After a few clicks, we were staring at neighborhoods in Nigeria that had been overtaken by the extremist group Boko Haram. A few more clicks and the image was even more familiar: my neighborhood in Washington, D.
Andy Wild, the chief revenue officer, spoke of the new frontier in a slightly quavering voice. I was pondering the implications of this when a young woman showed me what was on her laptop.
So it had asked Planet to provide satellite imagery of homes in Plano, Texas. Neligh shrugged and offered a thin smile. Now her client had the truth. What would it do with this information?
Conduct a surprise raid on the somnolent hamlets of Plano? Jack up premiums? Order images that might show construction crews installing new Jacuzzis and Spanish tile roofs? The future is here, and in it, truth is more than a kindly educator. It is a weapon—against timber poachers and burglars and mad bombers and acts of God, but also against the lesser angels of our nature.
People lie, you know. The age of transparency is upon us. As I walked back to my hotel, I thought about the two moped riders in Islington, as I often had in the months since I surveilled them. I wondered if they had been arrested. I wondered if they were guilty of anything at all, apart from the crime of being conspicuously interesting on an otherwise dull morning.
I wondered if they would ever know that unseen strangers had been watching them, just as a stranger might now be watching me—someone somewhere squinting into a CCTV monitor at the spectacle of a lone figure walking fast on a dark and otherwise vacant street on a chilly night without a coat on, as if in flight from something. They Are Watching You—and Everything Else on the Planet Technology and our increasing demand for security have put us all under surveillance.
Is privacy becoming just a memory? By Robert Draper. This story appears in the February issue of National Geographic magazine. Sal radios the police station. Photograph by Toby Smith. London authorities were early adopters of widespread closed-circuit television CCTV surveillance after the city was targeted by terrorists using truck bombs in the early s. From to the city saw a 72 percent increase in cameras, making up one-third of the U.
Today Londoners are some of the most closely watched city dwellers in the world; as one example, the borough of Islington, just north of central London, monitors cameras.

When patterns start to resemble the model, the system signals it has homed in on a face. Personal devices. Smartphones use face recognition for apps and security, such as unlocking the phone. Checkpoint cameras.
Faces are recorded at customs and security checkpoints, and the images are archived. Other cameras. Laptop, video, and thermal cameras used in some security systems can capture face images. CCTV cameras. Systems can isolate and track individuals by face, gait, and clothing color and pattern. Face imagery captured when a person poses for the camera, such as at security checkpoints, is easier to analyze; imagery captured from CCTV cameras may require advanced methods and detailed analysis.
Algorithms build more informative and accurate digital representations—called face templates—using thermal, geometric, and other data, either separately or combined. Spatial relationships between facial features, such as the center of the eyes and tip of the nose, are calculated. Algorithms can build a face even if an image is obscured by poor lighting or distorted by odd angles or expressions. Skin-texture analysis. Pores, wrinkles, and spots are mapped and analyzed; the technology can even differentiate between twins. Thermal sensors. This technology can provide further informa- tion despite obstacles such as heavy makeup or disguises.

In the s the U. Army Corps of Engineers built more than concrete crosses, 60 feet wide, in the Arizona desert. To create the image above, two artists photographed the cross, tracked the trajectories of satellites that pass overhead, and drew arcs in the sky showing their paths. Photograph by Julie and Damon Sauer. More than 1, satellites orbit above us, some as much as , miles overhead.
They collect images and other data, broadcast information, track our locations, and even listen to our conversations.

Navigation, timing, and tracking Track ships, aid navigation, and synchronize timing for computer systems.

Other satellites About 60 countries operate the remaining satellites in orbit. Jason Treat and Ryan T. Sources: Union of Concerned Scientists; Planet. Three telescopes of the Deimos Sky Survey, based in Spain, watch for close asteroids and man-made space debris that could damage satellites, as an airplane streaks across the sky.

In a pilot program at the Port of Boston, scientists and engineers have designed an advanced scanner that can identify the molecular makeup of substances with far more specificity than ever before, quickly differentiating, for example, between salt and cocaine. As the 3-D model is being created, a detector scans the cargo for neutrons, produced when x-rays interact with nuclear material.
When the data are combined with the 3-D model, an operator can pinpoint the location of any nuclear contraband.

The truck and its contents are identified by four categories below based on average atomic number the number of protons. To avoid harmful doses of radiation, the driver pulls into the scanner, parks, and exits before the truck is sent through the system. Density of material. Zinc and heavier. Atomic number.

Algorithms then analyze the 3-D model for atomic numbers and densities that could indicate contraband, such as explosives and drugs. Energy from nuclear fluorescence. Imaging with X-Rays. Americans had more confidence in other institutions, such as cellphone manufacturers and credit card companies, to protect their data. The Snowden revelations were followed in the ensuing months and years with accounts of major data breaches affecting the government and commercial firms.
