[0049] The embodiments of the technical solutions of the present application will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present application, and therefore only serve as examples, and cannot limit the protection scope of the present application.

[0050] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in the present application should be understood as the usual meanings understood by the skilled person in the field to which the present application belongs.

[0051] Embodiment 1

[0052] As shown in the drawings, the embodiments of the present application provide a smart logistics platform electronic seal automatic management method, which comprises: Figure 1

[0053] Step 1, obtaining an electronic seal calling request of a user, the electronic seal calling request comprising a logistics business contract, an electronic seal identifier and a user identity identifier.

[0054] Specifically, the electronic seal calling request is mainly composed of three parts: the logistics business contract is the core file that the user hopes to perform electronic seal, which describes in detail the various terms and details of the logistics business; the electronic seal identifier is the unique identification code of the specific electronic seal selected by the user. In the smart logistics platform, there may be many different electronic seals, each seal has its unique identifier. Through this identifier, the system can accurately identify the electronic seal that the user hopes to use. The user identity identifier is the unique identity information of the user, which is used to verify the identity of the user initiating the electronic seal calling request. In the logistics business, it is crucial to ensure the authenticity and reliability of the user's identity.

[0055] ​Step 2, determining the user level, the electronic signature level and the signature risk degree according to the electronic signature identifier and the user identifier; determining the 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 the electronic signature split point through the mapping function parameter.

[0056] In the embodiment of the application, determining the user level, the electronic signature level and the signature risk degree according to the electronic signature identifier and the user identifier comprises: obtaining historical signature data according to the electronic signature identifier and the user identifier, wherein the historical signature data comprises signature frequency, time since the last signature, signature location change degree and device replacement frequency; determining the signature risk degree by weighted calculation on the historical signature data; performing one-time identity verification when the signature risk degree is less than or equal to a preset value, and performing two-time identity verification when the signature risk degree is greater than the preset value; obtaining the electronic signature level according to the electronic signature identifier and obtaining the user level according to the user identifier when the identity verification is passed.

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

[0058] Specifically, the embodiment determines the number of verifications according to the signature risk degree. If the signature risk degree is less than or equal to a preset value, it indicates that the user's signature behavior is relatively stable and low-risk, and one-time identity verification is sufficient. On the contrary, if the signature risk degree is greater than the preset value, it indicates that the user's signature behavior may be abnormal or high-risk, and therefore two-time identity verification is needed to improve security.

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

[0060] The embodiment dynamically determines the user level, the electronic signature level and the signature risk degree by comprehensively considering the user's historical signature behavior, the characteristics of the electronic signature and the results of the identity verification. This provides a solid foundation and accurate basis for the subsequent electronic signature acquisition.

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

[0062] It should be noted that the signing position self-learning algorithm provided in the embodiment of the present application is an improved algorithm, which does not need to set the K value in advance, and directly clusters each historical signing position as a cluster, and then continuously merges the two clusters with the closest distance until the distance between the two points with the farthest distance in the same cluster meets the preset distance threshold.

[0063] The improved algorithm provided in the embodiment of the present application is more suitable for the field of logistics management, because due to the location change characteristics of logistics, the signing positions are generally not gathered in one or more areas, so the specific number of clusters K cannot be determined.

[0064] In the embodiment of the present application, the formula for mapping the user level to the electronic signature splitting point through the mapping function parameters is:

[0065]

[0066] In the formula, λx, λy, μx, μy are mapping function parameters, H is the user level, L x and L y are the maximum values of the contour map of the electronic signature in the x direction and the y direction, respectively.

[0067] Step 3, offsetting the electronic signature splitting point according to the electronic signature risk degree and the preset electronic signature risk degree, and obtaining an electronic signature splitting graph according to the offset result; the splitting graph includes a key point and a plurality of splitting regions, each splitting region corresponds to a specific encryption storage mechanism, and the key point is used to overlap with the electronic splitting point to realize electronic signature splitting.

[0068] Among them, the splitting region is a different region divided around the key point, and each region 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 regions, further enhancing the security of the signature.

[0069] In the embodiment of the present application, the electronic signature split point is offset according to the electronic signature risk degree and the preset electronic signature risk degree, and an electronic signature split pattern is obtained according to the offset result, including: determining an offset function according to the difference between the electronic signature risk degree and the preset electronic signature risk degree; 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 amount according to the Euclidean distance, and determining an electronic signature split pattern according to the offset amount.

[0070] In the embodiment of the present application, 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 in the contour pattern of the electronic signature, taking the offset point as the target electronic signature split point; when the offset point is not out of the contour pattern of the electronic signature, taking the intersection of the offset point and the electronic signature split point as the target electronic signature split point.

[0071] The electronic signature split pattern can be obtained by the above method, and the corresponding electronic signature can be restored.

[0072] Step 4: The electronic signature fragments are dynamically searched and decrypted according to the electronic signature split point and the electronic signature split pattern, the decrypted electronic signature fragments are recombined to obtain an electronic signature.

[0073] Specifically, according to the electronic signature split point and the split pattern determined by the split pattern system, the corresponding electronic signature fragments are located in the storage system, and then the decryption algorithm and the key are determined according to the encryption storage mechanism of each split region in the split pattern, so as to decrypt the stored electronic signature fragments; the decryption process strictly follows the encryption storage mechanism set by each split region, so as to ensure the security and accuracy of the decryption operation. Then, all the decrypted electronic signature fragments are recombined according to the layout of the split pattern to restore the complete electronic signature image.

[0074] Step 5: The logistics business contract is signed by the electronic signature to complete the contract signing process.

[0075] In summary, the embodiment of the present application provides a kind of intelligent logistics platform electronic seal automation management method, which comprises: obtaining the electronic seal calling request of user, the electronic seal calling request includes logistics business contract, electronic seal identification and user identity identification;According to the electronic seal identification and user identity, determine user level, electronic seal level and signature risk degree;According to the difference between the electronic seal level and the user level, determine the mapping function parameter of user level in electronic seal, and map the user level to electronic seal split point by the mapping function parameter;According to the electronic seal risk degree and the preset electronic seal risk degree, the electronic seal split point is offset, and the electronic seal split pattern is obtained according to the offset result;The split pattern includes a key point and several split areas, each split area corresponds to an encryption storage mechanism, and the key point is used to overlap with the electronic split point to realize electronic seal split;According to the electronic seal split point and split pattern, electronic seal fragments are dynamically retrieved and decrypted, and the electronic seal fragments after decryption are recombined to obtain electronic seal;The electronic seal is used to seal the logistics business contract, to complete the contract signing process.The electronic seal dynamic encryption storage method considering user level, electronic seal level and signature risk degree is provided, which avoids electronic seal leakage, and also provides effective identity verification mechanism, to avoid unauthorized user tampering with electronic seal.
