Image inpainting-based behavior image secret sharing

摘要: The polynomial-based image secret sharing (ISS) scheme encodes a into n shadows assigned to participants. with high resolution is decoded by Lagrange interpolation when collecting any k or more shadows. Thus, ISS used in applications such as distributive storage the cloud, digital watermarking, block chain, and access control. Meaningful are significant because meaningful decrease suspicion of encryption increase efficiency shadow management. Generally, previously schemes were achieved through embedding cover images using information hiding techniques suffer from large pixel expansion complex decoding procedure. Digital processing, inpainting (texture synthesis), standard technique multimedia applications. It will be highly if can performed processing normal technique. encoding method an entails use mathematical function that sensitive slight change output; therefore, development for performing procedure simultaneously achieving behavior key challenge. In this paper, we exploit (BISS) realize inpainting-based BISS (k, n) threshold. Using screening operations, encoded pixels obtain similar input images. addition, losslessly Experiments given confirm scheme.
