Lightweight Laplacian Steganography: A Mathematical Framework for Edge-based Privacy Preservation

Key Points

• Laplacian steganography enhances privacy preservation by embedding data within edges, promoting security.
• Key evidence shows a substantial reduction in detectable alterations—95% effectiveness against traditional methods.
• Analysis of edge-based techniques emphasizes their mathematical framework for improved steganographic performance.
• This approach may enable broader applications in data security; further practical testing is recommended.
