Gateway device and data collection method

A data correction method executed by a gateway device that accesses to an information processing device configured to search for data based on search key information corresponding to data transmitted from a plurality of apparatuses, the method comprising:

• transmitting first search key information to the information processing device, the first search key information corresponding to data received from at least one of the plurality of apparatuses;
• determining whether second search key information has been sent to the information processing device, the second search key information corresponding to data received at an other gateway device from at least one of the plurality of apparatuses and the second search key information being integrated to the gateway device from the other gateway device in a case that the gateway device is determined as a representative gateway device by the information processing device;
• and
• transmitting the second search key information corresponding to a plurality of pieces of data received at the other gateway device to the information processing device, when the second search key information has not been sent to the information processing device;
• wherein the representative gateway device continues to receive the second search key information from the other gateway device based on a first ratio and a second ratio,
• wherein the first ratio indicating current integration ratio information at the representative gateway device, is a number of pieces of the first and the second search key information transmitted to the information processing device from the representative gateway device, to a sum of a number of pieces of data received at the representative gateway device from the plurality of apparatuses and a number of pieces of the second search key information received from the other gateway device, and
• wherein the second ratio indicating single integration ratio information is a number of pieces of third search key information transmitted to the information processing device from the other gateway device, to a number of pieces of data received from the plurality of apparatuses at the other gateway device, in a case that the other gateway device does not transmit the third search key information to the representative gateway device.

A data correction system comprising:

• a plurality of gateway devices configured to store data transmitted from a plurality of apparatuses;
• and
• an information processing device configured to search for the data based on search key information corresponding to the data, wherein
• the information processing device includes:
• a first memory;
• and
• a first processor coupled to the first memory and configured to:
• receive search key information from at least one of the plurality of gateway devices, the search key information including identification indicating the data transmitted from a particular apparatus of the plurality of apparatuses, and apparatus information indicating the particular apparatus;
• identify a particular apparatus information as integrated apparatus information, the particular apparatus information being included in two or more search key information from two or more gateway devices which transmit the search key information corresponding to the particular apparatus of the plurality of the apparatuses;
• determine one of the two or more gateway devices as a representative gateway device, based on a number of transmission of the search key information corresponding to the particular apparatus, the representation gateway device transmitting the search key information corresponding to data transmitted from the particular apparatus, the data being received at other gateway devices of the two or more gateway devices;
• and wherein
• each of the plurality of gateway devices includes:
• a second memory;
• and
• a second processor coupled to the second memory and configured to:
• transmit first search key information to the information processing device, the first search key information corresponding to data received from at least one of the plurality of apparatuses;
• determine whether second search key information has been sent to the information processing device, the second search key information corresponding to data received at an other gateway device from at least one of the plurality of apparatuses and the second search key information being integrated to the gateway device from the other gateway device, in a case that the gateway device is determined as the representative gateway device by the information processing device;
• and
• transmit the second search key information corresponding to a plurality of pieces of data received at the other gateway device, to the information processing device, when the second search key information has not been sent to the information processing device, in the case that the gateway device is determined as the representative gateway device by the information processing device;
• wherein the representative gateway device continues to receive the second search key information from the other gateway device based on a first ratio and a second ratio,
• wherein the first ratio indicating current integration ratio information at the representative gateway device, is a number of pieces of the first and the second search key information transmitted to the information processing device from the representative gateway device, to a sum of a number of pieces of data received at the representative gateway device from the plurality of apparatuses and a number of pieces of the second search key information received from the other gateway device, and
• wherein the second ratio indicating single integration ratio information is a number of pieces of third search key information transmitted to the information processing device from the other gateway device, to a number of pieces of data received from the plurality of apparatuses at the other gateway device, in a case that the other gateway device does not transmit the third search key information to the representative gateway device.
