摘要： Embodiments of the disclosure provide a recognition method, apparatus, device, and storage medium and relates to the field of artificial intelligence technology. The method includes obtaining a second decision-making threshold of a feature-matching model in a target scenario by joint testing of the feature-matching model and auxiliary detection model. The method takes into full consideration the mutual influence between different algorithm models in a scenario when multiple algorithm models are used for facial recognition. Compared to manually setting a decision-making threshold for each algorithm model independently, the methods in the disclosure are more adaptable to changing scenarios and scenarios with multiple models used in facial recognition. This improves the accuracy and efficiency of the obtained decision-making thresholds, thereby enhancing the accuracy of multi-model facial recognition.

摘要： An electronic device and a trusted application calling method are provided. After a client application initiates call information, a trusted application development platform receives the call information, determines a native trusted application corresponding to first identification information of the electronic device carried by the calling information from native trusted applications corresponding to at least two (or more) TEE OSs connected to the trusted application development platform, and sends the calling information to the native trusted applications corresponding to the first identification information. The native trusted application corresponding to the first identification information receives the calling information, determines a bytecode trusted application corresponding to the second identification information from at least one bytecode trusted application installed in the native trusted application according to the second identification information carried by the calling information, and calls the bytecode trusted application corresponding to the second identification information.

摘要： A blockchain consensus method includes: an accounting node generating a block and broadcasting verification information of the accounting node to other accounting nodes among N accounting nodes; receiving and verifying acknowledgement information broadcast by the other accounting nodes; and adding the block to a blockchain when the received acknowledgement information satisfies a second set condition. The N accounting nodes are determined according to coin age information carried in election requests broadcast by M election nodes. The acknowledgement information broadcast by the other accounting nodes is generated and broadcast by a first accounting node when received preparation information of a second accounting node meets a first set condition; the preparation information of the second accounting node is generated and broadcast by the second accounting node when validating the verification information; and each of the first accounting node and the second accounting node is any one of the other accounting nodes.
