Wi-Fi is one of the wireless LAN communication standards according to the IEEE 802.11 standard. USB is a serial bus communication standard, and Lightning is also one of the wired communication standards.

It is preferable that the smartphone 10 has a biometric authentication function such as fingerprint authentication. When the smartphone 10 has a biometric authentication function, the lock can be easily released without inputting the PIN code every time, and the convenience can be improved while ensuring the security of the smartphone 10. The biometric authentication method of the smartphone 10 is not limited to fingerprint authentication, and may be face authentication, iris authentication, or the like.

A dedicated application program (fingerprint authentication application) linked with the fingerprint authentication function of the smartphone case 20 is installed in the smartphone 10 according to the present embodiment. Further, the third-party application program 12 can verify the identity by using the program module 13 (fingerprint authentication program module) linked with the fingerprint authentication function of the smartphone case 20.

The smartphone case 20 is a cover member for protecting the smartphone 10 from impacts and the like. While the smartphone 10 is a precision device and is vulnerable to impacts such as dropping, it is small and thin and easy to drop. Therefore, most smartphone users use the smartphone 10 by housing it in the smartphone case 20.

At this time, the LED indicator 27 also blinks.

When the user who receives the request for the fingerprint reading operation on the smartphone 10 presses his / her fingertip against the fingerprint sensor 21 of the smartphone case 20 to perform the fingerprint reading operation (step S5), the fingerprint data collation process is performed. The fingerprint authentication result data is transferred to the smartphone 10 (step S6).

When the fingerprint authentication result data indicates that the authentication is successful, the request for operating the application program is approved and the smartphone 10 is unlocked, so that the application program can be operated (step S7A). However, if the fingerprint authentication result indicates an authentication failure, the request for operating the application program is rejected and the lock of the smartphone 10 is not released, so that the application program cannot be operated (step S7B).

When the smartphone 10 requests the service server 30 for electronic payment, the application program of the smartphone 10 transmits the fingerprint authentication result data sent from the smartphone case 20 to the service server 30. When the smartphone 10 has a biometric authentication function, both the biometric authentication result by the smartphone 10 and the fingerprint authentication result by the smartphone case 20 are transmitted to the service server 30.

Then, when the fingerprint authentication result indicates that the authentication is successful, the service server 30 executes a desired electronic payment process. If the fingerprint authentication result indicates successful authentication, the desired electronic payment process is executed. Therefore, the reliability of electronic payment can be improved.

When the smartphone 10 itself has a biometric authentication function, the biometric authentication result by the smartphone 10 can be sent to the service server 30 together with the fingerprint authentication result by the smartphone case 20. In this case, the service server 30 can perform the desired electronic payment process only when both of them are successfully authenticated. When double biometric authentication is performed in this way, the reliability of electronic payment can be enhanced, and the security of high-value payment can be enhanced.

Since the smartphone 10 is a multifunctional and very expensive information device, the owner must be changed, and if the smartphone 10 has a biometric authentication function, the biometric information can be rewritten. .. Normally, the biometric information can be rewritten by inputting a personal identification code such as a PIN code to unlock it. Therefore, if the password code is known to a third party, the biometric information may be rewritten and the smartphone 10 may be hijacked, and the third party can impersonate the owner of the smartphone 10. ..

However, even if a third party can rewrite the biometric information in the smartphone 10 and impersonate the person, the fingerprint authentication on the smartphone case 20 side cannot be breached. Therefore, it is possible to prevent unauthorized use of the smartphone 10 by a third party, and it is possible to enhance the security of the smartphone 10 and the security of various cloud services provided via the smartphone 10. Further, when the smartphone case 20 is provided with the fingerprint authentication function, the fingerprint authentication function can be added to the smartphone 10 simply by accommodating the smartphone 10 in the smartphone case 20, so that the additional fingerprint authentication function is always added to the smartphone. It can be carried with the 10 and can improve convenience.

As described above, in the authentication system 1 according to the present embodiment, the smartphone case 20 accommodating the smartphone 10 has a fingerprint authentication function and a communication function, and the identity verification is performed using the fingerprint authentication result of the smartphone case 20. Even if the smartphone 10 is not equipped with the biometric authentication function, it is possible to carry out identity verification by biometric authentication, and it is possible to enhance the security of the smartphone 10. Further, when the biometric authentication function is implemented in the smartphone 10, spoofing by rewriting the biometric information in the smartphone 10 can be prevented, and the security can be further improved by the additional authentication. Therefore, it is possible to prevent unauthorized use of the smartphone by a third party other than the legitimate owner.
