  - JOURNAL OF MICROBIOLOGICAL METHODS - Rok 2007

  W pracy pokazano użyteczność dwóch nowych metod do typowania molekularnego Staphylococcus aureus, ADSRRS-fingerprinting (Amplification of DNA fragments Surrounding Rare Restriction Sites) i PCR MP (PCR melting profile). Przebadano 37 szczepów Staphylococcus aureus izolowanych od pacjentów z czyracznością. Jako metodę referencyjną zastosowano REA-PFGE. Okazało się, że izolaty Staphylococcus aureus z nosa od niektórych pacjentów...

  Psoriasis is a multifactorial disease in which genetic, environmental and epigenetic factors regulating gene expression play a key role. In the “genomic era”, genome-wide association studies together with target genotyping platforms performed in different ethnic populations have found more than 50 genetic susceptible markers associated with the risk of psoriasis which have been identified so far. Up till now, the strongest association...

• Digital Fingerprinting based on Quaternion Encryption for Image Transmission

  Publikacja

  • B. Czaplewski
  • M. Dzwonkowski
  • R. Rykaczewski

  - Przegląd Telekomunikacyjny + Wiadomości Telekomunikacyjne - Rok 2013

  In this paper a new digital fingerprinting scheme for images is proposed. A proposed method is based on quaternion encryption with Cipher Block Chaining (CBC) mode of operation. Quaternions are hyper-complex numbers of rank 4 and thus often applied to mechanics in three-dimensional space. The encryption algorithm is designed for grey-tone images. For purpose of encryption, the algorithm uses the rotation of data vectors presented...

• Digital fingerprinting for color images based on the quaternion encryption scheme

  • M. Dzwonkowski
  • R. Rykaczewski

  - PATTERN RECOGNITION LETTERS - Rok 2014

  In this paper we present a new quaternion-based encryption technique for color images. In the proposed encryption method, images are written as quaternions and are rotated in a three-dimensional space around another quaternion, which is an encryption key. The encryption process uses the cipher block chaining (CBC) mode. Further, this paper shows that our encryption algorithm enables digital fingerprinting as an additional feature....

• Receiver-side fingerprinting method based on quaternion sandwich product

  Publikacja

  • B. Czaplewski
  • R. Rykaczewski

  - Przegląd Telekomunikacyjny + Wiadomości Telekomunikacyjne - Rok 2014

  In this paper a new receiver-side fingerprinting method for color images is proposed. The proposed method belongs to the group of Joint Fingerprinting and Decryption (JFD) methods. Each component of the color image is represented as a point in 3D space, which is formed by 3 color channels. Encryption and fingerprinting can be interpreted as rotation, scaling and translation of these points. Calculations are performed using quaternion...

• Digital Fingerprinting Based on Quaternion Encryption Scheme for Gray-Tone Images

  Publikacja

  • B. Czaplewski
  • M. Dzwonkowski
  • R. Rykaczewski

  - Journal of Telecommunications and Information Technology - Rok 2014

  In this paper a new idea of digital images fingerprinting is proposed. The method is based on quaternion encryption in the Cipher Block Chaining (CBC) mode. Quaternion sare hyper-complex numbers of rank 4 and thus often applied to mechanics in three-dimensional space. The encryption algorithm described in the paper is designed for gray-tone images but can easily be adopted for color ones. For the encryption purpose, the algorithm...

• Improvement of Fingerprinting Method based on Hill Cipher by using Frequency Domain

  Publikacja

  • B. Czaplewski
  • R. Rykaczewski

  - Rok 2012

  The main goal of this paper is to present the advantages of a digital fingerprinting in a frequency domain over a pixel domain, in case of VoD services (Video on Demand). The paper presents basic issues of a multimedia data protection by digital fingerprinting. It also describes threats to embedded fingerprints from both collusion attacks and from a transmission itself. Possible solution was presented on the example of the DCT...
