Claim 13:
14. The non-volatile computer-readable storage medium according to claim 13, wherein the computer program is executed by one or more processors to implement:
based on the cosine distance matrix, calculating the difficulty vector corresponding to the multiple identification objects according to the following conditional formula:, C
    i
   
   =
   
    
     max
     
      n
      ≠
      i
     
    
    
     D
     ⁡
     (
     
      i
      ,
      n
     
     )
    
   
  
  ;
  and
 

 
  C
  =
  
   {
   
    
     C
     1
    
    ,
    
     C
     2
    
    ,
    
     C
     3
    
    ,
    …
      
    ,
    
     C
     N
    
   
   }
  
 

wherein, “i” indicates that a row number in the cosine distance matrix D is an i-th row, “n” indicates that a column number in the cosine distance matrix D is an n-th row or an n-th column; “C” represents the difficulty vector corresponding to the multiple identification objects; C_i represents a difficulty of distinguishing the identification objects, N represents the number of identification objects.
