WEB TEXT–BASED COVERLESS INFORMATION HIDING METHOD

Abstract

Coverless information hiding has gained attention for its ability to conceal secret information (SI) in carriers without altering them. To address challenges such as low hiding capacity (HC) and mismatches in large-scale text data, this paper proposes a novel method that leverages massive web text resources. First, web crawler technology is employed to collect web texts related to the SI, forming a comprehensive webtext library. Next, relevant texts containing the SI are retrieved, and the optimal text is selected. The position of the SI within the chosen text is then represented using a 2-D coordinate system. Finally, the URL of the selected web text is combined with the location information and sent to the recipient. Experimental results demonstrate improvements in hiding capacity, success rate, and overall security
