Description
Technical field
The utility model is related to signature recognition device equipment technical field, is specially a kind of simple leader's signature recognition device.
Background technology
Signature recognition, mechanics identification of also referred to as signing, coming from everyone has oneself unique writing style.Signature mirror
Surely it is divided into on-line signature identification and static signature identifies two kinds.The former is the signature sample that writing people is gathered by handwriting pad, is removed
Outside the coordinate of collection writing point, some systems also gather the data such as pressure, the angle held a pen;The latter is inputted by scanner
Signature sample.
With the development of information technology, biometric identity identification including handwritten signature is unique due to its height
Property with reliability turn into identification study hotspot.Pass through characteristic information and actual signature sample of the computer handwritten signature
It is compared, to recognize the technology of the handwritten signature true and false, its principle is that everyone signature is unique and at one section
It is nonvoluntary in phase to change.Handwritten signature has not amnestic, naturality, sharing, while also having certain relatively unstable
Property, therefore high requirement is proposed to recognizer.It is main herein to study on-line handwritten signature verification, with characteristic value and feature letter
The method that number is combined.Handwritten signature identifying system system must have enough robustness to take into account systematic function again, while
Refuse rate by mistake and receive by mistake between rate to find equalization point according to actual conditions.Ripe signature recognition system has before wide application
Scape, such as finance, security and e-commerce field；ERP System, the office automation system and E-Government field.
Signing messages collection after must carry out first pretreatment includes the first stroke of a Chinese character processing, merge, removal isolated point and redundant points,
The processing of falseness lift pen, smooth and slant correction etc., are eliminated as much as misleading the factor of recognition result.Due to Time Warp effect,
Need to find the Optimum Matching between pen section.
There are many weak points in current signature recognition device, because the mankind write dynamic stereotype in actual use
Not immobilize, the dynamic range of signature is very big, only from font, there may come a time when to cannot be distinguished by actual signature and puppet
Signature is made, rate is refused by mistake and receives that rate is high by mistake, static signature is easier to forge, and the difficulty of identification is also than larger, it is therefore desirable to a kind of
Simple leader's signature recognition device.
Utility model content

Compared with prior art, the beneficial effects of the utility model are：The device structure is scientific and reasonable, uses secure side
Just, must carry out pretreatment after signing messages collection first includes first stroke of a Chinese character processing, merges, removes isolated point and redundant points, falseness
Pen processing, smooth and slant correction etc. are lifted, is eliminated as much as misleading the factor of recognition result.Due to Time Warp effect, it is necessary to
Find the Optimum Matching between pen section.Normal operation method method is advised using dynamic time, Optimum Matching, Jin Erji are sought by recursive procedure
Calculate the similarity degree between two signatures of " distance " sign of each characteristic vector.On feature selecting, generally naked eyes are basis
Static geometric properties judge that in fact such as pressure, speed, acceleration feature can also reflect personal characteristics and be more difficult to imitate；
It is provided with pressure sensitive plate, pressure and stroke tendency when pressure sensitive plate can detect writing, and record storage is got off, enter
And improve the accuracy of identification；Be provided with feature extraction plate, can first stroke of a Chinese character processing, merge, remove isolated point and redundant points, falseness
The pretreatment of pen processing, smooth and slant correction etc., and then exclusive PCR are lifted, accuracy rate is improved.
