Model-based data generation method and device, computer equipment and storage medium

The invention relates to the technical field of artificial intelligence, and provides a model-based data generation method and device, computer equipment and a storage medium. The method comprises the steps: receiving an operation index data obtaining request; acquiring user information, a first palmprint image, a first palmprint vein image and a face image of the user, and performing identity verification on the user based on the expression recognition model and the palm recognition model; if the identity verification is passed, acquiring a first data table corresponding to the operation index identifier; calculating the data of the first data table based on the calculation rule of the operation index to obtain result data; and synchronizing the result data to a second data table in the column storage database to obtain a target data table. According to the method, the target data table containing the result data of the operation indexes can be automatically and quickly generated. The method can also be appl
