Patent number: 8356356Abstract: An anti-debugger comprises spatially and temporally separate detection and response portions. In an example configuration, the anti-debugger is implemented into a game system for detecting and responding to a debugger attached to a game application. The detection portion is implemented on one thread of the system and the response portion is implemented on another thread of the system. When a debugger is detected, a message indicative of the detection is provided to a thread interface. The thread interface provides the message to the response portion. After a period of time has elapsed, the response portion disables the functionality of the game application, such as by halting the game execution and/or obfuscating game performance.Type: GrantFiled: January 30, 2007Date of Patent: January 15, 2013Assignee: Microsoft CorporationInventors: Vito Sabella, Aaron Khoo, Chao Gu

Patent number: 8201265Abstract: A method is disclosed for generating a read error during standard DVD disc manufacturing. The method generates a read error in an error correction code (ECC) block including a specific error generation data pattern, when main data of 2,048 bytes is generated using the specific error generation data pattern according to a DVD standard. The error-pattern original data is inserted into the main data that is scrambling based on a DVD standard. The scrambled data is recorded in data sectors. The scrambled data including an error pattern which causes a read error is consecutively recorded in the data sectors included in the ECC blocks, in a process in which the data sectors are grouped based on 16 units to form the ECC blocks.Type: GrantFiled: February 28, 2007Date of Patent: June 12, 2012Assignee: SETTEC, Inc.Inventor: Heung-Chan Seung

Patent number: 8200931Abstract: A software installation system comprises an interface component that receives a request to access data resident upon a flash memory card. An installation component compares a unique identifier associated with the data with a unique identifier embedded within the flash memory card, and the installation component determines whether to allow access to the data based at least in part upon the comparison. The installation component prohibits access to the data if the unique identifier associated with the data does not match the unique identifier embedded within the flash memory card.Type: GrantFiled: June 1, 2011Date of Patent: June 12, 2012Assignee: Rockwell Automation Technologies, Inc.Inventors: Joseph Francis Mann, William N. Schroeder

Patent number: 8190914Abstract: Methods and systems for designating and handling confidential memory allocations of virtual memory are provided in which the operating system provides a memory allocation flag that applications may use to indicate any arbitrary area of physical memory marked with this flag may contain confidential data and should be handled accordingly. The operating system also ensures that memory allocated with this flag can be placed in physical memory. When freeing up memory, the operating system protects any data in the memory allocated with this flag. For example, the operating system may prevent the confidential memory from being swapped out to storage or from being accessible to other applications, such as a debuggers. Alternatively, the operating system may encrypt any data in the confidential memory before it is swapped out to storage.Type: GrantFiled: February 28, 2006Date of Patent: May 29, 2012Assignee: Red Hat, Inc.Inventors: Henri Han van Riel, Alan Cox

Publication number: 20120131686Abstract: A method for selectively controlling access to electronic media disposed on a media storage device according to one embodiment is described. The method comprises creating a first list comprising a plurality of process identification values. Each of the plurality of process identification values of the first list is associated with a software application that is accessing the media disposed upon the media storage device. The method further includes creating a second list comprising a second plurality of process identification values. Each of the second plurality of process identification values is associated with a software application that is storing data. The method further includes determining that a particular software application is creating an unauthorized copy of the media disposed upon the media storage device. The method further includes preventing the particular software application from storing a usable copy of said electronic media.Type: ApplicationFiled: November 21, 2011Publication date: May 24, 2012Inventors: Hank Risan, Edward Vincent Fitzgerald
