Fig. 2 is a flowchart of a method for signing an electronic document according to 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, where the method includes:
s201, acquiring a target electronic document to be signed according to the received electronic document signing instruction.
By way of example, the target electronic document may be a contract document, such as a lease contract, a buy-sell contract, a labor contract, and the like. When a user needs to seal a certain contract document, the client can receive an electronic document seal instruction sent by the user, wherein the seal instruction comprises document information of a target electronic document to be sealed, such as a document name or a document identification, and the like, so that the target electronic document to be sealed is obtained according to the electronic document seal instruction. 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 corresponding relation of the preset electronic document picture is an incidence relation between a target electronic document and a first picture preset by a client, the client stores the target electronic document, simultaneously stores the first target picture corresponding to the target electronic document, and establishes the incidence relation between the target electronic document and the first picture as the corresponding relation of the preset electronic document picture.
S203, signature information determined by the user according to the first target picture is obtained, 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 sealing, for example, a public seal or a private seal, a financial seal or a personal seal, or the like.
The signature location information may characterize the specific location at which the user desires to cap the seal to the electronic document. For example, in the upper right corner of each page of the electronic document, or in a specific location of the electronic document where stamping is required.
The signature number information may characterize the number of seals that the customer needs to seal.
The signature sequence information may represent the signature sequence of the parties signing the contract, for example, the contract to be signed has a party a and a party b, both parties agree that the party a signs first and the party b signs later, and then the signature sequence of the party a user is before and the signature sequence of the party b user is after.
For example, the signature information may include only the target stamp information; or may include both target signature information and signature location information; or can also comprise four kinds of information, namely, target seal information, signature position information, signature number information and signature sequence information.
S204, 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.
In this step, the target electronic document may be encrypted by using a national encryption algorithm to obtain a signature value, where the national encryption algorithm is a domestic commercial encryption algorithm identified by the national institutes of ciphers, and currently three types of public algorithms SM2, SM3 and SM4 are mainly used, and are respectively an asymmetric algorithm, a hash algorithm and a symmetric algorithm, and the key length and the packet length are both 128 bits. The present disclosure is not limited to encryption algorithms.
S205, the document information, the signature information and the signature value of the target electronic document are sent to a server, so that the server performs 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 a document identification of the target electronic document. The document identification may be a document number of the target electronic document, a document name of the target electronic document, or a file check code calculated on the target electronic document by a file encryption Algorithm, where the file encryption Algorithm may be a message digest Algorithm (MESSAGE DIGEST Algorithm MD 5) or a secure hash Algorithm 2 (Secure Hash Algorithm).
Optionally, if it is confirmed that the server has stored 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 obtains the target electronic document according to the document identifier, and performs signature processing on the target electronic document; if the server is confirmed not to store the target electronic document, the target electronic document is sent to the server, so that the server performs signature processing on 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; the document information, the signature information and the signature value of the target electronic document are transmitted to a server, so that the server performs signature processing on the target electronic document. Under the condition that the client does not integrate the special processing tool for the electronic document, signature processing of the electronic document can be completed, so that development and maintenance cost of the client is reduced.
Further, after the step S205 of transmitting 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.
The second target picture is a picture corresponding to the target electronic document after finishing signature.
In this way, the second target picture corresponding to the target electronic document after the signature is completed can be displayed to the user, so that the user can confirm the correctness of the signature.
In other embodiments of the present disclosure, the first target picture may be obtained by:
first, the target electronic document is transmitted to a server.
Then, the receiving server receives the first target picture sent by the target electronic document.
In the method, the server is provided with an electronic document special 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 does not need to store the first target picture, and maintenance cost of the client is further saved.
Alternatively, the client may send the document identifier of the target electronic document to the server, so that the document identifier may be included in the subsequent message interaction between the client and the server, and the message confirming the interaction through the document identifier is signature processing of the target electronic document, so that signature processing of multiple electronic documents in parallel may be implemented. Likewise, the document identification may be a document number of the target electronic document; a document name that may be a target electronic document; the document identifier may also be a file check code calculated on the target electronic document by a file encryption Algorithm, where the file encryption Algorithm may be a message digest Algorithm (MESSAGE DIGEST Algorithm MD 5) or a secure hash Algorithm 2 (Secure Hash Algorithm).
Optionally, the client may further preset a first preset time threshold, 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 is sent in a failure mode, so that 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 client side and the server are abnormal in communication is avoided, the user waits for a long time, and signature processing experience of the user is improved.
Optionally, the client may also receive a signature failure message sent by the server, and display a prompt message to the client according to the signature failure message, so that the client checks the signature condition.
Fig. 3 is a flowchart of another electronic document signing method according to an 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, where the method includes:
s301, receiving a target electronic document sent by a client.
S302, converting the target electronic document into a first target picture.
In this step, a server-integrated electronic document specific tool may be used to process the target electronic document to obtain the first target picture.
S303, the first target picture is sent to the client so that the client can display the first target picture to a user.
S304, receiving document information, signature information and signature values of the target electronic document sent by the client.
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 a document identification of the target electronic document. The document identification may be a document number of the target electronic document, a document name of the target electronic document, or a file check code calculated on the target electronic document by a file encryption Algorithm, where the file encryption Algorithm may be a message digest Algorithm (MESSAGE DIGEST Algorithm MD 5) or a secure hash Algorithm 2 (Secure Hash Algorithm). 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 obtained by encrypting the target electronic document according to the signature private key of the user.
And S305, carrying out 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, if the verification result is successful, signing 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 completed is obtained.
If the server does not integrate the signature service function, but is configured with the signature server alone, the server may 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 completion of the signature processing.
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 displays the first target picture to a user. Receiving document information, signature information and signature values of the target electronic document sent by the client; and carrying out signature verification on the signature value according to the target electronic document to obtain a verification result, and carrying out signature processing on the target electronic document under the condition that the verification result is successful. Therefore, under the condition that the client does not integrate a special processing tool for the electronic document, signature processing of the electronic document can be completed, and development and maintenance costs of the client are reduced.
Further, in the signing process of the target electronic document, the target electronic document after the signing process is completed can be converted into a second target picture; and sending the second target picture to the client so that the client displays the second target picture to the user.
In this way, the second target picture corresponding to the target electronic document after the signature is completed can be displayed to the user, so that the user can confirm the correctness of the signature.
In addition, if the verification result is failure, a signature failure message may be sent to the client, so that the client may display prompt information to the client according to the signature failure message, so as to prompt the client to check the signature condition.
