  • A blind steganography method based on histograms on video files 
    Bayılmış, Cüneyt; Cakiroglu, M; Çakiroǧlu, Murat; Akar, Feyzi; Çetin, Özdemir (Maney Publishing, 2012)
    Several techniques of data embedding and data hiding have been proposed and developed especially during the last two decades due to continually increasing needs of secure communication. Still image, audio and video files ...
  • A New DCT Based Watermarking Method Using Luminance Component 
    Özcerit, Ahmet Turan; Yesilyurt, M; Yalman, Y (Kaunas Univ Technology, 2013)
    The main purpose of the digital watermarking is to provide information security and copyright protection. From this point of view, a robust blind watermarking method based on Discrete Cosine Transform for colour images is ...
  • A new feature encoding scheme for HIV-1 protease cleavage site prediction 
    Özcerit, Ahmet Turan; Gok, Murat (SPRINGER, 2013)
    HIV-1 protease has been the subject of intense research for deciphering HIV-1 virus replication process for decades. Knowledge of the substrate specificity of HIV-1 protease will enlighten the way of development of HIV-1 ...
  • A new steganography algorithm based on color histograms for data embedding into raw video streams 
    Çetin, Özdemir; Özcerit, Ahmet Turan (ELSEVIER ADVANCED TECHNOLOGY, 2009)
    Steganography, embedding secret data into unsuspected objects, has emerged as a significant sub-discipline of data-embedding methods. While mostly applied to still images in the past, it has become very popular for video ...
  • A Novel Chaotic System for Secure Communication Applications 
    Durdu, Ali; Özcerit, Ahmet Turan; Uyaroğlu, Yılmaz (KAUNAS UNIV TECHNOLOGY, 2015)
    The secure communication using synchronization between identical chaotic systems have been introduced in literature for a long time. A well-known practical application of chaotic synchronized systems is the Pecora and ...
  • A Robust Watermarking Method for Mpeg-4 Based on Kurtosis 
    Murat Yesilyurt; Yildiray Yalman; Özcerit, Ahmet Turan (OXFORD UNIV PRESS, 2015)
    Watermarking is a method of data hiding in relation to information security and copyright protection. In this paper, a new kurtosis-based watermarking approach is proposed for compressed video files. The proposed approach ...
  • Design and Evaluation of a New Security Method with Dynamic Channel Hopping For Jamming Attacks 
    Çakıroğlu, Murat; Özcerit, Ahmet Turan; Çetin, Özdemir (Gazi Univ, Fac Engineering Architecture, 2011)
    Wireless Sensor Networks (WSNs) are used in many fields such as military, medical, industrial applications since they provide several advantages like ease of use, lower installation cost, and flexibility. Their practical ...
  • Design and evaluation of a query-based jamming detection algorithm for wireless sensor networks 
    Çakıroğlu, Murat; Özcerit, Ahmet Turan (TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2011)
    Jamming attacks, which are the main cause of data corruption and network blockages in wireless sensor networks (WSNs), are one of the most serious threats for WSNs. This type of attack not only blocks the ongoing communication ...
  • OETMAP: a new feature encoding scheme for MHC class I binding prediction 
    Özcerit, Ahmet Turan; Gok, Murat (SPRINGER, 2012)
    Deciphering the understanding of T cell epitopes is critical for vaccine development. As recognition of specific peptides bound to Major histocompatibility complex (MHC) class I molecules, cytotoxic T cells are activated. ...
  • Prediction of MHC class I binding peptides with a new feature encoding technique 
    Özcerit, Ahmet Turan; Gok, Murat (Academic Press Inc Elsevier Science, 2012)
    The recognition of specific peptides, bound to major histocompatibility complex (MHC) class I molecules, is of particular importance to the robust identification of T-cell epitopes and thus the successful design of ...
  • The design and realization of a new high speed FPGA-based chaotic true random number generator 
    Ismail Koyuncu; Özcerit, Ahmet Turan (PERGAMON-ELSEVIER SCIENCE LTD, 2017)
    Chaotic systems and chaos-based applications have been commonly used in the fields of engineering recently. The most essential part of them is the chaotic oscillator that has very critical role in some applications such ...
