Multimedia Security and Information Hiding With the fast development of Internet, the need to create, store and distribute the digital multimedia gets more and more increasing. This raises, however, security concerns since multimedia is highly vulnerable to the illegal copying, distribution, manipulations and other attacks. To remedy these security issues, the idea of “the digital watermarking” and “stenography” have been introduced where the secret information is carried over the host signal.For example, one can embed
In communication theory and technologies (CTT) group at Sabanci, which is supervised by Dr. Keskinoz, conduct research to develop practical and efficient algorithms for the multimedia and information hiding. Correlation Filter Pattern Recognition for Biometric Verification and Security Biometric person
identification and verification is a promising methodology for
authentication applications. However, there are many issues that need to
be addressed to ensure the security of biometric templates in biometric
authentication systems. One such aspect is the cancelability of a
biometric. For example, consider a scenario where a biometric template
is stored on a card for authenticating a user. What happens when that
card with the user’s biometric template is lost or stolen? How does one
cancel the lost or stolen card and re-issue a new biometric card for
that person? In order to protect the user’s biometric templates from
possible hacking and to ensure cancelability, the templates must be
encrypted. Then in case of theft or loss, a different encrypted
biometric template can be issued from the same original biometric
pattern. Recent work in using advanced correlation filters has shown
promise for biometric verification. Correlation filter methods offer
advantages such as shift-invariance and graceful degradation.
Supervised MS/PHD Theses:
A note for Prospective Graduate Students: The projects can be assigned to the new comers by Dr. Keskinoz. However, the project ideas suggested by the students are also welcome to keep the students motivated. For qualified and highly motivated individuals, assistantships can be provided.
