摘要

The practice of concealing information within various mediums, especially on social media, is on the rise. This article explores an efficient text-based homogeneous steganographic technique utilizing prime indices of the cover text to deploy characters of the secret text. The binary form of the secret text is mapped to Unicode zero-width characters, appended at prime positions. This technique distributes secret text characters over the cover text from an arbitrary starting point, ensuring robustness and efficiency. With optimized chunks and a cyclic embedding nature, the proposed technique maintains the visual structure of the cover text. Experimental results demonstrate an 80% embedding capacity, comparable to state-of-the-art text steganographic approaches.
