different technologies, provided that certain principles are being followed in the application of the technology. For example, the facial recognition technology may only be used for a specific purpose and only with consent of the individual. Interpretation of the law remains difficult, especially if there is an increase of new technologies. Since the law does not apply to every specific technology there is a chance that this technology can become a risk, because some technologies can violate the privacy of individuals.

ii. Misuse of personal data
Law enforcement agencies can use facial recognition technologies to identify criminals and criminal activity [21]. But there is no guarantee that the images and identities are safe. The data can be misused and when the data is shared, the individual’s privacy is gone. The misuse of the technology is one ethical aspect that needs to be concerned. The technology may gain unintended purposes. There have been numerous incidents in which video cameras were focused on inappropriate areas, for example on bedroom windows. Once it is determined that an individual’s face does not match with the database, the facial signature is supposed to be deleted. But there is no evidence that the identities are deleted. They can also be stockpiled, so they can be used in the future and can be shared among for instance other governmental agencies [21].

iii. Problem of error
The last ethical aspect to consider is the problem of error, which is the fact that incorrect matches can be made with face recognition technologies. This can lead to accusing innocent citizens. This is not always the fault of the technologies, but can occur in any database system with personal data. It would be acceptable to use facial recognition if a good ratio can be attained between false and true positive results. Provided that the individuals who are rated as a false positive are treated well and they are not questioned in an improper way. Peo
