Reaching Out to the Community — Privacy Commissioner Publishes “Hong Kong Letter” entitled “Artificial Intelligence is a Double-Edged Sword. Tech Firms are Duty-Bound to Ensure Data Security”

Ada CHUNG Lai-ling, published a “Hong Kong Letter” on RTHK Radio 1 on 29 April to highlight the privacy and ethical risks involved in generative artificial intelligence (AI)-powered chatbots. The Privacy Commissioner considered that tech companies, especially AI developers, have a responsibility to ensure data security of their AI systems.

The Privacy Commissioner explained that the operation of generative AI heavily depends on deep learning technology, which involves the use of massive amounts of raw data as training data. The training data may include sensitive personal data provided by users, or collected and copied from the internet. If users inadvertently input sensitive data into AI systems, their personal data may be susceptible to misuse beyond the original purpose of collection of such data.

The Privacy Commissioner agreed that we should treat the emerging technology with caution and openness. While not hindering the long-term development of new technologies, she recommended that the new technology should be regulated through laws, guidelines, industry standards, or even international standards. This would facilitate the development of generative AI in a healthy, lawful and ethical ecosystem.
