MULTI-TENANT CLOUD BASED SYSTEMS AND METHODS FOR SECURE SEMICONDUCTOR DESIGN-TO-RELEASE MANUFACTURING WORKFLOW AND DIGITAL RIGHTS MANAGEMENT

摘要

A multi-tenant cloud based system for secure scientific / engineering workflow and digital rights management includes (a) cloud tenant client machines configured such that non-display data storage and data export are disabled; and (b) a cloud environment providing for each cloud tenant: (1) a virtual desktop client machine management system; (2) a software defined network (SDN) based project isolation and security system; (3) a four-factor user login authentication system; (4) a role based user access, data control, and monitoring system; (5) a graph database in which scientific / engineering workflows are stored as workflow graph property models, (6) virtualized servers configurable to provide at least one workflow execution environment; (7) a graph based workflow execution tracking and compliance enforcement system; (8) a graph based digital rights management system configured for generating an intellectual property (IP) provenance pattern uniquely corresponding to IP consumed and/or produced in association with workflow execution; and (9) an encrypted backup system. Such a system can form portions of a virtualized design-to-release manufacturing (DTRM) system, such as a virtualized semiconductor DTRM system.
