Tesco's chief executive has outlined plans to use Clubcard data to alert shoppers when they are purchasing too many unhealthy items. The supermarket giant aims to employ artificial intelligence (AI) to track customer shopping habits and guide them toward healthier choices. While the proposal is seen as a positive step by health campaigners combating the obesity crisis, it has raised concerns among privacy advocates. The use of personal data to influence shopping decisions has sparked a debate about the boundaries of consumer surveillance and personal choice.
In comments given to the article, Jake Hurfurt, Head of Research and Investigations at Digital rights group Big Brother Watch (BBW), said: "It is astounding that Tesco's CEO wants to use this data to tell us how to live our lives. Mr Murphy's comments should alarm everyone and serve as evidence that loyalty card schemes are based on mass-scale surveillance of customers. Tesco has no right to make judgements about what's in our baskets or nudge us on what we should and should not be buying."
