Abstract

A code includes a first part printed by using a first pigment, and a second part printed by using a second pigment which is easier to discolor than the first pigment, wherein the code is decodable by using information about discoloration of the second pigment.

1 . A code comprising:
 a first part printed by using a first pigment; and   a second part printed by using a second pigment which is easier to discolor than the first pigment, wherein   the code is decodable by using information about discoloration of the second pigment.   
     
     
         2 . The code according to  claim 1 , wherein identification information for identifying the information about discoloration of the second pigment is obtained by decoding the first part. 
     
     
         3 . The code according to  claim 1 , wherein the code is decodable by using data in a database which stores a relationship between information on time and information on color. 
     
     
         4 . The code according to  claim 1 , wherein the first pigment and the second pigment are different from each other in a fading speed at a predetermined temperature. 
     
     
         5 . The code according to  claim 1 , wherein the first pigment and the second pigment are different from each other in scratch characteristics. 
     
     
         6 . The code according to  claim 1 , wherein the first pigment and the second pigment are different from each other in ozone resistance. 
     
     
         7 . An information processing method for decoding the code according to  claim 1 . 
     
     
         8 . An information processing method for encoding the code according to  claim 1 . 
     
     
         9 . An information processing apparatus for executing the information processing method according to  claim 7 . 
     
     
         10 . (canceled) 
     
     
         11 . A non-transitory computer readable storage medium which stores a program configured for executing the information processing method according to  claim 7  by a computer. 
     
     
         12 . An ink used for printing the code according to  claim 1 . 
     
     
         13 . A pigment contained in the ink according to  claim 12 . 
     
     
         14 . A storage device which stores the information about discoloration of the second pigment for decoding the code according to  claim 1 . 
     
     
         15 . An information processing apparatus which is connected to the storage device according to  claim 14 , and configured to store the information about discoloration of the second pigment into the storage device. 
     
     
         16 . A code comprising:
 a first part printed by using a first pigment; and   a second part printed by using a second pigment which is easier to discolor than the first pigment, wherein   a first result is obtained if only the first part is decoded, and a second result is obtained if both the first part and the second part are decoded.
