Do Not Track a Nokia Browser Look
Do Not Track Nokia Browser Position - Vikram Malaiya Copyright: Nokia Corporation, 2011 Our understanding of Do Not Track (DNT) • DNT is a technology to enables users to opt out of third-party web tracking • No agreed upon definition of DNT. There are currently 3 major technology proposals for responding to third-party privacy concern. 1. Stanford University and Mozilla’s DNT HTTP Header technique. 2. Blacklist based technique such as Microsoft’s ‘Tracking Protection’ which is part of IE9 3. Network Advertising Initiative’s model of a per company opt-out cookie. Opt-out cookie approach is being promoted by Google. DNT as HTTP Header The Browser adds ‘DNT’/ ‘X-Do-Not-Track’ to its http header. The header is sent out to the server with every web request. This header acts as a signal to the server suggesting that the user wishes to opt out of tracking. Adoption: Firefox 4, IE9 DNT as HTTP Header • Pros: – Scope: Server could apply restrictions to all third party entities and tracking mechanisms – Persistent: No reconfiguration needed once set – Simple: Easy to implement on the browser side • Cons: – Only work as long as the server honors users preferences – No way to enforce national regulations/legislations to servers located beyond country boundaries Block(Black) List / Tracking Protection This is a consumer opt-in mechanism which blocks web connections from known tracking domains that are compiled on a list. First party Third party Adoption: ‘Tracking Protection’ in Internet Explorer 9 cy.analytix.com The downloadable Tracking allow Protection Lists enable IE9 xy.ads.com consumers to control what deny third-party site content can deny track them when they’re ads.tracker.com Tracking Protection online. -

Page 1 INFOSEC UPDATE 2006 -- June 19-20, 2006 01 Introduction Category 01 Introduction 2006-06-12 Introduction M. E. Kabay, PhD, CISSP WELCOME Welcome to the 2005 edition of the Information Security Year in Review (IYIR) project. In 1993 and 1994, I was an adjunct professor in the Institute for Government Informatics Professionals in Ottawa, Canada under the aegis of the University of Ottawa. I taught a one-semester course introducting information security to government personnel and enjoyed the experience immensely. Many of the chapters of my 1996 textbook, _The NCSA Guide to Enterprise Security_ published by McGraw-Hill were field-tested by my students. In 1995, I was asked if I could run a seminar for graduates of my courses to bring them up to date on developments across the entire field of information security. Our course had twenty students and I so enjoyed it that I continued to develop the material and teach the course with the NCSA (National Computer Security Association; later called ICSA and then eventually renamed TruSecure Corporation and finally CyberTrust, its current name) all over the United States, Canada, Europe, Asia and the Caribbean. After a few years of working on this project, it became obvious that saving abstracts in a WordPerfect file was not going to cut it as an orderly method for organizing the increasing mass of information that I was encountering in my research. -

Statement of Justin Brookman Director, Consumer Privacy Center for Democracy & Technology Before the U.S. Senate Committee O
Statement of Justin Brookman Director, Consumer Privacy Center for Democracy & Technology Before the U.S. Senate Committee on Commerce, Science, and Transportation Hearing on “A Status Update on the Development of Voluntary Do-Not-Track Standards” April 24, 2013 Chairman Rockefeller, Ranking Member Thune, and Members of the Committee: On behalf of the Center for Democracy & Technology (CDT), I thank you for the opportunity to testify today. We applaud the leadership the Chairman has demonstrated in examining the challenges in developing a consensus Do Not Track standard and appreciate the opportunity to address the continued insufficiency of self-regulatory consumer privacy protections. CDT is a non-profit, public interest organization dedicated to preserving and promoting openness, innovation, and freedom on the decentralized Internet. I currently serve as the Director of CDT’s Consumer Privacy Project. I am also an active participant in the Worldwide Web Consortium’s Tracking Protection Working Group, where I serve as editor of the “Tracking Compliance and Scope” specification — the document that purports to define what Do Not Track should mean. My testimony today will briefly describe the history of online behavioral advertising and the genesis of the Do Not Track initiative. I will then describe the current state of the World Wide Web Consortium’s efforts to create Do Not Track standards and the challenges going forward to implement Do Not Track tools successfully. I will conclude with my thoughts on the future of Do Not Track. and why I believe that this protracted struggle demonstrates the need for the fundamental reform of our nation’s privacy protection framework for commercial and government collection and use of personal information. -

I Can't Generalize a Whole Lot About the Maxthon Cloud Browser, Which Got
I can’t generalize a whole lot about the Maxthon Cloud Browser, which got a major upgrade to Version 4.x in a December preview and was officially released on February 25. Maxthon Cloud Browser versions are available for Windows, OS X, iOS and Android, and it’s designed to provide users with a seamless and unified user experience across multiple devices and platforms. I can’t speak to the Windows and Android versions, but I’m unevenly impressed with the OS X and iOS variants. I found myself quickly becoming a fan of the OS X version; it’s a lot like Google’s Chrome browser—very fast and slick with super-smooth performance—but more so. It incorporates pretty much everything I like about Chrome, such as an automatic Google Translate machine translation option. The iOS version isn’t bad, just not nearly as outstanding as the OS X version. Interestingly, that would be my assessment of Google Chrome for iOS compared with Chrome for OS X, as well, and I think the reason in both instances is Apple’s imposition on its own WebKit technology on iOS browsers. Using Maxthon Cloud Browser for iOS is not terribly different from the standard iOS Safari experience in terms of speed, but the iOS version of Maxthon has an absolutely maddening bug that sporadically turns the screen brightness on my iPad 2 down to minimum, obliging a trip to the iOS Settings to restore it. I suspect that Maxthon for iOS’s Brightness Control feature that purportedly lets you adjust screen brightness from within the browser, and/or Night Mode that adjusts screen brightness in low light situations are responsible for this behavior. -
