In addition, once these user personal information data are no longer needed, the risks should be minimized by limiting or even prohibiting data collection and / or deleting data.

[0031] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0032] With the existing on-site service fulfillment method, it is difficult to verify the authenticity of the completed photos received by the system. Since the source and content of the photos can be controlled by the photographer, the authenticity and credibility of the photos cannot be ensured. The photographer may forge photos or tamper with the on-site situation to cover up problems or deceive users, which is not conducive to subsequent dispute resolution, quality traceability, etc., and cannot meet actual needs well.

[0033] In order to solve the above-mentioned problems existing in the prior art, the present invention proposes a method for fulfilling door-to-door service, which completes the fulfillment of door-to-door service by uploading door-to-door service check-in information with location information and embedding the completion information of the door-to-door service into the completion photo in an encrypted manner, thereby achieving more reliable and secure door-to-door service fulfillment, improving the authenticity of the completion photos, ensuring the fulfillment quality of the door-to-door service, and enhancing the trust of merchants and users.

[0034] In the introduction to the embodiments of the present invention, the terms and their meanings are as follows:

[0035] KeyChain: A secure storage mechanism. Information saved in the keychain will not be lost due to uninstalling / reinstalling the app.

[0036] UUID: refers to a number generated on a machine, which is guaranteed to be unique to all machines in the same time and space;

[0037] LSB replacement algorithm: An image steganography technique that replaces the least significant bit (LSB) of the pixel value of an image with the information to be hidden, without noticeably changing the appearance of the image.

[0038] Figure 1 FIG. 1 is a schematic diagram of the main process of the on-site service fulfillment method according to an embodiment of the present invention. Figure 1 As shown, the door-to-door service fulfillment method of the embodiment of the present invention includes the following steps S101 to S102.

[0039] Step S101: in response to receiving a door-to-door service sign-in request, uploading sign-in information with location information to a service end so as to verify and confirm the sign-in information.

[0040] Specifically, when a user purchases an item that includes door-to-door service, the server dispatches the work according to the transaction order information and assigns the door-to-door service task to the corresponding door-to-door staff. The staff receives the door-to-door service task to be executed through the handheld terminal, agrees on the door-to-door service time with the user, provides door-to-door service at the agreed time, and sends a sign-in request through the door-to-door service application APP of the handheld terminal when arriving at the door-to-door service destination. The door-to-door service application APP receives the sign-in request, obtains the current geographical location information of the sign-in requester, and uploads the sign-in information with the location information to the server, so that the server compares and verifies the location information in the received sign-in information with the door-to-door service address in the order corresponding to the door-to-door service task. The location information within one kilometer of the order address is determined as a sign-in request that has passed the verification. If the verification fails, a prompt message will be sent to the requester through the door-to-door service application APP, notifying the requester to sign in again within one kilometer of the door-to-door service address. The one-kilometer judgment value supports flexible configuration as needed. After the server confirms that the sign-in information has passed the verification, the staff is allowed to perform subsequent door-to-door service related operations through the APP.

[0041] According to one embodiment of the present invention, before uploading the check-in information with location information to the server, the method also includes: collecting the device identification of the device used by the requester based on the registration request received from the requester of the door-to-door service check-in request; storing the device identification in the form of a keychain so that the server can confirm the validity of the device used.

[0042] Specifically, in order to effectively supervise the performance of door-to-door service, before uploading the check-in information with location information to the server, the server needs to confirm the validity of the device that sends the check-in information. The specific validity confirmation is achieved through the device identifier UUID. The requester of the check-in request, that is, the door-to-door service staff, needs to register when using the door-to-door service application APP for the first time, and send a registration request to the APP. The APP collects the UUID of the device used by the requester and stores the UUID in the handheld terminal in the form of KeyChain to ensure that after the UUID is generated once, the UUID cannot be deleted even if the APP is uninstalled. When the requester logs in to the APP for the first time, the stored UUID is transmitted to the server. The server establishes a binding relationship between the requester and the UUID, so that the subsequent requester can first authenticate the device where the APP is located when using the APP to confirm its validity.

[0043] According to another embodiment of the present invention, uploading the check-in information with location information to the server includes: obtaining the location information of the requester of the door-to-door service check-in request; generating the check-in information according to the location information and the personal information of the requester; and sending the check-in information to the server.

[0044] Specifically, when the APP receives the check-in information containing the requester's personal information, it obtains the requester's current geographic location information, where the personal information can be text information with the check-in person's name and unit name, or human features such as the check-in person's fingerprint, face, iris, voiceprint, etc. The geographic location information and personal information are integrated and processed into check-in information, and the integrated check-in information is sent to the server, so that the server can verify and confirm the check-in information based on the location information and personal information.

[0045] Step S102: When the door-to-door service is completed, the completion information is encrypted according to the received key and the encryption algorithm, the encrypted information is embedded in the completion photo, and the embedded completion photo is uploaded to the server to complete the performance of the door-to-door service.

[0046] Specifically, when the above-mentioned service end confirms that the check-in information has been verified, the door-to-door staff can prepare to start providing door-to-door services to users, such as installation or repair of home appliances and furniture; housekeeping-related cleaning or accompanying; pet-related bathing or feeding, etc. When the door-to-door service is completed, the staff submits a completion feedback request through the above-mentioned APP, such as adding completion photos in the APP. The APP calls the shooting function of the handheld terminal to take a specified number of completion photos that can represent the completed on-site scene. At the same time, the APP receives the encryption key provided by the key provider. The APP will encrypt the completion information at the current completion moment according to the encryption algorithm, and then fuse the encrypted information into the completion photo. Click to upload the photo to upload the embedded completion photo to the server. Of course, the action of clicking to upload the photo can also trigger the fusion of the encrypted information into the completion photo to be uploaded, and the server receives the embedded completion photo.

[0047] According to an embodiment of the present invention, the key is generated by the server, and the server generates the key when confirming that the usage device is a valid device.

[0048] Specifically, the key provider of the present invention can be a server, and a key generation device is deployed in advance on the server. When the server receives the completion feedback request submitted by the APP, it first needs to verify whether the device used by the current staff is a valid device, that is, it is necessary to re-verify the device in use. Obtain the UUID of the device that issued the completion feedback request, and check from the binding relationship between the staff and UUID stored internally whether the requester and the UUID of the device in the completion feedback request are consistent with the binding relationship between the staff and UUID stored internally. If they are consistent, it means that the device in use is a valid device, and the corresponding encryption key and decryption key are generated according to the requester information and UUID. If they are inconsistent, a prompt message is issued and the encryption key is not provided.

[0049] Through the above-mentioned equipment validity in the completion photo submission process and the embedded processing of completion information, the problem of door-to-door service staff submitting false information using non-registered equipment is avoided. Among them, the confirmation of the validity of the equipment used is convenient for standardized management on the one hand, and on the other hand, it can also ensure that the completion photos are not tampered with by restricting the handheld terminal from loading software with photo editing functions, thereby ensuring the authenticity of the completion photos received by the server.

[0050] According to another embodiment of the present invention, when the encryption algorithm is an asymmetric encryption algorithm, the completion information is encrypted according to the received key and the encryption algorithm, and the encrypted information is embedded in the completion photo, including: encrypting the completion information using an asymmetric encryption algorithm according to the received public key; and embedding the encrypted information in the completion photo in the form of a digital watermark through a least significant bit replacement algorithm.

[0051] According to yet another embodiment of the present invention, the completion information includes: requester information of the door-to-door service check-in request, a geographical location where the door-to-door service is completed, and a time when the door-to-door service is completed.

[0052] Specifically, when the encryption algorithm is an asymmetric encryption algorithm, the encryption key generated by the server is the public key of the asymmetric encryption algorithm, and the decryption key is the private key of the asymmetric encryption algorithm. The server saves the decryption private key and sends the public key. When the door-to-door service application APP receives the public key, it uses the public key to encrypt the completion information using the asymmetric encryption algorithm, where the completion information is key information related to this door-to-door service, for example, it may include: the requester information of the above-mentioned sign-in information, that is, the photographer information of the completion photo; the order information corresponding to the door-to-door service; the address location of the completion, that is, the shooting location of the completion photo; the time of the completion of the door-to-door service, that is, the shooting time of the completion photo, etc. In order to simplify the completion information, the requester information of the door-to-door service sign-in request that can represent the completion status, the geographical location of the door-to-door service completion, and the time of the door-to-door service completion are selected as the completion information.

[0053] Furthermore, the encrypted information is stego-written into the completed photo in the form of a digital watermark using a least significant bit (LSB) replacement algorithm. In addition, for the integration of the location information in the above-mentioned sign-in information, when the personal information is a sign-in photo, the sign-in location information can also be submitted in the same way as the completed information, and an encryption key can be obtained. After the location information is encrypted using the encryption key, the sign-in location information is stego-written into the sign-in photo in the form of a digital watermark using a least significant bit replacement algorithm.

[0054] It can be understood that after receiving the completion information uploaded by the APP, the server reads the digital watermark hidden in the completion photo through an image processing task, and uses the corresponding private key to decrypt the digital watermark, and converts the decrypted real completion information into a real visible watermark, embeds it into the completion photo, and obtains the completion photo showing the completion information, which is then stored in the database. This not only facilitates the identification of the authenticity of the completion photo, but also facilitates subsequent dispute resolution and quality traceability.

[0055] Through the above-mentioned encryption and steganographic processing of the completion information, the privacy of the completion information is protected, and the visual effect of the completion photos is not affected. The reliability and authenticity of the completion photos can be processed without the staff's perception, so as to further ensure that the staff consciously and standardizedly perform the door-to-door service.

[0056] According to another embodiment of the present invention, before uploading the finished photo after embedding processing to the server, the method further includes: checking whether the finished photo contains a preset image, and if the finished photo contains a preset image, blurring the image.

[0057] Specifically, considering that the subject of the completed photo is a scene, usually in the user environment, and because of the staff's order scheduling tasks, the shooting time is very short. For the personal privacy involved in the user environment, there is a possibility that personal privacy will be photographed in the completed photo. For example, in the installation service of a washing machine, if the user's ID card, bank card and other items are currently placed on the washing machine, the staff may take pictures of the ID card and bank card when photographing the completed state of the washing machine after installation. For this reason, when the APP receives the completed photo, it will check whether the completed photo contains images involving user privacy such as ID cards, bank cards, medical insurance cards, cash, etc. If checked, these images will be blurred to protect the user's privacy.

[0058] Figure 2This is a complete flow diagram of the performance of the door-to-door service of an embodiment of the present invention. When the door-to-door service staff uses the door-to-door service application APP for the first time, the UUID of the device is generated by the registration activity and stored in the handheld terminal using KeyChain. The staff logs in to the APP, and the APP obtains the UUID and passes it to the server, so that the server can establish a binding relationship between the person and the device to verify the validity of the device. When the staff arrives near the destination of the door-to-door service, they use the APP to sign in for the door-to-door service and send the sign-in information to the server. The server first authenticates the device according to the UUID, confirms the validity of the sign-in device, and then verifies the sign-in information to confirm that the sign-in information verification passes. The staff starts to provide door-to-door service to the user. When the door-to-door service is completed, a completion feedback request is sent. The completion feedback request received by the server verifies the device again according to the UUID of the device of the completion feedback request and the requesting party. After the verification passes, the corresponding encryption public key and decryption private key are generated and the encryption public key is issued. The staff takes a photo of the completed work in the APP through a handheld terminal. The APP uses the public key to encrypt the completion information of this on-site service, embeds the encrypted information into the completed photo in the form of a digital watermark, and uploads the embedded completed photo to the server. The server uses the decryption private key to decrypt the digital watermark in the completed photo to obtain the corresponding completion information, and then verify the authenticity of the completed photo. Finally, the completion information is explicitly embedded in the completed photo and stored.

[0059] The door-to-door service fulfillment is completed by uploading the door-to-door service check-in information with location information and implicitly embedding the door-to-door service completion information into the completion photo in the form of encrypted digital watermark. This realizes a more reliable and secure door-to-door service fulfillment method, improves the authenticity of the completion photo, ensures the fulfillment quality of the door-to-door service, and enhances the trust between merchants and users.

[0065] According to yet another embodiment of the present invention, the key is generated by the server, and the server generates the key when confirming that the device being used is a valid device.

[0066] According to another embodiment of the present invention, when the encryption algorithm is an asymmetric encryption algorithm, the completion upload module 302 is further used to: encrypt the completion information using an asymmetric encryption algorithm according to the received public key; and embed the encrypted information into the completion photo in the form of a digital watermark through a least significant bit replacement algorithm.

[0067] According to another embodiment of the present invention, the door-to-door service fulfillment device 300 further includes an image processing module (not shown in the figure), which is used to: before uploading the embedded processed completion photo to the server, check whether the completion photo contains a preset image, and if the completion photo contains a preset image, blur the image.
