PROBLEM TO BE SOLVED: To provide a recording material for identification that has proofness for a forgery or alteration by a change of a picture for identification or the like or for a forge of storage information and so on. SOLUTION: In an individual identification card 1 that has a face picture part 10 on which a face picture of a card holder of a picture for identification is print-recorded and a magnetic recording part 14 as a information storage part, part of the face picture part 10 is provided with a buried picture part 16 in which bar code information as a cryptographic key for specifying an individual that becomes a variable for a predetermined enciphering processing is superimposition recorded on the face picture as a pattern that cannot be identified by visualization but be identified through a specific reproduction filter. Also, the magnetic recording part 14 records personal information that is enciphered by the enciphering processing by using the cryptographic key.
