Abstract
Embodiments of the invention include systems, methods, and computer-program products for anonymizing a user utilizing oblivious transfer. In this way, the invention establishes a common index to identify members of a population sample, anonymizes the identities of sample members to each party, and exchanges statistics and characteristics of the sample population. The invention creates a common searchable index and anonymizes the sample members of the database via encryption of identification of individual customers in each sample. Each encryption provides for a strong encryption with a key and a homomorphic encryption. The homomorphic encryption allows for multiplication and/or addition on ciphertexts that, once decrypted, match the result that would have occurred had the operations been carried out on the plaintext. In some embodiments, the encryption may be either partially- or fully-homomorphic cryptosystems.
