared key is updated , complete the update of the first dynamic code.

[0030] In this embodiment, a dynamic verification method using a shared key and a verification key combination can be used for rolling iterations. The feature of synchronous updates of two devices can be applied to a one-to-many verification and key negotiation environment to achieve dynamic updates and verifications between devices. It is understandable that there may be personnel mobility at work, and door-to-door services may be provided to different staff members at different times. The corresponding attendance devices are different, but the verification devices are fixed and installed in the homes of the service recipients. The dynamic verification method using a shared key and a verification key combination is particularly suitable for wireless communication targets. The keys in the devices participate in local updates and do not need to be sent, which reduces the update calculation amount and saves protocol resources.

[0031] In some optional embodiments, after the attendance device is communicatively connected with the verification device, the home service anti-cheating method further includes: Sending a first shooting instruction to a staff member, wherein the first shooting instruction requires the staff member to shoot a panoramic image of a service location; In response to the acquired panoramic image, randomly selecting a target area to be further photographed in the panoramic image; After a preset time, a second shooting instruction is sent to the staff, wherein the second shooting instruction requires the staff to shoot a target image of the target area; The target image is matched with a partial image in the target area to determine whether the target image photographed by the staff is the image required by the second photographing instruction, and then determine whether the staff's attendance is valid.

[0032] The step of matching the target image with the partial image within the target area comprises: Performing a matching operation on the feature points in the panoramic image and the feature points in the target image, the matching operation comprising: Selecting any matching point in each of the panoramic image and the target image as the center matching point, and selecting two matching points in each of the two images according to a preset circular neighborhood; Based on the two matching points in the circular neighborhood and the center matching point, corresponding triangles are formed in the two images respectively, wherein the triangle in the panoramic image is recorded as a first triangle, and the triangle in the target image is recorded as a second triangle; Determining whether the first triangle and the second triangle are similar; If they are similar, determining that the three matching points on the first triangle match the three matching points on the second triangle; The above matching operation is repeated until all feature points in the partial image within the target area and all feature points in the target image are selected, so as to complete the matching between the target image and the partial image within the target area.

[0033] The similarity determination expression of the first triangle and the second triangle is:

[0034]

[0035] In the formula, is the center matching point in the first triangle, , are the other two matching points in the first triangle except the center matching point, is the center matching point in the second triangle, , are the other two matching points in the second triangle except the center matching point, is the edge ratio difference threshold, is the angle difference threshold.

[0036] Optionally, in order to avoid attendance cheating in which the staff places the attendance device at the home of the service recipient after successfully clocking in and then leaves, the attendance clocking in is successful and the continuous communication connection time also meets the requirements; but in this case the staff still fails to provide effective service time; therefore, after the staff's attendance device is successfully connected to the verification device, a first shooting instruction is sent to the staff, requiring a panoramic image of the service location to be taken, and a second shooting instruction is sent to the staff within a preset time, requiring an image of a partial target area of ​​the service location to be taken; since the preset time and target area can be randomly selected according to the situation, even if the staff has taken images of several service locations in advance, it is difficult to match them with the images required by the shooting instruction; greatly reducing the possibility of attendance cheating.

[0037] In summary, the anti-cheating method for home door-to-door service provided by the present application first responds to the staff's attendance operation, obtains the dynamic code of the attendance device and the dynamic code of the verification device at the service location, performs code matching, and determines whether the staff has cheated in the past based on the matching result. If the match is successful, the dynamic code in the attendance device is encrypted and updated and synchronized to the verification device to facilitate the next clock-in verification, thereby preventing the staff from using a copy device for attendance. Furthermore, the connection time between the attendance device and the verification device is continuously obtained, and the working hours of the staff are determined based on the continuous connection time to prevent the staff from leaving the service location immediately after clocking in and cheating in attendance. The anti-cheating method for home door-to-door service provided by the present application can effectively prevent the staff from using a copy device to clock in and cheating in attendance due to insufficient working hours, and is suitable for large-scale promotion.

If the continuous communication connection time does not meet the preset requirements, the staff member's working hours are recorded as insufficient and the attendance is invalid. If the code match fails, it is determined that the staff member has used a copy device to record attendance, which is attendance cheating.

[0039] The step of encrypting the attendance data in the attendance device and sending the encrypted attendance data to the verification device for interactive synchronization to update the first dynamic code and the second dynamic code includes: Conducting a trustworthy identification on the attendance device, and storing the trustworthy identification in the verification device; Define a first shared key for the attendance device to send data to the verification device, a verification key and a second shared key for the verification device to send data to the attendance device; The attendance data is encrypted and interactively synchronized according to the first shared key, the verification key, and the second shared key to update the first dynamic code and the second dynamic code.

[0042] Wherein, the step of matching the target image with the partial image within the target area comprises: Performing a matching operation on the feature points in the panoramic image and the feature points in the target image, the matching operation comprising: Selecting any matching point in each of the panoramic image and the target image as the center matching point, and selecting two matching points in each of the two images according to a preset circular neighborhood; Based on the two matching points in the circular neighborhood and the center matching point, corresponding triangles are formed in the two images respectively, wherein the triangle in the panoramic image is recorded as a first triangle, and the triangle in the target image is recorded as a second triangle; Determining whether the first triangle and the second triangle are similar; If they are similar, determining that the three matching points on the first triangle match the three matching points on the second triangle; The above matching operation is repeated until all feature points in the partial image within the target area and all feature points in the target image are selected, so as to complete the matching between the target image and the partial image within the target area.
