PRSA: Prompt Stealing Attacks against Real-World Prompt Services

Understand

Recently, large language models (LLMs) have garnered widespread attention for their exceptional capabilities.

• Prompts are central to the functionality and performance of LLMs, making them highly valuable assets.
• The increasing reliance on high-quality prompts has driven significant growth in prompt services.
• However, this growth also expands the potential for prompt leakage, increasing the risk that attackers could replicate original functionalities, create competing products, and severely infringe on developers' intellectual property.
