`ELECTRONIC TICKET VENDING SYSTEM
`AND METHOD THEREOF
`
`BACKGROUND OF THE INVENTION
`
`l.FlELD OF THE INVENTION
`
`The present invention relates to an electronic ticket vend-
`ing system or an electronic ticket vending/refunding system
`and a method thereof using electronic information
`(hereinafter called electronic money or electronic cash)
`having the value of money for purchasing commodities.
`receiving services. or cashing a check or electronic infor-
`mation (electronic ticket) on train tickets or concert admis-
`sion tickets which are generally called tickets.
`2.DESCRIP'TION OF THE PRIOR ART
`
`Conventionally. to purchase a train ticket or a concert
`ticket. it is generally necessary to go to a counter for vending
`tickets. The reason is that a ticket is a printed paper and it is
`necessary to pay the cost of the ticket. Some ticket may be
`purchased by telephone. though it is necessary to mail the
`ticket. In this case. a credit card. bank transfer. mail transfer.
`or cash registration is used so as to pay the cost of the ticket.
`However. in the case of bank transfer. mail transfer. or cash
`registration. it is necessary to go to a bank or a post oflice.
`Recently. as a new settling means. for example. there is a
`method using electronic data (hereinafter referred to as
`electronic money) having the value of money which is
`disclosed in Published Unexamined Patent Application
`(Based on International Application) 5-504643. In this con-
`ventional example. a means for storing electronic money
`(hereinafter called an electronic purse). a means for trans-
`ferring electronic money between a host computer of a bank
`and an electronic purse. a means for transferring electronic
`money between two electronic purses. and a means for
`preventing forgery or illegal reproduction of electronic
`money are described. In this example. as a means for
`preventing forgery and illegal reproduction of electronic
`money. an asymmetric encryption algorithm represented by
`the RSA (Rivest Sharnier Adleman) algorithm and a sym-
`metric encryption algorithm represented by the DES (Data
`Encryption Standard) are used.
`By using an electronic money system having these
`encryption arts. electronic money can be transferred safely
`between two electronic purses connected by a telephone
`line. The encryption arts used in this conventional example
`can be applied also to transfer of electronic ticket informa-
`tion by a public line such as telephone. Namely. when an
`electronic ticket having electronic ticket information printed
`on a paper. the aforementioned electronic money as a means
`for paying the ticket cost. and a physical storage medium
`such as an IC card storing them are used, by using a
`communication means such as telephone. a ticket can be
`purchased without going to a ticket vending window. a bank.
`or a post office. In the same way. refunding of the ticket cost
`due to cancel of the ticket can be executed by using a
`communication means such as telephone.
`An electronic ticket storing just electronic ticket inforrna-
`tion may be easily forged or reproduced illegally. By using
`encryption by an asymmetric algorithm equivalent to the
`means for preventing forgery and illegal reproduction of
`electronic money which is used in the method disclosed in
`Published Unexamined Patent Application 5-504643 men-
`tioned above. illegality can be prevented to a certain extent.
`In the encryption method in the aforementioned conven-
`tional example. when electronic money is sent between
`electronic
`
`purses storing electronic money. by using the only com-
`mon global secret key in one electronic money system
`as a means for judging whether the opposite of com-
`munication belongs to the same electronic money sys-
`tem as that of oneself or not. a local secret key used by
`each electronic purse when money is sent between
`electronic purses is signed electronically. All electronic
`purses belonging to the aforementioned electronic
`purse system have a global public key corresponding to
`the aforementioned global secret key. so that by using
`the global public key. the encryption method can judge
`whether the opposite of communication belongs to the
`same electronic money system as that of oneself or not.
`There is a so-called prepaid card for purchasing by
`prepaying the cost as electronic money. A prepaid card
`does not have a function for using for anything like
`money. and objects to be purchased (commodities or
`services) are decided. and information to be stored is
`just data of frequency equivalent to the selling price.
`Particularly. since a prepaid card cannot cancel or
`refund a purchased object. it is dilferent from electronic
`money which functions like money.
`However. if it is attempted to apply an electronic money
`system having the aforementioned encryption art of the prior
`art to an electronic ticket vending and purchasing system
`using a public line such as telephone. there is only one kind
`of common global secret key and it is not signed electroni-
`cally on the electronic money itself. so that the problems
`described hereunder are imposed.
`When a plurality of ticket publication sources (for
`example. a railroad corporation. airplane company. event
`promoter. etc.) share the same electronic ticket system. in
`other words. when electronic tickets published by different
`- ticket publishers are stored and used in one kind of elec-
`tronic ticket storage device at the same time or one after
`another. a ticket publisher may forge or reproduce illegally
`a ticket published by another ticket publisher by using the
`I/O interface. command interface. or encryption mechanism
`of the electronic ticket storage device. Therefore. when the
`same electronic ticket storage device is shared. a means for
`preventing forgery and illegal reproduction of a ticket by
`another ticket publisher is necessary. There is an IC card
`(also called a smart card) as a typical example of the
`electronic ticket storage device.
`Furthermore. when ticket information stored in the elec-
`tronic ticket storage device is encrypted. to confirm the
`ticket information stored in the electronic ticket storage
`device by a ticket purchaser. a terminal device having a
`decryption means is necessary. However. in consideration of
`convenience. it is desirable that a portable terminal device
`on the market can be used.
`
`When cash or a ticket is given or received by telephone.
`a ticket purchaser and a ticket vender are located away from
`each other. so that a trouble may be caused that cash or a
`ticket is stolen off or cash or a ticket is not given or received
`actually. For example. when a ticket purchaser makes a
`claim for that he receives no ticket after he purchases a ticket
`and pays electronic money as a cost of the ticket. the ticket
`purchaser may tell the truth or make a false statement. Even
`when a ticket purchaser makes a claim for that no electronic
`money is sent to him alter he transfers his ticket to the ticket
`vender so as to refund the ticket. the same is caused.
`Furthermore. it is assumed that to refund the ticket cost.
`a ticket purchaser sends an electronic ticket to a ticket
`vender first and the ticket vender checks the validity of the
`ticket and then sends the ticket cost to the ticket purchaser
`by electronic money. When an electronic ticket is to be sent.

`
`if a copy of the electronic ticket is sent to the ticket vender
`without deleting the electronic ticket and the electronic
`ticket storage device (IC card) is pulled out forcibly from the
`terminal device at the same time that the ticket cost is sent
`from the ticket vendcr. a problem arises that the valid ticket
`and the refunding cost of the ticket exist on the ticket
`purchaser side at the same time. On the other hand. when an
`electronic ticket is deleted from the electronic ticket storage
`device so as to send the electronic ticket. if a communication
`failure occurs before the ticket refund reaches the ticket
`purchaser after the electronic ticket is sent. a status that the
`ticket purchaser loses the ticket and cannot receive the
`refund occurs. Since the ticket is deleted. even if the ticket
`purchaser attempts to make a claim for the ticket vender. a
`problem arises that there is no physical evidence.
