Detection of content display observers with prevention of unauthorized access to identification signal
First Claim
1. A system for identifying a content observer who views a content display device at a content display site, comprising:
- a sensor for acquiring data regarding an aspect of the environment of the content display device, wherein the presence of the content observer in the vicinity of the content display device when the content observer is observing the content display device can be detected from the data acquired by the sensor;
means for processing the data acquired by the sensor to produce data identifying the content observer; and
means for preventing unauthorized access to the data acquired by the sensor and/or the data produced by the processing means;
wherein the means for preventing unauthorized access comprises a filter configured to ensure that only a subset of the acquired data that was or could have been used by the processing means to produce data identifying the content observer and/or only a subset of the produced data identifying the content observer is stored;
whereby the content observer'"'"'s privacy is protected by limiting the amount of acquired and/or produced data that is stored and potentially subject to being accessed without authorization.

Abstract
The invention enables and/or facilitates the display of personalized content to content observers by content providers (e.g., advertisers) who disseminate content over a network. The invention enables identification of particular content observers at a content display site using analysis of content observation behavior at a content display site, data regarding one or more physical characteristics of content observers in the vicinity of the content display device during display of particular content, and/or analysis of demographic characteristics of possible content observers at the content display site. The invention prevents unauthorized access to data produced as part of identification of the content observer.
