摘要： One embodiment of the present invention provides a system for deleting objects from a memory in a computing device, wherein the memory includes both a volatile memory and a non-volatile memory that is writeable. During operation, the system receives a request to perform an object deletion operation, which locates and deletes unused objects from the memory. In response to this request, the system performs the object deletion operation by first performing a marking operation that marks objects that are reachable in the non-volatile memory. This marking operation does not directly mark the objects in the non-volatile memory, but instead marks data values in the volatile memory that are associated with the objects. In this way, unnecessary write operations to non-volatile memory are avoided. Next, the system performs a sweep operation that deletes unmarked objects from the non-volatile memory.

摘要： A system and method of flexibly loading an application and its associated data from an application provider onto an IC card. The application and its associated data is divided into segments which can each fit into the input buffer of an Integrated circuit card. Each segment is transmitted separately and the Integrated circuit card then stores the segment in an available space in the IC card's memory. The segments can be placed in non-contiguous memory in order to reduce memory fragmentation.

摘要： When an operation relating to print processing is to be instructed, a user information producing section produces an identification of a user and transmits the operation in a user name to which the identification is attached. A correctness inquiry judging section judges whether it is necessary to verify correctness of the identification, in accordance with a security policy stored in a support authentication level storing section. If necessary, a user verifying section is requested to verify the correctness. The user verifying section performs user verification corresponding to an authentication level. In a high level, reverification of the identification is performed by an authenticating section. In a middle level, user authentication based on an authentication scheme of the client environment is used. In a low level, the system believes the user name designated by the user. An operation controlling section judges whether the operation is allowed to the verified user.

摘要： The card has a plastic support bearing, on at least one part of its surface, a layer of recording material and a microcircuit inserted in the plastic support. The card is made tamper-proof by the setting up of an identifier code that is characteristic of the relationship between the microcircuit and the support bearing the recording layer. This code is, firstly, recorded in the memory of the microcircuit and, secondly, detectable by analysis of the support. Any detachment of the support and of the microcircuit in which the related code has been memorized prevents the checking of the two codes by coincidence. The invention can be applied notably to high storage density cards.
