Abstract
Bridging encrypted datasets is provided. A system transmits, to a server, a first identifier vector encrypted with a first encryption that is commutative. The system receives an encrypted first identifier vector encrypted based on the first encryption and encrypted by a second encryption associated with the server. The system receives a second identifier vector encrypted based on the second encryption. The system encrypts the second identifier vector with the first encryption to generate an encrypted second identifier vector that is encrypted based on the second encryption and further encrypted based on the first encryption. The system determines a correlation count between the encrypted first identifier vector and the encrypted second identifier vector. The system generates one identifier key for both the first identifier and the second identifier. The system can provide the one identifier key for input into an application to process interactions.
