Information is written to the reading means 32 of the interphone 7 by the interphone information writing means 30 of the interphone supplier side server 5.
The information stored in the storage unit 26 of the employee card 6 is read by the transmission / reception unit 24 of the employee card 6 and the transmission / reception unit 33 of the intercom 7.

  Note that the storage medium for the courier used in the present invention can use various known storage media in addition to known non-contact IC cards as employee cards, and storage means such as a mobile phone. You may use the medium which has.

Next, the delivery company identification method according to the embodiment of the present invention will be described with reference to FIGS.
First, a request for key issuance is requested from the intercom provider server 5 to the certificate authority server 2 via the communication line 1. (Step S1)
The certificate authority server 2 generates a first private key and a first public key that can be used as a pair based on the received key issuance application, and the pair of the first private key and the first public key are transmitted to the intercom provider side. It transmits to the server 5. (Step S2)

In addition, a request for key issuance request is made from the delivery company side server 3 to the certificate authority server 2 via the communication line 1. (Step S3)
The certificate authority server 2 generates a pair of second secret key and second public key that can be used as a pair based on the received key issuance application, and sends the pair of second secret key and second public key to the delivery company side. It transmits to the server 3. (Step S4)

Next, the first secret key is transmitted from the intercom provider side server 5 to the employee card issuing device 4 via the communication line 1. (Step S5)
When the first secret key is sent from the intercom provider side server 5 side to the employee card issuing device 4 side, the first secret key is temporarily stored in a storage medium, and the storage medium is stored on the employee card issuing device 4 side. May be sent to or witnessed delivery.
Further, the delivery company side server 3 through the communication line 1 to the employee card issuing device 4 has a pair of second secret key and second public key, and an employee specific of the delivery company employee who performs the employee card. Send information. (Step S6)

Next, the employee unique information signature data generation means 18 generates employee unique information signature data obtained by encrypting the employee unique information using the second secret key. (Step S8)
Then, the generated home delivery company public key certificate, employee specific information signature data, and employee specific information are transmitted from the transmission / reception means 21 of the employee card issuing device 4 to the transmission / reception means 24 of the employee card 6. Then, it is stored in the storage means 25 of the employee card 6. (Step S9)

The employee card 6 created as described above is delivered and issued to the employee 38 of the delivery company.
The employee of the delivery company carries this employee card 6 when delivering the delivery to the recipient and uses it when performing authentication processing.

Next, a process when the employee 38 of the delivery company visits to deliver the delivery to the recipient's house 39 of the delivery will be described with reference to FIGS.
When an employee of the delivery company arrives at the recipient's house 39, the employee 38 brings the employee card 6 closer to the interphone 7 and the delivery company public key certificate stored in the storage means 26 of the employee card 6 And the employee unique information signature data and the employee unique information are read by the intercom 7. (Step S10)
The storage device 34 of the intercom 7 has already stored the first public key, and the second public key is obtained by decrypting the courier public key certificate read from the employee card 6 with the first public key. obtain. (Step S11)

Next, the authentication processing means 35 of the interphone 7 decrypts the employee unique information signature data read from the employee card 6 by using the second public key obtained by decrypting with the first public key. (Step S12)
Further, the interphone 7 performs collation processing between the employee unique information obtained from the decrypted employee unique information signature data and the employee unique information read from the employee card 6. (Step S13)

As a result of the collation processing, if the collation is coincident, the authentication is approved, and the call means 36 is controlled to be able to make a call. (Step S14)
If the collation does not match as a result of the collation process, the authentication is not approved, and the call is terminated while the call means 36 cannot make a call.
Therefore, even if a third party makes an unauthorized visit while posing as an employee of the delivery company, he / she cannot make a call with the resident of the visitor's house so that he / she can not do wrong.
