Abstract
Dynamic watermarking is a paramount tool for protecting intellectual property and sensitive data in multi-tenant SaaS (Software-as-a-Service) environments. In this paper, we present a new dynamic watermarking model designed for multi-tenant SaaS applications where various clients share resources and infrastructure. Compared to static watermarking, dynamic watermarking enables the application of individual, tenant-related watermarks at runtime without compromising performance or user experience for data streams, reports, or application content. The framework utilizes tenant-aware contextual metadata to create, embed, and trace watermarks, enabling the detection of traceable data leakage, unauthorized data sharing, and audit approaches. Strong cryptographic techniques are used to protect against tampering, watermark removal, or collusion attacks, thereby upholding the integrity and non-repudiation of the watermarking procedure.
