Description
Technical field
The utility model is related to one kind has the unique stamp device of printed text feature.
Background technology
According to historical data:Han《Chun Qiu Far Meter Pivot》Record, the race of China before more than 4,000 years use imperial seal as a kind of contract with
Voucher.So far seal is widely used, and the state that persistently grows steadily is presented in the recoverable amount in its market.According to statistics：2015 annual China
It is average daily to newly register the family of enterprise 1.2 ten thousand, all kinds of families of main market players 7746.9 ten thousand in the whole nation, in addition to the five big chapter such as official seal, industry also be present
Seal, operation Shi Yinzhang classes, signet class etc., national seal total amount is huge.
At present, scribing for seal is put on record, is many using administrative vulnerability, is attributed to：（1）The unauthorized use of seal and by
Fraudulent copying uses.（2）With chapter evidence chain serious loss.According to incompletely statistics：China is every year because official seal miscarriage is made
Into loss be up to 127,400,000,000 yuan.（3）Enterprises and institutions etc. can only scribe one piece of official seal according to the provisions of the relevant regulations issued by the State.And usual feelings
Multiple physics official seals or multiple E-seals can be scribed according to business demand under condition, not meet administrative provisions of the country to seal.
And the problem of management of E-seal is more compared with physical unit, it is unfavorable for managing, the checking and mutual trust of E-seal printed text, mutually tests very
Difficulty, it is unfavorable for the units such as enterprises and institutions and carries out every business in a network environment, at the same it is trans-regional, inter-trade bigger using difficulty.
（4）Supervision of the public security department to seal is only limited to scribing for physical seal at present and put on record, and it is not directed to chapter supervision, is more attached most importance to
What is wanted is granting and the supervision almost blank of E-seal.
In a word, the criminal offence carried out with seal is beaten endless repeatly, with the development of science and technology, fraud means are also gradually high
Technicalization, fake equipment technicalization is showed, platform network is solicited, forges object variation etc..These illegal activities damage
Country, political party, group, the prestige of enterprises and institutions, serious directly threatens mass interest, is brought seriously to civil order
Harm.
Therefore, a in advance to authorize and be supervised in time in what one is particularly good at, and can traces afterwards, while has printed text unique
The electrical integrated seal of thing and stamp device of mark are just catering to the use of present physical seal and are managing, use electronics on e-file
Seal and the growth requirement for needing progress printed text and stamp mark retrospect.
The content of the invention
The utility model is directed to a kind of stamp device with printed text unique identification.Ensure seal and electronics in kind
Seal it is safe to use.Realizing simultaneously can be in the e-file of same format while physical seal is affixed one's seal on a paper document
Upper synchronous capping E-seal, solves current physical seal and affixes one's seal on a paper document and lid electronics on corresponding e-file
Seal is asynchronous, it is impossible to the problem of being mutually authenticated.It is same using having for electronic signature according to electronic signature law regulation e-file
