摘要:
The software operation modeling device includes a function call order obtaining unit and a model generator. The function call order obtaining unit obtains or estimates an issuing order of function calls executed in each of specific events in the course of executing software. The model generator statistically grasps a co-occurrence relationship between the specific event and the issuing order of the function calls obtained or estimated by the function call order obtaining unit, and to record the grasped co-occurrence relationship as an operation model of the software.

An access controller controls access to control target resources by a program. The access controller includes a function access detection unit and a resource access control unit. The function access detection unit detects loading of a control target function from the program and generates identification information to specify an access request issued from the detected control target function. The resource access control unit obtains a request of accessing the control target resources from the program and determines permission of the access request based on the identification information.

A communications terminal apparatus, a reception apparatus, and a method can enhance the effect of reducing the amount of information to be transmitted when text data is generated and transmitted. The communications terminal apparatus 100 stores key identifier definition information in a key identifier definition-storage area 1071. The communications terminal apparatus 100 obtains a key identifier corresponding to an operated key from the key identifier definition-storage area 1071 when the key is operated, and adds and stores it as a key identifier string in the input key identifier storage area 1073. The communications terminal apparatus 100 transmits the key identifier string stored in the input key identifier storage area 1073 by the transmission function 1031 when a transmit instruction is detected.
