Abstract
A data protection program is able to effectively restrict an unauthorized access to a resource to be protected even when the resource to be protected is in a state legitimately accessed by a user. The identification information about a program capable of accessing the resource to be protected is registered in an access permission management table. If an access request to access the resource to be protected is subsequently received, then identification information about a request source program which has outputted the access request is acquired. Then, it is determined whether access to the resource to be protected is permitted or not based on whether the identification information about the request source program has been registered in the access permission management table or not. If access to the resource to be protected is permitted, data in the resource to be protected is processed in response to the access request.
