Description

A kind of E-seal

Technical field: the utility model relates to and is applied to E-Government, ecommerce and other occasion and has to electronic text file the method for designing of a kind of E-seal of the signature that electronic graphics file and paper document carry out and device.

Technical background: the use seal is confirmed paper document and is signed, is that China learns and pass on one of cultural tradition for many years.Traditional seal has following function and feature: 1, status blip facility: the expression seal owner's that the figure of seal or literal are clear and definite status; group, organize the pictograph of seal to put on record, have " evidence " and render a service and be protected by the law through legal organs.2, seal has uniqueness characteristic: this is that the implication of the legal effect of seal determines that each piece seal all has the further feature of its distinctive geometric configuration or setting, and can not copied simply.The special pattern with personal characteristics of some, for example the signature of fingerprint has the legal effect identical with seal under identifiable situation.3, directly recognize performance: the literal of signature, symbol and seal are visual figure and literal and are recognized by corresponding crowd.4, confirm performance: the file that file is confirmed by seal is considered to acquire full legal force and the undeniable evidence that maybe can not change.5, indivedual job operation features of making: up at present, making stamp all can not use to be produced in batches but the manual mode of scribing one by one, to reach the purpose of its uniqueness.The making stamp person of organization unit of organ must be by the legal organs mandate, and any unwarranted individual, unit scribe this type of seal and will violate the law.

The normally used seal of China has also passed on the material culture and the cultural connotations such as collection, appreciation that are comprised of art such as the fine arts in the Chinese culture, calligraphy, drawing, seal cutting and making seal except above-mentioned legal connotation.

Along with science and technology development, computer technology, electronics memory technology and network technology have caused the generation of e-file.E-file is to produce text, figure by means of computer technology, and the electronics memory technology is put down in writing, and is a kind of novel document form that medium transmits by means of electric network.

E-file is that a kind of and tangible media files has different in essence files in generation, existence, transmission in form.E-file utilizes the input media on the computing machine and includes the program software control generation down of standard letter, both may be displayed on the computer screen, can be converted to paper document by printing device again.Any people who is familiar with program software can utilize standard letter or duplication technology layout, produce the e-file of standard, standard on different computing machines; The e-file that duplicates, revised can leave no trace; E-file can leave in the electronic memory, and jumbo electronic memory is deposited considerable file; E-file can be by means of characteristics such as electric network high-speed transfer.The e-file layout, make robotization, storage with no paper, transmit at a high speed turn to growing ecommerce, E-Government lays the first stone.

The affirmation of e-file signature and tangible media files are had sizable different, this is to be the reason of " visual and untouchable " because of e-file.For example utilize e-file to pass through a contract for future delivery of networks sign, will have following problem: 1, do not have " physical evidence "; 2, can not divide original paper or duplicate only according to e-file, authenticity that can not positive file producer identity; 3, can not whether be distorted from file identification content itself; 4, intercepted and captured by other people in the transmittance process and distort or give away secrets etc.; 5, contract one side's malice is denied.Produced the safety issue that exists in file generation in the affirmation of e-file and signature and ecommerce, the E-Government, storage, the transmittance process owing to these reasons.

At present, some countries solve ecommerce in the world, the electronic political administration and security problem has adopted the method that electric network safety certification mechanism is set, the user is in digital certificate institute registration electronic security(ELSEC) certificate and digital signature, and information and file published on the electric network server of certification authority, by the webserver of digital certificate mechanism is inquired about, can confirm that file sender's identity, inquiry are identified file.So-called electronic security(ELSEC) certificate and digital signature are actually the password in certification authority's registration, are called public keys and private key, have certain functional relation between them.Public keys is disclosed, it offers the user who needs, the file that utilizes private key to carry out the encryption that cryptographic calculation obtains can be understood by public keys, and relevant information and other information that needs of key holder identity, file, standing and certification authority can be on the webserver of certification authority, obtained.Certification authority has served as and has issued certificate, supervised, produced evidence, notarized, believed that this method has been successfully applied to ecommerce with guarantee grade in an imperial examination three parts's role.

Electronic security(ELSEC) certificate and digital signature are signed e-file, and the contrast traditional seal is as follows to the signature contrast situation of paper document:

Electronic security(ELSEC) certificate and digital signature are by numerical ciphers, rely on the webserver of certification authority to carry out authenticating user identification, a kind of pattern that e-file is encrypted, deciphered, carries out information transmission and business transaction by electric network.Though improved the security of network trading,, do not had traditional seal directly to be presented at the status of symbol " evidence " in the literal of adding a cover, the figure directly perceived from " evidence " angle of present legal sanction.

Electronic security(ELSEC) certificate and digital signature need be carried out operations such as network inquiry, file encryption, deciphering, it is more loaded down with trivial details not only to seem, and need certain technical foundation in the use, make the people who does not possess computer elementary operation technical ability and network technology can feel inconvenience, non-professional personnel also need certain training, just can use freely, then everybody can use traditional seal.

Use electronic security(ELSEC) certificate and digital signature to carry out network trading certain risk is arranged, after the webserver of certification authority is under attack, or when breaking down, inquiry, the verification process of electronic security(ELSEC) certificate and digital signature are hindered, and can not normally use, certification authority and user will suffer a loss, and traditional seal does not then have this worry.

Electronic security(ELSEC) certificate and digital signature have strengthened the business transaction cost, the client more for a long time in commercial user's transaction, if each transaction all needs webserver inquiry, authentication by certification authority, the network inquiry of payment authentication mechanism takes so, expense such as the single premium of certification fee, credit strengthens transaction cost, and traditional seal does not have this expense.

Because electronic security(ELSEC) certificate and digital signature are numerical ciphers, have lost the cultural connotation that Chinese traditional seal comprised.Signature and traditional seal to file are different sensuously to the paper document signature, do not meet Chinese traditional habit.

Though the electronic security(ELSEC) certificate is the same with seal with digital signature as can be seen by above analysis all is that file is signed, but can't be equal to a seal on the practical significance, can't resemble and easily e-file be signed the traditional seal signature paper document.
