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.

System of anonymous user creation based on oblivious transfer

Anonymously providing purchasing analytics associated with customer to a website while the customer is accessing the website. Specifically, a financial institution, having access to a customer's transactional data, can analyze the data to determine analytical purchasing data. Once the customer authenticates themselves at a financial institution website, a networked application or the like, an anonymous cookie that is configured to identify the analytical purchasing data is generated and stored in the web browser cache. In response to the customer using the device to access a website that displays advertisements, the anonymous cookie is retrieved from the web browser cache and the analytical purchasing data is provided to the website. In specific embodiments of the invention, the website uses the analytical purchasing data of the customer to determine which of the plurality of advertisements are to be displayed to the customer while they visit the website.

Serving anonymous cookies associated with purchasing analytics

The tool to provide anonymous data in response to a request for information is configured to receiving a request for information relating to a population of interest from a user; determining criteria associated with the population of interest, wherein the criteria define an individual representative of the population of interest; determining a characteristic of the individual within one or more categories; classifying the characteristic of the individual into a cluster, the cluster comprising a subset of all possible outcomes for the category; classifying a plurality of individuals from a database into clusters based on the one or more categories; determining a subset of the plurality of individuals that are similar to the individual representative of the population of interest based on the clusters; transforming the characteristics of the individuals in the subset to generate anonymous data responsive to the request for information; and providing the anonymous data to the user.
