Abstract

The invention provides an LED regenerative copying resisting method and system based on light field conversion. The method comprises the steps of: encoding copy images in a copy image set through employing a Transformer encoder to obtain corresponding copy image embedding vectors, and taking a set of all copy image embedding vectors as a copy image embedding vector set; encoding all original images in an original image set through employing the Transformer encoder to obtain corresponding original image embedding vectors, and taking a set of all the original image embedding vectors as an original image embedding vector set; and performing calculation by using the copy image embedding vector set and the original image embedding vector set to obtain a distinguishing score group, using the distinguishing score group for judging whether the original image embedding vector is consistent with a to-be-detected image embedding vector or not, and if yes, judging that the to-be-detected copy image is a new original image. Rapid detection and recognition of the copy images and the original images are achieved, and the calculation time cost of image recognition is reduced.

Description

technical field [0001] The invention belongs to the fields of information security technology and image processing technology, and in particular relates to an anti-LED regenerative copy method and system based on light field conversion. Background technique [0002] In recent years, with the rapid development of mobile Internet, 5G mobile communication and other technologies, and the widespread popularization of high-performance smart terminals, multimedia applications represented by images / videos have experienced explosive growth. The widespread application of multimedia has produced huge economic benefits, but the accompanying copyright disputes have also attracted widespread attention. Rampant piracy seriously damages the economic interests of multimedia content providers and hinders the further promotion and application of multimedia technology. A safe and effective multimedia content protection scheme has become the most urgent technical requirement in current multimedi...
