PURPOSE:To allow user's secrecy protecting information to reside in a memory and to reduce the number of I/O accesses by extracting only information required for an opposite side process from the secrecy protecting information and transferring the extracted information. CONSTITUTION:It is supposed that necessity for transferring a processing request to another memory space is generated by work requested by the user. A transfer processing block 25 requests the retrieval of a user's property information control table and the offer of user's property information to a user's property information control block 22. The sent request is received by a space connection receiving processing block 28 in the opposite memory space and the user's property is read out by the block 25. The read user's property information is transferred to the block 22 and a user's property control table is formed based upon the user's property information. Thus, the user's property information can be residentially controlled without executing the I/O access of an external storage device 29 in the memory space on the receiving side. |
