Abstract

Abstract PURPOSE:To form a publishing system for IC card with high security by ciphering the publishing information from a storing means through a transfer control means to an issuing information writing means. CONSTITUTION:When an indication for starting the publishing operation is issued to a computer 12 by operating a first card reader/writer 13, the computer 12 reads the ciphered publishing information from a memory 11, and transferred to the first card reader/writer 13 through a communication circuit. When the operator inputs the ID number to a second card reader/writer 15, the ID number is collated by the ID number stored in a second IC card, and when both numbers coincide, a decoding key is outputted from a decoding key issuing circuit 28 and supplied to a decoder circuit 21. On the other hand, the decoder circuit 12 is inputted with a cipher-issuing information transmitted from the computer 12. Hence the decoder circuit 21 decodes the cipher issuing information by using the decoding key.
