The method and device of business license is forged in identification provided in an embodiment of the present invention, determines the steady of business license to be identifiedThe cryptographic Hash of localization；Then judge in data base, if there is the coupling business license of business license to be identified, coupling business is heldCryptographic Hash identical business license according to the stable region of cryptographic Hash and business license to be identified for stable region；If existing, continueThe continuous quantity determining coupling business license；And then according to quantity, identify business license to be identified.It is only necessary to determine during being somebody's turn to doThe cryptographic Hash of stable region and the quantity mating business license, need not be to all pixels on business license image to be identified and dataEach business license in storehouse is compared, and reduces the time that business license is forged in identification, realizes raising identification and forges businessThe purpose of the efficiency of license.
Specific embodiment
Purpose, technical scheme and advantage for making the embodiment of the present invention are clearer, below in conjunction with the embodiment of the present inventionIn accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described it is clear that described embodiment isThe a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those skilled in the art are not havingThere is the every other embodiment being obtained under the premise of making creative work, broadly fall into the scope of protection of the invention.Herein belowIt is to combine accompanying drawing and preferred embodiment, detailed to the specific embodiment of foundation the present patent application, structure, feature and its effectExplanation.
Fig. 1 identifies the flow chart forging business license embodiment one for the present invention, including：
101st, determine the cryptographic Hash of the stable region of business license to be identified.
In the embodiment of the present invention, Hash (Hash) the value identical business license of stable region adopts same template, stableDomain refers to the position infrequently changed when user transforms according to template, the position that such as national emblem position, " business license " four Chinese characters are locatedPut.The collection of pixels that connected domain is made up of the neighbor with same pixel value.
In this step, for current business license to be identified, all of connection is detected by connected domain calibration algorithmDomain, the then characteristic filter connected domain according to different stable regions, thus filtering out incoherent region, then calculate each stableThe cryptographic Hash in domain.In filter process, tone saturation lightness (Hue Saturability Value, HSV) spatial mode can be adoptedType, RGB (Red Green Blue, RGB) model, blue or green product Huang (Cyan Mageata Yellow, CMY) model setting are stableThe feature in domain.For example, then the feature arranging national emblem in business license to be identified is taking using HSV space model as a example：H(Hue)The ratio of value between 110 to 150 for the passage is more than 0.3.
102nd, judge in data base, if there is the coupling business license of described business license to be identified, described coupling battalionThe cryptographic Hash of the stable region of industry license is identical with the cryptographic Hash of the stable region of described business license to be identified.
After determining the cryptographic Hash of each stable region, compare business license to be identified and hold with each business in data baseWhether the cryptographic Hash according to corresponding stable region is identical, if identical, will have identical Kazakhstan with business license to be identified in data baseThe business license of uncommon value is as coupling business license.
As in a kind of feasible implementation, in data base, all business licenses with identical cryptographic Hash are stored inSame a line, the index of this row is cryptographic Hash.Consequently, it is possible to after determining the cryptographic Hash of business license to be identified, use this Hash, if there is business license in the corresponding row of this cryptographic Hash, there is business to be identified in database of descriptions and holding in value inquiry data baseAccording to coupling business license.
However, it is determined that going out not existing the coupling business license of business license to be identified in data base in this step, then explanation shouldBusiness license to be identified is not to forge business license, is a legal business license.Now, this business license to be identified is depositedStore up in data base, as new a line.
If there is described coupling business license in 103 described data bases it is determined that the quantity of described coupling business license.
If determining the coupling business license that there is business license to be identified in data base in 102, further determineThe quantity of coupling business license.For example, data base being inquired about according to cryptographic Hash, if there is identical cryptographic Hash, further determining thatThe quantity of business license in the corresponding row of this cryptographic Hash.
104th, according to described quantity, identify described business license to be identified.
Mate after the quantity of business license with business license to be identified in determining data base, according to this quantity, treatIdentification business license is identified.
The method that business license is forged in identification provided in an embodiment of the present invention, determines the stable region of business license to be identifiedCryptographic Hash；Then judge in data base, if there is the coupling business license of business license to be identified, coupling business license is steadyThe cryptographic Hash identical business license of the stable region of the cryptographic Hash of localization and business license to be identified；If existing, continue to determineThe quantity of coupling business license；And then according to quantity, identify business license to be identified.It is only necessary to determine stable region during being somebody's turn to doCryptographic Hash and the quantity mating business license, need not be in all pixels on business license image to be identified and data baseEach business license is compared, and reduces the time that business license is forged in identification, realizes raising identification and forges business licenseThe purpose of efficiency.
Below, with a specific flow chart, the method forging business license is described in detail to be identified to the present invention.ToolBody, can be found in Fig. 2, Fig. 2 identifies the flow chart forging business license embodiment two for the present invention, including：
