Method and apparatus for communication between heterogeneous platforms

A communication method of a first platform server that interacts with a second platform server providing a different platform through an interaction server, the communication method being performed by the first platform server and comprising:

• transmitting, to the interaction server, a token request and first user identification information, the first user identification information being registered with the first platform server;
• receiving, from the interaction server, a token that is created based on integrated user identification information corresponding to the first user identification information, wherein the integrated user identification information is created by the interaction server and refers to user identification for the interaction between the first and second platform servers;
• transmitting, to the second platform server, the token and a request for a device registered with the second platform server;
• and
• receiving a processing result of the request for the device from the second platform server,
• wherein the second platform server is configured to transmit the processing result of the request for the device to the first platform server, when the second platform server receives second user identification information, which corresponds to the integrated user identification information and is registered with the second platform server, from the interaction server which determines that the token transferred from the first platform server to the second platform server is valid, to thereby allow a device registered with the first platform server to control the device registered with the second platform server,
• wherein the token is created by encoding the integrated user identification information, and
• wherein the integrated user identification information is changed at predetermined intervals.

A communication method of a second platform server that interacts with a first platform server providing a different platform through an interaction server, the communication method being performed by the second platform server and comprising:

• receiving, from the first platform server, a token and a request for a device registered with the second platform server, wherein the token is created based on integrated identification information corresponding to first user identification information registered with the first platform server in response to a token request from the first platform server, and wherein the integrated user identification information is created by the interaction server and refers to user identification for the interaction between the first and second platform servers;
• after the token is transferred from the first platform server to the second platform server, transmitting, to the interaction server, a request for verifying validity of the token;
• and
• receiving second user identification information, which corresponds to the integrated user identification information and is registered with the second platform server, from the interaction server which determines that the token is valid, to thereby allow a device registered with one of the first and second platform servers to control a device registered with another of the first and second platform servers,
• wherein the token is created by encoding the integrated user identification information, and
• wherein the integrated user identification information is changed at predetermined intervals.
