What is Mel-Frequency Cepstral Coefficients

Chapter 12
Handbook of Research on Securing Cloud-Based Databases with Biometric Applications
In sound processing, the mel-frequency cepstrum (MFC) is a representation of the short-term power spectrum of a sound, based on a linear cosine transform of a log power spectrum on a nonlinear mel scale of frequency. Mel-frequency cepstral coefficients (MFCCs) are coefficients that collectively make up an MFC.

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.
