The retail sector needs to resolve the problem of the frequent thefts that take place in shops. This type of crime is characterized by the fact that it is usually the same people who repeatedly commit these infringements. Consequently, having a system at their disposal that makes it possible to identify this type of subject in the most vulnerable places ends up being fundamental to avoid frequent thefts. The existence of databases with the faces of recurring offenders can help to resolve this problem.
On the other hand, there is also a growing interest in identifying the typology of the clients of a certain business. Systems of facial marketing permit the analysis of visitors’ faces providing demographic data that makes it possible to establish the profiles of habitual clients.
