Agroforestry generally contributes to rural food and nutrition security (FNS). However, specialization on commodity-oriented agroforestry practices or management strategies can weaken local sourcing when terms of trade fluctuate, as is the case coffee in Ethiopia. Hence, this study assessed trade-offs that smallholder farming households south-western Ethiopia face between growing systems their ...

Biometrics is the science and technology of measuring and analyzing biological data of human body, extracting a feature set from the acquired data, and comparing this set against to the template set in the database. Experimental studies show that Unimodal biometric systems had many disadvantages regarding performance and accuracy. Multimodal biometric systems perform better than unimodal biomet...

Biometrics based personal identification is regarded as an effective method for automatically recognizing a person’s identity with confidence. A multimodal biometric system consolidates the evidence presented by multiple biometric sources and typically better recognition performance compare to systems based on a single biometric modality. This paper proposes a novel multipartite algorithm for s...

Biometric authentication is used to secure digital or physical access. Such an system uses a biometric database, where data are sometimes protected by cancelable transformations. This paper introduces the notion of masterkeys. A masterkey feature vector such that corresponding template matches with significant number templates stored in database. directly researched from but we also investigate...

The rapid development of biometric hardware and software, and the increased use of biometrics in identity management led to the appearance of the problem of interoperability of biometric systems as well as security of biometric information that is transmitted over the network. This paper analyzes the solution to the problem of security of biometric data transactions via network by implementing ...

Biometric performance improvement is a challenging task. In this paper, a hierarchical strategy fusion based on multimodal biometric system is presented. This strategy relies on a combination of several biometric traits using a multi-level biometric fusion hierarchy. The multi-level biometric fusion includes a pre-classification fusion with optimal feature selection and a post-classification fu...

A biometric system provides automatic recognition of an individual based on a unique feature or characteristic possessed by the individual. These biometric characteristic may physiological or behavioral. Unlike other identification methods such as id proof, tokens and password, the distinct aspect of biometric recognition comes into light from randomly distributed features in human being. In th...

Biometric security is a fast growing area. Protecting biometric data is very important since it can be misused by attackers. In order to increase security of biometric data there are different methods in which watermarking is widely accepted. A more acceptable, new important development in this area is reversible watermarking in which the original image can be completely restored and the waterm...
