The battery module 8 is located inside the identity card body 1 near the back and is electrically connected to the embedded chip module 2 and other functional modules through a power management circuit to power the entire system.

[0028] Specifically, the embedded chip module 2 includes a security encryption unit, an identity information storage unit, and a blockchain communication processing unit. The embedded chip module 2 exchanges data with the fingerprint recognition sensor 3 through a dedicated bus and connects to the display screen 4 for video signal transmission through a display control interface. The security encryption unit is used to store private keys and execute encryption algorithms. The identity information storage unit is used to locally store user IDs, permission levels, etc. The blockchain communication processing unit is responsible for communicating with blockchain nodes and completing functions such as identity authentication and event logging.

[0029] The fingerprint sensor 3 is equipped with an independent biometric processing unit, which establishes a connection with the embedded chip module 2 through the SPI communication protocol. It is used to send the collected fingerprint template data to the embedded chip module 2 for verification. The fingerprint sensor 3 can quickly and accurately complete user identity verification, which is more difficult to forge than traditional IC cards or passwords, thus improving the overall security level of the system.

[0035] Working principle

[0036] This embodiment provides a blockchain-based anti-counterfeiting electronic conference identity card. Its overall working principle is based on an embedded system control architecture, combining biometrics, near field communication (NFC), wireless network connection, and blockchain technology to build a highly secure and traceable intelligent identity authentication and data interaction platform. The identity card uses an embedded chip module 2 as its core control unit, responsible for coordinating data exchange and operation control between various functional modules. During user use, the fingerprint sensor 3 first collects the user's fingerprint information, and the security encryption unit inside the embedded chip module 2 compares and verifies the fingerprint template to ensure the authenticity of the user's identity. After successful verification, the embedded chip module 2 retrieves the stored identity information and, in conjunction with the blockchain communication processing unit, generates a corresponding identity authentication request. This request is then sent to the internet via the wireless network module 6 to achieve data synchronization and verification with a cloud server or blockchain node, thus forming an immutable identity record. Simultaneously, users can view their current identity status, meeting schedules, and other information via the OLED touchscreen display 4 and interact with the system through touch. At the meeting, the NFC module integrated on the back of the identity card enables contactless communication with a reader / writer, facilitating quick check-in or permission verification and improving efficiency. Furthermore, the wireless network module 6 supports Wi-Fi and Bluetooth Low Energy communication, allowing the identity card to upload meeting participation data to the central server or local gateway in real time, further enhancing the management capabilities of the backend system. (USB) The Type-C interface is used for charging and wired data transmission with external devices, ensuring the continuous operation and maintenance upgrades of the equipment. The entire system is powered by a built-in lithium polymer battery, and the power management integrated circuit (PMIC) efficiently regulates the power supply of each module to ensure low power consumption and long battery life. Overall, this blockchain-based anti-counterfeiting electronic meeting identity card integrates multimodal authentication mechanisms, multi-level encryption protection, blockchain evidence storage technology, and multiple communication methods to achieve a secure, intelligent, and convenient electronic identity authentication solution, suitable for various meeting and industry application scenarios that require high-security identity management.
