Feature synchronization method, computer device, and storage medium

A computer device, comprising one or more processors and a memory containing computer-readable instructions that, when being executed, cause the one or more processors to implement:

• receiving a feature synchronization request, the feature synchronization request carrying an iris feature and a first version number of the iris feature;
• determining, through the first filter based on the iris feature and the first version number, a first numerical position corresponding to the feature synchronization request in the first filter, a numerical value at the first numerical position representing whether the iris feature has an updated version in the iris feature library;
• accessing the iris feature library through the first filter when the numerical value at the first numerical position represents that the updated version of the iris feature exists in the iris feature library, and obtaining the updated version of the iris feature through the iris feature library;
• and
• delivering the updated version of the iris feature to a request sender of the feature synchronization request for the request sender to store the updated version of the iris feature.

A non-transitory computer-readable storage medium containing computer-readable instructions that, when being executed, cause the one or more processors to implement:
