Surprise, surpriseMr. Laporte and the panel of guests were discussing smartphone apps and why the apps were turning the microphone on. That certainly grabbed my attention. Especially, Mr. Laporte asking:
“Does it scare anybody we’ve learned that this program (referring to Color) turned on the microphone and was listening? Now, they’re not using it in any nefarious way.
But they didn’t have to tell us. They just did it. Doesn’t it mean that there may be many other apps that are doing the same thing? Doesn’t that bother anybody?”
I’ll get to this later. First, I want you to read what panel member, Robert Scoble points out:
“By the way it’s not the only app (Color) that uses the microphone. Shopkick uses the microphone to know when you entered the store. You turned on Shopkick and it’s actually listening for an inaudible signal.
So they have a speaker in front of Macy’s that when you take your iPhone inside Macy’s, inside the front door, it senses the audio signal and gives you points for entering the store.”
