Stenotrophomonas maltophilia is a highly versatile species with useful biotechnological potential but also with pathogenic properties. In light of possible differences in virulence characteristics, knowledge about genomic subgroups is therefore desirable. Two different genotyping methods, rep-PCR fingerprinting and partial gyrB gene sequencing were used to elucidate S. maltophilia intraspecies ...

Coding methods for fingerprinting digital information are considered, with the aim of deterring users from copyright violation. A general model for discrete fingerprinting is presented, along with a simple embedding method for text documents. Different types of attacks are discussed, including attacks from colluding pirates. Some preliminary results are derived for random fingerprinting codes. ...

Finding trajectories and discovering motifs that are similar in large datasets is a central problem for a wide range of applications. Solutions addressing this problem usually rely on spatial indexing and on the computation of a similarity measure in polynomial time. Although effective in the context of sparse trajectory datasets, this approach is too expensive in the context of dense datasets,...

A watermarking scheme for distinguishing different copies of the same multimedia document (fingerprinting) is investigated. Efficient transmission of natural data requires lossy compression, which might impair the embedded watermark. We investigate whether the quantization step in compression schemes can be replaced by dithered quantization to combine fingerprinting and compression. Dithered qu...

Web tracking companies use device fingerprinting to distinguish the users of the websites by checking the numerous properties of their machines and web browsers. One way to protect the users’ privacy is to make them switch between different machine and browser configurations. We propose a formalisation of this privacy enforcement mechanism. We use information-theoretic channels to model the kno...

The present study was designed to evaluate the usefulness of two novel molecular typing methods, amplification of DNA fragments surrounding rare restriction sites (ADSRRS-fingerprinting) and the PCR melting profile (PCR MP), for Staphylococcus aureus strain differentiation. Thirty-seven S. aureus strains isolated from patients with a history of furunculosis were studied. The strains were identi...

Fingerprinting protocol applies a watermarking technique to embed a fingerprinting information in a digital content such as music, image, movie, etc.. The cryptographic protocol is studied by many researchers, but how to apply watermarking techniques is not remarked. In this paper, we study the problem to implement the watermarking techniques in the fingerprinting protocol, and then propose an ...

Including a unique code in each copy of a distributed document is an effective way of fighting intellectual piracy. Codes designed for this purpose that are secure against collusion attacks are called fingerprinting codes. In this paper we consider fingerprinting with the marking assumption and design codes that achieve much higher rates than previous constructions. We conjecture that these cod...
