9,135,430, "Digital rights management system and method," assigned to Rockwell Automation Technologies, Inc.
The present invention concerns application of digital rights management to industrial automation devices including programmable logic controllers (PLCs), I/O devices, and communication adapters. Digital rights management involves a set of technologies for controlling and managing access to device objects and/or programs such as ladder logic programs. Access to automation device objects and/or programs can be managed by downloading rules of use that define user privileges with respect to automation devices and utilizing digital certificates, among other things, to verify the identity of a user desiring to interact with device programs, for example. Furthermore, the present invention provides for secure transmission of messages to and amongst automation devices utilizing public key cryptography associated with digital certificates.
9,135,410, "Digital rights management using a digital agent," assigned to AT&T.
A method for digital rights management includes a digital agent for contacting a media host. Media content is compared to a user profile and an identification confidence level is assigned to the media based on the comparison. A digital agent contacts a host of the media based on the identification confidence level, the type of media, and the context of the media. The digital agent requests one or more actions of a media host based on user designations concerning information related to the media. The identification confidence level is generated based on a plurality of user characteristic confidence levels which are generated based on media being analyzed.
