Black Label's security solution is a mutual verification system, which is a personal identification security solution through mutual verification between SIM and identity authentication server. Among existing wireless communication networks, a mobile communication network using a USIM, which is a personal identification device, is considered to be most secure against hacking. This is because the USIM card has a personal identification code, including the user's mobile communication number, so it sends and receives a telephone call or message after authentication. BLACK LABEL has developed a security solution called "Mutual Verification System" by utilizing the characteristics of SIM and enhancing the disadvantages of the personal identification process to enhance the personal identification security.
The mutual verification system is a system that sends and receives personally identifiable information to the authentication server by infinitely changing the initial personal identification code without a pattern through SIM's MCU. The biggest problem in existing personal identification security systems is that security information is a single code. While a single code can be hacked and replicated when exposed to authentication information, the black label is designed to transmit an infinite change without pattern every time the MCU and the identity authentication server tag the individual identification code. Also, it is not meaningful to change the used variable code so that it is discarded and not rewritten.
