Abstract

(from the Introduction)

This paper studies the importance of consumer-related information to the market for display advertising and, in turn, to the publishers who produce and distribute online content. Our study is based on two primary data sets. The first is a large, impression-level database of advertising placements during a one-week period in August 2013, provided by two anonymous companies that operate advertising exchanges with automated bidding. These data form the basis for an econometric analysis that allows us to measure the premium paid by advertisers for ads served to customers with cookies, and ultimately to assess the added economic value generated by information sharing in the online content market. The second data set, provided by Adomic, measures the relative prevalence of ads generated by different advertising models based on observations of display ad placements for the top 4000 publishers. This data set allows us to assess the relative significance of third party advertising technology models to the industry in general, and to smaller, “long-tail” web sites in particular.

The results of our econometric analysis corroborate and extend an emerging body of empirical work documenting the value of information sharing in online advertising. Our estimates indicate that advertisers place significantly greater value on users for whom more information is available, and our results are highly significant both in a statistical and economic sense: after controlling for other factors, the availability of cookies to capture user-specific information is found to increase the observed exchange transaction price by at least 60 percent relative to the average price (for users with “new” cookies), and by as much as 200 percent (for users with longer-lived cookies). In addition, the Adomic data reveal that even the largest publishers rely on third-party technology models to serve approximately half of their advertising impressions, while “long-tail” publishers rely upon third-party technology models for up to two thirds of their advertising volumes.

Fast Unfolding of Communities of Large Networks | Blondel, Guillaume, Lambiotte, Lefebre

Vincent D. Blondel, Jean-Loup Guillaume, Renaud Lambiotte, Etienne Lefebvre; Fast unfolding of communities in large networks; In Journal of Statistical Mechanics: Theory and Experiment; Volume 10; 2008; 12 pages; landing

Abstract

We propose a simple method to extract the community structure of large networks. Our method is a heuristic method that is based on modularity optimization. It is shown to outperform all other known community detection method in terms of computation time. Moreover, the quality of the communities detected is very good, as measured by the so-called modularity. This is shown first by identifying language communities in a Belgian mobile phone network of 2.6 million customers and by analyzing a web graph of 118 million nodes and more than one billion links. The accuracy of our algorithm is also verified on ad-hoc modular networks.

Investigating User Privacy in Android Ad Libraries | Stevens, Gibler, Crussell, Erickson, Chen

Ryan Stevens, Clint Gibler, Jon Crussell, Jeremy Erickson, Hao Chen; Investigating User Privacy in Android Ad Libraries; In Proceedings of MOST (MOST); 2012; 10 pages.

Abstract

Recent years have witnessed incredible growth in the popularity and prevalence of smart phones. A flourishing mobile application market has evolved to provide users with additional functionality such as interacting with social networks, games, and more. Mobile applications may have a direct purchasing cost or be free but ad-supported. Unlike in-browser ads, the privacy implications of ads in Android applications has not been thoroughly explored. We start by comparing the similarities and differences of in-browser ads and in-app ads. We examine the effect on user privacy of thirteen popular Android ad providers by reviewing their use of permissions. Worryingly, several ad libraries checked for permissions beyond the required and optional ones listed in their documentation, including dangerous permissions like CAMERA , WRITE CALENDAR and WRITE CONTACTS . Further, we discover the insecure use of Android’s JavaScript extension mechanism in several ad libraries. We identify fields in ad requests for private user information and confirm their presence in network data obtained from a tier-1 network provider. We also show that users can be tracked by a network sniffer across ad providers and by an ad provider across applications. Finally, we discuss several possible solutions to the privacy issues identified above.

DECAF: Detecting and Characterizing Ad Fraud in Mobile Apps | Liu, Nath, Govindan, Liu

Bin Liu, Suman Nath, Ramesh Govindan, Jie Liu; DECAF: Detecting and Characterizing Ad Fraud in Mobile Apps; In Proceedings of NSDI (NSDI); 2014; 15 pages.

Abstract

Ad networks for mobile apps require inspection of the visual layout of their ads to detect certain types of placement frauds. Doing this manually is error prone, and does not scale to the sizes of today’s app stores. In this paper, we design a system called DECAF to automatically discover various placement frauds scalably and effectively. DECAF uses automated app navigation, together with optimizations to scan through a large number of visual elements within a limited time. It also includes a framework for efficiently detecting whether ads within an app violate an extensible set of rules that govern ad placement and display. We have implemented DECAF for Windows-based mobile platforms, and applied it to 1,150 tablet apps and 50,000 phone apps in order to characterize the prevalence of ad frauds. DECAF has been used by the ad fraud team in Microsoft and has helped find many instances of ad frauds.

AdRob: Examining the Landscape and Impact of Android Application Plagiarism | Gibler, Stevens, Crussell, Chen, Zang, Choi

Abstract

Malicious activities involving Android applications are rising rapidly. As prior work on cyber-crimes suggests, we need to understand the economic incentives of the criminals to design the most effective defenses. In this paper, we investigate application plagiarism on Android markets at a large scale. We take the first step to characterize plagiarized applications and estimate their impact on the original application developers. We first crawled 265,359 free applications from 17 Android markets around the world and ran a tool to identify similar applications (“clones”). Based on the data, we examined properties of the cloned applica tions, including their distribution across different markets, application categories, and ad libraries. Next, we examined how cloned applications affect the original developers. We captured HTTP advertising traffic generated by mobile ap plications at a tier-1 US cellular carrier for 12 days. To associate each Android application with its advertising traffic, we extracted a unique advertising identifier (called the client ID) from both the applications and the network traces. We estimate a lower bound on the advertising revenue that cloned applications siphon from the original developers, and the user base that cloned applications divert from the original applications. To the best of our knowledge, this is the first large scale study on the characteristics of cloned mobile applications and their impact on the original developers.

Narrative Clip, still not ready

Recommendation

Avoid.

Currently

  • Stated in Requirements To Use The Narrative Clip
  • <quote>Not supported yet: Linux, Blackberry, Windows phone, etc.</quote>
  • <quote>The Narrative Clip can’t be used as a regular USB memory stick because it doesn’t mount as USB mass-storage device.</quote> [and not as MTP either?]

Scheme

  • Your photos are only stored in their cloud “for easy access.”
  • You have to buy a “Narrative Cloud subscription” to access them.
  • Technical Specifications

Reasonable & Prudent Thinking

  • Photos are timestamped and (GPS) geotagged.
  • No guarantee of continued access after the company folds.
  • Seems ripe for builtin backdoors [for improper elements].
  • They’ll build a map of your facilities based on your photos.

And … although Privacy Policies are silly because they are just that “policies” and they can change at any time for any reason, and for no reason … they don’t even seem to have hired up someone to write them a boilerplate.

When would it be ready?

  • Upload to my own gear, that I own, gear that is stored in my own house.
  • No ongoing operating fees.
  • No “cloud” access.
  • Standard USB access to the data on the device
    • MTP
    • Mass Storage
  • i.e. Supports Linux.

Anyone considered this?
