In embodiments of the present invention, when affixing one's seal by E-seal relevant information and printed text digitized signature record with the label corresponding to stamping source file, wherein this label presets to arrange, with a segment information of stamping source file logic binding, it both can be set to and corresponding file is stored in same physical file, also can independently leave in other file or in database.By using label to carry out the affix one's seal operation of managing electronic seal to file, any amendment can not be shone into stamping source file.
Fig. 1 is that in the embodiment of the present invention, E-seal is affixed one's seal the process flow diagram of method.As shown in Figure 1, the method comprises the following steps:
Step 101: adopt preset algorithm to calculate the digest value of stamping source file.
Step 102: adopt preset algorithm to calculate the digest value of E-seal relevant information.Wherein E-seal relevant information comprises seal information and information of affixing one's seal.Seal information comprises E-seal view data, the digital certificate of E-seal, the digital signature information of E-seal, E-seal metadata.Wherein E-seal metadata can comprise again E-seal issuer certificate, E-seal issues the time, the combination of one or more in E-seal owner information, the E-seal term of validity, E-seal title.The information of affixing one's seal comprises affix one's seal positional information and/or temporal information of affixing one's seal, and positional information of affixing one's seal comprises seal lid page number hereof and/or seal covers the position in file page.As when file only has one page, positional information of affixing one's seal can only include seal and cover the positional information in file page, if when document exceedes one page, positional information of affixing one's seal can comprise chapter lid page number hereof and seal covers the position in file page.And for example when without the need to paying close attention to positional information that seal covers at file page, positional information of affixing one's seal only can comprise chapter lid page number information hereof.
Step 103: digital signature is carried out to the digest value of stamping source file and the digest value of E-seal relevant information, obtains printed text data signature.
Use the digest value of private key to the digest value of stamping source file and E-seal relevant information in E-seal digital certificate to do digital signature altogether, obtain printed text digital signature.
Step 104: E-seal relevant information and printed text data signature are all recorded in the label.
Here the step in step 104, E-seal relevant information being recorded in label can perform separately, namely this step and step 101 to step 103 do not have strict sequencing, as this step can be carried out before step 101, namely first by E-seal relevant information record in the label, order performs step 101 to step 103 and obtains printed text data signature again, in the label by printed text data signature record finally.
Here identical preset algorithm can be adopted in step 101 and step 102, also different preset algorithm can be adopted.No matter adopt identical preset algorithm or different preset algorithm, the algorithm record preferably step 101 and step 102 adopted respectively in the label, uses for when testing chapter.If certainly with test Zhang Fang and have special agreement, can not by the algorithm record to adopt in the label.Here preset algorithm can be MD(message-digest algorithm, md5-challenge) 5, SHA(secure hashalgorithm, Secure Hash Algorithm) 256 and SHA-1 etc.
Through above-mentioned steps, in the label corresponding to stamping source file, following information can be comprised: file identification, file attribute, seal attribute, Authorization Attributes and file operation daily record.
Wherein, file identification unique identification stamping source file.The relevant information such as filename, file size of include file in file attribute.Authorization Attributes is for limiting the operating right to file, and as specified, which kind of action type of which kind of user to file has operating right etc.File operation daily record is for recording one or more information of affixing one's seal to file, and each file operation packets of information is containing action type, operator and running time, and wherein action type can be affix one's seal, test chapter or read seal information.The attribute of one or more seal is comprised in seal attribute.The attribute of a seal can comprise seal information, information of affixing one's seal and printed text digital signature information.
The above E-seal method of affixing one's seal can be performed by application software, namely performs step 101 to the method for affixing one's seal of step 104 by application software, and by last E-seal relevant information and printed text digitized signature record in label.Another kind of more excellent mode is the method for affixing one's seal specifically being performed above-mentioned steps 101 to step 104 by secure file service middleware, but leaves the standard interface of correspondence for application software, calls, thus application software be separated with operation of affixing one's seal for various application software.The advantage of this mode to allow application software be absorbed in application problem, and secure file service middleware is absorbed in operation of affixing one's seal.

The interface function parameter of interface of wherein affixing one's seal comprises secure ID, stamping source file name, file destination name of affixing one's seal, information of affixing one's seal and seal information.Function return value then returns error message for success or not information of affixing one's seal, failure of affixing one's seal simultaneously.Wherein secure ID is for shifting to an earlier date registration in secure file service middleware 202, legal user ID.When validated user calls secure file service middleware 202 by application software, secure ID is the mark of this validated user.When label file and stamping source file are stored in same physical file, this file destination of affixing one's seal refers in the physical file comprising label file and stamping source file, and when label file is independent of stamping source file, this file destination of affixing one's seal refers to label file.
When there is not the label file corresponding with stamping source file before, secure file service middleware 202 generates has the label file that user specifies file destination name of affixing one's seal, and the information after affixing one's seal is recorded in the label file of generation.If there is the file destination name of affixing one's seal that user specifies before, then the information after affixing one's seal directly is recorded in the label file of generation by secure file service middleware 202.
The interface function parameter testing chapter interface comprises secure ID, file destination name of affixing one's seal and seal sequence number to be verified (such as identify seal sequence number to be verified with natural number, represent with "-1 " seal that checking is all).Function return value is the checking situation of the seal that input parameter is specified, and comprises the information whether information of each seal and each seal are verified.
The interface function parameter obtaining seal information interface comprises secure ID, file destination name of affixing one's seal and seal sequence number to be obtained (such as identify seal sequence number to be verified with natural number, represent with "-1 " seal information that acquisition is all).The information of seal that function return value is seal quantity and specifies.
When application software 201 calls above interface function, can specify corresponding function parameter for these interface functions, secure file service middleware 202 performs corresponding operation according to the interface function parameter of correspondence.
No matter perform aforesaid operations by application software or secure file middleware, application software or secure file middleware all need to possess the operating right to label, therefore after the binding completing label and stamping source file, utilize the signature private key of application software or secure file middleware to calculate all the elements in label except label integrity signature make a summary and sign, this signature result is placed in label as label integrity signature, perform before above-mentioned document function information is recorded in label in application software or secure file middleware, utilize the public signature key of application software or secure file middleware to verify that application software or secure file middleware possess the functipnal capability to label.Detailed process comprises: first use the public signature key of application software or secure file middleware to verify label integrity signature, if be verified, then label is complete credible, then digest calculations is carried out to file, relatively digest calculations result and the interior document recorded of label body, as identical, then show that application software or secure file middleware possess the functipnal capability to label.
In addition under many circumstances, user wishes to affix one's seal, signs, reads, a series of document operation such as printing can unify organically to be managed.For this reason can by signing, read, the sequence of operations information such as printing all records in the label, carrys out all document functions of unified management by label.Such label just unified management can affix one's seal operation with other to the operation of file.Namely label can the attribute of storage file, the operator of defined file and authority the operation vestige of record to file.
Label corresponding to such stamping source file can comprise following information: file identification, file attribute, cryptographic attributes, seal attribute, Authorization Attributes and file operation daily record.
Wherein, cryptographic attributes comprises the enciphered message to file.Action type now can also be sign, read or print etc. in addition.
Equally can also by the function further genralrlization of secure file service middleware to signing, reading or print etc. in a series of document function, namely the operation to this kind of safe operation has been carried out by secure file service middleware, but for application software leaves the safe operating standards interface of various correspondence, call for various application software, thus application software is separated with safe operation.Such security firm just can be absorbed in safety applications details, and application vendor is absorbed in application flow.
Corresponding to the method for affixing one's seal of the E-seal that the embodiment of the present invention provides, the embodiment of the present invention also proposed a kind of seal apparatus of E-seal, in the simplest situation, can comprise: the first module, for arranging a label bound with stamping source file; Second module, for when affixing one's seal by E-seal relevant information and printed text digitized signature record in the label that stamping source file is corresponding.Seal apparatus can further include the 3rd module, for providing corresponding interface of affixing one's seal, calls for other application software, and when described interface of affixing one's seal is called, performs operation of affixing one's seal.Certain seal apparatus can further include four module, for when carrying out other document function, by other document function information records in the label, by label unified management.Seal apparatus can further include the 5th module, for providing other corresponding document function interface for application software, calls for application software.As can be seen from the above description, when seal apparatus only comprises the first module and the second module, or when comprising the first module, the second module and four module, an application software can in fact be thought.When seal apparatus comprises the first module, the second module and the 3rd module, or when the first module, the second module, the 3rd module, four module and the 5th module, in fact it can think secure file service middleware.
