Abstract

A software object authorization system includes the ability to select signers who must approve a software object before it is downloaded to a process control system. The signers are presented with a form allowing them to authenticate their identity with a username and a password. Signers that have authenticated their identity may approve or reject the software object. A software object is authorized when all approvals needed for that software object have been received. Authorized software objects may then be downloaded to the process control system.
