In the description that follows, the terms "first," "second," and the like are used for descriptive purposes only and are not intended to indicate or imply relative importance nor order to be construed.
First, an application scenario of the present disclosure will be explained. The present disclosure can be applied to electronic document processing, particularly, signature processing of an electronic document in the PDF format. Signature processing of electronic documents is a common electronic office application, and electronic documents requiring signature processing generally adopt a PDF format. Such PDF-formatted electronic documents need to be browsed and processed by means of electronic document-specific tools, such as Acrobat Reader from Adobe corporation and some other lightweight PDF browsing tools, which are difficult to integrate into an application for signing electronic documents. In addition, some open source PDF processing programs are provided, and basic PDF interfaces are provided for integration, but the PDF document format is complex and the integration difficulty is high. In practical application, the electronic office application has various platforms, such as an Android platform, an IOS platform, a web page platform, and the like, so in order to browse and process an electronic document in a PDF format, a special tool for the electronic document needs to be integrated at a client of each platform, and adaptation and upgrade are also needed along with the upgrade of the platform, so that the development and maintenance costs of the client are high.
In order to solve the above problem, the present disclosure provides an electronic document signing method, an apparatus, a storage medium, and an electronic device, where the method includes: acquiring a target electronic document to be signed according to a received electronic document signing instruction; acquiring a first target picture corresponding to the target electronic document, and displaying the first target picture to a user; acquiring signature information determined by the user according to the first target picture; acquiring a signature private key of the user, and encrypting the target electronic document according to the signature private key to obtain a signature value of the target electronic document; and sending the document information, the signature information and the signature value of the target electronic document to a server so that the server performs signature processing on the target electronic document. Therefore, under the condition that the client side does not integrate the special processing tool for the electronic document, the signature processing of the electronic document can be completed, and the development and maintenance cost of the client side is reduced.
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings.
Fig. 1 is a schematic structural diagram of an electronic document signing system provided by an embodiment of the present disclosure, and as shown in fig. 1, the electronic document signing system may include a server 101 and a client 102, where the server 101 may integrate an electronic document special tool, such as a PDF document processing tool; the client 102 may include a plurality of clients, for example, client 1021, clients 1022, …, and client 102n, and different clients may be the same or different operating system platforms, and in this system, the client may complete the processing of the electronic document through the server without the above-mentioned dedicated tool for the electronic document, thereby implementing the signature processing of the electronic document.
Fig. 2 is a flowchart of an electronic document signing method provided by an embodiment of the present disclosure, and as shown in fig. 2, an execution subject of the method may be a client in the electronic document signing system, and the method includes:
s201, according to the received electronic document signature instruction, obtaining a target electronic document to be signed.
Illustratively, the target electronic document may be a contract document, such as a lease contract, a buy-sell contract, a labor contract, or the like. When a user needs to seal a contract document, the client may receive an electronic document sealing instruction sent by the user, where the sealing instruction includes document information of a target electronic document to be sealed, such as a document name or a document identifier, and thus, according to the electronic document sealing instruction, the target electronic document to be sealed is obtained. The target electronic document may be a PDF document.
S202, acquiring a first target picture corresponding to the target electronic document, and displaying the first target picture to a user.
In this step, a first target picture corresponding to the target electronic document may be obtained according to a preset electronic document picture correspondence. The preset electronic document picture corresponding relation is an incidence relation between a target electronic document and a first picture preset by a client, the client stores the target electronic document and the first target picture corresponding to the target electronic document at the same time, and the incidence relation between the target electronic document and the first picture is established as the preset electronic document picture corresponding relation.
S203, obtaining the signature information determined by the user according to the first target picture, wherein the signature information comprises one or more of target seal information, signature position information, signature number information and signature sequence information.
The target seal information may be a seal selected by the user for stamping, for example, public seal or private seal, financial seal or personal seal, etc.
The signature location information may characterize a user's desire to place a seal in a particular location of an electronic document. For example, at the upper right corner of each page of the electronic document, or at a particular location of the electronic document where a seal is needed.
The number of signatures information may characterize the number of stamps the customer needs to stamp.
The signature sequence information can represent the signature sequence of multiple parties signing the contract, for example, the contract to be signed has a party A and a party B, which are agreed, the party A firstly signs, and the party B later signs, so that the signature sequence of the party A user is in front of the signature sequence of the party B user.
For example, the signature information may include only target seal information; alternatively, two kinds of information, target signature information and signature position information, may be included; alternatively, four kinds of information, that is, target stamp information, signature position information, signature number information, and signature sequence information may be included.
S204, obtaining the signature private key of the user, and encrypting the target electronic document according to the signature private key to obtain the signature value of the target electronic document.
In this step, a cryptographic algorithm may be used to encrypt the target electronic document to obtain a signature value, where the cryptographic algorithm is a domestic commercial cryptographic algorithm identified by the national crypto authority, and currently, three types of algorithms, namely, public SM2, SM3, and SM4, are mainly used, which are respectively an asymmetric algorithm, a hash algorithm, and a symmetric algorithm, and the key length and the packet length are 128 bits. The present disclosure does not limit the encryption algorithm.
S205, sending the document information, the signature information and the signature value of the target electronic document to a server so that the server can perform signature processing on the target electronic document.
In this step, the document information of the target electronic document may be the target electronic document itself; or may be a document identification of the target electronic document. The document identifier may be a document number of the target electronic document, a document name of the target electronic document, or a file check code calculated by a file encryption Algorithm on the target electronic document, where the file encryption Algorithm may be a Message Digest Algorithm (Message Digest Algorithm MD5) or a Secure Hash Algorithm 2(Secure Hash Algorithm 2).
Optionally, if it is determined that the server already stores the target electronic document, the document information is a document identifier of the target electronic document, and the document identifier is sent to the server, so that the server can obtain the target electronic document according to the document identifier and perform signature processing on the target electronic document; and if the server is confirmed not to store the target electronic document, sending the target electronic document to the server so that the server can sign the target electronic document.
By adopting the method, the target electronic document to be signed is obtained according to the received electronic document signing instruction; acquiring a first target picture corresponding to the target electronic document, and displaying the first target picture to a user; acquiring signature information determined by the user according to the first target picture; acquiring a signature private key of the user, and encrypting the target electronic document according to the signature private key to obtain a signature value of the target electronic document; and sending the document information, the signature information and the signature value of the target electronic document to a server so that the server performs signature processing on the target electronic document. Under the condition that the client is not integrated with the special processing tool for the electronic document, the signature processing of the electronic document can be completed, so that the development and maintenance cost of the client is reduced.
Further, after the step S205 sends the user signature information and the signature value to the server, the method may further include:
and after the server finishes signing the target electronic document, receiving a second target picture sent by the server and displaying the second target picture.
And the second target picture is a picture corresponding to the target electronic document after the signature is finished.
Therefore, the second target picture corresponding to the signed target electronic document can be displayed to the user through the method, so that the user can confirm the correctness of the signature.
In some other embodiments of the present disclosure, the first target picture may be obtained by:
first, the target electronic document is sent to a server.
Then, a first target picture sent by the server according to the target electronic document is received.
In this mode, the server has an electronic document specific tool, and can convert the received target electronic document into a first target picture and then send the first target picture to the client.
By the method, the client side does not need to store the first target picture, and the maintenance cost of the client side is further saved.
Optionally, the client may also send the document identifier of the target electronic document to the server, so that subsequent message interactions between the client and the server may all include the document identifier, and it is determined through the document identifier that the interactive message is a signature process for the target electronic document, thereby implementing a signature process for multiple electronic documents in parallel. Likewise, the document identification may be a document number of the target electronic document; may be the document name of the target electronic document; the document identifier may also be a file check code calculated by a file encryption Algorithm for the target electronic document, where the file encryption Algorithm may be a Message Digest Algorithm (Message Digest Algorithm MD5) or a Secure Hash Algorithm 2(Secure Hash Algorithm 2).
Optionally, the client may further preset a first preset time threshold, and after the target electronic document is sent to the server, if the first target picture sent by the server is not received within the first preset time threshold, it is determined that the electronic document fails to be sent, so that the signature failure of the electronic document is determined, and signature failure information of the electronic document may be displayed to the user. Therefore, the situation that the user waits for a long time under the condition that the communication between the client and the server is abnormal is avoided, and the signature processing experience of the user is increased.
Optionally, the client may also receive a signature failure message sent by the server, and display prompt information to the client according to the signature failure message, so that the client can check the signature condition.
Fig. 3 is a flowchart of another electronic document signing method provided by the embodiment of the present disclosure, and as shown in fig. 3, an execution subject of the method may be a server in the electronic document signing system, and the method includes:
s301, receiving the target electronic document sent by the client.
S302, converting the target electronic document into a first target picture.
In this step, the target electronic document may be processed using a server-integrated electronic document specific tool to obtain a first target picture.
S303, sending the first target picture to the client, so that the client displays the first target picture to a user.
S304, receiving the document information, the signature information and the signature value of the target electronic document sent by the client.
And the signature information and the signature value are generated by the client according to the operation of the user on the first target picture.
Likewise, the document information of the target electronic document may be the target electronic document itself; or may be a document identification of the target electronic document. The document identifier may be a document number of the target electronic document, a document name of the target electronic document, or a file check code calculated by a file encryption Algorithm for the target electronic document, where the file encryption Algorithm may be a Message Digest Algorithm (Message Digest Algorithm MD5), or a Secure Hash Algorithm 2(Secure Hash Algorithm 2). In the case where the server stores the target electronic document, the target electronic document may be acquired by the document identification.
The signature information may include one or more of target seal information, signature position information, number of signatures information, and signature sequence information.
The signature value may be a signature value of the target electronic document obtained by encrypting the target electronic document according to a signature private key of the user.
S305, performing signature verification on the signature value according to the target electronic document to obtain a verification result.
In this step, the server may decrypt the signature value using the public key, and if the decryption is successful, the verification result is successful; if the decryption fails, the verification result is failure.
And S306, under the condition that the verification result is successful, performing signature processing on the target electronic document.
If the server integrates the signature service function, the signature processing is directly carried out on the target electronic document according to the signature information, and the target electronic document after the signature processing is finished is obtained.
If the server does not integrate the signature service function but is separately configured with a signature server, the server can communicate with the signature server, send the signature information to the signature server, complete the signature processing by the signature server, and return the target electronic document after the signature processing is completed.
By adopting the method, the target electronic document sent by the client is received; converting the target electronic document into a first target picture; and sending the first target picture to the client so that the client presents the first target picture to a user. Receiving document information, signature information and a signature value of the target electronic document sent by the client; and performing signature verification on the signature value according to the target electronic document to obtain a verification result, and performing signature processing on the target electronic document under the condition that the verification result is successful. Therefore, under the condition that the client side is not integrated with a special processing tool for the electronic document, the signature processing of the electronic document can be completed, and the development and maintenance cost of the client side is reduced.
Furthermore, when the target electronic document is subjected to signature processing, the target electronic document after the signature processing can be converted into a second target picture; and sending the second target picture to the client so that the client can display the second target picture to the user.
Therefore, the second target picture corresponding to the target electronic document after the signature is completed can be displayed to the user through the method, so that the user can confirm the correctness of the signature.
In addition, when the verification result is failure, a signature failure message can be sent to the client, so that the client can display prompt information to the client according to the signature failure message to prompt the client to check the signature condition.
