It establishes principles for fairness, accountability, transparency, and privacy, ensuring that AI technologies align with societal values and do not perpetuate biases. This framework helps organizations navigate the ethical implications of their AI applications, addressing potential societal impacts. By adhering to ethical guidelines, developers can foster public trust and promote positive uses of AI technology.
