Embodiment approach

[0193] It should be understood that appropriate hardware, software, or a combination of hardware and software is provided at the location of the user equipment and at the location of the service provider (typically, but not necessarily, far away from the user equipment). The process described in the various embodiments of the present invention above is made effective. It should also be appreciated that certain embodiments of the invention may support one or more of the operating modes described herein, but not necessarily all of these operating modes.

[0194] Although the embodiments of the present invention are described here in the context of a "user" as a single person using a single "user device" in a given household, it is likely that more than one person will share Internet connections and connections with other individuals in the same household. / Or TV service (or, similarly, for example, more than one worker in a commercial establishment will share an Internet connectio...

Abstract

A distribution and scheduling system for advertisements that targets ads to users and maximizes service-provider revenue without having full knowledge of user-profile information. Each user device stores a user profile and is pre-loaded with a set of ads that could possibly be shown during a timeslot. Each user device selects and displays an ad based on the user profile but does not identify the selected ad to the service provider. Instead, the user devices provide perturbed user-profile information in the form of Boolean vectors, which the service provider uses in conjunction with a guaranteed-approximation online algorithm to estimate the number of users that saw a particular ad. Thus, the service provider can charge advertisers for the number of times their ads are viewed, without knowing the users' profiles or which ads were viewed by individual users, and users can view the targeted ads while maintaining privacy from the service provider.

Description

Technical field [0001] The present invention generally relates to the field of targeted advertising (or "ad") for television, web browsing and other media, and in particular to an ad distribution and scheduling system, which keeps user profile information private At the same time, the target of ad is determined to the user. Background technique [0002] This section introduces aspects that can help promote a better understanding of the invention. Therefore, reading the narratives in this section in this context, these contents are not construed as confirming existing technology and non-existing technology. [0003] Effectively determine the goal of ad to the user has become an increasingly important revenue-generating service. In order to more appropriately and accurately determine the target, the service provider must have access to the user's interest profile. Google’s AdWords as the forerunner of ad targeting technology initially started with the service of determining ad tar...
