Chanel Hair Studio is a busy high-end hair salon. In an effort to maximize efficiency of its operations and reduce wait times for appointments, Chanel decides to implement artificial intelligence software that will use client profiles and history to predict which clients will likely be late for their appointments. Information used to create the client profile included appointment history, distance from the salon, and any references to being tardy pulled from the client's social media accounts. If a client is predicted to be late, their appointment will be cancelled within 5 minutes.
Based on the details, what is the biggest potential privacy concern related to Chanel's use of this new software?
