Privacy-preserving behavior targeting for digital coupons

摘要

A smart coupon-delivery system provides targeted coupons to a user using a criteria-encoded message received from a coupon server. The criteria-encoded message is generated by the coupon server from a behavior-criteria vector that indicates criteria for selecting a recipient of a digital coupon. The system then generates a user-behavior vector to indicate one or more behavior patterns of an end-user, and encodes the user-behavior vector to produce a behavior-encoded message. The system then determines whether the end-user is eligible to receive the digital coupon based on the criteria-encoded message and the behavior-encoded message. If the system determines that the end-user is eligible, the system presents the digital coupon to the end-user.

主权项

1. A computer-implemented method comprising:
receiving, by a computing device, a criteria-encoded message that encodes criteria for selecting a recipient of a digital coupon; generating, by the computing device, a user-behavior vector that includes one or more vector entries, wherein a respective vector entry includes a numeric value that characterizes a user behavior for the end-user; producing, by the computing device, a behavior-encoded message that encodes the end-user's behavior pattern, wherein producing the behavior-encoded message involves using a hash function to encode the user-behavior vector; determining, by the computing device, that the end-user is eligible to receive the digital coupon in response to detecting a match between the criteria-encoded message and the behavior-encoded message; and providing, by the computing device, the digital coupon to the end-user in response to determining that the user is eligible.
