"Second Generation U Shield" is an upgraded product of U Shield, which is a kind of physical hardware with intelligent chip and similar appearance to flash memory (U disk) and LCD screen. If online banking customers need to handle external payment business, they need to insert the "U shield" into the USB interface of the computer, enter the password, and complete the payment after repeated verification by the banking system. Compared with ordinary U-Shield, the second-generation U-Shield mainly adds "Confirm" and "Cancel" buttons, as well as an LCD screen to display the transaction amount and account number.
When the customer handles payment and other services through online banking, the LCD screen on the second generation U shield will automatically echo the transaction amount, account number and other information. After the customer confirms that it is correct, press the "Confirm" button to complete the transaction. This innovative design of "customer check and sign for confirmation" can make customers use it more intuitively and safely.
The first generation of USBKey solved the problem of secure storage of digital certificates, but it could not prevent hackers from illegally calling through remote control. Tiandi Rong Company first proposed to add key confirmation, voice prompt or screen display check components to USBKey-we called it "HIP human-computer interaction" security solution, which physically cut off the hacker attack channel.
