Smart Card Security for Mobile Payment Systems
Here’s PatSnap Eureka !
Summary
Problems
Existing contactless IC card technologies, particularly in mobile devices, lack security measures to prevent unauthorized use of electronic payment functions, leading to theft risks when the device is lost or the battery is dead.
Innovation solutions
Incorporating a smart card with integrated security functions and an authentication unit that requires a password for authorization, allowing the electronic payment function to operate independently of the device's power status and enabling secure transfer of authentication data to new devices.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If the security IC is fixed in the mobile phone, then the electronic payment function can be implemented, but the authentication data cannot be transferred to a new mobile phone when changing devices
Why choose this principle:
The patent separates the authentication data storage from the mobile phone device by using a removable smart card. The security function is segmented into an independent card that can be transferred between devices, while the mobile phone provides the processing capability. This allows authentication data to be portable while maintaining system functionality.
Principle concept:
If the security IC is fixed in the mobile phone, then the electronic payment function can be implemented, but the authentication data cannot be transferred to a new mobile phone when changing devices
Why choose this principle:
The smart card acts as an intermediary carrier for authentication data between different mobile phones. Instead of fixing the security IC to one phone, the card serves as a portable mediator that can be inserted into different devices, enabling data transfer while maintaining security.
