Claim 4:
5. The method of claim 4, wherein the information entropy is calculated by the following equation:, H
    =
    
     -
     
      ∑
      
       
        P
        ⁡
        (
        x
        )
       
       ⁢
       
        log
        2
       
       ⁢
       
        P
        ⁡
        (
        x
        )
       
      
     
    
   
   ;
  
  ⁢
  

  
   
    P
    ⁡
    (
    x
    )
   
   =
   
    
     n
     ⁢
     u
     ⁢
     
      m
      ⁡
      (
      x
      )
     
    
    TotalCount
   
  
 

where H represents information entropy; P(x) represents a ratio of the number of occurrence of character x to the sum of number of occurrences of all characters; num(x) represents the number of occurrence of character x; TotalCount represents the sum of number of occurrence of all characters.
