AI Technical Summary
Technical Problem
Existing authentication methods for card-type recording media, such as IC cards and credit cards, are vulnerable to counterfeiting, allowing malicious actors to access servers and potentially leak confidential information.
Method used
The card-type recording medium records confidential information magnetically or electronically and an encryption key optically and invisibly, using SERS nanotags with unique Raman shifts, which are read by a terminal to authenticate the card's authenticity before allowing server access.
Benefits of technology
This approach makes counterfeiting the card-type recording medium impossible and prevents unauthorized server access by ensuring the encryption key's uniqueness and invisibility, thus enhancing security.

Abstract
We provide an authentication system using a card-type recording medium that makes forgery virtually impossible and prevents unauthorized access to servers. [Solution] An authentication system comprising: a card-type recording medium on which confidential information is recorded magnetically or electronically, and on which an encryption key is recorded separately from the confidential information in an optically readable and invisible manner; a terminal capable of reading the confidential information; and a server that rejects login requests from the terminal unless the confidential information matches predetermined registered confidential information. The terminal device has a reader for reading the encryption key, and if the encryption key does not match a predetermined registered encryption key, it rejects the login request from the terminal device.
