    Digital Content Next January 2018 / DCN Distributed Content Revenue Benchmark Google Data Collection —NEW— August 2018 digitalcontentnext.org CONFIDENTIAL - DCN Participating Members Only 1 This research was conducted by Professor Douglas C. Schmidt, Professor of Computer Science at Vanderbilt University, and his team. DCN is grateful to support Professor Schmidt in distributing it. We offer it to the public with the permission of Professor Schmidt. Google Data Collection Professor Douglas C. Schmidt, Vanderbilt University August 15, 2018 I. EXECUTIVE SUMMARY 1. Google is the world’s largest digital advertising company.1 It also provides the #1 web browser,2 the #1 mobile platform,3 and the #1 search engine4 worldwide. Google’s video platform, email service, and map application have over 1 billion monthly active users each.5 Google utilizes the tremendous reach of its products to collect detailed information about people’s online and real-world behaviors, which it then uses to target them with paid advertising. Google’s revenues increase significantly as the targeting technology and data are refined. 2. Google collects user data in a variety of ways. The most obvious are “active,” with the user directly and consciously communicating information to Google, as for example by signing in to any of its widely used applications such as YouTube, Gmail, Search etc. Less obvious ways for Google to collect data are “passive” means, whereby an application is instrumented to gather information while it’s running, possibly without the user’s knowledge. Google’s passive data gathering methods arise from platforms (e.g. Android and Chrome), applications (e.g.

  • The Pii Problem: Privacy and a New Concept of Personally Identifiable Information
    \\jciprod01\productn\N\NYU\86-6\NYU603.txt unknown Seq: 1 28-NOV-11 15:01 THE PII PROBLEM: PRIVACY AND A NEW CONCEPT OF PERSONALLY IDENTIFIABLE INFORMATION PAUL M. SCHWARTZ† & DANIEL J. SOLOVE‡ Personally identifiable information (PII) is one of the most central concepts in information privacy regulation. The scope of privacy laws typically turns on whether PII is involved. The basic assumption behind the applicable laws is that if PII is not involved, then there can be no privacy harm. At the same time, there is no uniform definition of PII in information privacy law. Moreover, computer science has shown that in many circumstances non-PII can be linked to individuals, and that de-identified data can be re-identified. PII and non-PII are thus not immutable categories, and there is a risk that information deemed non-PII at one time can be transformed into PII at a later juncture. Due to the malleable nature of what consti- tutes PII, some commentators have even suggested that PII be abandoned as the mechanism by which to define the boundaries of privacy law. In this Article, we argue that although the current approaches to PII are flawed, the concept of PII should not be abandoned. We develop a new approach called “PII 2.0,” which accounts for PII’s malleability. Based upon a standard rather than a rule, PII 2.0 utilizes a continuum of risk of identification. PII 2.0 regulates informa- tion that relates to either an “identified” or “identifiable” individual, and it estab- lishes different requirements for each category.

An overview on currently know security threats for RFID systems, countermeasures and related cost aspects is given. This is followed by a brief overview on current areas of application for RFID. To put a light on status quo and trends of development in the private sector in the context of RFID, the results of a study carried out in 2004 and 2005 in Germany are summarised. This is followed by an overview on relevant standards in the context of RFID. This deliverable also includes a bibliography containing relevant literature in the context of RFID.
