Description

TECHNICAL FIELD

[0001] The present application relates to the field of user authentication, in particular, to an electronic signature method, system, device and storage medium based on multiple verifications. BACKGROUND

[0002] At present, since the ID card is a kind of legal certificate for proving the identity of the holder, the user's ID card information is often required to prove the user's legal identity in daily life, for example, bank account opening, ticket purchase, hospital treatment, password recovery, etc. All of these require the user's ID card information to prove the user's legal identity.

[0003] In the prior art, the user's ID card information is provided to prove the user's legal identity in various scenarios, which is generally achieved by inputting the user's ID card number information or using electronic signature equipment for personal identity information authentication. Among them, the personal identity information authentication by inputting the user's ID card number information refers to querying whether the user's identity is legal according to the user's ID card number information; the personal identity information authentication by using electronic signature equipment refers to binding multiple electronic signature equipment with user identity information, and using the digital certificate obtained when applying for electronic signature equipment to complete the personal identity information authentication to prove the user's legal identity.

[0004] However, in the electronic information environment, a person's handwritten signature can be easily tampered with and imitated by technical means, although the digital signature technology has good anti-counterfeiting authentication, data security, data integrity and non-repudiation.

[0072] S1232, according to the strokes and stroke order of each character in the text information, and combining the neural network pattern recognition of each stroke pattern in each character, the handwriting video information is split to obtain the sub-video corresponding to each stroke in the pattern information. And

[0073] S1233, sequentially combine the sub-videos based on the stroke order of the characters to obtain a sub-video sequence to generate signature-related information, but not limited thereto.

[0074] In a preferred embodiment, step S130 comprises:

[0075] S131, upload the original pattern information of the current electronic signature and the signature-related information to the first blockchain node.

[0076] S132, and generate a storage address information according to the address information in the blockchain node, but not limited thereto.

[0077] In a preferred embodiment, step S140 comprises:

[0078] S141, upload the text information corresponding to the pattern information and the storage address information to the second blockchain node, but not limited thereto.

[0079] In a preferred embodiment, further comprising:

[0080] S150, the mobile terminal collects the request of the electronic signature of the user to be authenticated.

[0081] S160, collect the electronic signature currently signed by the user to be authenticated and at least one signature related information in the signing process.

[0083] S180, according to the preset signature related information in the target account matched successfully and the signature related information of the user to be authenticated, the second authentication is carried out, but not limited to this.

[0084] In a preferred embodiment, step S180 includes at least comparing the electronic signature currently signed by the user to be authenticated with the pattern of the corresponding sequence of sub-videos in the target account and the trajectory of the newly added strokes in the sub-videos and the time information, to obtain a similarity parameter, and the authentication is carried out according to the relationship between the similarity parameter and the preset threshold.

[0085] The purpose of the present application is to provide an electronic signature method based on multiple verifications, which can confirm that the signer is himself through multiple verifications, and protect the signature information from being lost and tampered with through blockchain technology, thereby improving the security of authentication.

[0086] Figure 2 The flowchart of the implementation process of the electronic signature method based on multiple verifications of the present application. As shown in the figure, Figure 2 Firstly, the mobile terminal receives the request of the user to generate an electronic signature.

[0087] Then, the pattern information of the electronic signature currently signed by the user is collected, and at the same time, the biometric information of the user in the signing process is collected, including at least one of fingerprint, voiceprint, face, iris information, to generate signature related information. In this embodiment, the face and iris information of the user when signing are collected by the mobile terminal to generate signature related information. In the present application, the signature related information can include one of signature total time, IP address information, signature content information. In order to enhance the accuracy of authentication, the present application further collects the pattern information of the electronic signature currently signed by the user and the handwriting video information in the signing process to generate signature related information while collecting the pattern information of the electronic signature currently signed by the user and the biometric information.

[0088] The process of generating signature related information in this embodiment includes: after the user completes the electronic signature, the text information corresponding to the pattern information is identified. According to the strokes and stroke order of each character in the text information, combined with the neural network pattern recognition of each stroke pattern in each character, the handwriting video information is split to obtain the sub-video corresponding to each stroke in the pattern information (each character video represents the generation process video of a new stroke on the basis of the pattern accumulated in the previous stroke track of each character's handwriting track). The sub-videos are combined in sequence based on the stroke order of the characters to obtain a sub-video sequence to generate signature related information.

[0089] The original pattern information of the current electronic signature and the signature related information (the pattern information of the electronic signature, the signature related information generated by the biological recognition information, and the signature related information generated by the sub-video sequence) are uploaded to the first blockchain node. And generate a storage address information according to the address information in the blockchain node. The text information corresponding to the pattern information and the storage address information are uploaded to the second blockchain node, thereby realizing the entry of the user's electronic signature.

[0090] When authentication is needed, the mobile terminal collects the request of the electronic signature of the user to be authenticated. First, collect the electronic signature currently signed by the user to be authenticated and at least one signature related information in the signing process. In this embodiment, the pattern information of the user's signature and the face and iris information collected by the mobile terminal when the user signs are collected, and the sub-video sequence generated according to the strokes and stroke order of each character in the text information obtained by pattern recognition.

[0091] According to the pattern information of the electronic signature of the user to be authenticated, the corresponding target account is matched, and the first authentication is performed. After the first authentication is successful, the face and iris information of the user to be authenticated in the process of writing the electronic signature and the sub-video sequence of the text information are compared with the face and iris information of the target account and the sub-video sequence of the text information respectively (the second authentication, wherein the pattern of the corresponding sub-video in the sub-video sequence and the track and time information of the newly added stroke in the sub-video can be compared for high-precision comparison), and the similarity of each item is calculated to obtain a comprehensive similarity (in this embodiment, the similarity between the sub-video of the sub-video sequence of the text information and the sub-video in the sub-video sequence of the target account is obtained by using the existing video comparison algorithm, but it is not limited to this), if the comprehensive similarity meets the preset threshold, it is considered that the user to be authenticated matches the target account successfully. Among them, since each person's stroke order, rhythm, and pattern of individual strokes are unique, especially difficult to imitate. And even if a professional imitator can imitate the pattern of each Chinese character very well, it is still through slow writing to imitate as much as possible, so even if the high-precision imitation method is used, it will be rejected due to the very low similarity of the sub-video sequence.

[0092] The electronic signature method based on multi-verification of the present application can confirm that the signer is the person himself through multi-verification, and protect the signature information from being lost or tampered with through the blockchain technology, thereby improving the authentication security.
