Embodiment Construction

[0069] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention.

[0070] Current image tampering detection methods are easily constrained by anti-tampering tools such as image pixel level, format level and scene level, and cannot accurately detect the authenticity of images. Based on this, the present invention provides an image tampering detection method with lower requirements on the pixel level, format level and scene level of the image. First, the semantic description information of the image to be detected is obtained through a fine-grained image description model, and then the The semantic description information of the algorithm is matched with the anomalous rule library, and it is judged whether the ...

Abstract

The present invention relates to an image tampering detection method and device. The method includes acquiring semantic description information of an image to be detected according to a preset fine-grained image description model; matching the acquired semantic description information with a preset abnormal rule library: If the preset anomaly rule library contains the semantic description information, it is judged that the image to be detected is a tampered image; the device can execute the steps of the above method. Compared with the prior art, the image tampering detection method and device provided by the present invention can detect the authenticity of the image more accurately.

Description

technical field [0001] The invention relates to the technical field of computer vision and image recognition, in particular to an image tampering detection method and device. Background technique [0002] Digital image processing software can be used to edit and process images, and accordingly, it is also conducive to image tampering and forgery, resulting in a large increase in tampered images, and even tampered images will appear in news reports and legal evidence, reducing the impact of news media and justice. credibility. [0003] At present, digital image content authentication technology can be used to detect whether an image is a tampered image, and digital image content authentication technology mainly includes active authentication methods and passive authentication methods. [0004] Among them: the active authentication method refers to embedding watermark or digital signature in the process of image generation or before release. However, the active authenticatio...
