- the respective components contained in copyright management system 10 are constructed so that they are connected to each other via an internal bus.
- Personal computer 1 containing copyright management system 10 includes a central processing unit (CPU) 20 for controlling copyright management system 10 according to a purchase of a program and the respective components in PC 1, a memory 30 composed of a RAM for storing a plurality of programs, and a hard disk 40 for storing the purchased program.
- the respective components of PC 1 and I/O unit 18 of copyright management system 10 are constructed so that they are connected to each other via a PC bus. An operation of a management apparatus for copyright protection of a program-on-demand according to the present invention as constructed above will be described in more detail.
- base station 50 and copyright management system 10 play a role of mutually connecting a consumer with a software supplier. That is, base station 50 can be regarded as a software bank. Also, base station 50 are connected to copyright management system 10 with the PSTN or Internet. When purchasing a program, a purchaser should pay for the program to be purchased to base station 50. Then, a program PI which is an interface software contained in memory 30 of PC 1 is executed to connect PC 1 with I/O unit 18 in copyright management system 10.
- CPU 15 of copyright management system 10 which receives a program purchase request command from a purchaser performs a necessary operation according to an operational program contained in memory 16 composed of a ROM.
- CPU 15 can perform a numerical calculation operation and decode a program encoded in base station 50 to prevent an unauthorized copy.
- CPU 15 starts to communicate with base station 50 via one I/O unit among a plurality of I/O units 13 and 14 which are connected to different communication networks if a program purchase request command is input thereto.
- first I/O unit 13 is connected to base station 50 via the PSTN being an aerial exchangeable telephone network
- second I/O unit 14 is connected to base station 50 via the Internet.
- the Internet represents a network itself which connects spread computers with each other, or represents all sources and information which can be accessed the network.
- base station 50 and copyright management system 10 communicate with each other via a selected communication network.
- the packet exchanger 51 of base station 50 is possibly connected to a plurality of copyright management systems, and transmits a user program purchase request command applied via the I/O unit of the connected copyright management system 10 to control processor 53.
- Control processor 53 performs a necessary operation according to an operational program stored in memory 55 composed of a RAM. That is, control processor 53 recognizes a user program purchase request command and then outputs a user ID number request command of connected copyright management system 10 via the communication network.
- the ID number represents the combination of characters and figures assigned by user selection at the time of making a contract in use for user identification and user service.
- the user ID number request command is transmitted to copyright management system 10 via packet exchanger 51.
- the I/O unit of copyright management system 10 transmits the input user ID number request command to CPU 15 via an internal bus.
- CPU 15 recognizes the user ID number request command, and then transmits the user ID number stored in register file 11 via an inverse path to base station 50.
- register file 11 is composed of a ROM so that the user ID number is not altered at random.
- Control processor 53 in base station 50 discriminates whether a received user ID number is a user ID number of a copyright management system which is controlled by control processor 53 while being formed as a data base in hard disk 55.
- Control processor 53 modifies the program which is requested by the user so that the program is only run in copyright management system 10 having the user ID number and transmits the modified program to PC 1 via copyright management system 10, if the transmitted user ID number is a user ID number of a copyright management system which is controlled by control processor 53.
- the data base contained in hard disk 55 has items such as user personal particulars, user ID numbers of copyright management systems, a list of programs sold to the purchaser, and the number of use frequency and running time for 7
- CPU 15 in copyright management system 10 decodes an encoded program supplied from base station 50, and makes the encoded program executable.
- Copyright management system 10 stores the decoded program in hard disk 40 or memory 30 in PC 1.
- Base station 50 transmits the program together with the contents for restricting use of the program.
- the use restriction contents are stored in a flash memory 17 in copyright management system 10.
- the use restriction contents restrict the use frequency of the program or the running time.
- a flash memory is a kind of a non-volatile memory in which stored information does not disappear even if power is off, differently from a dynamic RAM (DRAM) or a static RAM (SRAM ).
- DRAM dynamic RAM
- SRAM static RAM
- base station 50 instructs copyright management system 10 to update the number of the use frequency upon the receipt of the request in base station 50. Then, copyright management system 10 updates the number of the use frequency stored in flash memory 17 according to an instruction of base station 50. Also, when information representing that the program is in use via I/O unit 18 is input during performing the program, the number of the use frequency stored in flash memory 17 is decreased by "1 " whenever the information is input.
- base station 50 being a program supplier publishes the fact and transmits it to a user of copyright management system 10 which constructs and manages a data base in hard disk 55.
- Base station 50 can use various methods for publishing version-updated programs. As an example, an automatic dialing function can be included in I/O units 13 and 14 of copyright management system 10.
- the operational program for selling and purchasing programs is stored in memory 30 composed of a RAM in the user's PC 1, memory 16 composed of a ROM in copyright management system 10 contained in PC 1, and memory 55 composed of a RAM in base station 50, respectively, so as to give and take mutually necessary encoded instructions.
- the mutual instructions and the selling programs communicating between base station 50 and copyright management system 10 have encoded patterns to prevent illegal use in the other copyright management systems having the other user ID numbers.
- CPU 15 in copyright management system 10 checks all components by hardware according to an operational program stored in memory 16 composed of a ROM to recognize each state of the hardware, and then sends a state report to base station 50. Such a state checking operation can be performed at the time when power is supplied, before the program is purchased, or when the purchased program is performed. Also, control processor 53 in base station 50 can check states of the copyright management systems which are controlled according to the operational program stored in memory 55 composed of a RAM.
- the present invention relates a management 9
- the management method and apparatus for copyright protection of a program according to the present invention can be applied to a program-on-demand business and a video-on-demand business using a communication network. Also, the present invention can be applied to a bidirectional cable TV (CATV) system and an interactive CATV system.
- CATV bidirectional cable TV
