Abstract: A device implementing a system for object placement includes at least one processor configured to identify an object stored on two of a plurality of storage devices, and to determine a pairing value for each pair of the plurality of storage devices, the pairing value corresponding to a number of stored objects common to the pair. The at least one processor is further configured to select, based on the determined pairing values, two storage devices having a lowest pairing value relative to the determined pairing values, and to move the object to each of the two selected storage devices.

Abstract: A system and method for memory management in a smart card are disclosed. The memory manager, preferably part of a true operating system, is the single device by which memory in the smart card is allocated and deallocated. Memory allocation for new data objects and memory deallocation as the result of data object deletion are made by reference to a memory management record, preferably a bitmap, which is stored in RAM and formed upon smart card initialization.

Abstract: A set of related routines allows an application to be securely installed on, or de-installed from a smart card or other portable token. The capabilities of a true operating system on the smart card are used to facilitate installation/de-installation.
