To maintain the privacy of individual users' personal data, a growing number of researchers propose storing user data in client computers or personal data stores in the cloud, and allowing users to tightly control the release of that data. While this allows specific applications to use certain approved user data, it precludes broad statistical analysis of(More)
Web-based enterprises process events generated by millions of users interacting with their websites. Rich statistical data distilled from combining such interactions in near real-time generates enormous business value. In this paper, we describe the architecture of Photon, a geographically distributed system for joining multiple continuously flowing streams(More)
Online advertising is a major economic force in the Inter-net today. Today's deployments, however, erode privacy and degrade performance as browsers wait for ad networks to deliver ads. In this paper we pose the question: is it possible to build a practical private online advertising sys-tem? To this end we present an initial design where ads are served(More)
Online tracking of users in support of behavioral advertising is widespread. Several researchers have proposed non-tracking online advertising systems that go well beyond the requirements of the Do-Not-Track initiative launched by the US Federal Trace Commission (FTC). The primary goal of these systems is to allow for behaviorally targeted advertising(More)
There are a number of designs for an online advertising system that allow for behavioral targeting without revealing user online behavior or user interest profiles to the ad network. However, none of the proposed designs have been deployed in real-life settings. We present an effort to fill this gap by building and evaluating a fully functional prototype of(More)
The method of the wounds treatment, using apparatuses for their edges rapprochement, was elaborated, basing on analysis of clinico-experimental investigations conducted. The method was successfully applied for the wounds closure after excision of coccygeal channel, the soft tissues abscess and phlegmon, postoperative ligature fistula and in temporary(More)
Changes in the cell immunity indexes under the influence of thymalin, thyroxin and fibronectin in vitral loading models were studied up in patients with hyperplastic diseases of the thyroid gland. Disbalance of the cell link immunity was revealed before the operation and, in particular, in the main subpopulations of lymphocytes as well as immunoregulating(More)
