5.1 WIDESPREAD SOCIAL MEDIA ADOPTION e use of the Internet and social media has become pervasive in all aspects of our global society. Social media is a new frontier applicable to virtually all walks of life. Its use and operation is relevant globally to individuals, technology providers, governments, criminals, terrorists, and professionals such as social scientists, scientic researchers, salespersons, publishers, and entertainers. We are embracing an exciting new era of the unknown. Personal identication and identity verication have become that much more important because we human beings have lost a fundamental element of social activity through physical interaction. Much of what we do is now virtual via remote electronic interaction. As users of the Internet and social media, we want secure and reliable identity techniques that ensure privacy, secure nancial transactions, and authenticate social media users. Biometric identication technologies have their roots in law enforcement applications. However, with the increasing need to ght global terrorism and the availability of more powerful and lower cost computing platforms and new sensor technologies, biometrics have become more reliable and commoditized. Biometric identication technologies oer the ability to reliably verify or determine the identity of individuals both in person and online. is chapter will focus on the application of biometrics for the purposes of identity authentication and data mining. Specically, this chapter will discuss that biometric technologies can facilitate data mining in various web and social media applications (e.g., business/marketing and law enforcement/intelligence); how biometric technologies incorporated into social media applications can enhance the utility of the applications (e.g., face recognition that can be used to help search for a desired photo in a photo library); and how biometric technologies can be applied to assure user identity (security).
