Ah, I thought they did this to know what people are watching. Yes... see here:
> Alphonso's software uses the same technology that Shazam and similar services employ to automatically detect the song you're listening to. It samples small bits of audio, creating a digital "fingerprint" of it, and comparing it against a a database on their server to identify the show or movie. In fact, Alphonso's CEO says they have a deal with Shazam, and use their specific technology to do this. But this embedded software can even be listening even when your phone's screen is turned off and it's ostensibly idle.
I worked at Alphonso, and yes their tech also used small fingerprints made of small bits of audios. But they primarily used it in TV's to figure out what ads people are watching and then used that data for retargeting users on digital platforms.
