Abstract
A new flaseproof method of sealed file is featured as using Hash function algorithm to carry out file summary at time when the file is sealed by electronic seal, generating one-way Hash value with constant length and using it as characteristic digital identification of the file seal.
Description
The present invention relates to cryptography and anti-counterfeiting technology technology, refer in particular to the method for anti-counterfeit of a kind of new file of under computer network environment, using of affixing one's seal.
China legal entity carries out official seal representative system.Seal is as the symbol of official's right, personal credit and the voucher of social interaction, in the use history in existing thousands of years of China, " with seal " and " affixing one's seal " are the power in the external activity of government and enterprise and the expression of promise, and therefore, file, document all are " it are effective to affix one's seal " for thousands of years.Seal is not only the symbol of official power, personal credit, and has become the gem of art of a kind of uniqueness in the magnificent cultural and historical in China and even east, the world.
Heap file in E-Government and the e-business implementation needs " affixing one's seal ", " with seal ", traditional seal used with management method and some insurmountable problems occurred in face of the hi-tech information age, had formed the bottle footpath of E-Government and e-business implementation.
How does seal use in the strange land and how to confirm? how does the authenticity of stamped signature file strange land output guarantee? how to avoid swelling and forgery of E-seal? do you how to confirm the E-seal forged?
Because falsification of seal can obtain interests, this type of criminal activity exists to some extent in the different departments and the industry of society.
In international computer theory and the engineering practice, the operational method of Hash (HASH) function is provided, with hash function (Hash Functions) algorithm the file of different length is made a summary, generation has unidirectional (irreversible operation) hash (HASH) value of regular length, be message digest (Message Digest Algorithms), also claim digital finger-print, algorithmic formula decision cryptographic hash is the length of message digest, and this length decision protection computer is decoded the intensity of attacking.Cryptographic hash is a message digest provides the method for digital signature in E-Government and the ecommerce with asymmetric encryption.
The best way that addresses this problem is:
A kind of new anti-counterfeiting method for file of affixing one's seal is provided, utilize the characteristics of unidirectional (irreversible operation) hash (HASH) value with regular length of hash function to make that E-seal is not reproducible, the stamped signature process is undeniable, signed file and have uniqueness, stamped signature file and E-seal and have unique incidence relation, can effectively prevent to forge, move, can swell E-seal.
The objective of the invention is:
A kind of new anti-counterfeiting method for file of affixing one's seal is provided, utilize the characteristics of unidirectional (irreversible operation) hash (HASH) value with regular length of hash function to make that E-seal is not reproducible, the stamped signature process is undeniable, signed file and have uniqueness, stamped signature file and E-seal and have unique incidence relation, can effectively prevent to forge, move, can swell E-seal.
Advantage of the present invention is:
The digital signature E-seal has the exchange of uniqueness identification data with the file of being signed, technology of using and the legislation of international digital signature integrate with, file seal literary composition can not be cloned imitated, for the user has avoided law hidden danger,, the seal in E-Government and the ecommerce provides the otherwise effective technique assurance for using.
The object of the present invention is achieved like this:
A kind of new anti-counterfeiting method for file of affixing one's seal is characterized in that affixing one's seal file to use the hash function algorithm is hash function (Hash Functions) algorithm the file of the affixing one's seal uni-directional hash with regular length (HASH) value that the produces specific numeral identification as the file seal impression of making a summary.
A kind of new anti-counterfeiting method for file of affixing one's seal according to claim 1 is characterized in that the uni-directional hash with regular length (HASH) value as the specific numeral identification of file seal impression can be arranged in the periphery of seal impression frame.
A kind of new anti-counterfeiting method for file of affixing one's seal according to claim 1 is characterized in that can being arranged in the seal impression frame as the uni-directional hash with regular length (HASH) value of the specific numeral identification of file seal impression.
A kind of new anti-counterfeiting method for file of affixing one's seal according to claim 1 is characterized in that can being arranged in above the frame of seal impression frame as the uni-directional hash with regular length (HASH) value of the specific numeral identification of file seal impression.
A kind of new anti-counterfeiting method for file of affixing one's seal according to claim 1, it is characterized in that can using bar code and square matrix code as data carrier as the uni-directional hash with regular length (HASH) value of the specific numeral identification of file seal impression, and with its graphic making in this document.
How describe the present invention in detail below in conjunction with embodiment realizes:
A kind of new anti-counterfeiting method for file of affixing one's seal is characterized in that affixing one's seal file to use the hash function algorithm is hash function (Hash Functions) algorithm the file of the affixing one's seal uni-directional hash with regular length (HASH) value that the produces specific numeral identification as the file seal impression of making a summary.
A kind of new anti-counterfeiting method for file of affixing one's seal according to claim 1 is characterized in that the uni-directional hash with regular length (HASH) value as the specific numeral identification of file seal impression can be arranged in the periphery of seal impression frame.
A kind of new anti-counterfeiting method for file of affixing one's seal according to claim 1 is characterized in that can being arranged in the seal impression frame as the uni-directional hash with regular length (HASH) value of the specific numeral identification of file seal impression.
A kind of new anti-counterfeiting method for file of affixing one's seal according to claim 1 is characterized in that can being arranged in above the frame of seal impression frame as the uni-directional hash with regular length (HASH) value of the specific numeral identification of file seal impression.
A kind of new anti-counterfeiting method for file of affixing one's seal according to claim 1, it is characterized in that can using bar code and square matrix code as data carrier as the uni-directional hash with regular length (HASH) value of the specific numeral identification of file seal impression, and with its graphic making in this document.
Job step:
One. in computer system, prepare the electronics die of official seal
Two. prepare to draft a e-file
Three. the e-file of preparing to sign and issue is carried out the hash function computing, draw one group of uni-directional hash (HASH) value with regular length, i.e. cryptographic hash.
Four. the electronics die of this numerical value and official seal is synthesized an image file, i.e. cryptographic hash seal.
Five. will be that the cryptographic hash seal is attached to the assigned address of preparing the e-file sign and issue, generally be to cover year Gai Yue on the date.
Six. finishing basic file generative process, can will be that cryptographic hash converts the figure placement of bar code and square matrix code to as in the file.
