Are You Copying My Prompt? Protecting the Copyright of Vision Prompt for VPaaS via Watermark

Understand

Visual Prompt Learning (VPL) differs from traditional fine-tuning methods in reducing significant resource consumption by avoiding updating pre-trained model parameters.

• Instead, it focuses on learning an input perturbation, a visual prompt, added to downstream task data for making predictions.
• Since learning generalizable prompts requires expert design and creation, which is technically demanding and time-consuming in the optimization process, developers of Visual Prompts as a Service (VPaaS) have emerged.
• These developers profit by providing well-crafted prompts to authorized customers.
