Patent number: 8875222Abstract: A highly efficient access control system and method employing XACML standard based policies and rules provides high performance resource access control of information systems of large enterprises. The system and method extracts plain rules from the XACML policies, transforms the plain rules into atomic rules, and compresses and indexes the atomic rules for fast lookup and retrieval. Access requests are decomposed into atomic requests which are compressed using the same value mapping as the rules. Index keys derived from compressed atomic request triplets are used to look up applicable rules which are used to evaluate requests for access to information system resources.Type: GrantFiled: June 30, 2011Date of Patent: October 28, 2014Assignee: EMC CorporationInventors: Lei Chang, Jeroen Van Rotterdam, David Choy

Patent number: 8568356Abstract: A communication device (CD) exchanges messages with an implantable infusion pump via telemetry such that commands are supplied thereto and operational information is obtained therefrom. The CD is controlled, at least in part, by a processor IC according to a software program operating therein and provides feedback to a user via a visual display, an audio alarm, and a vibrational alarm, and allows input from the user via a touch sensitive keypad. Certain input functions are restricted by password. The visual display includes an icon and fixed element display region and a bitmap display region. The fixed element display region includes time and date displays, battery and drug level displays that decrement, and a moving delivery state display. Various screens allow operational or log information to be displayed and/or user entry of commands. Program features when disabled are removed from a series of screen options that can be scrolled through.Type: GrantFiled: March 2, 2011Date of Patent: October 29, 2013Assignee: Medtronic MiniMed, Inc.Inventors: Ronald J.

Publication number: 20050262551Abstract: Access to system and user defined entities (objects, data items, or the like) is managed by a content manager. A privilege grants a user an ability to access system such controlled entities. An item is an atomic user data entity stored in the CM library server. A privileges table is used to store system and user defined privileges. A privilege is represented by a row in the table. Each privilege has a unique privilege code, with codes 0 to 999 reserved to store system-defined privileges and codes beyond 999 open for user-defined privileges thus allowing application specific privileges to be added without limit.Type: ApplicationFiled: July 15, 2005Publication date: November 24, 2005Applicant: International Business Machines CorporationInventors: An Chen, David Choy, Tawei Hu, Jy-Jine Lin, Kenneth Nelson, Yuping Wang, Alan Yang
