Chaya

Abstract

1. Introduction

Chaya is for your privacy. Chaya is backed by research (I will publish public version whitepaper on xerohack.com), and has proven to be by far the most effective image steganography tool as compared to other FOSS image steganography tools.

United Nations Declaration of Human Rights (UDHR) 1948, Article 12 - “No one shall be subjected to arbitrary interference with his privacy, family, home or correspondence, nor to attacks upon his honor and reputation. Everyone has the right to the protection of the law against such interference or attacks.” International Covenant on Civil and Political Rights (ICCPR) 1966, Article 1 - "No one shall be subjected to arbitrary or unlawful interference with his privacy, family, home or correspondence, nor to unlawful attacks on his honor or reputation. Everyone has the right to the protection of the law against such interference or attacks."

2. Objective

7. Future Enhancements

Suggested extensions you can add to make this your own project.

• Add logging and alert notifications (email / Telegram)
• Write a threat model document for the tool
• Package it with Docker for safe lab testing

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

1. Which threat or attack does this project defend against?
2. What detection or protection technique is used and what are its limits?
3. How are false positives and false negatives handled?
4. Which cryptographic algorithms or security standards are involved?
5. What legal and ethical rules apply when testing a tool like this?
