1. A method for processing noise of glucose level measurement data, by a continuous blood glucose measurement system including a sensor transmitter and a communication terminal communicating with each other, the method comprising:
measuring a glucose level, by the sensor transmitter configured to periodically measure the glucose level of a user;
generating, by the sensor transmitter, a first noise processed data by processing noise of data of the glucose level;
transmitting the first noise processed data of the glucose level from the sensor transmitter to the communication terminal;
generating, by the communication terminal, a second noise processed data by processing noise of the first noise processed data;
verifying, by the communication terminal, the second noise processed data when a verification value is within a verification range, the verification value calculated using the first noise processed data;
performing a linear regression filtering on the second noise processed data if the second noise processed data is not verified, by the communication terminal; and
outputting, on the communication terminal, the second noise processed data when the second noise processed data is verified, or data processed by the linear regression filtering.
