Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The method for displaying the page electronic signature can be applied to the application environment shown in fig. 1, wherein computer equipment or terminal equipment is communicated with a server through a network. The computer device or the terminal device may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices. The server may be implemented as a stand-alone server or as a server cluster consisting of a plurality of servers.

In an embodiment, as shown in fig. 2, a method for displaying an electronic signature of a page is provided, which is described by taking the method applied to the client in fig. 1 as an example, and includes the following steps:

s1: and receiving a confirmation instruction of a user, and sending a calling instruction to a background interface, wherein the calling instruction is used for informing the background interface to call the file content to be synthesized.

Specifically, the text browsed on the page prompts the user to sign a file in an electronic signature mode, and prompts the user to confirm the text content by clicking the check before the text is clicked. When the user clicks the text prompt information, the user is considered to agree to use the electronic signature mode to confirm the file, at this time, the client side sends a call instruction to a background interface of the server side, the call instruction is used for acquiring file content needing to be synthesized from the background interface, and the file content is the file which needs to be combined with the electronic signature and is displayed on a page of the user.

Specifically, the document contents may include a personal credit card, a policy, a contract for policy, and a policy confirmation page, while embedding personal information of the user and the like in a blank document template.

S2: and inputting the user identification into the electronic signature generation control.

Specifically, the electronic signature generation control is deployed at the client and the server at the same time, and the electronic signature generation control deployed at the server is used for responding to various management requests of the management client, and comprises a management and setting request of a system administrator on the electronic signature service, an audit request of an auditor on a log, an update information request of a user and the like.

The electronic signature generation control deployed on the client is used for performing operations such as database configuration, user management, certificate configuration, electronic signature service management, signature audit, signature management, submission of seal encryption data, information updating and the like, and management of the life cycle of the seal in the system is achieved. Specifically, the method can comprise the steps of authenticating the identity of a requester of the electronic signature, providing a timestamp service and a verification service for a signature request, and providing a root certificate and other services for a client. Further, the electronic signature generation control generates signature data corresponding to the user identifier on the client through the user identifier for the steps described later.

S3: and generating the user identification into signature encryption data through the electronic signature generation control.

Specifically, the electronic signature generation control deployed at the client generates signature encryption data corresponding to the user identifier of the user to ensure the integrity, tamper resistance and non-repudiation of the application document, and the electronic signature generation control deployed at the background interface can receive and read the user identifier of the user in the signature encryption data and can achieve the same display effect as paper stamping or signature by processing the complex image of the electronic seal.

Further, the implementation of the electronic signature technology requires the use of an asymmetric encryption (RSA algorithm), which means that the user has two keys, one is a public key and the other is a private key, the public key is public and can be used by anyone, the private key is secret and can be used by only the user, and the public key and the private key are in a corresponding relationship. The user can encrypt information by using the public key of the other party and transmit the information to the other party, and the other party uses the private key of the other party to unlock the ciphertext. The public and private keys are mutually decrypted and absolutely no third party can be inserted.

In an alternative embodiment, the signature encryption data may also be stored in the blockchain. Specifically, the corresponding digest information is obtained based on the signature encrypted data, and specifically, the digest information is obtained by hashing the signature encrypted data, for example, using the sha256s algorithm. Uploading summary information to the blockchain can ensure the safety and the fair transparency of the user. The user device may download the digest information from the blockchain to verify that the signed encrypted data has been tampered with. The blockchain referred to in this example is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, and the like. A block chain (Blockchain), which is essentially a decentralized database, is a series of data blocks associated by using a cryptographic method, and each data block contains a batch of information with digital signatures for verifying the validity (anti-counterfeiting) of the information and generating a next block. Through the blockchain, a user or a third-party supervision mechanism can confirm whether the underlying data of a certain signature service is tampered or not so as to further enhance the effectiveness of electronic signature.

In an alternative embodiment, the signed encrypted data may also be used in conjunction with a digital certificate. Specifically, when a user uses an APP or logs in a service website for digital signature, a data certificate of an interface connected with the APP or the website is detected to determine whether the interface is a malicious phishing website or the like, and if the certificate of the background interface does not match a preset certificate, a warning can be sent to the user, and the connection is disconnected, so that the connection security is further ensured.

And S4, sending the signature encryption data to the background interface for the background interface to generate an electronic signature through the signature encryption data, or for the background interface to acquire the electronic signature corresponding to the user identifier.

Specifically, the electronic signature generation control generates signature encryption data corresponding to the user identifier of the user and transmits the signature encryption data to the background interface, and the background interface can generate or acquire the electronic signature according to the signature encryption data. As described above, the electronic signature generation control is also deployed in the background interface, and can generate or acquire the electronic signature through the received signature encryption data in the background interface.

Further, the electronic signature generation control deployed at the server may further include a seal making tool, and the seal making tool is used for making a seal and saving the seal as a picture file, so that the seal is conveniently imported into the intelligent password key or the database in the future.

S5: identifying whether the file content contains preset keywords or not, if so, desensitizing the corresponding keywords in the file content and the values of the keywords to obtain desensitized file content;

when the preset keywords are contained in the file content, synthesizing the desensitized file content and the electronic signature to obtain a synthesized page;

and when the preset keywords are not contained in the file content, synthesizing the file content and the electronic signature to obtain a synthesized page.

In order to further protect the personal information security and privacy of the user, under some specific application scenarios, keywords in the file content need to be desensitized, where the keywords include personal information such as contract number, user name, telephone number, and address, and a service identification code corresponding to a confirmation instruction; the value of the keyword includes a value corresponding to the keyword, for example, the keyword is "telephone number", and the value of the keyword is 13512345678. And finally, synthesizing the desensitized file content and the electronic signature to obtain a desensitized synthesized page, and presenting the desensitized synthesized page to a user.

Further, the document content called at step S1 is synthesized with the electronic signature generated/obtained through the above-described steps, resulting in a synthesized page. The composite page is a page containing the image representing the electronic signature and the document contents of the personal credit investigation authorization, insurance policy, insurance contract, insurance policy confirmation page, etc., and as mentioned above, the page may be desensitized or non-desensitized and is displayed according to the needs and settings of the customer. Ideally, the composite page generated should be consistent with the paper document, i.e., it can be printed directly for use as a paper document.

S6: the composite page is transmitted to a graphical interface and the composite page is presented in the graphical interface.

Specifically, the composite page is displayed in an APP on the client or a graphical interface in a webpage, and is displayed to the client for confirmation, for example, whether the file content, personal information, signature/seal position, and the like are correct or not is confirmed. Ideally, the composite page generated should be consistent with the paper document, i.e., it can be printed directly for use as a paper document.

According to the method for displaying the page electronic signature in the embodiment of the invention, when a user clicks a confirmation button, an electronic signature generation control deployed on a client generates encrypted data by using a user identifier, and simultaneously sends a call instruction for calling file content, and then an electronic signature generation control deployed on a background interface generates or acquires an electronic signature in real time through the encrypted data; and because the file and the electronic signature are combined and transmitted in an encrypted manner, the file and the electronic signature are safer.

In a specific embodiment, the call instruction includes the user identifier, and the call instruction further includes notifying the background interface to call the file content corresponding to the user identifier according to the user identifier in the call instruction.

In particular, in a service provided specifically for a certain user or group of users (e.g., customers with a high payment amount, VIP users, etc.), the file content may be different from the general file content (e.g., format contract) or additional file content may be required. Therefore, in step S1, after sending the call instruction including the user identifier to the background interface, the background interface may determine whether the user is a specific user or is in a specific user group according to the user identifier in the call instruction, and if so, the background interface calls the specific file content corresponding to the user.

In a specific embodiment, before the step of sending the call instruction to the background interface as shown in fig. 3, the method further includes the following steps:

detecting whether a user identifier is stored in a memory;

if the user identification is stored in the memory, acquiring the user identification from the memory;

and if the user identifier is not stored in the memory, acquiring the user identifier from the background interface, or prompting the user to input the user identifier.

Specifically, in some application scenarios, the client needs to confirm whether its own memory stores the user identifier, so as to facilitate subsequent steps. In some specific scenarios, for example, a user may not log in a server to view contents of files and also wants to view a page containing an electronic signature, at this time, the client needs to remind the user to input a user identifier of the client, or obtain the user identifier of the user from the server when logging in the server (i.e., a background interface).

In an optional embodiment, the user identifier includes a name of the user, a mobile phone number of the user, an identity number of the user, a user ID, and/or a service identification code corresponding to the confirmation instruction.

Specifically, the user identifier is used to identify user information, which may be a name of the user, a mobile phone number of the user, and an identification number of the user, and may be used as long as the user identifier can identify which user is specific. In an alternative embodiment, the service identification code corresponding to the confirmation instruction may also be used as the user identifier, for example, the order number of the order.

In a specific embodiment, before the step of sending the signature encryption data to the background interface, the method further includes:

s201: calculating the signature encrypted data through a Hash algorithm to generate a 128-bit Hash value;

s202: and storing the 128-bit hash value as a message digest to the header of the signature encryption data, wherein the message digest is used as a unique identification of the service.

Specifically, the message digest uses a hash algorithm to operate on any information to be transmitted, so as to generate a 128-bit message digest (hash value), and information with different contents must generate different message digests, which are the identifiers of the service. The message digest may be stored in the header of the signed encrypted data for prompt identification of the signed encrypted data by the background interface. In a specific embodiment, the electronic signature is a picture including the user identifier generated according to the signature encryption data, and the picture includes a handwritten signature, a stamp, a barcode and/or a two-dimensional code.

Specifically, the electronic signature may be a signature, a stamp, a barcode and/or a two-dimensional code set in advance by the user, and the user may determine, according to the preference of the user, a form of an image generated according to the signature encryption data, for example, a signature with a personalized font and a stamp style selected according to the preference of the user, and optionally, the stamp style may also be combined with the signature with the personalized font. Optionally, in order to further improve the security and the repentability of the signature, the picture may further include a barcode and/or a two-dimensional code, including a timestamp and verification information.

In a specific embodiment, the electronic signature includes a custom picture that the user uploaded to the background interface in advance.

Specifically, a user can upload a self-defined picture to a background interface in advance, when the background interface receives signature encryption data, firstly, whether the user corresponding to the signature encryption data uploads the self-defined picture to the background interface in advance is judged, and if yes, the self-defined picture uploaded by the user in advance is directly acquired as an electronic signature; and if not, generating the electronic signature by using the electronic signature generation control deployed on the background interface. Further, when the user is a legal person, the picture may be a official seal scan or an electronic official seal of the legal person company.

In some optional embodiments, the electronic signature generation control may embed an electronic watermark containing signature encryption data and/or a two-dimensional code in the customized picture to improve the security and the repentability of the signature.

In a specific embodiment, as shown in fig. 4, the synthesizing the document content and the electronic signature to obtain a synthesized page includes:

s501: copying the file content as a copy of the file content;

s502: identifying whether the file content copy comprises a contract number, the personal information of the user and/or a service identification code corresponding to the confirmation instruction, if so, desensitizing the contract number, the personal information of the user and/or the service identification code corresponding to the confirmation instruction to obtain desensitized file content;

s503, the desensitization file content and the electronic signature are synthesized to obtain a desensitization synthesis page;

the step of transferring the composite page to a graphical interface and presenting the composite page in the graphical interface further comprises:

s601, the desensitization composite page is transmitted to a graphical interface, and the desensitization composite page is displayed in the graphical interface.

In order to further protect the security and privacy of personal information of a user, in some specific application scenarios, it is necessary to desensitize the file information in the file content, where the keywords include personal information such as contract number, user name, telephone number, address, and the like, and a service identification code corresponding to a confirmation instruction, and a number or code following the keyword needs to be identified. Specifically, the file content containing the file information is copied to a copy of the file content, and if the copy is identified to have a keyword, the file information in the copy of the file content is desensitized, for example, if a "mobile phone number" is detected, 13512345678 behind the mobile phone number may be desensitized to 135 × 5678; for another example, the address information Shenzhen Shentian region Yitian road 5033 can be desensitized to Shenzhen Shentian region Yitian road 9. Desensitization is significant in that part of the information is retained for verification by the user while ensuring that the privacy of the user is not revealed. And finally, synthesizing the desensitized file content and the electronic signature to obtain a desensitized synthesized page, and presenting the desensitized synthesized page to a user.

It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
