Asset management system, asset management method, information processor, management device, and program

An asset management method, comprising:

• in an information processor,
• a searching step of searching for a network address converter for converting between a local IP address and a global IP address in a network;
• a positional information obtaining step of creating positional information including at least one of said global IP address of said searched network address converter and a domain name corresponding to said global IP address and identification information of the information processor;
• a transmitting step of transmitting said positional information to a management device which manages a geographical position of said information processor;
• in said management device,
• a registration step of recording said positional information received from said information processor in a position recording unit, wherein
• when failing in said searching for the network address converter, said positional information obtaining step creates said positional information including at least one of an IP address assigned to the information processor and the domain name corresponding to the IP address and the identification information of the information processor.

An information processor having a communication function, comprising:

• a search unit which searches for a network address converter for converting between a local IP address and a global IP address in a network;
• a positional information obtaining unit which creates positional information including at least one of said global IP address of said searched network address converter and a domain name corresponding to said global IP address and identification information of the information processor;
• and
• a position information transmitting unit which transmits said positional information to a management device which manages a geographical position of the information processor, wherein
• when failing in said searching for the network address converter, said positional information obtaining unit creates said positional information including at least one of an IP address assigned to the information processor and the domain name corresponding to the IP address and the identification information of the information processor.

A management device for managing a geographical position of one or more information processors having a communication function, comprising:

• means for receiving unit which receives positional information including at least one of a global IP address of a network address converter, which converts between a local IP address and the global IP address in a network, and a domain name corresponding to the global IP address and identification information of said information processor from said information processor,
• a position recording unit which records said positional information of said one or more information processors,
• a positional information registration unit which records said positional information received from said information processor in said position recording unit, an unknown asset recording unit which records identification information of a lost information processor, and
• an unknown asset detecting unit which detects that said positional information including the same identification information as the identification information recorded in said unknown asset recording unit is recorded in said position recording unit.

A program performed by a computer forming an information processor having a communication function, comprising:

• a searching function of searching for a network address converter which converts between a local IP address and a global IP address in a network;
• a positional information obtaining function of creating positional information including at least one of said global IP address of said searched network address converter and a domain name corresponding to said global IP address and identification information of the information processor;
• and
• a position transmitting function of transmitting said positional information to a management device which manages a geographical position of said information processor, wherein
• when failing in said searching for the network address converter, said positional information obtaining function creates said positional information including at least one of an IP address assigned to the information processor and the domain name corresponding to the IP address and the identification information of the information processor.

A program performed by a computer forming a management device for managing a geographical position of one or more information processors having a communication function, comprising:

• a function of receiving positional information including at least one of a global IP address of a network address converter, which converts between a local IP address and the global IP address in a network, and a domain name corresponding to the global IP address and identification information of said information processor from said information processor,
• a position recording function of recording said positional information of said one or more information processors,
• a positional information registration function of recording said positional information received from said information processor in a position recording unit,
• an unknown asset recording function of recording identification information of a lost information processor, and
• an unknown asset detecting function of detecting that the positional information including the same identification information as the identification information recorded in an unknown asset recording unit is recorded in said position recording unit.
