Abstract: The concept of a Virtual Human represents an advanced interactive interface that bridges users with digital information, offering an increasingly realistic experience. Recent breakthroughs in Large Language Models (LLMs) and AI-Generated Content (AIGC) have significantly improved the lifelike nature of virtual humans, making them increasingly indistinguishable from real humans. However, this rapid progress raises significant concerns regarding the ethical implications and the reliability of virtual human interactions, particularly in high-stakes, domain-specific scenarios where factual accuracy and trustworthiness are paramount.
