        <p>Traceable Codes and Frameproof Codes are Essential in Secure Communication, Data distribution, and copyright protection. These Combinatorial Codes enable the detection and prevention of malicious activities such as unauthorized redistribution and collusion. This paper reviews the foundational principles, significant developments, and practical applications of these codes. A Comparative Analysis of these codes highlight the Advancements in Construction Methods and identifies challenges and offers future Research directions.</p>
