Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
As shown in fig. 1, the method for improving the reliability of the chain link certificate of the scene certificate block provided by the present invention includes the following steps:
(1) the client provides scene information, which means that under different service scenes, according to service requirements, the client needs to provide corresponding identity information or collect information of the client; the method comprises the information of a client such as an image picture, a signature picture, an identity card picture, a sound recording and an electronic form.
(2) The background can carry out information authenticity verification according to the received information.
(3) For example, a background receives images such as client images, signatures and identity cards provided by a client, and the background performs anti-fraud verification on the images, including image classification, malicious and false detection of the images and standard detection of the images, and the three methods are all based on a CNN algorithm. Firstly, automatically classifying the received pictures, and identifying which type of pictures the received pictures belong to. And then judging whether the picture has the conditions of malicious counterfeiting, alteration, cloning and copying, and finally detecting whether the picture meets the standard requirements of the service. After all the checks pass, the next operation can be performed. The image classification utilizes a deep learning technology to perform learning modeling on an image sample (such as an identity card image, a business license image and the like), and when the image is received by a background, the image type can be automatically identified. The malicious and false detection of the image mainly aims at whether the image such as identity information, a business license and the like has synthesis and tampering traces, and the authenticity of image data is ensured. And the image standard detection is to extract the image characteristic value to check according to the service requirement, and whether the image characteristic value meets the service requirement or not.
(4) For example, the background receives the recording information, and the background performs voiceprint recognition on the recording information to ensure that the recording is the own voice. And the voiceprint recognition is to extract the characteristics of the voiceprint by collecting the voiceprint information of the client. When the recording information is acquired, the characteristics of the recording information are extracted and matched with the voiceprint reserved by the client, and if the matching is passed, the recording information shows that the recording information is actually recorded by the client.
(5) And receiving the verified scene information, and calculating a hash value for the scene information. The scene information hash value is calculated because the image data, the video data and the voice data have large data and are not beneficial to storage and processing, so the hash value corresponding to the image data, the video data and the voice data is obtained by adopting a hash value calculation mode.
(6) And applying for a scene certificate by using the user information and the scene information hash value, and registering the user information and the scene information hash value for uplink through a block chain. The scene certificate application is to send the user information, the user certificate and the scene information hash value to the cfca to apply for the scene certificate, and register the user information, the user certificate, the scene information hash value and the signature original text data to the block chain platform.
(7) And after the scene certificate is acquired, signing the service data, and registering the signature data for uplink through a block chain.
As shown in fig. 2, on the other hand, the present invention further provides a system for improving the reliability of chain certificate storage of a scene certificate block, where the system includes a scene information acquisition module, an information authenticity verification module, a hash value calculation module, and a scene certificate application module;
the scene information acquisition module is used for acquiring scene information of a user and sending the scene information to the information authenticity verification module, wherein the scene information comprises an image picture, a signature picture, an identity card picture, a sound recording and an electronic form of the user;
after the scene information is received by the information authenticity verification module, carrying out information authenticity verification according to the received image information and the received sound recording information; for image information, verifying authenticity by adopting image classification, image false detection and image standard detection modes; sending the information passing the verification to a hash value calculation module;
the hash value calculation module receives the verified scene information, calculates a hash value for the scene information, and sends the hash value to the scene certificate application module;
the scene certificate application module applies for a scene certificate by using the user information and the scene information hash value, and registers and chains the user information and the scene information hash value through a block chain; and sending the applied scene certificate to a user, signing the service data after the user acquires the scene certificate, and registering the signature data on the chain through the block chain.
The flow of the invention is specifically explained by taking customer account opening as an example;
1. the customer initiates an account opening application to the service platform, and uploads an identity card photo, a business license photo and other identity information.
2. The service platform pushes the identity card photos and the business license photos to an artificial intelligence platform for image classification, malicious and false detection of the images and standard detection of the images. If the photos have ps, are forged or are not standard, the customer fails to open the account and the customer fails to verify the information, and please provide the identity materials again.
3. If the image detection is passed, the service platform initiates a scene certificate application to the ca certificate platform.
4. And signing the service data by using the scene certificate.
5. And the service platform registers the user information and the scene information hash value to the uplink through the block chain.
6. And feeding back to the user, and completing the business.
