Algorithm 1 The pseudo-code of data acquisition, validation, and visualization

1: Read data from the smart meter

2: Input the data to the Decision tree model

3: Classify the data by the Decision tree

4:   if the output of the Decision tree == 1

5:       Publish that the data is ‘Real’

6:   else

7:       Publish that the data is ‘Fake’

8:   end if

9: Record the receiving time of data

10: Calculate the change of time

11:   if the change of time ≤ sample rate of the smart meter

12:       Publish ‘No loss data’

13:   else

14:       Publish ‘There is loss data’

15:   end if

16: Publish the reading of the smart meter
