DATA LEAKAGE DETECTION SYSTEM USING WATERMARKING AND CRYPTOGRAPHY

Project Algorithm :

Cryptography, Digital Watermarking, Watermark Extraction and Forensic Analysis

Project Overview :

In the era of cloud computing and large-scale data sharing, organizations face the risk of data leakage due to insider threats, unauthorized access, or accidental sharing. Traditional access-control methods cannot fully prevent leaks, especially when authorized users intentionally misuse data. To address this, the project proposes a dual-layer protection system that integrates digital watermarking and cryptography. Sensitive data is first encrypted for confidentiality and then embedded with an invisible watermark that uniquely identifies the authorized recipient. If the data is leaked, forensic analysis of the watermark reveals the source of the leak. This combination ensures data confidentiality during transmission and accountability in case of breaches. The system will be deployed as a web-based platform, enabling secure data upload, encryption, distribution, and leakage detection with traceability.
