In this study, the BOX-PCR fingerprinting technique was evaluated for the discrimination of clinical Pseudomonas aeruginosa isolates. All isolates were typeable and nearly half showed unique banding patterns. According to our results, BOX-PCR fingerprinting is applicable for typing of Pseudomonas aeruginosa isolates and can be considered a useful complementary tool for epidemiological studies o...

In recent years, content identification based on digital fingerprinting attracts a lot of attention in different emerging applications. In this paper, we perform the information–theoretic analysis of finite length digital fingerprinting systems. We show that the identification capacity over the Binary Symmetric Channel (BSC) is achievable by using Bounded Distance Decoder (BDD).

The fingerprinting technique consists in making the copies of a digital object unique by embedding a different set of marks in each copy. However, a coalition of dishonest users can create pirate copies that try to disguise their identities. We show how equidistant, binary codes that can be used as fingerprinting codes.

BACKGROUND We evaluated the efficacy of multilocus sequence typing (MLST) for assessing the genetic relationship among Candida albicans isolates from patients with candidemia in a hospital setting. METHODS A total of 45 C. albicans isolates from 21 patients with candidemia were analyzed. The MLST results were compared with results obtained by Southern blot hybridization (C1 fingerprinting) an...

This paper presents a perception oriented video fingerprinting technique based on the level of motion within the video. We describe and demonstrate the technique. The results show that motion detection can be used as the basis for fingerprinting of movie files.

We study blind fingerprinting, where the host sequence into which fingerprints are embedded is partially or completely unknown to the decoder. This problem relates to a multiuser version of the Gel’fand-Pinsker problem. The number of colluders and the collusion channel are unknown, and the colluders and the fingerprint embedder are subject to distortion constraints. We propose a conditionally c...

Classical fingerprinting associates with each string a shorter string (its fingerprint), such that any two distinct strings can be distinguished with small error by comparing their fingerprints alone. The fingerprints cannot be made exponentially smaller than the original strings unless the parties preparing the fingerprints have access to correlated random sources. We show that fingerprints co...

We test the predictive power of first-order reversal curve (FORC) diagrams using simulations of random magnets. In particular, we compute a histogram of the switching fields of the underlying microscopic switching units along the major hysteresis loop, and compare to the corresponding FORC diagram. We find qualitative agreement between the switching-field histogram and the FORC diagram, yet dif...

Passports issued nowadays have an embedded RFID chip that carries digitally signed biometric information. Access to this chip is wireless, which introduces a security risk, in that an attacker could access a person’s passport without the owner knowing. While there are measures in place to prevent unauthorised access to the data in the passport, we show that it is easy to remotely detect the pre...

DNA fingerprinting methods have evolved as major tools in fungal epidemiology. However, no single method has emerged as the method of choice, and some methods perform better than others at different levels of resolution. In this review, requirements for an effective DNA fingerprinting method are proposed and procedures are described for testing the efficacy of a method. In light of the proposed...
