Nvidia said on Thursday its products have no "backdoors" that would allow remote access or control after China raised concerns over potential security risks in the firm's H20 artificial intelligence chip.

China’s cyber regulator on Thursday said it had held a meeting with Nvidia over what it called “serious security issues” with the company’s artificial intelligence chips. It said US AI experts had “revealed that Nvidia’s computing chips have location tracking and can remotely shut down the technology”.
