Your personal data: That’s what Windows 10’s Hello and Cortana features need to help you, assuming you’re comfortable with that.
To be fair, it’s nothing new—plenty of apps and services ask for your preferences, location, etc., to serve you better. Windows Insiders who opted in to the Windows 10 Technical Previews have already given Microsoft quite a bit of carte blanche in the spirit of improving its services. But Windows 10’s efforts to get to know you—and tie you into its services—will be a new experience for those of you upgrading or buying new Windows 10 PCs.
The Hello authentication feature and the Cortana digital assistant are particularly inquisitive, seeking to know your face and your preferences in detail. Windows Hello isn’t an issue for most of us, however, because its required camera technology will only be found in new PCs, and a very limited number of them. Microsoft’s digital assistant, Cortana, will be more ubiquitous, especially if you use her to help answer questions and perform simple tasks.
Here’s what to expect from Cortana and Hello if you use them in Windows 10.
Cortana: She’s listening
One of the first things Microsoft would like you to do after turning on your new Windows 10 PC is to set up Cortana, Microsoft’s digital assistant. Cortana can be a valuable assistant, answering quick questions—either spoken or typed—and setting reminders, playing music, and a host of other tasks.
Keep in mind, however, that whatever data you give Cortana, stays with Cortana. And Cortana wants everything: “your device location, data from your calendar, the apps you use, data from your emails and text messages, who you call, your contacts and how often you interact with them on your device,” according to Microsoft. “Cortana also learns about you by collecting data about how you use your device and other Microsoft services, such as your music, alarm settings, whether the lock screen is on, what you view and purchase, your browse and Bing search history, and more.”
Microsoft portrays all this data-gathering as beneficial. For example, any favorite teams you specify in the MSN Sports app will be showcased in the Cortana summary screen. Some benefits are less obvious: Choosing to sign into Facebook within Cortana allows Microsoft to access certain Facebook information so that Cortana and Bing can give you more personalized recommendations, according to Microsoft.
How do you keep track of Cortana? A couple of ways. First, you can use the Notebook within Cortana to specify what you’d like to see. Click the Cortana “Ask me anything” bar, then the Notebook icon (the little square with a hole through it, three icons down). This allows you to pick your favorite activities.
Here’s where it gets a little tricky. If you lock your PC and walk away from it (or it locks automatically after a certain period of sitting unattended) the Hello depth camera will constantly scan the room.
“The camera sensor is based on infrared technology, so it’s looking for shading and light refraction,” according to a Microsoft spokeswoman, in an email. “It is looking for images in IR that look like a human face. Once it finds a face, it identifies landmark locations such as eyes, nose, etc. It uses those landmark points as a reference location to analyze the shading and light intensity around them to differentiate you from someone else.”
Does that mean you’ve just introduced a Windows 10 spy camera into your office? Microsoft says no. However, the camera is “always on when the lock screen is active,” she added. “The camera turns off when the user is authenticated and transitioned to the desktop or when the screen turns off due to power settings/screen saver.”
Here’s what Microsoft’s privacy statement says about Hello: “If you turn it on, Windows Hello uses your face, fingerprint or iris to identify you based on a set of unique points or features that are extracted from the image and stored on your device as a template—but it does not store the actual picture or image of your face or iris. Biometric verification data that’s used when you sign in doesn’t leave your device. You can delete your biometric verification data from within Settings.”
Watching and learning
Hello isn’t a privacy risk, per se, but rather a different way of interacting with your PC, with the new idea that it’s actually watching you—or rather, watching for you. If any of this worries you, you can turn off Hello. The easiest way is to go into the Start menu, enter the Settings, then type in “Hello” into the search box. You’ll probably be directed to a screen where you can set up your Windows login information, including Hello.
Microsoft has already weathered a period where gamers worried that the Xbox One’s Kinect camera would be snapping pictures of them in their underwear. Now it’s the PC’s turn. When it comes to privacy, Windows Hello and Cortana just scratch the surface of the information you’re providing to Microsoft. Check out the rest of the privacy statement for more.
