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...

Anonymity networks like Tor enable Internet users to browse the web anonymously. This helps citizens circumvent censorship from repressive governments, journalists communicate with anonymous sources or regular users to avoid tracking online. However, adversaries can try to identify anonymous users by deploying several attacks. One of such attacks is website fingerprinting. Website fingerprintin...

Progesterone is a mammalian gonadal hormone which generally present in plant samples trace amount. In the study, progesterone was identified ethanol extract of banana inflorescence Musa paradisiaca. L species by HPTLC method and silica part from plates were scrapped subjected to GC-MS analysis further confirms presence progesterone. Preliminary phytochemical evaluation, mineral content, fingerp...

sediment-related environmental problems pose a serious threat to sustainable land management in many developing countries, including iran. information regarding sediment sources represents a key requirement from the management perspective since identification of sediment sources is a precursor to the design of effective sediment management and control strategies. the fingerprinting approach has...

The aim of this paper is to develop a rapid, and highly sensitive quantitative HPLC fingerprint method with multiple indicators by using the Compound Chinese Medicine Wuwei Changyanning granule and 5 herbs in the prescription. The quantitative fingerprint chromatogram with multiple indicators was investigated. ⅰ)6 compositions included rutin, gallic acid, chlorogenic acid, atractylenolideⅠ, pac...
