S60: if the first authentication result and the second authentication result are to be proved to be successful, when obtaining default sign The second electronic signature that the first electronic signature and the second client that first client is sent in long are sent, is based on the first electronics label Target electronic contract is signed in name and the second electronic signature, obtains contract signing result.

Wherein, preset duration refers to the pre-set effective time signed a contract.Specifically, if the first authentication knot Fruit and the second authentication result are to be proved to be successful, then it is assumed that the identity for signing both sides is authentic and valid, then prompts to sign both sides The operation signed in preset duration to the signature blocks in target electronic contract.Wherein, the label in target electronic contract Name module is configured with a signature plug-in unit, and for signing electronically, user can click in the signature blocks in target electronic contract Signature plug-in unit, that is, can trigger and sign with the associated signature plug-in unit of signature blocks.The signature plug-in unit includes signature area domain and guarantor Button is deposited, user clicks the save button in signature plug-in unit, signature plug-in unit can be made to pass through canvas element when signing completion The method of the acquisition electronic signature of middle open source obtains the electronic signature that user saves.The electronic signature includes that the first client is formed First electronic signature or the second client formed second electronic signature.Server passes through the first electronic signature and second is electric Son signature is filled at the signature blocks in target electronic contract, and contract signing can be completed, and obtains contract signing result.It can manage Solution, to prevent malice from drawing dotted-line time, causes user sharp by the way that the effective time i.e. preset duration signed a contract is arranged Benefit incurs loss.Specifically, it if being more than preset duration, needs to verify the identity of user again, to ensure the person of contracting The authenticity and validity of part.

In the present embodiment, the second client is sent to by the target electronic contract in requesting contract signing and is carried out to mesh Content in mark electronic contract is appraised and decided, and knows the content in target electronic contract with contract of guarantee recipient.Then, using default It verifies keyword and information extraction is carried out to target electronic contract, and using the both parties' information got to the first authentication Image and the second authentication image carry out authentication, to ensure that both parties' information and user upload in target electronic contract The first authentication image and the second authentication image in corresponding identity information be consistent, contract of guarantee sign have Effect property.Then, based on default words art, what the first original speech information and the second client for obtaining the transmission of the first client were sent Second original speech information simultaneously verifies it, obtains the second authentication as a result, agreeing to contract to ensure to sign both sides In provision content, the validity of contract of guarantee.Later, it is verified in the first authentication result and the second authentication result It is electric then to obtain the first electronic signature and the second client that the first client is sent in default signing duration are sent second for success Son signature, to prevent malice from drawing dotted-line time.Finally, based on the first electronic signature and the second electronic signature to target electricity Sub- contract is signed, and contract signing can be completed, and obtains contract signing result.The contract signing process can be closed in same electronics It is carried out in platform, without being uploaded to third party's signing platform, user can independently contract, and transparent procedures of contracting guarantees The reliability for process of contracting.

In one embodiment, as shown in figure 3, in step S30, i.e., using both parties' information to the first authentication image Authentication is carried out with the second authentication image, obtains the first authentication as a result, specifically comprising the following steps:

S31: the corresponding camera of starting the first client and the second client is remotely monitored, and obtains the first monitoring view Frequency and the second monitor video respectively extract the first monitor video and the second monitor video according to default interception rule, obtain The first verifying frame image and second is taken to verify frame image.

Wherein, it presets interception rule and refers to according to the preset time interval the repeatedly rule of interception video.First monitoring view Frequency refers to the video flowing of the corresponding camera real-time recording of the first client.Second monitor video refers to that the second client is corresponding The video flowing of camera real-time recording.First verifying frame image is to intercept according to default interception rule to the first monitor video Acquired frame image.Second verifying frame image be according to default interception it is regular second monitor video intercept it is acquired Frame image.Specifically, after contract signing both sides confirm contract terms content, then the first client and the second client are called Corresponding camera is remotely monitored, corresponding to obtain corresponding first monitor video of the first client and the second client Second monitor video, and the first monitor video and second are monitored respectively according to default interception rule (such as intercepting a frame every 5s) Video is intercepted, and the first verifying frame image and the second verifying frame image are obtained.By repeatedly intercepting video frame images, to ensure The authenticity of contractor.

S32: carrying out Face datection to the first verifying frame image and the second verifying frame image, obtains and the first verifying frame image Corresponding first verifying facial image and the second verifying facial image corresponding with the second verifying frame image.

Specifically, frame image and the second verifying frame image are verified using trained Face datection model inspection first in advance Whether with the presence of face, if the first verifying frame image includes face, using the frame video image as the first verifying facial image. If the second verifying frame image includes face, using the frame video image as the second verifying facial image.Wherein, Face datection mould Type includes but is not limited to use CascadeCNN network to be trained to be detected.CascadeCNN (Face datection) is to classics Violajones method depth convolutional network realize, be it is a kind of detect fast speed method for detecting human face. Violajones is a kind of Face datection frame.Specifically, if not including in the first verifying frame image or the second verifying frame image Next frame in intercepted first verifying frame image or the second verifying frame image is then carried out Face datection, Zhi Daojian by face The image comprising face is measured, includes the frame image of facial image as the first verifying facial image or the second verifying face using this Image.

S33: identifying the first authentication image and the second authentication image using OCR identification technology, obtains And corresponding first subscriber identity information of the first authentication image and second user body corresponding with the second authentication image Part information.

Wherein, the first subscriber identity information refers to user's body corresponding with the first authentication image that the first client uploads Part information.Second user identity information refers to user identity corresponding with the second authentication image letter that the second client uploads Breath.In the present embodiment, the first subscriber identity information and the second identity information can be specially identification card number and name.Certificate OCR knows Other technology is taken pictures by mobile phone or the terminal device with camera to certificate, and verify using OCR character recognition technology Part photo does OCR Text region, extracts the technology of user basic information.This technology is increasingly recognized and is made by vast consumption user With not only having gathered certificate identification further includes driver's license identification, driving license identification, passport identification, Car license recognition, the knowledge of bank's card number Not, the function of the ensembles such as business card recognition and document identification, having at low cost, use environment, conveniently function is easy the excellent of extension Point.Specifically, the first authentication image and the second authentication image are identified using OCR identification technology, to obtain First subscriber identity information and second user identity information are not necessarily to user manual editing identity information, can be directly by uploading the One identity authentication image and the second authentication image, can the first subscriber identity information of quick obtaining and second user identity letter The case where ceasing, effectively manual editing being avoided to make mistakes, it is ensured that the accuracy of both parties' identity.

S34: the first subscriber identity information and second user identity information are matched with both parties' information, acquisition With processing result.

Specifically, by name and identification card number in the first subscriber identity information and the contract side of drafting in both parties' information Name and identification card number matched；It will be in the name and identification card number and both parties' information in second user identity information The name and identification card number of contract recipient matches, and obtains matching treatment result.Understandably, only when the first user identity Information and the success of both parties' information matches and second user identity information and the success of both parties' information matches, can just obtain With successful matching treatment as a result, then proving in the identity information and target electronic contract in the authentication image of user's upload Both parties identity information it is consistent.If the first subscriber identity information and/or second user identity information and both parties believe It fails to match for breath, then obtains the matching treatment that it fails to match as a result, then proving the identity in the authentication image of user's upload Information and the identity information of the both parties in target electronic contract are inconsistent, the authentication image uploaded by verifying user In identity information it is whether consistent with the identity information of the both parties in target electronic contract, to guarantee subsequent contractor's identity Authenticity verification is effective.

S35: if matching treatment result is successful match, by the first verifying facial image and the second verifying facial image hair Third party's public security system is given, the first ID card verification result that third party's public security system returns is obtained.

Wherein, third party's public security system can refer to the verifying system of public security organ.Specifically, server is being got After successful matching treatment result, it can be linked to identification card number of third party's public security system based on contract signing both sides, inquired The first real human face image corresponding with the identification card number of contract signing both sides and the second real human face image in database, and will First verifying facial image is compared with the first real human face image, by the second verifying facial image and the second real human face figure As comparing, to obtain the first authentication as a result, signing the authenticity of both sides' identity with guarantee.Specifically, if first tests Witness's face image and the success of the first real human face images match and the second verifying facial image and the second real human face images match Success, then obtain the first authentication result being proved to be successful；Conversely, if the first verifying facial image and the first real human face figure It fails to match and the second verifying facial image and the second real human face images match fail for picture, then obtains the first body of authentication failed Part verification result.

In the present embodiment, first using OCR identification technology to the first authentication image and the second authentication image into Row identification, to obtain the first subscriber identity information and second user identity information, so as to by both parties' information and the first user Identity information and second user identity information are matched, it is ensured that both parties' information and the first subscriber identity information and second are used Family identity information is consistent, namely ensure user upload authentication image in subscriber identity information and target electronic close With in both parties' information be consistent, prevent from claiming the identity of others fraudulently authentication image the case where, it is ensured that contract signing it is effective Property.Again by the way that the first verifying facial image comprising face and the second verifying facial image and the will be truncated in monitor video The real human face image stored in tripartite's public security system compares, to obtain the first authentication as a result, double to guarantee to sign The authenticity and validity of square identity.

In one embodiment, as shown in figure 4, in step S33, i.e., with OCR identification technology to the first authentication image and Second authentication image identified, obtains the first subscriber identity information corresponding with the first authentication image and with second The corresponding second user identity information of authentication image, specifically comprises the following steps:

S331: processing, gray processing processing are sharpened to the first authentication image and the second authentication image respectively It is handled with perspective transform, obtains corresponding first image to be verified of the first authentication image and the second authentication image is corresponding The second image to be verified.

S332: identifying the first image to be verified and the second image to be verified using OCR identification technology, obtains and the Corresponding first subscriber identity information of one image to be verified and second user identity information corresponding with the second image to be verified.

Wherein, the first image to be verified is to carry out gray proces, Edge contrast and perspective to the first authentication image to become Change the image to be verified of the exclusive PCR obtained after processing.Second image to be verified is to carry out gray scale to the second authentication image The image to be verified of the exclusive PCR obtained after processing, Edge contrast and perspective transform processing.

Specifically, due to that may include multiple color in the first authentication image or the second authentication image, and face Color itself is highly susceptible to the influence of the factors such as illumination, and similar object color has many variations, so color itself is difficult to There is provided key message, it is therefore desirable to gray processing processing be carried out to the first authentication image or the second authentication image, obtained Grayscale image reduces the complexity and information processing capacity of image with exclusive PCR.

Since the first authentication image or the second authentication image may have different degrees of inclination, mould is influenced Therefore type recognition result need to carry out perspective transform (correction) to the first authentication image or the second authentication image, i.e., will First authentication image or the second authentication image projection obtain the figure after correcting to the process of a new view plane Picture.In the present embodiment, the processing method of perspective transform includes but is not limited to use in OpenCv PerspectiveTransform () function carries out perspective transform processing.OpenCV is one and includes a large amount of open sources API (interface) Cross-platform computer vision library, while providing the interface of the language such as Python, Ruby, MATLAB, realize image procossing With many general-purpose algorithms in terms of computer vision.

In order to be apparent from the details of the edge of image, contour line and image, need first to carry out the image after perspective Edge contrast obtains sharpening image, to remove background lines, improves OCR recognition accuracy.In the present embodiment, Edge contrast Method includes but is not limited to use common Laplace operator in currently available technology, sobel (weighted average difference) operator Following formula can be used to contract by taking sobel Operator Method as an example with any one in Prewitt (average difference) operator Corresponding picture element matrix M (i, j) is signed to be converted:

A=| (M (i-1, j-1)+2M (i-1, j)+M (i-1, j+1))-(M (i+1, j-1)+2M (i+1, j)+M (i+1, j+ 1))|

B=| (M (i-1, j-1)+2M (i, j-1)+M (i+1, j-1))-(M (i-1, j+1)+2M (i, j+1)+M (i+1, j+ 1)) S (i, j)=A+B

Wherein, M (i, j) indicates the corresponding picture element matrix of image after perspective.S (i, j) indicates that the image after perspective is corresponding Picture element matrix, A indicate horizontal direction weighted factor, B indicate vertical direction weighted factor.

In the present embodiment, by being sharpened processing, gray scale to the first authentication image and the second authentication image Change processing and perspective transform processing, to realize the purpose denoised to image, improves to be tested to first using OCR identification technology The recognition accuracy that card image and the second image to be verified are identified.

In one embodiment, as shown in figure 5, in step S40, that is, the first original speech information and the second raw tone are based on Information obtains the second authentication as a result, specifically comprising the following steps:

S41: carrying out denoising to the first original speech information and the second original speech information using voice enhancement algorithm, It obtains among the first corresponding intermediate voice information of the first original speech information and the second original speech information corresponding second Voice messaging.

Wherein, the first intermediate voice information is institute after being denoised using voice enhancement algorithm to the first original speech information Obtained purer voice messaging.Second intermediate voice information be using voice enhancement algorithm to the second original speech information into Obtained purer voice messaging after row denoising.

Specifically, since sound pick-up outfit collects raw tone generally all with noise, including the noise in background environment And the noise generated in Recording Process.These carry the voice messaging of noise when carrying out speech recognition, will affect voice knowledge Other accuracy, therefore, it is necessary to carry out denoising to the first original speech information and the second original speech information, with from voice Purer voice (i.e. the first intermediate voice information and the second intermediate voice information) is extracted in information as far as possible, knows voice It is more inaccurate.In the present embodiment, the method denoised to the first original speech information and the second original speech information includes But it is not limited to using spectrum-subtraction, EEMD decomposition algorithm and the unusual value-based algorithm of SVD etc..

S42: feature is carried out to the first intermediate voice information and the second intermediate voice information using speech feature extraction algorithm It extracts, obtains corresponding first phonetic feature of the first intermediate voice information and corresponding second voice of the second intermediate voice information is special Sign.

Wherein, the first phonetic feature and the second phonetic feature include but is not limited to filter characteristic.Filter (Filter- Bank, abbreviation Fbank) it is characterized in common phonetic feature in speech recognition process.Since Meier commonly used in the prior art is special Sign can carry out dimension-reduction treatment to voice messaging in carrying out model identification process, lead to the loss of partial information, above-mentioned to avoid Problem occurs, and in the present embodiment, replaces common Meier feature using filter characteristic.

S43: the first phonetic feature and the second phonetic feature are input in preparatory trained speech recognition modeling respectively It is identified, obtains the corresponding first identification text of the first phonetic feature and the corresponding second identification text of the second phonetic feature.

It is understood that speech recognition modeling includes preparatory trained acoustic model and language model.Wherein, acoustic model is For obtaining the corresponding aligned phoneme sequence of target voice feature.Phoneme is by unit the smallest in voice, it will be appreciated that for inside Chinese character Phonetic.Such as: Chinese syllable ā () only one phoneme, à i (love) is there are two phoneme, and there are three phonemes etc. by d ā i (slow-witted).Sound The training method for learning model includes but is not limited to that GMM-HMM (mixed Gauss model) is used to be trained.Language model is to be used for Aligned phoneme sequence is converted to the model of natural language text.Specifically, server is respectively by the first phonetic feature and the second voice Feature is input in preparatory trained acoustic model and is identified, obtains the corresponding aligned phoneme sequence of target voice feature, then The aligned phoneme sequence that will acquire is input in preparatory trained language model and is identified, obtains corresponding identification text, i.e., and the One identification text and the second identification text.

S44: the first identification text and the second identification text and default words art are subjected to transcription comparison respectively, obtain the second body Part verification result.

Specifically, the first identification text and the second identification text and default words art are carried out transcription comparison respectively by server, Only when the first identification text and default words art transcription comparison success and the second identification text and default words art transcription comparison success, then The second authentication result being proved to be successful.Even first identification text is known with default words art transcription comparison failure and/or second Other text and default words art transcription comparison failure, then obtain the second authentication result of authentication failed.

In the present embodiment, by using voice enhancement algorithm to the first original speech information and the second original speech information into Row denoising is improved using preparatory trained speech recognition modeling with excluding noise jamming to the first original speech information and the The recognition accuracy that two original speech informations are identified.Finally, by the first identification text and the second identification text and default words Art carries out transcription comparison, obtains the second authentication as a result, guaranteeing to ensure to sign the provision content in both sides' agreement contract The validity of contract.

In one embodiment, as shown in fig. 6, before step S60, i.e., based on the first electronic signature and the second electronic signature Target electronic contract is signed, before obtaining contract signing result, which further includes following steps:
