A blockchain-based image verification method and device

Abstract

The invention discloses an image verification method and apparatus based on a block chain. The method comprises the following steps: uploading a first verification code generated based on a first application program to a network system that is established on the basis of the block chain so as to verify the first application program, wherein the first application program is used for generating an image; and when the first verification code is audited by the network system, uploading a second verification code associated with the image, so that the network system performs first verification on the image by using the second verification code, wherein the second verification code comprises feature information of the image. By adoption of the method, whether the application program for obtaining the image is modified can be judged on the basis of the block chain technology, whether the image obtained by the application program is modified can also be judged, the judgment accuracy is relatively high, and the image does not need to be uploaded to the network system, thereby saving the system resources and reducing the cost.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a blockchain-based image verification method and device. Background technique [0002] With the advancement of science and technology, the ability to process images such as photos and videos is becoming more and more powerful. Illegally modified images often cause bad effects, such as modifying the original image or modifying the image not in accordance with the regulations, especially modifying the original image. To confuse others, but it is becoming more and more difficult to judge whether the image has been modified, so the authenticity of the image is often questioned. Conversely, if the authenticity of the image can be guaranteed, the persuasiveness of the facts can indeed be increased. But at present, to verify whether images such as photos have been modified, it needs to be identified based on the image itself and through complex image analysis. The technical threshold is h...

[0002] With the advancement of science and technology, the ability to process images such as photos and videos is becoming more and more powerful. Illegally modified images often cause bad effects, such as modifying the original image or modifying the image not in accordance with the regulations, especially modifying the original image. To confuse others, but it is becoming more and more difficult to judge whether the image has been modified, so the authenticity of the image is often questioned. Conversely, if the authenticity of the image can be guaranteed, the persuasiveness of the facts can be increased

However, at present, to verify whether images such as photos have been modified, it needs to be identified based on the image itself and through complex image analysis. The technical threshold is high and the identification cost is high.
