ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a method for managing information generated by a computer system and a software program serving as information for generating information by a computer system and a recording medium.
In accordance with the advancement of recent computer arts, a lot of various digitized pieces of information has circulated through electronic networks. Conventionally, a software program (hereafter referred to as authoring program) for processing file data (hereafter referred to as contents) serving as information unit to be processed by a computer system is installed from a recording medium such as a CD-ROM or a flexible disk or down-loaded on-line through a network, and captured by the computer system, and then each of the contents is processed by the program.
In the above state, management of authoring programs and contents such as assuring of copyright, preventing of alteration, or maintaining of security requires a technique basically different from conventional prevention of copying of paper-based information printed on paper or storage of data in a lockable place. Contents have been enciphered so far for security. However, enciphering of contents is not generalized yet and therefore, it can be hardly said that this is popular.
By making it possible to securely perform the above-described enciphering of contents, information management at each user level may be possible to a certain extent. However, processing of enciphering and operation for decoding are troublesome for each user. Moreover, to make the above mentioned widely circulate through the society, universal enciphering algorithm is necessary. However, to meet the necessity, the enciphering algorithm must be opened to the public. Therefore, this causes various problems.
The present invention is made to solve the above problems and its object is to provide an information management method and a recording medium making it possible to identify each authoring program and contents by providing unique ID for each authoring program and contents.
BRIEF SUMMARY OF THE INVENTION
The present invention makes it possible to identify each authoring program and contents circulating through the society by providing an identifier (unique ID) for each authoring program, transferring the unique ID of the authoring program processing each contents to each contents when handling contents by using the authoring program, and moreover providing each contents with a unique ID. It is an object of the present invention to easily manage information by the above technique and easily apply the technique to various fields including copyright protection and security.
In the case of the present invention, each authoring program and contents have a unique ID. Therefore, if the authoring program or contents is or are copied, the unique ID is also copied. Therefore, whether the authoring program or contents is or are illegally owned can be immediately decided by referring to the unique ID of the authoring program or contents. That is, it is possible to specify the environment in which the authoring program is installed or the contents is created in accordance with the unique ID of the authoring program or contents. Therefore, by comparing the environment with the environment at the present, it is possible to decide whether the authoring program or contents is or are illegally obtained. Moreover, when unique IDs are changed after obtaining an authoring program or contents through copying, it is impossible to use the authoring program or make an access to the contents. Therefore, copying of the authoring program or contents does not make sense.
In the case of the first aspect of an information management method of the present invention, when a recording medium in which a software program for creating and/or processing a file data is recorded is manufactured, a unique identifier generated so as to be read together with the software program is recorded in the recording medium.
Moreover, in the case of the first aspect of an information management method of the present invention, when a recording medium in which a software program for creating and/or processing a file data is recorded is manufactured, a unique identifier generated so as to be read together with the software program is recorded in the recording medium and thereby, making it possible to identify each software program when the unique identifier is installed into a computer system.
Furthermore, in the case of the first aspect of a recording medium of the present invention, a unique identifier generated so as to be read together with a software program for creating and/or processing a file data is recorded in a recording medium in which the software program is recorded.
Furthermore, in the case of the first aspect of a recording medium of the present invention, a unique identifier generated so as to be read together with a software program for creating and/or processing file data is recorded in the recording medium in which the software program is recorded and therefore, it is possible to identify each software program when the identifier is installed into a computer system.
Furthermore, in the case of the second aspect of an information management method of the present invention, when an authorization for installation into a computer system is given from an on-line-connected management center, installation into the computer system can be made. Therefore, when a software program for creating and/or processing a file data is installed into the computer system, a unique identifier generated by the management center so as to be read together with the software program is installed into the computer system.
In the case of the second aspect of an information management method of the present invention, when an authorization for installation into a computer system is given from an on-line-connected management center, installation into the computer system can be made. Therefore, when a software program for creating and/or processing a file data is installed into a computer system, a unique identifier generated so as to be read together with the software program is generated by the management center and installed into the computer system. Therefore, when the software program is installed into the computer system, it is possible to identify each software program.
Moreover, in the case of the second aspect of a recording medium of the present invention, a unique identifier generated by a management center so as to be read together with a software program for creating and/or processing a file data is recorded in a recording medium in which the software program is recorded because an authorization for installation of the software program into a computer system is given from a on-line-connected management center and thereby, the software program is installed into the computer system.
Furthermore, in the case of the second aspect of a recording medium of the present invention, because a unique identifier generated by a management center so as to be read together with a software program for creating and/or processing a file data is recorded in a recording medium in which the software program is recorded because an authorization for installation of the software program into a computer system is given from a on-line-connected management center and thereby, the software program is installed into the computer system. Therefore, when the software program is installed into the computer system, it is possible to identify each software program.
In the case of the third aspect of an information management method of the present invention, when a software program for creating and/or processing a file data is installed into a computer system, a unique identifier to be read together with the software program is generated in accordance with the information intrinsic to the computer system and installed into the computer system.
Moreover, in the case of the third aspect of an information management method of the present invention, when a software program for creating and/or process
