Abstract
Cloud computing lacks control over physical and logical aspects of the system, which imposes profound changes in security and privacy procedure; hence, it needs a high level of security. Currently, many researchers and developments are being done to provide client service-level agreements regarding security issues. These researchers are attracted towards biometrics and its security applications, since it is based on biometric traits, thus providing a high level of security. Due to biometrics' benefits and cloud advantages, the collaboration of cloud and biometrics have open up wide areas this field. This chapter discusses some case studies of integration of biometrics and cloud computing.
