In addition, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, it will be understood by those skilled in the art that the aspects may be practiced without these specific details.

At present, with the continuous development and standardization of businesses, signature information is needed to confirm validity when business is handled, but traditional signature verification needs to be mailed or sent by personnel, the disadvantages that original pure paper signatures or documents need to be mailed and are not easy to store are gradually reflected, manual contract comparison and other operations are needed when the signatures are verified, and errors are easy to occur. The embodiment of the disclosure provides a method for electronic signature and signature verification of a mobile terminal, which can be applied to a signature verification process in a scene of network payment application or electronic contract signing.

Referring to fig. 1, a flow chart of a method for performing electronic signature and signature verification on a mobile terminal according to an embodiment of the present disclosure is shown. As shown in fig. 1, the method mainly comprises the following steps:

s101, confirming identity information of a target person and corresponding target operation;

the electronic device may be provided with an operation confirmation module, or may be externally connected with an operation confirmation device, where the operation confirmation module and the operation confirmation device are configured to determine a target operation corresponding to the target person according to the action of the target person, and of course, a plurality of ports may be provided, where each port corresponds to a different target operation.

For example, if the method for verifying electronic signature and signature by a mobile terminal is applied to a network payment application scenario, after the identity information of the target person is confirmed, the target operation of the target person may be confirmed, and the target operation may be any one of a pre-payment application operation, a payment for delivery application operation, a delivery application operation, or a warranty payment. Specifically, the step of confirming the identity information of the target person may be to confirm the real-name information of the target person, obtain the authorization of the unit corresponding to the target person, and then confirm the private key held by the target person, thereby completing the verification of the person identity information.

S102, acquiring a verification image input by the target person, wherein the verification image comprises at least one signature image;

the electronic device may be equipped with an image acquisition module, or may be externally connected to an image acquisition apparatus, and the image acquisition module and the image acquisition apparatus may acquire the verification image input by the target person through data transmission, scanning, or the like. After the verification image is acquired, the verification image can be directly sent to a processor for analysis and processing operation, of course, the acquired verification image can also be stored in a preset storage space, and when the verification image needs to be verified and analyzed, the verification image is taken out from the storage space.

In a specific implementation, the verification image is generally an image such as a contract document, the verification image includes at least one signature image, and the signature image is verified in a subsequent verification process.

S103, selecting a verification condition corresponding to the target operation;

after the target operation corresponding to the target person is confirmed, different verification conditions corresponding to different operations are considered, for example, when a prepayment application operation is performed, corresponding verification conditions can be requirements for adding a financial signature and a company contract signature.

S104, judging whether the verification image meets the verification condition;

in specific implementation, the verification image is generally an image such as a contract document, the verification image includes at least one signature image, and all signature images in the verification image are compared with the verification conditions, so as to determine the next operation flow.

If the verification image meets the verification condition, executing step S105 to execute the target operation;

when all the signature images in the verification image are compared with the verification conditions, if all the signature images in the verification image are in accordance with the verification conditions, the target operation is executed, and the verification efficiency is improved when the unified verification is carried out.

If the verification image does not meet the verification condition, step S106 is executed to prohibit the target operation from being executed.

When all the signature images in the verification image are compared with the verification condition, if all the signature images in the verification image do not accord with the verification condition, or any signature image in the verification image does not accord with the verification condition, the target operation is forbidden to be executed, and the verification safety is improved.

In the embodiment of the disclosure, the corresponding verification condition is selected according to the target operation selected by the target person, and whether the target operation is executed or not is determined after the acquired signature image is compared with the verification condition, so that the efficiency and the safety of the electronic signature and signature verification method of the mobile terminal are improved.

On the basis of the foregoing embodiment, as shown in fig. 2, before the identity information of the target person and the corresponding target operation are confirmed in step S101, the method further includes:

s201, obtaining verification conditions corresponding to all the target operations;

in specific implementation, the verification condition corresponding to each target operation may be set according to an actual situation, the electronic device may obtain all the verification conditions corresponding to the target operations in advance and store data, and when the verification condition needs to be selected according to the target operation corresponding to the action of the target person, the electronic device may perform corresponding selection according to the stored data.

S202, inputting a reference image group corresponding to each verification condition, wherein the reference image group at least comprises a target image for judging whether the verification image meets the verification condition.

For example, when a prepaid application operation is performed, the approval verification requires the addition of a financial signature and a company contract signature, or requires an additional financial signature, and the corresponding target images such as a financial signature and a company contract signature, etc. may be entered according to the verification conditions and all of the target images may be taken as the reference image group.

Further, the step S104 of determining whether the verification image meets the verification condition includes:

extracting all the signature images in the verification image;

in specific implementation, a text part and a signature part in the verification image can be identified through an algorithm, then an image of the signature part is extracted, and the image of the signature part can be divided into a plurality of signature images according to the number of signatures considering that the verification image may have a plurality of signature images.

and comparing all the signature images with all the target images in the reference image group so as to determine the next operation flow.

For example, each signature image may be matched with all the target images in the reference image group, or keyword information in all the signature images and keyword information in all the target images may be extracted first, and then matching is performed according to the keyword information to obtain a matching result.

when all the signature images in the verification image are compared with all the target images in the reference image group, if all the signature images in the verification image are matched with all the target images in the reference image group, the verification image is judged to accord with the verification condition, and the verification efficiency is improved when unified verification is carried out.

If all the signature images in the verification image are matched with all the target images in the reference image group, or any signature image in all the signature images in the verification image cannot be matched with all the target images in the reference image group, the verification image is judged to accord with the verification condition, and the safety of verification is improved

On the basis of the above embodiment, as shown in fig. 3, after the step of entering the reference image group corresponding to each of the verification conditions, the method further includes:

s301, encrypting all the target images in the reference image group through a preset algorithm;

optionally, the preset algorithm is an elliptic curve public key cryptographic algorithm.

Further, in step S301, encrypting all the target images in the reference image group by using a preset algorithm includes:

converting the digest value into a key.

In consideration of the risk that data may be intercepted and stolen by a third party when the target image is transmitted, the target image can be encrypted for transmission and storage when being transmitted. The elliptic curve public key cryptographic algorithm can be used for encryption, the digest values of the file streams corresponding to all the target images are calculated firstly, and then the digest values are converted into keys. Of course, an RSA encryption algorithm or other encryption algorithms may be used as the preset algorithm.

S302, storing the encrypted reference image group to a preset space.

In specific implementation, the encrypted reference image group may be stored in a database of the processor of the backend server, so that the reference image group corresponding to the verification condition can be conveniently called when the verification image is compared subsequently. Of course, when the reference image group is called, the reference image group can be decrypted through the preset algorithm to obtain an original image.
