Abstract
This application relates to a node group-based data processing method performed by a first node in the node group, and includes: constructing, according to a first user identifier, a mapping relationship for mapping the first user identifier to a target value; performing homomorphic encryption on a mapping parameter of the mapping relationship, to obtain a mapping parameter ciphertext, and transferring the mapping parameter ciphertext to the second node in the node group; receiving the reference value and the fragment information returned by the second node; and maintaining, when a result obtained after homomorphic decryption is performed on the reference value is consistent with the target value, the fragment information returned corresponding to the reference value, and triggering the first node to collect fragment information maintained in each first node, to aggregate the collected fragment information to obtain a user identifier intersection set of the node group.
