No it won't. Apple clearly states that not every scan is used to train the network. If the neural network determines that the picture is not of good quality, then it simply will be rejected. A neural network needs training, and it clearly wasn't offered in this case. It will probably be much harder for his brother to access his phone after the first 100 scans or so.Nope. For the machine to learn from this it would need some feedback loop to tell it that it made an incorrect identification. That feedback doesn't exist so it will most likely keep on doing this.
