GENis, an open-source multi-tier forensic DNA information system

Abstract

GENis is an open source multi-tier information system developed to run a forensic DNA database at local, regional and national levels.11Fundación Sadosky holds all rights over GENis software and authorizes the publication of this article. It was conceived as a highly customizable system, enforcing several security policies including: data encryption, double factor identification, structure of user’s roles and permissions, system-wide secure log auditing, non-repudiation protocols and a blockchain-based option to reinforce genetic profile´s integrity. GENis is able to perform genetic profile queries of autosomal STR’s and its design follows ENFSI22European Network of Forensic Sciences Institutes. and ISFG33International Society of Forensic Genetics. standards and recommendations. In this work, we present a summary of GENis system design and architecture, the implemented matching rule definitions and the framework used to provide statistical significance to profile matches.
