Another exemplary application scene of this specification embodiment can be：

User shows identity document image by terminal device to the client of authoring system, or, user is to mandate The client displaying identity document of system, by the image of client captured identity certificate.Then, client is by identity document image The server of authoring system is reached, is verified by server, and the result is returned to client, checking is based on by client As a result authorized user is determined whether.

Wherein, during this process can occur to cross safety check in user, log in and need to authorize platform etc..In addition, transacting business Whether user user corresponding with identity document needs consistent specific depending on the regulation of business handling side.

The application scenarios of this specification embodiment can also be various other scenes in addition to above-mentioned two kinds exemplified, This is not specially limited, and can be used as long as being technically applicable to the scheme that this specification provides.With reference to attached Figure, describe the technical scheme that each embodiment of the application provides in detail.

Embodiment 1

Fig. 2 is the schematic flow sheet for the auth method that this specification embodiment 1 provides, and referring to Fig. 2, this method can be with Specifically comprise the following steps：

Step 220, the identity document image for obtaining object to be verified；

Wherein, identity document image can be the image that shooting identity document obtains, and identity document can be：Identity card, Interim identity card, academic card, driving license etc. can prove the certificate of object identity to be verified, still to be tested right described in identity document The identity information of elephant, such as：Name, identification card number, student status number etc..

It should be noted that a kind of implementation of step 220 can be：The identity card of collection in worksite object to be verified Part image." scene " herein be need verify identity " scene ", its can be checking identity transacting business scene, example Such as：Handle open an account business when, gather the scene of the image of the identity card of object to be verified；It may not be showing for transacting business , such as：When crossing safety check, the scene of the image of the related certificate of object to be verified is gathered.

Understandable to be with reference to Fig. 1, the mode of " collection in worksite identity document image " can be specially：

User independently opens shooting interface, or, the operation based on user, authoring system calls the camera of terminal device Interface is shot to open, then, the identity document for shooting object to be verified obtains identity document image.

Another implementation of step 220 can be：Obtain the identity document image of the object to be verified formerly gathered. " first " " scene " for being used to distinguish in a kind of upper implementation of step 220 herein, this implementation can be exemplified as：By it The identity document image of preceding shooting is stored in precalculated position, when needing to carry out authentication, is obtained based on storage address corresponding Identity document image.

Step 240, the anti-counterfeiting mark in the source of the identity document image and/or the identity document image is carried out Checking, obtain the first the result；

The source of identity document image in this step can be a variety of sources, such as, shoot the identity document in entity, After ps/non-ps certificate photograph, the copy of certificate, screen reproduction, predetermined shooting field etc..It is to glue that anti-counterfeiting mark, which is, Patch, printing, heat transfer are on subject matter surface, or in subject matter packaging, or subject matter adjunct (such as commodity are listed, business card and Antifake certificate card) on, the mark with anti-fake effect.Such as：Anti-counterfeiting mark on identity card includes：National emblem, certificate title, Great Wall Pattern, the issuing authority of certificate and the term of validity and chromatic pattern etc..

It should be noted that for different business, because its required safe class is different, it is legal optionally to set Source and the integrity degree of anti-counterfeiting mark.For the business that safe class requires higher, such as：Remotely open an account.Need to meet Condition：The source of identity document image is the identity document of entity and possesses complete anti-counterfeiting mark, or meets the condition Probability reaches certain threshold value.And for safe class requirement is than relatively low business, the condition of satisfaction can suitably relax.

It is illustrative to realizing for step 240 by taking " remotely opening an account " as an example below：First, to being tested in step 240 The implementation for demonstrate,proving the source of identity document image is illustrated, including：Verify identity document image whether from real Body certificate, checking identity document image whether with the image sources of collection in worksite in same shooting environmental；Then, based on checking body The implementation in the source of part certificate image, enumerates five kinds of implementations herein.Those skilled in the art on this basis can be with Other implementations are expanded, these modes are within the protection domain of the application：

The first implementation：

This implementation goes for requiring higher occasion to safe class, such as, it is desirable to identity document image Possess complete anti-counterfeiting mark, or meet that the probability of the condition reaches certain threshold value.It is specifically as follows：

It is determined that the anti-counterfeiting mark in identity document corresponding with the type of the identity document image；Based on the false proof of determination Anti-counterfeiting mark in identity document image described in identity verification, and the first the result is determined according to the result, described first The result is used to represent the probability that the identity document image passes through checking.Wherein, anti-counterfeiting mark includes：It is watermark word, micro- It is at least one in contracting word, shading lines, intaglio printing, colour cast, false proof secret mark, font.

It should be noted that different types of identity document is corresponding with different anti-counterfeiting marks, such as：Identity card, passport, Driver's license has corresponding anti-fake mark.Correspondingly, can be based on the certificate class that user selects during transacting business Type determines the type of the identity document image of collection, or, image recognition processing is carried out to the identity document image of collection, with true Determine the type of identity document image.

In addition, understandable be, can be by way of train classification models, by the anti-counterfeiting mark in identity document image As the input of disaggregated model, or, the input using identity document image as disaggregated model, disaggregated model output identity document The probability that image is verified by anti-counterfeiting mark.Wherein, scanning identity document image can be exemplified as in a manner of obtaining anti-counterfeiting mark： Using printing opacity inspection identification watermark word etc..

Second of implementation can be：

This implementation goes for requiring higher occasion to safe class, such as, it is desirable to it is identity document figure The source of picture is entity identities certificate, or meets that the probability of the condition reaches certain threshold value.Specifically can be by following two Scheme is realized：

The first scheme (identity document image is at least one)：

First, first time checking is carried out to the identity document image, to determine the identity document image sources in screen The probability of curtain reproduction；Secondly, carry out second to the identity document image to verify, to determine the identity document image sources In the probability of copy；Finally, based on the identity document image sources in the probability of screen reproduction and from copy Identity document image sources are in the probability of entity certificate described in determine the probability.Wherein, checking for the first time is verified suitable with second Sequence does not limit herein, can also serializable parallel.

In the first scheme, checking for the first time can specifically be carried out as follows：

Based on predetermined special characteristic, the certificate provincial characteristics in the identity document image is detected, to be rubbed with reference to screen The difference of the normal identity document image of that line disaggregated model contrast and the identity document image of screen reproduction between certificate region Property；Wherein, special characteristic can be exemplified as：Screen moire fringes, certificate watermark, print the feature such as reflective.And based on predetermined specific Feature, feature detection is carried out to the frame of the identity document image, and normal identity is contrasted to combine screen frame disaggregated model Otherness between the frame of certificate image and the identity document image of screen reproduction, such as：The identity document figure of screen reproduction As by there is black surround frame.Wherein, special characteristic can be exemplified as：Screen moire fringes, certificate watermark, print the feature such as reflective.It is described Certificate region is the region of identity document corresponding to the identity document image.

In the first scheme, second of checking can specifically be carried out as follows：

Based on Pixel-level feature corresponding to black and white copying part and/or colored photocopy, to the figure of the identity document image As data carry out feature detection.Specific implementation can be based on identity card described in black and white copying part classification DNN model inspections Corresponding Pixel-level feature in part image, determine the probability that the identity document image is black and white copying part.Based on color photocopying Corresponding Pixel-level feature in identity document image described in part classification DNN model inspections, determines the identity document image for coloured silk The probability of color copy.

By the checking of above-mentioned first time and second of checking and then based on screen moire fringes disaggregated model, screen frame point At least one determination in the result of class model, black and white copying part classification DNN models and colored photocopy classification DNN model outputs The source of identity document image is the probability of real entity identities certificate.

Second scheme：

The view data of the identity document image is analyzed, determines the first the result, the first checking knot Fruit is used to represent the identity document image sources in the probability of entity certificate.It is specifically as follows：

Image recognition processing is carried out to the view data of the single-frame images in the identity document image, verifies identity document It whether there is the special characteristic of pixel scale in image, then, the presence situation of special characteristic is true in identity-based certificate image Fixed first the result.Input that can also be using view data as disaggregated model, obtain the first checking of disaggregated model output As a result.Special characteristic can be exemplified as：Screen moire fringes, certificate watermark, printing are reflective etc..

Or

At least two identity document images, the view data progress at least two class images in identity document image are poor Value processing, obtains image difference；Input using described image difference as pre-established disaggregated model, the disaggregated model are used for base The first the result is exported in the image difference of input；Wherein, at least two class images can be to be adopted under different shooting conditions Two class images of collection, such as：A kind of image gathered under a kind of image and flash lamp that are gathered under natural conditions, or, it is different The image gathered under exposure.Further, the object of difference processing can be the image and flash lamp gathered under natural conditions The image of lower collection.

The third implementation can be：

This implementation goes for requiring very high occasion to safe class, such as, it is desirable to it is identity document The source of image is that real entity identities certificate and possess complete anti-counterfeiting mark, or, meet that the probability of the condition reaches Certain threshold value.

Its implementation process is similar to the first and second of implementation, therefore, here is omitted for similarity.In addition, The third implementation also includes：Based on probability of the identity document image by checking and the probability from entity certificate The first the result is determined, that is, determines the confidence level of the identity document of object to be verified corresponding to identity document image.

4th kind of implementation can be：

This implementation goes for requiring higher occasion to safe class, such as, it is desirable to it is identity document figure As deriving from same photographed scene with the first background image, or, meet that the probability of the condition reaches certain threshold value.Wherein, Safe class requirement is related to the identity document image for needing to shoot, such as, it is desirable to it is higher, it is necessary to the identity document image of shooting More and needs are also more from the identity document image of same photographed scene with the first background image.It is specifically as follows：

Before step 220 is performed, one or more background image (following referred to as the first background images) is gathered in advance, Then, identity document image and the first background image are contrasted, it is determined that degree of overlapping between the two.

It is understandable to be, if degree of overlapping between the two is more than certain threshold value, it is determined that both are in same shooting field Completed under scape；Moreover, contrast mode can be between identity document image and individual background image contrast, or It will be contrasted after the long background image of background image combination with identity document image.

Wherein it is determined that both whether the scheme under same photographed scene can include：By the image of the background area In background area contrasted with the first background image, obtain between the identity document image and first background image Degree of overlapping；First the result is determined according to the degree of overlapping, first the result is used to represent the identity Certificate image derives from the probability of same photographed scene with first background image.The background area is the identity document Region in image outside region shared by identity document.

Further to improve the verification the verifying results and efficiency of the 4th kind of implementation, can be based on gathering the identity document image When gyroscope first position information and gather first background image when gyroscope second place information, to both Angle be adjusted, to contrast the background image of background area first under same gyroscope position information, obtain degree of overlapping, and Determine that both are shot in the probability of same photographed scene based on degree of overlapping.

It is exemplified below：Before the image of captured identity certificate is started, shot when gyroscope is in second place information First background image, such as：Desk and its image on periphery.Then, in the case where gyroscope is in first position information, captured identity The image of certificate.Then, the certificate region and background area in identity document image, and the positional information based on gyroscope are separated Background area and the first background image are contrasted, obtains degree of overlapping.Wherein, certificate region is shared by identity document in part certificate image Region.

5th kind of implementation can be：

This implementation goes for requiring higher occasion to safe class, such as, it is desirable to the material of certificate is Really it is the material of certificate, or, meet that the probability of the condition reaches certain threshold value.It is specifically as follows：

Image difference based at least image data acquisition of two class images determines the material of certificate, and then contrasts the certificate Material and corresponding types real docu-ment material, and based on comparing result determine the certificate be real docu-ment probability, make For the first the result.

Understandable to be, different types of certificate may be made by different materials, and certificate material is different, meeting Occurs larger otherness under different shooting conditions.Thus, the image difference of two class images can be inputted to point trained In class model, the first the result of disaggregated model output is obtained.

Understandable to be, above-mentioned several feasible implementations can be based on the safety for treating transacting business and its corresponding requirement Grade and reasonable selection, or, rationally arranged in a crossed manner, here is omitted.

Step 260, the true and false to the identity information in the identity document image are verified, obtain the second checking knot Fruit；

It should be noted that a kind of implementation of step 260 can be：

Online checking is carried out to the identity information in the identity document image, and institute is determined according to the result of online checking State the true and false of identity information.

Wherein, the concrete mode of online checking can be：The citizenship information system of online checking is showed with the People's Bank Based on some Intranets and internetworking platform, forward the People's Bank user to the information sharing system of the Ministry of Public Security and pass through account The verification request that family system, credit investigation system, the respective front-end system of anti money washing system are sent；Receive and forward business bank user And the verification sent by its comprehensive business system by its front-end system is asked；Receive and forward information sharing system of the Ministry of Public Security The verification result of system.

In addition, the object of online checking can include：Text information and card face image in identity information.Text information can Think certificate ID, the name obtained based on optical character identification (Optical Character Recognition, OCR) identification Etc. information, card face image is the head portrait identified.

Step 280, the body for determining based on first the result and second the result object to be verified Part the result.

It should be noted that the first the result and the second the result that are obtained based on step 240 and step 260, this A kind of implementation of step can be：

If the second the result is not pass through, it is determined that the authentication result is not pass through；

Or

If the second the result be by, based on first the result determine the authentication result whether be Pass through.It is specifically as follows：When the probability passed through corresponding to the first the result is less than predetermined threshold, it is determined that the identity is tested Card result is not pass through；The authentication knot is determined when the probability passed through corresponding to the first the result is higher than predetermined threshold Fruit is to pass through.

Another implementation of this step can be：

If second the result is by determining that the authentication result is logical based on the first the result Cross/unsanctioned probability.

For two kinds of implementations of step 280, because each above-mentioned step there may be image taking angle, bat The problems such as taking the photograph quality, it is not the process that an order performs to cause whole flow process, and therefore, the present embodiment provides a decision-making and drawn Hold up, the result entirely verified is assessed with certain rule.It is exemplified below：

Because the influence factor of the first the result may include：Probability that identity document image is verified by anti-counterfeiting mark, Identity document image sources are derived from one in the probability of Same Scene in the probability, ID Card Image and image scene of entity certificate It is individual or multiple, therefore, it is determined that during probability corresponding to the first the result, the conditions such as demand, experience can be based on, to participating in determining Weight corresponding to the influence factor setting of first the result, and it is corresponding based on respective weights and the result of determine the probability first Probability.Such as：Participate in determine the first the result influence factor identity document image verified by anti-counterfeiting mark probability, Identity document image sources are distinguished in the probability, ID Card Image and image scene of entity certificate from the probability of Same Scene For 60%, 70%, 80%, the weight of setting corresponds to 30%, 30%, 40% respectively, then the first checking knot finally calculated Probability corresponding to fruit is 71%.

In addition, in order to lift the speed and efficiency of the detection of certificate authenticity, the above-mentioned source to the identity document image Verified, the anti-counterfeiting mark in the identity document image is verified, and in the checking identity document image The true and false of identity information can be Parallel Implementation.

Understandable to be, the embodiment of the present invention optionally only performs step 220- steps 240, is tested with completing certificate The process of card, such as：

Obtain the certificate image of certificate to be verified；

The anti-counterfeiting mark in source and/or the certificate image to the certificate image is verified, is obtained first and is tested Demonstrate,prove result；

The result of the certificate to be verified is determined based on first the result.

Or

Obtain an at least certificate image for certificate to be verified；

Or

Obtain the certificate image of certificate to be verified；

Verify whether the certificate image and the first background image of live pre-acquired derive from same photographed scene, obtain The result of the certificate to be verified.

Due to, the process of certificate verification is similar to the associated description in above-mentioned steps 220 and step 240, therefore, herein no longer Repeat.In addition, based on being actually needed, above-mentioned each certificate verification scheme arranged side by side can intersect combination, such as：It is " false proof The combination of mark "+" whether from same photographed scene ".

It can be seen that the embodiment of the present invention is by testing the source of identity document image, anti-counterfeiting mark and identity information Card, can effectively solve situations such as forgery of certificate content, reproduction certificate on the premise of without using professional authorized machine, and then be line On handle related service provide meet needed for safe class authentication ability.
