Person de-identification upon primary biometric traits
 Šidó, Balázs ; Burget, Radim (referee) ; Přinosil, Jiří (advisor)
This bachelor’s thesis deals with various methods protecting privacy by de-identification based on the primary biometric traits. The first chapter describes face de-identification with ad-hoc, naive and advanced methods. It also describes the Active Appearance Models and the Active Shape Models. The second chapter consists of a general overview of voice signal processing and of voice de-identification methods by changing the levels of energy in each frequency band and by pitch shift. The following chapters are describing the realized face de-identification program and an algorithm design for reversible face de-identification using the appearance parameters of the Active Appearance Model. This is followed by algorithm designs for voice de-identification. The results of the experiments done with the de-identified pictures are introduced in the last chapter. The realized program were written in Matlab.
