    • A decryption key management scheme for a software distribution system utilizing the decryption key, which can enable the re-install of the software that was decrypted once by a proper procedure, without requiring a re-acquisition of the decryption key from the software vender, so that a user can freely delete and re-install the software that was properly obtained once. The decryption key is searched in a memory device of a user's computer, or acquired from a distribution source of the encrypted software when the decryption key is not found in the memory means. Then, the encrypted software is decrypted by using the obtained decryption key, and a decrypted software content is installed into the memory device, while the decryption key acquired from the distribution source is stored into the memory device, such that the decryption key stored in the memory device is utilizable in decrypting the encrypted software at a time of re-installing the encrypted software.

    • A data input/output management scheme suitable for protection of electronic writing data. Whether the data entered into the program is a protected data or not is judged, and when it is, at least the identifier for identifying the program is recorded as the protected data input record. Then, a data output is permitted when the identifier for identifying the program is not recorded in the protected data input record, while whether or not to permit a data output is judged according to at least a requested output target when the identifier for identifying the program is recorded in the protected data input record. For the writing data, the application program is authenticated, and the authentication result is stored in correspondence to an identifier for identifying the application program. Then, a request for access to writing data from the application program is permitted when the stored authentication result for the application program indicates a successful authentication for the application program.

    • A memory management and protection system for realizing a high speed execution and a proper and flexible memory access control for multiple programs sharing an identical logical address space. In the system, the memory access is permitted according to a segment identifier identifying a segment in the logical address space, and a memory protection information for a region in each segment including a target right permission to indicate assigned rights to make a memory access from the region to each of the segments, and an execution permission to indicate a type of the memory access permitted by the right permission. Alternatively, a memory access can be permitted by using an access control list to be attached to each address table entry, which stores a plurality of program numbers identifying programs which are permitted to make accesses to the logical address stored in each address table entry, among which one that matches with the current program number is to be searched. Also, it is preferable to allocate a plurality of programs within a limit of available memory protection capacity to an identical logical address space, without any overlap between adjacently allocated address regions.

    • A method for managing virtual address space in which programs designed for smaller virtual address spaces in the multiple virtual memory scheme can be collectively allocated to a single enlarged virtual address space in the single virtual memory scheme efficiently, without requiring any change in the programs themselves, such that the entire virtual address space becomes available in the compatible mode. In the method, the effective addresses to be used during an execution of a program designed for a smaller address space are calculated by combining an appropriate address base for this program specifying upper bits of the effective address and lower bits of the virtual addresses for a region of the enlarged address space to which this program is allocated. The address base may be replaced by the upper bits of the starting address of the program in the enlarged address space which are retained throughout the effective address calculation. The method may use a compatible mode address region to be used in executing a program designed for a smaller address space which has virtual addresses identical to those to which this program is designed to be allocated in the smaller address space.

Detecting area is instituted by the optical system so as to put the infrared rays into a plurality of the infrared ray detectors with time difference therebetween. Signal processing unit produces a detecting signal when there is a predetermined time difference between signals produced by a plurality of the infrared ray detectors. It is possible to avoid wrong operation which is caused by popcorn noise and a differential noise having a bit of time difference caused by temperature gradient in space. Forming a curved imaginary boundary line, a plurality of detecting zones are disposed at out side and inside of the curved imaginary boundary line to detect the object invading from any direction.
