Sweden's data protection authority, IMY, is warning young people about the risks of sharing personal information with AI chatbots. The agency cautions that the anonymity offered by these platforms is often illusory, as conversations are used to train underlying language models. Worryingly, nearly 100,000 chats have already become public this year due to user errors. IMY highlights the issue of data security, noting that many users access AI services without paying, raising questions about data handling practices. Petter Flink of IMY emphasizes the security implications of freely available AI. Users should be aware that their private conversations may not be as confidential as they believe, and could potentially be exposed publicly. The warning aims to increase user awareness and promote more cautious interaction with AI technologies.
