<p>A cellular phone (40) encapsulates data of high level of importance and contents the copyright of which must be protected, stored in the cellular phone (40) and treats the capsulated data as a completely capsulated object that has only a method that will not pass the capsulated data to an operating program. A JavaAP downloaded in the cellular phone (40) issues an instruction to the completely capsulated object to instruct an operation on the capsulated data in the object using a method provided in the object. This does not lose the convenience of a program provided via a network and ensures the security of such a program.</p> |
