By now, we have all heard about facial recognition technology and how it is becoming more commonplace in our everyday lives. But do you really know how it works and its benefits?
Facial recognition technology (FRT) analyzes the unique features of a person’s face to verify their identity. This advanced technology can be used as identification authentication to protect sensitive areas or information. As this technology continues to advance, we will see an increase in reliability and application.
Learn more about the different types of FRT:
Traditional FRT uses a photo or image of a face to analyze the basic geometry of the features. After analyzing, the features are cross-referenced against a database of different faces.
- 3-Dimensional (3D)
A more sophisticated technology, 3D FRT uses 3D sensors and cameras at various angles. The 3D sensors capture the shape and contours of the face, while cameras capture traditional FRT data. Both data sets are merged to create a comprehensive understanding of the face, including different facial expressions. Then this data is cross-referenced with the database.
- Surface Texture Analysis
Surface Texture Analysis takes an image of a patch of skin (also known as a skin print). The skin print is then segmented and turned into measurable space with complex algorithms. It is then analyzed for any lines, pores, or interesting characteristics. This technology is used in tandem with traditional and 3D FRT and can distinguish between identical twins.
Thermal FRT uses more advanced cameras, but has the same basic concept as other FRT. This technology uses both traditional and thermal cameras to create facial recognition in low visibility scenarios.
As you can imagine, all the different types of FRT can be used to ensure heightened security in places housing highly sensitive data as well as keeping unknown persons away from private property. Share your own thoughts about FRT and its future with us on Facebook, Twitter, LinkedIn, and Pinterest.
