US 2024/0403476 A1 · Privacy-Preserving Recommendation Generation

Abstract

A computing device provides a user recommendation according to one or more privacy protocols. The computing device sends to a server one or more encrypted recommendation requests for recommendation information relating to a set of items, where the recommendation requests are encrypted by a cryptographic key not accessible to the server. The server uses the encrypted recommendation requests and a recommendation data store to generate one or more encrypted recommendation responses that it returns to the computing device using at least one of the privacy protocols, which prevents the server from accessing the encrypted recommendation request and recommendation response. The computing device receives from the server the encrypted recommendation responses relating to the set of items and decrypts the recommendation responses. Then, the computing device generates a user recommendation relating to the set of items from the decrypted recommendation responses and provides the recommendation to the user.

Claims20

Dependent claims

An apparatus, comprising:

a processor circuit;
and
a memory storing instructions executable by the processor circuit to cause the apparatus to perform operations comprising:
communicating with a computer server according to one or more privacy protocols, wherein the communicating includes:
sending, to the computer server, one or more encrypted recommendation requests relating to a set of items;
and
receiving, from the computer server, one or more encrypted recommendation responses, wherein the one or more privacy protocols prevent the computer server from accessing unencrypted versions of 1) the one or more encrypted recommendation requests and 2) the one or more encrypted recommendation responses;
decrypting, by the apparatus, the one or more encrypted recommendation responses to produce a set of decrypted recommendation response data;
generating a user recommendation relating to the set of items, wherein the generating uses the set of recommendation response data;
and
providing the user recommendation to the user.

8 more elements

A non-transitory computer-readable medium having program instructions stored therein that are executable by a computing device to perform operations comprising:

communicating with a computer server according to one or more privacy protocols, wherein the communicating includes:
sending, to the computer server, one or more encrypted recommendation requests relating to a set of items;
and
receiving, from the computer server, one or more encrypted recommendation responses, wherein the one or more privacy protocols prevent the computer server from accessing unencrypted versions of 1) the one or more encrypted recommendation requests and 2) the one or more encrypted recommendation responses;
decrypting the one or more encrypted recommendation responses to produce a set of decrypted recommendation response data;
generating a user recommendation relating to the set of items, wherein the generating uses the set of decrypted recommendation response data;
and
providing the user recommendation to the user.

5 more elements

A method, comprising:

communicating, by a computing device, with a computer server according to one or more privacy protocols, wherein the communicating includes:
sending, to the computer server, one or more encrypted recommendation requests relating to a set of items;
and
receiving, from the computer server, one or more encrypted recommendation responses, wherein the one or more privacy protocols prevent the computer server from accessing unencrypted versions of 1) the one or more encrypted recommendation requests and 2) the one or more encrypted recommendation responses;
decrypting, by the computing device, the one or more encrypted recommendation responses to produce a set of decrypted recommendation response data;
generating, by the computing device, a user recommendation relating to the set of items, wherein the generating uses the set of decrypted recommendation response data;
and
providing, by the computing device, the user recommendation to the user.
