Abstract: A tool pack structure includes: a signature value for guaranteeing authenticity of a tool pack; a tool pack identifier for identifying the tool pack; each unit tool pack provided according to a hardware platform; and tool pack data containing initial values assigned when each unit tool pack is used. Each tool pack includes platform information indicating information about hardware in which the tool pack may be used; a tool agent that is a program activated for content execution; and a tool group including at least one tool program activated by the tool pack agent for processing content according to a predetermined rule. A tool agent leaves operation of a protection tool group used by a specific service provider entirely to a tool agent (execution code) provided together with the tool group by service providers. Accordingly, information about the used tools does not have to be disclosed to the public. Since a user terminal simply calls each tool agent, it can support interoperability with other DRM techniques.
