We analyze and demonstrate the feasibility and superiority of linear optical single-qubit fingerprinting over its classical counterpart. For one-qubit fingerprinting of two-bit messages, we prepare "tetrahedral" qubit states experimentally and show that they meet the requirements for quantum fingerprinting to exceed the classical capability. We prove that shared entanglement permits 100% reliab...

Digital watermarking is a technique for embedding information in to cover media to prove ownership. It became very important in the number of application areas such as copyright protection, fingerprinting, broadcast monitoring, and medical application. During the last several years, various watermarking techniques have been proposed by different authors. Wavelet based watermarking is gaining mo...

O a clear night, anyone with a good telescope can see that the sky is strewn with thousands of satellites— some are manmade satellites, launched into orbit for communications and defense, and some are natural ones, such as our beloved Moon. However, there is another type of satellite that is much closer to home: the human genome is also littered with “satellites.” Genetic satellites are entirel...

objective(s):the utilization of molecular techniques in the epidemiology of tuberculosis have provided an opportunity for using effective markers to trace the transmission of the disease .the purpose of this study was to compare the genetic patterns of mycobacterium tuberculosis by three methods of rflp technique. materials and methods: in a cross-sectional and prospective study, 95 strains of ...

Code construction for digital fingerprinting, which is a copyright protection technique for multimedia, is considered. Digital fingerprinting should deter collusion attacks, where several fingerprinted copies of the same content are mixed to disturb their fingerprints. In this paper, we consider the averaging attack, which is known to be effective for multimedia fingerprinting with the spread s...

Under the application occasion of using data base as the soft products publication, there should be corresponding safety system, which could abstain the privacy actions from the betray users. A privacy tracing and solution resolution is raised in this thesis based on the digital fingerprinting relationship data base. Data fingerprinting database, which combined by patent watermarking and user’s...
