Abstract:
1. An information processing apparatus for converting digital information to restrict operations, the apparatus comprising a computer processor and memory cooperating to function as: a storage unit reading and storing the digital information; a first adding unit adding restricting attribute information to the digital information, wherein the restricting attribute information includes restricted operation information for defining contents of an operation restriction on the digital information and restricting condition information for defining conditions for applying the operation restriction on the digital information; a second adding unit adding a restricting program to the digital information, wherein the restricting program monitors and controls one or more operations on the digital information; an output unit outputting the digital information to which the restricting attribute information and the restricting program are added by the first and second adding units all together as data having an executable format, in order to apply the operation restriction on the digital information according to the restricting attribute information; and a transmission unit transmitting the data having the executable format to an other terminal, wherein said restricting program is transmitted to the other terminal with the data having the executable format, and wherein execution of said restricting program deletes the digital information of said data in response to an application activated by the other terminal releasing the digital information of said data after use of the digital information of said data by the application has ended.
