An application is activated with access permission to resources which are granted to unsigned applications. In parallel with the execution of the application, tamper check is performed on the application using a tamper check thread. When access to a resource which is not granted to unsigned applications is requested during the execution of the application before the completion of the tamper check, the application is put in a wait state until the completion of the tamper check. After the application is judged as having been untampered with as a result of the tamper check, the application is further granted access permission to resources that are specified by a permission information file included in the application. If this further-granted access permission includes the access right to the resource, the execution of the application is continued.

Application execution device, application execution method, integrated circuit, and computer-readable program

The embedded program comprises a part of the function of the Java program. The embedded program executes the part of the function during the start-up processing period of Java program. Thus, the start-up time appears to be shortened. Further, the present invention provides the information regarding the action state of the embedded program to the Java program, thereby enabling a consistent execution of the Java program on completion of the Java program start-up process.

Program executing apparatus

A disk reproducing apparatus and a disk reproducing method which permit continuous reproduction of data of the RTR type without interruption and without affecting real time reproduction. A defective block list with defective blocks and alternative blocks registered linked to each other by the types of defective blocks has been acquired beforehand from a recording medium and when there arises need to read a defective block, its alternative block is read out and forwarded to a reproduction requester. Here, reading control means identifies the type of defective blocks registered on the defective block list and controls the reading according to the identification results.
