Cryptotrace: A Crytography Driven Framework for Re-Covering Manipulated Text Using Digital Forensicsy

Digital forensics has become an essential domain in cybercrime investigations, where digital text evidence such as emails, chat logs, documents, and system logs plays a vital role. Ensuring the authenticity and integrity of such evidence is critical, as even minor alterations can invalidate legal proceedings and forensic conclusions. Traditional systems primarily focus on encrypting data to protect confidentiality but often overlook integrity verification before decryption. The increasing frequency of cyber-attacks and digital fraud highlights the need for forensic systems that not only secure evidence but also verify its originality. Without proper integrity checks, encrypted evidence may still be tampered with, leading to unreliable forensic out-comes. To address these challenges, Twin Route Forensics introduces a secure and reliable framework that combines authentication, encryption, and hash-based verification. The system ensures that text evidence can only be restored after successful integrity validation, thereby improving the credibility and reliability of dig-ital forensic investigations.
