一种基于方向映射与多区域嵌入的H.265/HEVC视频隐写方法
A H.265/HEVC video steganography method based on directional mapping and multi-region embedding
摘要
Abstract
In recent years,video steganography for H.265/HEVC attracted considerable attention.Among them,video methods that employ prediction unit(PU)as embedding carriers have become a re-search focus in this field.Such methods achieve information hiding by designing mapping rules between secret messages and PU.However,since the embedding of secret information induces substantial modi-fications to the prediction units,their resistance to steganalysis is relatively weak.To address this issue,this paper proposes a H.265/HEVC video steganography method based on PU directional map-ping and multi-region embedding.The proposed method first extracts the partition mode combinations of two adjacent PU from 8×8 and 16×16 coding unit(CU),and maps them to a two-dimensional coor-dinate through directional mapping.Then,for different PU partition mode combinations,a multi-region embedding strategy is further designed to achieve high-capacity adaptive steganography with minimal modification distortion,thereby enhancing the method's resistance to steganalysis.Experimental results demonstrate that the proposed method out-performs existing PU-based video steganography methods in terms of visual quality,bitrate control,and resistance to steganalysis.This method holds significant potential for applications in covert video communication.关键词
