The utility model provides an active visual intelligent card, comprising an intelligent card security chip used for realizing non-contact transaction, the intelligent card security chip comprises a processor, a security module and a storage unit, the security module is used for security communication and generating a secret key, and the secret key is stored in the storage unit; the key module is used for converting key operation into a switching value signal and inputting the switching value signal to the intelligent card security chip, and the intelligent card security chip is used for realizing corresponding control according to the switching value signal; data connection is established between the electronic ink screen and the smart card security chip, and page data of the electronic ink screen is input to the smart card security chip through a non-contact interface; the RTC clock module is used for providing a reference time signal for the smart card security chip. According to the utility model, the intelligent card security chip is adopted to realize human-card interaction control and ensure the security performance of the intelligent card, so that the effects of realizing human-card interaction, reducing master control, reducing card manufacturing cost and power consumption, and being simple in structure, relatively small in occupied volume and high in security are achieved.

Wireless communication technologies, a dynamic transaction card, and a mobile application may be utilized to facilitate multi-factor authentication and secure electronic checkout of any website. A wireless connection between a dynamic transaction card and a user device may be utilized to authenticate a user. A user device application may be triggered to call, via an application programming interface (API), an account provider system, and this unique pairing may automatically facilitate payment to a merchant system associated with the electronic check out page. The account provider system may send a push notification to a browser extension associated with the checkout page to prompt the browser extension to populate fields on the electronic checkout page using user account information transmitted from the account provider system, providing a novel digital authentication framework that utilizes digital authentication techniques enables by user devices and dynamic transaction cards to seamlessly facilitate electronic checkout.

The invention relates to the technical field of intelligent card communication, in particular to an intelligent card safety communication system based on NFC and digital identity integration, and the system comprises an instruction generation management module, an instruction synchronization module, a failure marking module, a storage module and a verification module. The CA server completes the invalidation right confirmation of the digital identity and the CA certificate, generates a unique temporary revocation instruction and incorporates the unique temporary revocation instruction into a temporary revocation instruction pool; the CA server pushes to-be-synchronized instructions to the terminal in batches, the terminal issues the instructions to the smart card, a hardware-level failure mark is written into a security chip of the smart card, and the terminal stores the failure mark into a local failure cache library; before intelligent card communication, a terminal preferentially verifies a local cache library, and then judges the state through online query of an instruction pool or offline CRL and failure response dual verification according to the network state, so that failure card interception is realized. According to the invention, through hardware marking and hierarchical verification, the real-time invalidation of the intelligent card is ensured, and the multi-scene security requirements are met.

The invention relates to the technical field of smart card operating systems, and discloses a security test platform of a smart card operating system and a construction method and system thereof. The method comprises the following steps: constructing a preset attack model of an intelligent card operating system; formulating a security protection strategy according to a preset attack model, and integrating the security protection strategy into an intelligent card operating system; constructing a security test platform of the smart card operating system based on the security protection strategy; and carrying out attack simulation, data acquisition and result analysis according to the security test platform to test the security of the smart card operating system. According to the invention, the security research of the intelligent card operation system is deeply developed, the attack method is comprehensively analyzed to construct the preset attack model, the practical and effective security protection strategy is elaborately designed, and the professional security test platform is constructed, so that the security application of the intelligent card is ensured.
