Fingerprint signature

To detect adulteration of wine. Bums et al. (2002) found that the ratios of acetylated to p-coumaroylated conjugates of nine characteristic anthocyanins served as useful parameters to determine grape cultivars for a type of wine. Our laboratory utilized mid-infrared spectroscopy combined with multivariate analysis to provide spectral signature profiles that allowed the chemically based classification of antho-cyanin-containing fruits juices and produced distinctive and reproducible chemical fingerprints, making it possible to discriminate different juices. " This new application of ATR-FTIR to detect adulteration in anthocyanin-containing juices and foods may be an effective and efficient method for manufacturers to assure product quality and authenticity. 

It is equally important for the manufacturer and regulator to know the level of additives in a polymer material to ensure that the product is fit for its intended purpose. Additive analysis marks sources of supply, provides a (total) process signature and may actually be used as a fingerprint of a polymeric material, in particular as molecular characterisation of the polymer... 

In a climax to his sediment studies, Patterson reported tersely that we have found the composition of lead in snow to be very different from the composition of lead which has been deposited on the ocean floors during the past 100,000 years. The lead in Lassen Volcanic National Park had a signature mix of lead isotopes, a characteristic fingerprint identifying it as a... 

This scheme is introduced in [4, 8], and also used in [7]. It differs from the basic scheme in the preprocessing and hiding operations. A secure hash function is applied to the signature before embedding, in order to reduce its size. The locations of the embedded CLBs are also fingerprinted with the identity of the user in order to trace back the origin of mis-appropriation. Additional hiding operations are also put in. 

Biometrics involves measuring the unique physical characteristics or traits of the human body. Any aspect of the body that is measurably different from person to person—for example, fingerprints or eye characteristics—can serve as a unique biometric identifier for that individual. Biometric systems recognizing fingerprints, palm shape, eyes, face, voice, and signature comprise the bulk of the current biometric systems. 

Cancer therapeutics — Different tumor types and the differentiated states of individual tumors are known to exhibit xmique gene expression patterns called molecular signatures or fingerprints. The molecular signature may be useful in tumor phenotype classification. 

Another aim of this study is to determine which elements are most reliable and useful for fingerprinting specularite and other heavy minerals commonly associated with it. Preliminary analyses and previous literature (5, 10, 11) indicate that transition metals (TM) and rare earth elements (REE) have unique signatures associated with genetic and metamorphic processes. This study will... 

A vibrational spectrum provides something like a structural fingerprint of matter because it is characteristic of chemical bonds in a specific molecule. Therefore, imaging based on vibrational spectroscopic signatures, such as Raman scattering and IR absorption, provides a great deal of molecular structural information about the target under study. 

An electrochemical flow detector, based on four working electrodes coated with different permselective film types, for use in flow-injection measurements of multiple nitroaromatic explosives was recently developed [18]. The resulting array response (Fig. 4) offers unique fingerprints of such explosive compounds. Electrochemical devices are extremely attractive for designing such e-nose-type multi-electrode arrays that combine several partially selective electrodes and lead to a distinct response pattern (signature) for mixtures of organic vapors without prior separation [2],...
