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.

The present application discloses a method, an apparatus, and a device for updating a feature vector database, and a medium. The method includes: acquiring a first biological feature in a service request; obtaining, according to the first biological feature, a first feature vector and a second feature vector respectively through a first algorithm model and a second algorithm model, in which a first feature vector database include sample feature vectors obtained based on the first algorithm model; performing validity verification on the second feature vector according to an associated feature vector for a first user corresponding to a first sample feature vector; and obtaining, under a condition that the validity verification on the second feature vector passes, a second sample feature vector for the first user based on the second feature vector, and storing the second sample feature vector in a second feature vector database.

Embodiments of the present disclosure provide a method and apparatus for configuring a security carrier, including: adding a carrier batch field to a security carrier list, encoding, for each security carrier in the security carrier list, a plurality of pieces of batch feature information of the security carrier according to a preset encoding rule, so as to generate carrier batch information of each security carrier, and to add same to the security carrier list; and then, according to identifier information and the carrier batch information of each security carrier, configuring a supplementary security domain, a card application, an application installation package and an application provider that need to be preset for each security carrier. Since the carrier batch information contains a plurality of pieces of batch feature information of the security carrier, security carriers in the security carrier list can be effectively distinguished according to the identifier information and the carrier batch information of the security carriers, thus a plurality of preset items that need to be preset for a plurality of security carriers having the same carrier batch information can be configured, so as to improve configuration efficiency for the security carriers.

A method, terminal and device for establishing security infrastructure, comprising: an intermediate service organization receives an organization secret key sent by a third-party service organization; the intermediate service organization encrypts the organization secret key by a first encryption means and sends the encrypted organization secret key to a security storage region of a terminal; the intermediate service organization receives a first terminal public key encrypted by the terminal using a second encryption means; and the intermediate service organization sends the first terminal public key obtained by decryption to the third-party service organization. The organization secret key of the third-party service organization may be sent to the terminal through the intermediate service organization, and the first terminal public key of the terminal may be sent to the third-party service organization, thus a universal security infrastructure and a technical frame work having good openness may be provided by the intermediate service organization.

A statement parsing method for a database statement comprises: conducting lexical analysis on a database statement inputted into a database, to obtain an inputted word sequence; looking up a statement similarity table according to the inputted word sequence to determine whether there is an existing word sequence similar to the inputted word sequence in the statement similarity table; if yes, obtaining the parsed data corresponding to the existing word sequence from the statement similarity table; otherwise, parsing the inputted word sequence to obtain parsed data corresponding thereto, and storing the inputted word sequence and the corresponding parsed data in the statement similarity table; and executing the database statement inputted to the database based on the parsed data corresponding to the existing or inputted word sequence. The method can quickly parse a database statement and is favorable for improving the response speed and the working efficiency of a database.
