Food authenticity studies are concerned with determining if food samples have been correctly labeled or not. Discriminant analysis methods are an integral part of the methodology for food authentication. Motivated by food authenticity applications, a model-based discriminant analysis method that includes variable selection is presented. The discriminant analysis model is fitted in a semi-superv...

Determining the authenticity of public keys in large-scale open networks can not be based on certiicates alone, but must also include the binding between the key used for certiication and it's owner, as well as the trust relationships between individual agents. This paper describes a method for computing authenticity measures based on certiicates, on key binding, and on trust relationships. Two...

This paper analyses the shift from constructivist to existentialist conceptions of authenticity in tourism. I argue that the existentialist approach represents a withdrawal from an ongoing and unresolved debate, rather than the reconciliation that it has sometimes been presented as. Such an approach has divorced the notion of authenticity from any inherent relationship to the act of touring. Ut...

This article examines the Mu‘tazilite Qādī ‘Abd al-Jabbār’s views on the denotation of miracles according to his own particular methodology. Despite his acceptance of the celebrated method of the theologians in the denotation of miracles with respect to the authenticity of prophets, i.e., resorting to divine wisdom, Qādī ‘Abd al-Jabbār instead proposed the issue within the structure of conven...

BACKGROUND This work deals with copyright protection of digital images, an issue that needs protection of intellectual property rights. It is an important issue with a large number of medical images interchanged on the Internet every day. So, it is a challenging task to ensure the integrity of received images as well as authenticity. Digital watermarking techniques have been proposed as valid s...

We make the case for an emergent notion of authenticity of science based on systems theory and neo-Piagetian thought. We propose that authentic science is an emergent property of a dynamic system of learning precipitated by the interactions among students, teachers, and scientists that occur within the contexts defined by the internal and external constraints of the cultures of the schools and ...

We study homomorphic authenticated encryption, where privacy and authenticity of data are protected simultaneously. We define homomorphic versions of various security notions for privacy and authenticity, and investigate relations between them. In particular, we show that it is possible to give a natural definition of IND-CCA for homomorphic authenticated encryption, unlike the case of homomorp...

This study examined the within-person relationships among daily self-esteem, felt authenticity (i.e., the operation of one's "true self"), and satisfaction of psychological needs for autonomy, competence, and relatedness. We also included measures of affect to control for the variance these constructs might share with affect. Over a 2-week period, 116 participants responded daily to measures of...

Authenticity is a difficult and taxing notion in both the digital and the analogue world. It is a retrospective and by implication dynamic notion, a reaction to whether or not we are dealing with the genuine article, that an object is what it purports to be at a moment in time and its content can be validated using available technology. It is not an end in itself like a fresh herring, but a red...
