Digital fingerprinting of multimedia data involves embedding information in the content, and offers protection to the digital rights of the content by allowing illegitimate usage of the content to be identified by authorized parties. One potential threat to fingerprints is collusion, whereby a group of adversaries combine their in&vidual copies in an attempt to remove the underlying fingerprint...

Recently, many studies of indoor positioning system using wireless signals such as WiFi, Bluetooth, have been researched actively. There are three types of indoor positioning system, triangulation method, fingerprinting technique and Cell-ID technique. Triangulation method has advantages in searching locations in wide environment, but its accuracy deteriorates in narrow indoor environment due t...

Digital fingerprinting schemes are cryptographic methods deterring buyers from illegally redistributing digital contents. It enables sellers to identify the traitor by providing each buyer with a slight different version. What is important in designing fingerprinting scheme is to make it more practical and efficient. Recently, two oblivious transfer protocolbased schemes to consider practicalit...

this contribution determines suitable fingerprinting properties for sediment source discrimination within theamrovan and atary catchments in semnan province, iran. these catchments are representative of a range of geology formations and should therefore provide a meaningful basis for a general assessment of the degree of sediment source discrimination afforded by a range of fingerprint properti...

background and objectives: the escherichia coli strains are greatly important in nosocomial and community acquired infections. the aim of this study was to determine the transmission of bacterial infections using genetic analysis. materials and methods: two hundred and thirty escherichia coli strains, isolated from different clinical samples, were characterized by enterobacterial repetitive int...

This paper is the result of a two month research internship on the topic of library version identification. In this paper, ideas and techniques from literature in the area of binary comparison and fingerprinting are outlined and applied to the problem of (version) identification of shared libraries and of libraries within statically linked binary executables. Six comparison techniques are chose...

Digital fingerprinting is an emerging technology to protect multimedia from unauthorized use by embedding a unique fingerprint signal into each user’s copy. A robust embedding algorithm is an important building block in order to make the fingerprint resilient to various distortions and collusion attacks. Spread spectrum embedding has been widely used for multimedia fingerprinting. In this paper...

Flow fingerprinting is a mechanism for linking obfuscated network flows at large scale. In this paper, we introduce the first blind flow fingerprinting system called TagIt. Our system works by modulating fingerprint signals into the timing patterns of network flows through slightly delaying packets into secret time intervals only known to the fingerprinting parties. We design TagIt to to enable...

Research that began a decade ago in video copy detection has developed into a technology known as “video fingerprinting”. Today, video fingerprinting is an essential and enabling tool adopted by the industry for video content identification and management in online video distribution. This paper provides a comprehensive review of video fingerprinting technology and its applications in identifyi...
