[0002] In the process of signing for express parcels using related technologies, the courier selects a recipient and then signs for the parcel. However, the courier company cannot guarantee that the courier has actually contacted the recipient and accurately delivered the parcel to the recipient. When there are parcels to be delivered, they are prone to being lost, causing losses to the recipient. Summary of the Invention

[0027] Specifically, in the embodiments of this specification, server 01 may include a standalone server, a distributed server, or a server cluster composed of multiple servers. It may also be a cloud server providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms. Server 01 may include a network communication unit, a processor, and a memory, etc. Specifically, server 01 can be used to encrypt the recipient's account identifier using a dynamic encryption algorithm to generate a delivery code and send it to the recipient and the pickup platform. It can also send a reminder message to the corresponding recipient of the express package to provide the delivery code based on the delivery code's delivery category; and compare the real-time delivery code sent by the recipient with the delivery codes stored in the pickup platform, and dispatch the package based on the comparison result.
[0028] Specifically, in the embodiments of this specification, the client 02 may include physical devices such as smartphones, desktop computers, tablets, laptops, digital assistants, smart wearable devices, smart speakers, in-vehicle terminals, and smart TVs. It may also include software running on the physical device, such as web pages provided to users by service providers, or applications provided to users by such service providers. Specifically, the client 02 can be used to display a notification message for the receipt code.
[0029] The following describes a method for signing for express parcels using a signature code, based on the present invention. Figure 2 This is a flowchart illustrating a method for signing for a package using a delivery code, as provided in an embodiment of this specification. This specification provides the operational steps described in the embodiments or flowchart, but based on conventional or non-inventive methods, more or fewer operational steps may be included. The order of steps listed in the embodiments is merely one possible execution order among many and does not represent the only possible execution order. In actual system or server product execution, the methods shown in the embodiments or drawings can be executed sequentially or in parallel (e.g., in a parallel processor or multi-threaded processing environment). Specifically, as shown... Figure 2 As shown, the method may include: S201: When it is determined that the express package is a signed package with a signature code, a signature category identifier of the express package is generated, and the recipient's account identifier corresponding to the express package is obtained. In the embodiments of this specification, the recipient account identifier may include, but is not limited to, the recipient's mobile phone number, contact information, etc. The type of delivery receipt may include, but is not limited to, door-to-door delivery, storage at a courier station, or other receipt methods. Among these, receipt code signing refers to the courier obtaining a receipt code from the recipient, then entering the code during delivery to complete the package delivery, thereby preventing delivery errors.
[0030] S203: The recipient account identifier is encrypted using a dynamic encryption algorithm to generate a receipt code, which is then sent to the recipient and the pickup platform.
[0031] In the embodiments of this specification, a signature code is generated according to a dynamic generation algorithm, and the signature code is sent to the recipient synchronously. The encrypted signature code is also sent to the courier's pickup and delivery terminal.
[0032] S205: In response to the courier's scanning instruction for the signature category identifier corresponding to the express package, the express package is displayed as a signature code signature category, and the express package is marked as a signature code signature package.
[0033] In the embodiments described in this specification, each express parcel is equipped with a signature category identifier. The courier scans this identifier using a delivery terminal, and the terminal interface displays the signature code of the express parcel as the signature category; thus, the express parcel is marked as a signed-for parcel. When there are multiple express parcels, they can be classified according to the signature category, and all parcels marked as signed-for parcels can be retrieved and signed for using the signature code.
[0034] S207: During the delivery process of the express parcel, a reminder message to provide the signature code is sent to the corresponding recipient of the express parcel according to the signature code signature category.
[0035] In this embodiment, the delivery code sending platform randomly generates a 4-digit code based on the recipient's mobile phone number and sends a text message to the recipient with the message: "Hello, your package with tracking number xxxxxxxxxxxxxxx is about to be delivered. Please provide this 4-digit 'xxxx' delivery code to complete the delivery." For packages signed for using a delivery code, during the delivery process, in response to the delivery person's delivery code retrieval instruction triggered based on the delivery code category, a reminder message to provide the delivery code can be sent to the corresponding recipient. When a delivery code SMS is generated for a package requiring delivery code signing, the system responsible for generating the delivery code will synchronize the generated delivery code to the delivery person's pickup and delivery app.
[0036] S209: Receive the real-time receipt code sent by the recipient according to the reminder message, and compare the real-time receipt code with the receipt code stored in the pickup platform to obtain the comparison result.
[0037] In this embodiment of the specification, after a package arrives at the delivery point, the courier sorts it according to the markings on the waybill. The courier then scans the package to claim it. If the package is a signed-for item, the courier will be prompted to use the signed-for code. Couriers typically place these packages separately in their vehicles. Before delivery, the courier will contact the recipient in advance by phone to arrange a suitable delivery time and remind them to prepare the signed-for code for quick and easy signing upon receipt. After scanning the package, the courier enters the signing interface, inputs the signed-for code provided by the recipient, and compares it. If the comparison is successful, intelligent verification is performed. After the courier scans and claims the package to be delivered, the order will be marked as a signed-for item in the courier's pending signature list. The signed-for code is stored locally in the app and is not displayed to the courier; it is only used for comparison.
[0038] S2011: When the comparison result is a match, the express parcel is delivered to the recipient.
[0039] In the embodiments of this specification, when the comparison result is a matching result, it means that the signature code provided by the recipient is consistent with the signature code stored on the pickup platform. At this time, the express package is delivered to the recipient, thereby ensuring that the express package is delivered without error and improving the delivery accuracy of the express package.
[0040] In this embodiment of the specification, the step of encrypting the recipient account identifier using a dynamic encryption algorithm to generate a delivery receipt code includes: Obtain the current timestamp, the tracking number of the express package, and the geofence parameters; The current timestamp is subjected to quantum random number perturbation to generate an encrypted timestamp; A second hash operation is performed on the waybill number of the express package to extract the parity check bit as a feature code and generate a digital receipt code. Obtain at least one of the recipient's receiving device identifier and the courier's delivery device identifier; The digital signature code is encrypted based on at least one of the receiving device identifier and the delivery device identifier to generate the signature code; and the correspondence between the signature code, the encrypted timestamp, and the geofence parameters is stored in a preset database.
[0041] In the embodiments of this specification, a receipt code is generated in real time based on a multi-dimensional dynamic encryption algorithm. This algorithm integrates the current timestamp, the waybill number feature value, and the geofence parameter. During the generation process, the current time is subjected to quantum random number perturbation processing to ensure the unpredictability of the time factor. At the same time, a secondary hash operation is performed on the waybill number to extract the parity check bit as a feature code. The generated 6-digit receipt code is encrypted in segments using the AES-256 encryption algorithm. The first 3 digits are bound to the recipient's mobile phone IMEI code, and the last 3 digits are associated with the courier's device ID. The encrypted receipt code is synchronized to the message queue via the MQTT protocol and pushed to the recipient's SMS gateway and the courier's pickup and delivery APP respectively. The push process adopts a dual-channel verification mechanism. On the basis of traditional SMS sending, encrypted notifications are simultaneously pushed to the recipient's mobile device through the FCM service to ensure the reliability of reception. At the same time, the timestamp, encryption key, and other metadata of the receipt code are stored in the blockchain storage module to form an immutable distribution record.
[0042] In this embodiment of the specification, the step of encrypting the digital signature code based on at least one of the receiving device identifier and the delivery device identifier to generate the signature code includes: Parse the first and second strings in the digital signature code; The first string is encrypted based on the receiving device identifier to generate first encrypted data; The second string is encrypted based on the delivery device identifier to generate second encrypted data; The first encrypted data and the second encrypted data are concatenated to generate the receipt code.
[0043] In the embodiments of this specification, the first string and the second string can be determined based on the number of characters in the digital signature code. For example, a 6-digit digital signature code is segmented and encrypted using the AES-256 encryption algorithm. The first three digits are extracted as the first string and bound to the recipient's mobile phone IMEI code. The last three digits are extracted as the second string and associated with the courier's device ID. The encrypted signature code is synchronized to a message queue via the MQTT protocol. Finally, the encrypted first and second encrypted data are concatenated to generate the signature code.
[0044] In the embodiments of this specification, after encrypting the recipient account identifier using a dynamic encryption algorithm to generate a delivery code, the method further includes: If the recipient has multiple express packages delivered on the same day, the signature code will be determined as the signature code corresponding to the multiple express packages. Store the correspondence between the tracking number and the signature code for each express package.
[0045] In the embodiments of this specification, if the same recipient has multiple packages that require a signature code for receipt on the same day, the 4-digit signature code sent on the same day will be the same to facilitate the recipient in providing the signature code. If a package that is not delivered on the same day requires a signature code for receipt, the signature code sent may be different. Each signature code will have the 15-digit tracking number of the package.
[0046] In the embodiments described in this specification, such as Figure 3 As shown, receiving the real-time delivery confirmation code sent by the recipient according to the reminder message includes: S301: If a message is received from the recipient indicating that the signature code has not been received or has been accidentally deleted, in response to the triggering operation of resending the signature code in the signature code signing interface, the signature code is resent to the recipient. S303: Receive the real-time receipt code sent by the recipient based on the received receipt code.
[0047] In the embodiments described in this specification, when the recipient does not receive the signature code, the courier clicks the resend button, and a new dynamic signature code is generated during the resend.
[0048] To prevent recipients from missing the delivery code SMS due to communication issues or accidentally deleting the delivery code SMS, this function provides an "Resend Delivery Code" option. When the courier clicks "Resend Delivery Code," the delivery code for that order will be immediately resent to the recipient. After the recipient provides the delivery code, the courier enters the code, compares it, and completes the delivery.
[0049] When a recipient reports not receiving the delivery confirmation code, the courier clicks the resend button to trigger the intelligent resend process. The system first activates a frequency control mechanism, checking the number of resends for this order within a preset time period (e.g., 1 hour). If the limit is exceeded, it automatically switches to the voice verification code channel. During resend, the system generates a completely new dynamic delivery confirmation code based on a quantum random number generator, while simultaneously updating the timestamp and geofencing parameters to ensure the uniqueness of the new code. To prevent abuse of resends, the system introduces a behavioral analysis model to conduct risk assessments on recipients who frequently request resends.
[0050] In the embodiments described in this specification, such as Figure 4 As shown, the step of receiving the real-time delivery code sent by the recipient according to the reminder message, and comparing the real-time delivery code with the delivery code stored in the pickup platform to obtain the comparison result includes: S401: Receive the real-time delivery confirmation code sent by the recipient according to the reminder message; S403: In response to the scanning operation of the signature port of the express parcel, display the signature code signature interface; S405: In response to the input operation of the real-time receipt code on the receipt code receipt interface, the real-time receipt code is displayed on the receipt code receipt interface; S407: Compare the real-time receipt code with the receipt code stored in the pickup platform to obtain the comparison result.
[0051] In this embodiment of the specification, when the courier delivers the package, he / she will remind the recipient to provide the 4-digit numeric signature code for the package: (1) When the courier scans the package at the entry point, a signature code will be displayed on the signature interface: (a) After scanning the barcode on the waybill, the 15-digit waybill number is identified. If the waybill number does not conform to the regular expression validation, the message "Waybill number error" will be displayed. If it conforms to the regular expression validation, the waybill number is verified to be correct. If no recipient is selected, the courier will be prompted to select the correct recipient to sign for the package. If a recipient has already been selected, you will be taken to the signature code signing interface. (b) The signature code interface title displays "Signature Code Received"; (c) Show that 15 is the waybill number; (d) Provide a 4-digit signature code input box, and when entering the signature code interface, a numeric keyboard will pop up at the bottom of the page by default. The keyboard provides 10 numbers from 0 to 9, and also provides an "x" delete button to delete or modify the input content; (e) Display the reminder text "Signature code for delivery. Please ask the recipient for the 4-digit SMS signature code and enter it to sign for delivery". (f) After the courier enters the 4-digit signature code, it will automatically compare it with the 4-digit signature code stored locally for this order. If they are the same, the verification is correct and the courier can sign for the package. If they are incorrect, the system will prompt "Please enter the correct signature code" and clear the entered 4 digits so that the courier can re-enter them. (2) The courier directly signs for the package using the signature code in the pending signature list: (a) The "Signing Code Signed" button is displayed. (b) Click "Sign for Delivery Code": If no recipient is selected, the courier will be prompted to select the correct recipient to sign for the package. If a recipient has already been selected, you will be taken to the signature code signing interface. (b) The signature code interface title displays "Signature Code Received"; (c) Show that 15 is the waybill number; (d) Provide a 4-digit signature code input box, and when entering the signature code interface, a numeric keyboard will pop up at the bottom of the page by default. The keyboard provides 10 numbers from 0 to 9, and also provides an "x" delete button to delete or modify the input content; (e) Display the reminder text "Signature code for delivery. Please ask the recipient for the 4-digit SMS signature code and enter it to sign for delivery". (f) After the courier enters the 4-digit signature code, it will automatically compare it with the 4-digit signature code stored locally for the same order. If they are the same, the verification is correct and the courier can sign for the package. If they are incorrect, the system will prompt "Please enter the correct signature code" and clear the entered 4 digits so that the courier can re-enter them.
[0052] In the embodiments described in this specification, such as Figure 5 As shown, comparing the real-time signature code with the signature codes stored in the pickup platform to obtain the comparison result includes: S501: Perform basic format verification on the real-time receipt code to determine whether the real-time receipt code conforms to the preset character format; S503: If the real-time signature code conforms to the preset character format, the parity check bit of the real-time signature code is compared with the waybill number feature of the express package to obtain the initial comparison result. S505: If the initial comparison result is a matching result, obtain the input behavior characteristics of the real-time signature code; S507: Input the input behavior features into the risk scoring model to perform risk scoring prediction and obtain the real-time risk score of the real-time signature code; S509: If the real-time risk score is less than a preset threshold, the real-time receipt code is compared with the receipt code stored in the pickup platform to obtain the comparison result.
[0053] In this embodiment, after the courier scans the waybill barcode, the system automatically retrieves and decrypts the locally cached encrypted delivery code, initiating a three-level verification process: First, basic format verification is performed to check if the input delivery code conforms to a 6-digit number format; second, feature comparison verification is performed, comparing the parity check bit of the input code with the feature code of the waybill number pre-stored in the system; finally, behavioral analysis verification is triggered, and the input behavioral features can include, but are not limited to, 12 dimensions such as input time, input frequency, and geographical location offset; by analyzing the 12 dimensions of behavioral features such as input time, input frequency, and geographical location offset, a real-time risk scoring model is constructed. This predicts the real-time risk score of the real-time delivery code, and a preset threshold corresponding to the real-time risk score is set according to the actual situation. If the real-time risk score is less than the preset threshold, the real-time delivery code is compared with the delivery codes stored in the pickup platform to obtain the comparison result.
