I'd like to build an app for single and poly people to rate dates and individuals based on their behavior and to also use their biometrix, NFC tags or QR codes to consent to sex. A rating will build up a social and sexual profile which will help infer dating decisions and hopefully rule out ambiguous claims where it is thought that this approach is aiding the perpetrator, more than protecting. in my opinion, the minute you meet your date, the phone is in listening mode which both parties are aware of and will act as proof/evidence should it be needed. Can the data make predictions and form opinions or predictions of a misjustice/criminal likelihood? Can we use data sets such as ratings, like trust pilot also? Building up a character score?
