Teamwork: A Decentralized, Secure and Portable Team Management System

Abstract

We present Teamwork, an easy to use, portable system for team management. The distinguishing key feature of our solution is enhanced privacy provided by two means. First of all, all user content is moved from the cloud directly to users' devices, which share the data through a Peer-to-Peer overlay network for content distribution. Secondly, all content transferred through the network is secured in order to protect it from eavesdropping. Content is stored in files distributed through the Peer-to-Peer file system component named Teamshare.User's cognitive load is reduced by merging abstractions such as groups, organizations and projects into one simple concept -teams. The system is tightly integrated with existing mailing protocols, such that any task is an email.

Group Membership Management Framework for Decentralized Collaborative Systems

“…Teamwork [6] x MIDEP [14] x VO-Sec [12] x x Dec. access control model for dynamic collaboration [4] x x Decentralized access control for IoT [1,13] x x…”

“…For example, in [16], the authors propose a new approach to arranging collaboration in virtual organizations by using an enriched version of Git VCS that stores commit hashes using smart contracts and IPFS data storage, in order to securely manage authorship, system access privileges and licensing policies in a decentralized environment. Other ideas include for instance the Teamwork system [6] that stores the content at users' devices and provides a P2P overlay network for content distribution with enhanced privacy. The MIDEP [14] protocol offers public identity management for decentralized collaborative architectures that puts bigger focus on security and resistance to malicious attacks, without assuming any central point.…”

Use of Mobile Collaborative Tools for the Assessment of Out-of-Classroom Courses in Higher Education - Cloud Technologies Applied to the Monitoring of the Practicum

“…More recently, Asana (Asana, nd) has been developed as a teamwork tool for managing conversations and tasks in a more flexible way than simple e-mail exchange. As of today, there are dozens of different collaborative tools available, and their characteristics have been compared in many studies, e. g. Reixa et al (2012), Drȃghici et al (2013), etc.…”
