Re: Google the Good turning into Orwell's 1984
>> What details there are about this indicate that there is a conversion done on the PC that reduces the sound to a 4KB "fingerprint" and that the fingerprint can't be reverse engineered into the original sound.
So, how then can Google send targeted ads if they dont know what is said? The entire point of a targeted ad is that they pertain to what the conversation is about.
No matter how the fingerprint is represented (4-bytes according to google), it will be used as a lookup into a database to decipher what those 4-bytes represent. 4-bytes is enough storage to represent 4.3 billion different things. Whatever those things may represent is limitless in Google's databases.
To put this into perspective, a 4-byte fingerprint could easily represent the last 171,798 detected words in a conversation (based on a 25,000 word english vocabulary).
