What does the film predict about surveillance in the future?

In the future of Minority Report, people are identified by their eyes. Whenever anyone comes into a building, cameras scan individuals' eyes to confirm their identities. While this is an efficient mode of identification in the futuristic society of the film, it's also an invasive form of surveillance. Surveillance, in the film, is not only connected to organizations knowing where people are, but also to how corporations advertise and target consumers. When people enter stores, holograms of salespeople begin talking to them by name, referencing previous purchases and trying to appeal to them through highly personalized assistance.
