How would you build a tool to authenticate products sold on TikTok Shop?

Focus on identifying the key stakeholders involved in the product authentication process, such as sellers, buyers, and TikTok Shop administrators. Consider the types of products sold and the potential for counterfeit items, and outline the specific features your tool would need to address these challenges. Discuss the user experience for both sellers and buyers, including how to streamline the authentication process while ensuring security and trust. Finally, think about how you would integrate this tool with existing TikTok Shop functionalities and any potential partnerships with third-party verification services.
