EchoMark Leak Detection Tool is a data leak source identification solution that uses invisible watermarking technology combined with machine learning and computer vision to trace the origin of leaked information. The tool embeds invisible watermarks in messages and documents, enabling organizations to identify the source when sensitive information is leaked. The system can analyze leaks across multiple formats including emails, PDFs, printed documents, mobile photos, and screenshots of sensitive documents. When a leak occurs, users upload the leaked artifact to the leak analysis tool, point to the original file, and receive a detailed report identifying the source. The platform deploys patent-pending detectors that vary based on the type of leak uploaded. Reports include transparent information about detector accuracy and explain how the system determined the leak source. The solution integrates with Microsoft Exchange and Google Workspace to automatically embed watermarks in organizational communications and documents. EchoMark uses perturbation technology and computer vision techniques to maintain watermark invisibility while ensuring detection capability regardless of how the information was leaked or where it appeared. The tool provides organizations with visibility into information security incidents and serves as a deterrent against unauthorized data sharing.
