SUPA: Strewn user-preserved authentication**

Objective – This paper presents the high level conceptual architecture of SUPA, an authentication system that would allow a system to authenticate users without having its own repository of users’ secret identification related data. Methodology/Technique – Central storage and management of user credentials or passwords leave a single tempting repository for the attackers. If the credentials are not stored by a system at all, there will be no stored ‘vault’ to allure the attackers. At the same time, there will be no single resource that holds the credentials of all users of a system. SUPA enables a system to authenticate itself users without having their secret credentials stored in it. Findings – The proposed authentication system uses the features of asymmetric encryption as part of its authentication process. Novelty – SUPA eliminates the requirement of secret user credentials at the system end, the user credentials are retained within the end-user’s devices

The Evaluation of Immigrants' Credentials: The Roles of Accreditation, Immigrant Race, and Evaluator Biases

Theories of subtle prejudice imply that personnel decision makers might inadvertently discriminate against immigrant employees, in particular immigrant employees form racial minority groups. The argument is that the ambiguities that are associated with immigrant status (e.g., quality of foreign credentials) release latent biases against minorities. Hence, upon removal of these ambiguities (e.g., recognition of foreign credentials as equivalent to local credentials), discrimination against immigrant employees from minority groups should no longer occur. Experimental research largely confirmed these arguments, showing that participants evaluated the credentials of black immigrant employees less favorably only when the participants harbored latent racial biases and the foreign credentials of the applicants had not been accredited. The results suggest the importance of the official recognition of foreign credentials for the fair treatment of immigrant employees.Labour Discrimination, Immigrants, Racial Minorities, Prejudice, Credential Recognition, Experiment

Managerial Valuation of Applicant Credentials and Personal Traits in Hiring Decisions

We study how managers value applicant credentials and personal traits in hiring decisions. Using the ordered probit model, we confirm previous results – managers rank applicant traits higher than credentials. However, we also uncover patterns not previously observed – managerial valuations of some of these characteristics are dependent on managers' perception of the overall state of the economy, on firm and immediate workplace characteristics, and on managers' personal characteristics. Manager valuations of credentials vary with a large number of factors; this is not so for applicant personal traits. This is not surprising as most managers view the five traits considered "as extremely important."personality, credentials, hiring practices, ordered probit

Privacy-Preserving Trust Management Mechanisms from Private Matching Schemes

Cryptographic primitives are essential for constructing privacy-preserving communication mechanisms. There are situations in which two parties that do not know each other need to exchange sensitive information on the Internet. Trust management mechanisms make use of digital credentials and certificates in order to establish trust among these strangers. We address the problem of choosing which credentials are exchanged. During this process, each party should learn no information about the preferences of the other party other than strictly required for trust establishment. We present a method to reach an agreement on the credentials to be exchanged that preserves the privacy of the parties. Our method is based on secure two-party computation protocols for set intersection. Namely, it is constructed from private matching schemes.Comment: The material in this paper will be presented in part at the 8th DPM International Workshop on Data Privacy Management (DPM 2013

Teacher Credentials and Student Achievement in High School: A Cross-Subject Analysis with Student Fixed Effects

We use data on statewide end-of-course tests in North Carolina to examine the relationship between teacher credentials and student achievement at the high school level. The availability of test scores in multiple subjects for each student permits us to estimate a model with student fixed effects, which helps minimize any bias associated with the non-random distribution of teachers and students among classrooms within schools. We find compelling evidence that teacher credentials affect student achievement in systematic ways and that the magnitudes are large enough to be policy relevant. As a result, the uneven distribution of teacher credentials by race and socio-economic status of high school students -- a pattern we also document -- contributes to achievement gaps in high school.
