Biometric authentication, which requires storage of biometric templates and/or encryption keys, raises a matter of serious concern, since the compromise of templates or keys necessarily compromises the information secured by those keys. To address such concerns, efforts based on dynamic key generation directly from the biometrics have recently emerged. However, previous methods often have quite unacceptable authentication performance and/or small key spaces and therefore are not viable in practice. The purpose of this paper is to propose a novel method which can reliably generate long keys while requires storage of neither biometric templates nor encryption keys.

This proposition is achieved by devising the use of fingerprint orientation fields for key generation. Additionally, the keys produced are not permanently linked to the orientation fields, hence, allowing them to be replaced in the event of key compromise.

The evaluation demonstrates that the proposed method for dynamic key generation can offer both good reliability and security in practice, and outperforms other related methods.

This paper aims to investigate the importance and prevalence of Guanxi in business interactions in network-based societies such as China, few studies have the phenomenon from a dyadic view. In a business dyad, one partner may not value Guanxi and take it as a template for actions as the other does.

The authors propose that such collective and asymmetric Guanxi orientation influence both the creation and distribution of relational rent in a Guanxi dyad. Furthermore, relationship-specific investments (RSIs) moderate the relationship between dyadic Guanxi orientation and relational rent creation and distribution.

Based on a matched sample of supplier-buyer dyads in China, the authors find that joint Guanxi orientation is positively related to joint pie creation, whereas Guanxi orientation imbalance has a positive effect on the pie distribution imbalance.

These results contribute to the literature by revealing how dyadic Guanxi dynamics and practices affect dyadic performance and providing managers with meaningful implications for dyadic Guanxi management.
