Users of the main smartphone operating systems (iOS, Android) differ only little in personality | Götz, Stieger, Reips

Friedrich M. Götz,, Stefan Stieger, Ulf-Dietrich Reips; Users of the main smartphone operating systems (iOS, Android) differ only little in personality; In Public Library of Science | One (PLOS | One); 2017-05-03; DOI:10.1371/journal.pone.0176921

Abstract

The increasingly widespread use of mobile phone applications (apps) as research tools and cost-effective means of vast data collection raises new methodological challenges. In recent years, it has become a common practice for scientists to design apps that run only on a single operating system, thereby excluding large numbers of users who use a different operating system. However, empirical evidence investigating any selection biases that might result thereof is scarce. Henceforth, we conducted two studies drawing from a large multi-national (Study 1; N = 1,081) and a German-speaking sample (Study 2; N = 2,438). As such Study 1 compared iOS and Android users across an array of key personality traits (i.e., well-being, self-esteem, willingness to take risks, optimism, pessimism, Dark Triad, and the Big Five). Focusing on Big Five personality traits in a broader scope, in addition to smartphone users, Study 2 also examined users of the main computer operating systems (i.e., Mac OS, Windows). In both studies, very few significant differences were found, all of which were of small or even tiny effect size mostly disappearing after sociodemographics had been controlled for. Taken together, minor differences in personality seem to exist, but they are of small to negligible effect size (ranging from OR = 0.919 to 1.344 (Study 1), ηp2 = .005 to .036 (Study 2), respectively) and may reflect differences in sociodemographic composition, rather than operating system of smartphone users.

Who Knows What About Me? A Survey of Behind the Scenes Personal Data Sharing to Third Parties by Mobile Apps | Zang, Dummit, Graves, Lisker, Sweeney

Jinyan Zang, Krysta Dummit, James Graves, Paul Lisker, Latanya Sweeney; Who Knows What About Me? A Survey of Behind the Scenes Personal Data Sharing to Third Parties by Mobile Apps; In Technology Science; 2015-10-30.

tl;dr → QA was performed; observations were noted: data was sent, data was received; not shown: (absence of) consent, harm.

Abstract

What types of user data are mobile apps sending to third parties? We chose 110 of the most popular free mobile apps as of June-July 2014 from the Google Play Store and Apple App Store, across 9 categories likely to handle potentially sensitive data about users including job information, medical data, and location. For each app, we used a man-in-the-middle proxy to record HTTP and HTTPS traffic that occurred while using the app and looked for transmissions that include personally identifiable information (PII), behavior data such as search terms, and location data, including geo-coordinates. An app that collects these data types may not need to notify the user in current permissions systems.

Gyrophone: Recognizing Speech From Gyroscope Signals | Michalevsky, Nakibly, Boneh

Yan Michalevsky, Gabi Nakibly, Dan Boneh; Gyrophone: Recognizing Speech From Gyroscope Signals; In Proceedings of the 23rd USENIX Security Symposium (USENIX Security 14); 2014-08-20; landing, landing

Abstract

We show that the MEMS gyroscopes found on modern smart phones are sufficiently sensitive to measure acoustic signals in the vicinity of the phone. The resulting signals contain only very low-frequency information (< 200 Hz). Nevertheless we show, using signal processing and machine learning, that this information is sufficient to identify speaker information and even parse speech. Since iOS and Android require no special permissions to access the gyro, our results show that apps and active web content that cannot access the microphone can nevertheless eavesdrop on speech in the vicinity of the phone.

Facebook turns user tracking ‘bug’ into data mining ‘feature’ for advertisers | ZDNet

Facebook turns user tracking ‘bug’ into data mining ‘feature’ for advertisers; In ZDNet; 2014-06-17.
Summary: Facebook announced changes to its privacy and advertising policies on its company blog, extending Facebook’s ability to track users outside of Facebook. This counters 2011′s position that [we] “do not track users across the web.”
