This booklet constitutes the completely refereed court cases of the fee 2101 overseas Workshop, BIOID 2011, held in Brandenburg (Havel), Germany, in March 2011.
The 25 revised complete papers awarded have been conscientiously reviewed and chosen from various submissions and are accomplished through an creation on price. The papers are geared up in topical major sections on conception and platforms, handwriting authentication, speaker authentication, face acceptance, multibiometric authentication, and on biometrics and forensics.

Fears and Hopes for European Urbanization: Ten Prospective Papers and Three Evaluations

Urbanization is a strategy occurring in our society, that is altering from a predominantly rural and agrarian society right into a predominantly city and commercial one. it is a transformation which isn't simply happening in definite components, it isn't basically a focus of homes and of individuals and of actions, yet what's possibly even more very important: it's also a metamorphosis within the lifestyle.

Protecting Vulnerable Groups: The European Human Rights Framework

Inside of nearby and common foreign felony tools, the concept that of vulnerability has now not been definitively interpreted. This e-book analyzes the paintings of either the eu Union and the Council of Europe in ascertaining a transparent framework or a collection of standards compatible to figure out these teams which might be thought of susceptible and deprived, besides exploring the measures required to guard their human rights.

Sample text

Some important claims of Proposition 1 are listed below. If ξ + 2θ < 1, then the expected value of the metric in the Acc case is less than the expected value of the metric in the Rej case. The expected value of the metric in the Rej case is equal to 0 independently of p and ξ. If p ∈ {0, 1}, then the variances of the metric decrease as the function of 1/n when n increases. The variance of the metric in the Rej case is maximized when Q = Q, which means that the attacker uses the fair coin tossing strategy and never generates the ∗ symbols.

While the collision rate (CR) should be possibly low, the reproducibility rate (RR) should be possibly high. The biometric hash algorithm for dynamic handwriting (hereafter BioHash algorithm) has been described in [9] and aims to fulfill both requirements mentioned before, namely irreversible and robust hash generation, by means of user based quantization of feature values. Feature values are mapped to user-individual intervals resulting in the transformation of a feature vector to a vector of hash values.

If b is the vector containing the values of a randomly chosen vector B n = (B1 , . . , Bn ), then m(a, b) is also the value of a random variable m(a, B n ). By (11) and the specifications of the probabilistic ensemble used to generate the vector b in the Acc and the Rej cases, the probability distribution of m(a, B n ) is the binomial–type distribution determined by all possible collections k(a, b), a ∈ {0, 1}, b ∈ {0, ∗, 1} such that all entries belong to the set {0, . . , n} and k(0, 0) + k(0, ∗) + k(0, 1) = n(1 − p), k(1, 0) + k(1, ∗) + k(1, 1) = np.
