摘要： An image drawing system, an image drawing server, an image drawing method, and a computer program product that provides a three-dimensional world to a client-terminal. The method includes: providing a viewpoint in the vicinity of an avatar and creating a three-dimensional object; performing a perspective projection of a static object to create a two-dimensional panoramic image; overlaying the two-dimensional panoramic image, information on a dynamic object, and an image of the avatar; and storing the two-dimensional panoramic image. The computer program product tangibly embodies instructions which when implemented causes a computer to execute the steps of the method. The system includes: a three-dimensional object creation unit; a panoramic image creation unit; a drawing unit for overlaying; and a panoramic image storage unit. The server includes: a reception unit; a three-dimensional object creation unit; a panoramic image creation unit; and a transmission unit.

摘要： According to the present invention, a secret key cryptosystem and tamper-proof hardware are used to realize a pseudo-public key cryptosystem at a low cost. A trap-door one-way function is substantially realized with the use of tamper-proof hardware. Each user performs communication using equipment provided with hardware having the same capabilities described below. Such hardware retains association between an ID and a key. In response to a request from a user, the hardware issues and stores an ID, and it can perform decryption and generation of a MAC (message authentication code) with a key associated with the ID. A user publishes his ID. When performing encryption, a message sender encrypts a message using the published ID. A third person can perform decryption with the ID only by analyzing the mechanism in the hardware. However, the hardware has a capability of destroying itself when such an act is attempted.

摘要： Enhances program efficiency by performing optimization with reduced influence of an explicit instruction for adjusting an image of local variables of a code column executed by means of an interpreter and a compiled code column. An example embodiment, includes: setting code that is ignorable in predetermined transformation for a second code column among codes in a first code column, which affects transformation of the second code column; and performing predetermined transformation for the second code column by ignoring the code that is set to be ignorable, when an execution object of a program transitions from a first code column executed by means of an interpreter to a second compiled code column. It can further include generating a compensating code required for transforming a second code column including propagation of a copy instruction, and inserting the code into a first code column prior to transformation of the second code column.

摘要： A computer for a service provider receives from each member of two groups who is a user of a service via a mediating computer, a priority list in which member IDs of the other group is permuted in the priority order of a user and processing information that are encrypted so as not to be decrypted by the mediating computer. The ID of the priority list is encrypted with an encrypting key that is common to all members. The computer for a service provider performs matching, with ID in the priority list being left encrypted when the list is decrypted. The computer for a service provider decrypts the processing information, makes it in a state in which the matching result can be decrypted based on the processing information by only a person concerned, and sends it to each member via the mediating computer.

摘要： A compiler includes a register allocator for allocating registers for instructions in a program to be compiled, and a code generator for generating object code based on the register allocation results performed by the register allocator. The register allocator allocates logical registers for instructions in the program to be compiled. The register allocation further allocates, to physical registers, the logical registers that are allocated to the instructions of the program, so that the physical registers that are live at a procedure call in the program to be compiled are allocated from the bottom of the register stack.

摘要： In order to improve the efficiency of execution of a program by prefetching data necessary to execute the program, a system is provided that causes a computer to execute a recursive query prior to a program being subjected to prefetching. This system detects from iterative processing in the program a query to generate a resultant table by selecting a record that satisfies a selection condition from a target table. The system generates an initial query to generate an initial table that includes values of variables that are set prior to starting the iterative processing in the program. Furthermore, the system generates a recursive query to generate the next intermediate table that is referred to in the next and later cycles of the iterative processing, in the recursive query corresponding to each cycle of the iterative processing that is sequentially performed, from an intermediate table that includes resultant tables generated by a target query in the preceding cycles of the iterative processing and the target table. Furthermore, the system generates a final query to generate a final table from the intermediate table sequentially generated by the recursive query.
