[0002] The existing assessment methods for attendance check-in of home visit services mainly include mobile Bluetooth check-in or QR code check-in, combined with on-site image verification at the service location. The staff connects the attendance device they are equipped with to the on-site verification device, and then transmits it to the backend for consistency assessment. If the verification is passed, the attendance is successful, and then the on-site photo of the service location is taken for verification; through the connection between the attendance device and the verification device and the on-site photo, it is determined that the staff's attendance is valid for this time.

[0058] The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0059] To facilitate the understanding of the present invention, the present invention will be described more comprehensively 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, these embodiments are provided to make the disclosure of the present invention more thorough and comprehensive.

[0060] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the description of the present invention herein 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.

[0061] Embodiment 1

[0062] Please refer to Figure 1, shown is the anti-cheating method for home visit services in the first embodiment of the present invention. The anti-cheating method for home visit services specifically includes steps S10 to S20:

[0063] S10, in response to the staff's attendance operation, obtain the first dynamic code in the corresponding attendance device of the staff and the second dynamic code in the verification device at the service location;

[0064] In specific implementation, the staff is equipped with corresponding attendance devices, and the homes of the serviced objects are installed with corresponding attendance verification devices; since the serviced objects do not need to pay themselves, they do not pay much attention to the service duration, service frequency, etc. of the staff, and most of them do not actively feedback to the monitoring center. Therefore, there may be a large number of situations where the staff is absent or absent from work and the monitoring center is unaware.

[0065] Optionally, in this embodiment, when responding to the staff's attendance operation, such as performing Bluetooth communication connection, etc., timely obtain the first dynamic code in the corresponding attendance device of the staff and the second dynamic code in the verification device at the service location.

[0066] S20, perform code matching on the first dynamic code and the second dynamic code;

[0067] Optionally, step S20 specifically includes:

[0068] If the code matching is successful, it is determined that the staff has no previous attendance cheating behavior, and the attendance device is communicatively connected to the verification device;

[0069] Encrypt the attendance data in the attendance device, and send the encrypted attendance data to the verification device for interactive synchronization to update the first dynamic code and the second dynamic code;

[0070] Obtain the continuous communication connection time between the attendance device and the verification device, and determine whether the continuous communication connection time meets the preset requirements;

[0071] If the continuous communication connection time meets the preset requirements, record that the staff's current working hours are qualified and the current attendance is valid. If the continuous communication connection time does not meet the preset requirements, record that the staff's current working hours are insufficient and the current attendance is invalid;

[0072] If the code matching is unsuccessful, it is determined that the staff has used a copying device for attendance and there is an attendance cheating behavior.

[0073] Optionally, in this embodiment, if the attendance device and the verification device have matching codes, they will be automatically connected. 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 a 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. The next time the staff member punches in at the service location or the original verification device is randomly inspected, since the verification device at the service location has not been updated, the information written by the staff member's attendance device does not match the information of the verification device at the service location, and it can be inferred that the staff member has committed an attendance cheating act of using a copied device to punch in.

[0074] Further, after it is determined that the staff member has not committed any attendance cheating acts in the past when the code matching is successful, it is also necessary to determine whether the staff member leaves immediately 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 member has been at the service location all the time, the working hours for this time are qualified, and the attendance for this time is valid, preventing the attendance cheating act of the staff member leaving immediately after punching in.

[0075] Optionally, in this embodiment, the step of encrypting the attendance data in the attendance device, sending the encrypted attendance data to the verification device for interactive synchronization, and updating the first dynamic code and the second dynamic code includes:

[0076] Mark the attendance device as trustworthy and store the trust mark in the verification device;

[0077] 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;

[0078] Encrypt and interactively synchronize 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.

[0079] Further, the expression of the trust mark is , the expression of the first shared key is , the expression of the verification key is , the expression of the second shared key is , where is the th attendance device, is the number of sessions between the attendance device and the verification device;

[0080] The step of encrypting, interacting and 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:

[0081] The attendance device uses the first shared key to encrypt the attendance data, and sends the trusted identifier and the encrypted attendance data to the verification device;

[0082] The verification device identifies the corresponding attendance device based on the stored trusted identifier and verifies based on the corresponding verification key If , the verification passes, the second shared key is updated , and the verification key is updated to complete the update of the second dynamic code;

[0083] The verification device sends the updated second shared key to encrypt the attendance data and feedback it to the attendance device;

[0084] After receiving the encrypted data, the attendance device uses the first shared key to verify. If , the verification passes, the first shared key is updated to complete the update of the first dynamic code.

[0085] In this embodiment, a combined verification dynamic method using a shared key and a verification key can be iterated scrollingly, and the characteristics of synchronous update of two devices can be applied to an environment of one-to-many verification and key negotiation to achieve dynamic update and verification between devices; it can be understood that there may be personnel flow during work, and door-to-door services may be provided for different staff at different times, and the corresponding attendance devices are different, but the verification device is fixed and installed in the home of the service recipient; the combined verification dynamic method using a shared key and a verification key is particularly suitable for wireless communication targets; the key in the device participates in local updates and does not need to be sent, reducing the update calculation amount and saving protocol resources.

[0086] In some alternative embodiments, after communicatively connecting the attendance device and the verification device, the anti-cheating method for home door-to-door services further includes:

[0087] Sending a first shooting instruction to the staff, where the first shooting instruction requires the staff to shoot a panoramic image of the service location;

[0088] In response to the obtained panoramic image, randomly select a target area to be further photographed in the panoramic image;

[0089] Send a second shooting instruction to the staff after a preset time, where the second shooting instruction requires the staff to shoot a target image of the target area;

[0090] Match the target image with a partial image within the target area to determine whether the target image shot by the staff is the image required by the second shooting instruction, and further determine whether the attendance of the staff is valid.

[0091] The step of matching the target image with a partial image within the target area includes:

[0092] Perform a matching operation on the feature points in the panoramic image and the feature points in the target image. The matching operation includes:

[0093] Optionally select a matching point in each of the panoramic image and the target image as the center matching point, and respectively select two matching points in the two images according to a preset circular neighborhood;

[0094] Based on the two matching points and the center matching point within the circular neighborhood, form corresponding triangles in the two images respectively. Among them, the triangle in the panoramic image is denoted as the first triangle, and the triangle in the target image is denoted as the second triangle;

[0095] Determine whether the first triangle and the second triangle are similar;

[0096] If they are similar, determine that the three matching points on the first triangle match the three matching points on the second triangle;

[0097] Repeat the above matching operation until all feature points in the partial image within the target area and all feature points in the target image have been selected, so as to complete the matching of the target image and the partial image within the target area.

[0098] The expression for determining the similarity of the first triangle and the second triangle is:

[0099]

[0100]

[0101] 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 threshold value of the opposite side ratio difference is the threshold value of the angle difference

[0102] Optionally, in order to prevent the staff from performing attendance cheating operations where, after successfully punching the card, they immediately place the attendance device at the home of the service recipient and then leave. At this time, the attendance card punching is successful and the continuous communication connection time also meets the requirements; however, in this case, the staff still does not provide effective service duration. Therefore, after the attendance device of the staff is successfully connected to the verification device, a first shooting instruction is sent to the staff, requiring to shoot a panoramic image of the service location. A second shooting instruction is sent to the staff within a preset time to shoot an image of a partial target area of the service location; since the preset time and the target area can be randomly selected according to the situation, even if the staff pre-shoots several images of the service location, it is difficult to match the images required by the shooting instruction; greatly reducing the possibility of attendance cheating.

[0103] In summary, the anti-cheating method for home visit services provided by this application first responds to the staff's attendance operation, obtains the dynamic code of the attendance device and the dynamic code of the service location verification device correspondingly, performs code matching, and judges whether the staff has ever had attendance cheating behavior based on the matching result. If the matching is successful, the dynamic code in the attendance device is encrypted and updated and synchronized to the verification device for the next card punching verification to prevent the staff from using a replicated device for attendance. Further, continuously obtain the connection time between the attendance device and the verification device, and judge the working hours of the staff according to the continuous connection time to prevent the staff from leaving the service location immediately after punching the card and performing attendance cheating; the anti-cheating method for home visit services provided by this application can effectively prevent the staff from using a replicated device for punching the card and attendance cheating behavior with insufficient working hours, and is suitable for large-scale promotion.
