Sample Solution

Abstract – This paper studies the use of facial recognition technologies to prevent crime. The most common technologies that are being used for security and authentication purposes are analyzed. The Eigenface method is the most used facial recognition technology, it can be used for security and authentication purposes. This method focuses on the aspects of the face stimuli that are important for identification, this is done by decoding face images into significant local and global ‘features’.
There are many ways for law enforcement to help them in decreasing the amount of crime. Four of these ways that use facial recognition are: FaceIt, matching faces from live security images, face recognition in photographs and face recognition from sketches. As these technologies are improving very rapidly, the dangers and ethical issues also have to be taken into account before the technologies can actually be used in our daily lives.
From this paper can be concluded that facial recognition creates a lot of opportunities to help prevent crime. However, there are still a lot of difficulties that can cause problems when these techniques are used in the real world.
