Privacy preserving and robust watermarking on sequential genome data using belief propagation and local differential privacy
(Bilkent University, 2020-08)Genome data is a subject of study for both biology and computer science since the start of Human Genome Project in 1990. Since then, genome sequencing for medical and social purposes becomes more and more available and ... -
Privacy-preserving computation and robust watermarking techniques for healthcare data
(Bilkent University, 2018-07)Health and genomic data is sensitive in terms of carrying private information about individuals. One can infer inherited/genetic disorders, their occurrence probabilities, information about race, and kinship by analyzing ... -
Watermarking based on discrete wavelet transform and q-deformed chaotic map
(Elsevier Ltd, 2017)Hierarchy of one-dimensional ergodic chaotic maps with Tsallis type of q-deformation are studied. We find that in the chaotic region, these maps with q-deformation are ergodic as the Birkhoff ergodic theorem predicts. ... -
Watermarking via zero assigned filter banks
(Elsevier, 2009-07-17)In order to identify the owner and distributor of digital data, a watermarking scheme in frequency domain for multimedia files is proposed. The scheme satisfies the imperceptibility and persistence requirements and it is ... -
Watermarking via zero assigned filter banks
(Bilkent University, 2005)A watermarking scheme for audio and image files is proposed based on wavelet decomposition via zero assigned filter banks. Zero assigned filter banks are perfect reconstruction, conjugate quadrature mirror filter banks ...
