In all the drawings, similar elements or parts are generally identified by similar reference numerals. In the drawings, the elements or parts are not necessarily drawn according to the actual scale.

[0047] Figure 1 A flowchart of an automated management method for electronic signatures on a smart logistics platform is provided for an embodiment of the present invention;

[0048] Figure 2 A structural schematic diagram of an automated electronic signature management system for a smart logistics platform is provided for an embodiment of the present invention. DETAILED DESCRIPTION

[0049] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0050] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0051] Example 1

[0052] like Figure 1 As shown, an embodiment of the present invention provides an automated management method for electronic signatures on a smart logistics platform, the method comprising:

[0053] Step 1: Obtain the user's electronic signature call request, which includes a logistics business contract, an electronic signature identifier, and a user identity identifier.

[0054] Specifically, the electronic signature call request mainly consists of three parts: the logistics business contract is the core document that the user wants to electronically sign, which describes in detail the terms and details of the logistics business; the electronic signature identifier is the unique identification code of the specific electronic signature selected by the user. In the smart logistics platform, there may be a variety of different electronic signatures, each with its own unique identifier. Through this identifier, the system can accurately identify the electronic signature that the user wants to use. The user identity identifier is the user's unique identification information, which is used to verify the identity of the user who initiated the electronic signature call request. In the logistics business, it is crucial to ensure that the user's identity is authentic and reliable.

[0055] Step 2: Determine the user level, electronic signature level and signature risk based on the electronic signature identifier and user identifier; determine the mapping function parameters of the user level in the electronic signature based on the difference between the electronic signature level and the user level, and map the user level to the electronic signature split point through the mapping function parameters.

[0056] In an embodiment of the present invention, the user level, electronic signature level and signature risk are determined according to the electronic signature identification and user identification, including: obtaining historical signature data according to the electronic signature identification and user identification, wherein the historical signature data includes signing frequency, time since last signing, degree of change in signing location and frequency of equipment replacement; performing weighted calculation on the historical signature data to determine the signature risk; performing identity authentication once when the signature risk is less than or equal to a preset value, and performing identity authentication twice when the authentication risk is greater than a preset value; when the identity authentication passes, obtaining the electronic signature level according to the electronic signature identification, and obtaining the user level according to the user identification.

[0057] Specifically, the historical signature data covers the user's signing frequency (i.e., the number of times the user has performed a signing operation within a period of time), the time interval since the last signing, the degree of change in the signing location (reflecting the geographical stability of the user's signing behavior), and the frequency of device replacement (reflecting the environmental stability of the user's signing behavior). The above historical signature data is weighted to determine the risk of the signature. The weighted calculation takes into account the importance of different factors in assessing the risk. For example, the signing frequency may be considered a more important factor, while the frequency of device replacement may be relatively minor. A comprehensive signature risk can be derived through weighted calculation.

[0058] Specifically, this embodiment determines the number of verifications based on the signature risk. If the signature risk is less than or equal to the preset value, it means that the user's signature behavior is relatively stable and the risk is low, and only one identity verification is required. On the contrary, if the signature risk is greater than the preset value, it means that the user's signature behavior may be abnormal or high-risk, so two identity verifications are required to improve security.

[0059] The identity verification method includes but is not limited to key verification, SMS verification, and biometric verification.

[0060] This embodiment comprehensively considers the user's historical signing behavior, the characteristics of the electronic signature, and the result of identity verification, and dynamically determines the user level, electronic signature level, and risk level of the signature, which provides a solid foundation and accurate basis for obtaining the electronic signature in subsequent steps.

[0061] In an embodiment of the present invention, the method for determining the degree of change of the signing location includes: obtaining historical signature positions; clustering the historical signature positions according to the historical signature positions and the signature position self-learning algorithm to obtain the signature position centroid; obtaining the current signature position, and calculating the signature distance between the current signature position and the signature position centroid; when the signature distance is less than the set distance, determining the degree of change of the signing location according to the signature distance.

[0062] It should be noted that the signature position self-learning algorithm provided in the embodiment of the present invention is an improved algorithm. The algorithm does not need to pre-set the K value. It directly treats the historical signature position (location) as a cluster for each historical signature position, and then continuously merges the two closest clusters until the distance between the two farthest points in the same cluster meets the preset distance threshold.

[0063] The improved algorithm provided by the embodiment of the present invention is more suitable for the field of logistics management. This is because due to the location change characteristics of logistics, the signature locations are generally not concentrated in one area or multiple areas. Therefore, the specific number of clusters K cannot be determined.

[0064] In the embodiment of the present invention, the formula for mapping the user level to the electronic signature split point through the mapping function parameter is:

[0065]

[0066] Where λx, λy, μx, μy are mapping function parameters, H is the user level, and L x and L y They are the maximum values ​​of the electronic signature contour in the x and y directions respectively.

[0067] Step 3: offset the electronic signature splitting point according to the electronic signature risk and the preset electronic signature risk, and obtain the electronic signature splitting graph according to the offset result; the splitting graph includes a key point and several splitting areas, each splitting area corresponds to an encrypted storage mechanism, and the key point is used to overlap with the electronic splitting point to realize the electronic signature splitting.

[0068] The split area is a different area divided around the key point, and each area corresponds to a specific encryption storage mechanism. In this way, when the electronic signature is split, different fragments can be encrypted and stored in different areas, further enhancing the security of the signature.

[0069] In an embodiment of the present invention, the electronic signature split point is offset according to the electronic signature risk and the preset electronic signature risk, and the electronic signature split graph is obtained according to the offset result, including: determining an offset function according to the difference between the electronic signature risk and the preset electronic signature risk; offsetting the electronic signature split point according to the offset function to obtain a target electronic signature split point; calculating the Euclidean distance between the target electronic signature split point and the electronic signature split point; determining an offset according to the Euclidean distance, and determining the electronic signature split graph according to the offset.

[0070] In an embodiment of the present invention, the electronic signature split point is offset according to the offset function to obtain a target electronic signature split point, including: offsetting the electronic signature split point according to the offset function to obtain an offset point; when the offset point is on or within the outline of the electronic signature, using the offset point as the target electronic signature split point; when the offset point is not outside the outline of the electronic signature, using the intersection of the offset point and the electronic signature split point as the target electronic signature split point.

[0071] The above method can be used to obtain the electronic signature splitting graph, and then restore the corresponding electronic signature.

[0072] Step 4: dynamically retrieve and decrypt the electronic signature fragments according to the electronic signature splitting points and the electronic signature splitting graph, and reassemble the decrypted electronic signature fragments to obtain the electronic signature.

[0073] Specifically, according to the electronic signature splitting points and splitting graphics determined by the splitting graphics system, the corresponding electronic signature fragments are located in the storage system, and then the decryption algorithm and key are determined according to the encryption storage mechanism of each split area in the splitting graphics, and the stored electronic signature fragments are decrypted; the decryption process strictly follows the encryption storage mechanism set for each splitting area to ensure the security and accuracy of the decryption operation. Then all the decrypted electronic signature fragments are reassembled according to the layout of the splitting graphics to restore the complete electronic signature image.

[0074] Step 5: Use the electronic signature to sign the logistics business contract to complete the contract signing process.

[0075] In summary, an embodiment of the present invention provides an automated management method for electronic signatures of a smart logistics platform, the method comprising: obtaining an electronic signature call request of a user, the electronic signature call request comprising a logistics business contract, an electronic signature identifier and a user identity identifier; determining a user level, an electronic signature level and a signature risk according to the electronic signature identifier and the user identifier; determining a mapping function parameter of the user level in the electronic signature according to the difference between the electronic signature level and the user level, and mapping the user level to an electronic signature splitting point through the mapping function parameter; offsetting the electronic signature splitting point according to the electronic signature risk and a preset electronic signature risk, and obtaining an electronic signature splitting graph according to the offset result; the splitting graph comprises a key point and a plurality of splitting areas, each splitting area corresponds to an encrypted storage mechanism, and the key point is used to overlap with the electronic splitting point to realize electronic signature splitting; dynamically retrieving and decrypting electronic signature fragments according to the electronic signature splitting point and the splitting graph, and recombining the decrypted electronic signature fragments to obtain an electronic signature; signing the logistics business contract using the electronic signature to complete the contract signing process. The present invention provides a method for dynamically encrypting and storing electronic signatures taking into account user level, electronic signature level and signature risk, thereby avoiding leakage of electronic signatures and providing an effective identity authentication mechanism to avoid tampering with electronic signatures by unauthorized users.
