Abstract
Computer-readable media, computerized methods, and computer systems for protecting secure data by writing content of the secure data to a protected memory segment are provided. Initially, streaming media is received from a media-reading device and portions of the streaming media are identified as secure data. A data-management process to protect content within the secure data is executed. During execution, the protected memory segment is instantiated, a region of memory is dynamically allocated to hold the protected memory segment, and content of the secure data is written thereto. The protected memory segment is generally a data store that conditionally limits access thereto utilizing hardware-based rules, thereby guarding the content against exposure to unauthorized systems and to attackers. The region of memory may be allocated on CPU hardware, GPU hardware, or a combination thereof. The content may then be encrypted and released for conveyance to one or more presentation devices.
