Description
Technical field
The present invention relates to Computer Applied Technology field, specifically a kind of system and method for online Electronic Signature.
Background technology
With the fast development of network and e-file extensive use, in the fields such as E-Government, e-commerce
The application of Electronic Signature is more and more extensive.Contrast traditional papery to affix one's seal, Electronic Signature has inexpensive, conveniently excellent
Point.
At present, Electronic Signature technology is used widely, and how to ensure the security of user's E-seal, how to be signed
Seem ever more important during chapter the problems such as the identity of verification user.The method of traditional Electronic Signature is by the way that seal information is protected
There are in the hardware such as USB KEY, when stamped signature, needs to call the hardware facilities such as USB KEY.Although this mode demonstrates user's
Identity, but user generally requires prepackage third party's plug-in unit or driving in computer and just can complete stamped signature and test the behaviour of chapter
Make.USB KEY are inconvenient to carry at the same time, are easily lost, it has not been convenient to management and granting.
It is insufficient existing for USB KEY in the prior art to solve there is an urgent need for a kind of new Electronic Signature technology based on this.
The content of the invention
The technical assignment of the present invention is to be directed to above shortcoming, there is provided a kind of system and method for online Electronic Signature.
A kind of system of online Electronic Signature, including encryption equipment, Electronic Signature server, Electronic Signature client, wherein,
Electronic Seal System is installed, Electronic Seal System and Electronic Signature client are in the separated B/ in front and back end in Electronic Signature server
S frameworks；Electronic Signature server is provided out REST api interfaces, and Electronic Signature client passes through with Electronic Signature server
REST api interfaces are interacted using JSON data；Encryption equipment is connected with Electronic Signature server, in same Intranet.
Electronic Signature server provides user management, rights management, log management and inquiry, online stamped signature, short-message verification
User identity, online making Electronic Signature function, store the information of seal and the picture of seal, the Electronic Signature server is also
By calling the interface of encryption equipment the private key needed for stamped signature can be generated for user.
The Electronic Signature client externally provides user service, and and user mutual, including by pulling the side of seal
File function after formula provides the coordinate of stamped signature to the user, preview is affixed one's seal；User carries out electronic seal by Electronic Signature client
The operation of chapter application, online Electronic Signature and the existing stamped signature of verification.
A kind of method of online Electronic Signature, based on said system, it realizes that process is,
First, online application E-seal, Electronic Signature material requested is submitted by user and is audited online, under examination ＆ verification enters after passing through
One step；
2nd, online Electronic Signature, user upload and treat stamped signature file, then will treat stamped signature file, userspersonal information and seal letter
Breath merges into data to be signed, and the seal applied in step 1 treats label data and signs, and completes online stamped signature；
3rd, online verification stamped signature, is proved to be successful then stamped signature completion.
The process of applying for electronic seal is in the step 1：User submits the seal information that needs make, seal online
Information includes seal picture, applicant's information, unit information, phone number；Auditor audits user information, if examination ＆ verification is logical
Cross, then issue E-seal for the user, if examination ＆ verification to user by not returning to application failure information.
When issuing E-seal, Electronic Signature server applies for a private key by encryption equipment for user, and by user
Personal information bound with E-seal information and the private key, which is stored in encryption equipment.
Online Electronic Signature process is in the step 2：E-file is uploaded to stamped signature server first, and is selected
The position affixed one's seal；The cell-phone number of Electronic Signature server to typing during user's application seal sends checking information, if being proved to be successful,
Then carry out, by calling encryption equipment private key to carry out computing, completing the stamped signature to e-file, if authentication failed, returning to stamped signature and lose
Lose information.
The detailed process of the step 2 is：User logs in Electronic Signature client, it would be desirable to which the file of stamped signature is uploaded to
Electronic Signature server, selection need the position of stamped signature, initiate the stamped signature operation to file；Electronic Signature server by
Family mobile phone sends verification number, determines user identity；If being proved to be successful, Electronic Signature server treats label file and carries out summary fortune
Calculate, obtain the summary data of file to be signed；Electronic Signature server is by seal information, personal certificate and the summary data of user
Merge, form data to be signed；Private key in Electronic Signature server calls encryption equipment, treats label data and signs, obtain
To the stamped signature data of file；The time stamp data of stamped signature data and server, document text to be signed are merged.
Online sign test process is in the step 3：When user initiates to test chapter operation, Electronic Signature server, which extracts, to be treated
Verify the cryptographic digest information in file, file is decrypted using the public key in user certificate, if the result of decryption and electricity
Result of the subdocument after computing of making a summary is consistent, then returns and be proved to be successful, otherwise return to authentication failed.
The detailed process of the step 3 is：File to be verified is uploaded to electronics label by user by Electronic Signature client
Chapter server；Electronic Signature server isolates stamped signature data from file, and using the public key in individual subscriber certificate to label
Chapter data are decrypted, summary data after being decrypted；The summary data of summary data and original document after decryption is calculated, if
It is identical, then it is verified；If differing, authentification failure, original document is distorted.
Compared to the prior art a kind of system and method for online Electronic Signature of the present invention, has the advantages that：
A kind of system and method for online Electronic Signature of the present invention, determines user identity by short message verification code, seal is believed
Breath is stored in the mode being managed collectively in encryption equipment, it is ensured that ensure that the peace of E-seal while stamped signature process ease for use
Entirely, the identity of user is demonstrated；The seal and digital certificate of Electronic Seal System all preserve beyond the clouds, and user need not be
Locally-installed any third party's plug-in unit can both complete application, stamped signature, the operation of verification of seal, and user can pass through online visitor
The position of the self-defined stamped signature in family end, the file after preview stamped signature improve the ease for use of system, and the private key of user is stored in encryption
In machine, it is ensured that the reliability of user data, it is highly practical, it is applied widely, it is easy to spread.
