The Impact of Ad-Blockers on Online Consumer Behavior
Marketing Science Institute Working Paper Series 2021 Report No. 21-119 The Impact of Ad-blockers on Online Consumer Behavior Vilma Todri “The Impact of Ad-blockers on Online Consumer Behavior” © 2021 Vilma Todri MSI Working Papers are Distributed for the benefit of MSI corporate and academic members and the general public. Reports are not to be reproduced or published in any form or by any means, electronic or mechanical, without written permission. Marketing Science Institute Working Paper Series The Impact of Ad-blockers on Online Consumer Behavior Vilma Todri Goizueta Business School, Emory University, Atlanta, GA 30322 [email protected] Digital advertising is on track to become the dominant form of advertising but ad-blocking technologies have recently emerged posing a potential threat to the online advertising ecosystem. A significant and increasing fraction of Internet users has indeed already started employing ad-blockers. However, surprisingly little is known yet about the effects of ad-blockers on consumers. This paper investigates the impact of ad- blockers on online search and purchasing behaviors by empirically analyzing a consumer-level panel dataset. Interestingly, the analyses reveal that ad-blockers have a significant effect on online purchasing behavior: online consumer spending decreases due to ad-blockers by approximately $14:2 billion a year in total. In examining the underlying mechanism of the ad-blocker effects, I find that ad-blockers significantly decrease spending for brands consumers have not experienced before, partially shifting spending towards brands they have experienced in the past. I also find that ad-blockers spur additional unintended consequences as they reduce consumers' search activities across information channels. -

Optical character recognition CAPTCHA. (OCR) method has been used in extracting the text from images. OCR has various applications which include extracting text from any document or image or involves just for reading and processing the text available in digital form. The accuracy of OCR can be dependent on text segmentation and pre-processing algorithms. Sometimes it is difficult to retrieve text from the image because of different size, style, orientation, a complex background of image etc. From vehicle number plate the authors tried to extract vehicle number by using various OCR tools like Tesseract, GOCR, Ocrad and Tensor flow. The authors in this research paper have tried to diagnose the best possible method for optical character recognition and have provided with a comparative analysis of their accuracy.

Will Ad Blocking Break the Internet? Ben Shiller, Joel Waldfogel, and Johnny Ryan NBER Working Paper No. 23058 January 2017 JEL No. L81,L82 ABSTRACT Ad blockers allow Internet users to obtain information without generating ad revenue for site owners; and by 2016 they were used by roughly a quarter of site visitors. Given the ad-supported nature of much of the web, ad blocking poses a threat to site revenue and, if revenue losses undermine investment, a possible threat to consumers' access to appealing content. -
Enforcing Abstract Immutability
Enforcing Abstract Immutability by Jonathan Eyolfson A thesis presented to the University of Waterloo in fulfillment of the thesis requirement for the degree of Doctor of Philosophy in Electrical and Computer Engineering Waterloo, Ontario, Canada, 2018 © Jonathan Eyolfson 2018 Examining Committee Membership The following served on the Examining Committee for this thesis. The decision of the Examining Committee is by majority vote. External Examiner Ana Milanova Associate Professor Rensselaer Polytechnic Institute Supervisor Patrick Lam Associate Professor University of Waterloo Internal Member Lin Tan Associate Professor University of Waterloo Internal Member Werner Dietl Assistant Professor University of Waterloo Internal-external Member Gregor Richards Assistant Professor University of Waterloo ii I hereby declare that I am the sole author of this thesis. This is a true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. iii Abstract Researchers have recently proposed a number of systems for expressing, verifying, and inferring immutability declarations. These systems are often rigid, and do not support “abstract immutability”. An abstractly immutable object is an object o which is immutable from the point of view of any external methods. The C++ programming language is not rigid—it allows developers to express intent by adding immutability declarations to methods. Abstract immutability allows for performance improvements such as caching, even in the presence of writes to object fields. This dissertation presents a system to enforce abstract immutability. First, we explore abstract immutability in real-world systems. We found that developers often incorrectly use abstract immutability, perhaps because no programming language helps developers correctly implement abstract immutability. -

What Are Kernel-Mode Rootkits?
www.it-ebooks.info Hacking Exposed™ Malware & Rootkits Reviews “Accessible but not dumbed-down, this latest addition to the Hacking Exposed series is a stellar example of why this series remains one of the best-selling security franchises out there. System administrators and Average Joe computer users alike need to come to grips with the sophistication and stealth of modern malware, and this book calmly and clearly explains the threat.” —Brian Krebs, Reporter for The Washington Post and author of the Security Fix Blog “A harrowing guide to where the bad guys hide, and how you can find them.” —Dan Kaminsky, Director of Penetration Testing, IOActive, Inc. “The authors tackle malware, a deep and diverse issue in computer security, with common terms and relevant examples. Malware is a cold deadly tool in hacking; the authors address it openly, showing its capabilities with direct technical insight. The result is a good read that moves quickly, filling in the gaps even for the knowledgeable reader.” —Christopher Jordan, VP, Threat Intelligence, McAfee; Principal Investigator to DHS Botnet Research “Remember the end-of-semester review sessions where the instructor would go over everything from the whole term in just enough detail so you would understand all the key points, but also leave you with enough references to dig deeper where you wanted? Hacking Exposed Malware & Rootkits resembles this! A top-notch reference for novices and security professionals alike, this book provides just enough detail to explain the topics being presented, but not too much to dissuade those new to security.” —LTC Ron Dodge, U.S.
