CS229 Project Report: Automated Photo Tagging in Facebook
CS229 Project Report: Automated photo tagging in Facebook Sebastian Schuon, Harry Robertson, Hao Zou schuon, harry.robertson, haozou @stanford.edu Abstract We examine the problem of automatically identifying and tagging users in photos on a social networking environment known as Facebook. The presented au- tomatic facial tagging system is split into three subsys- tems: obtaining image data from Facebook, detecting faces in the images and recognizing the faces to match faces to individuals. Firstly, image data is extracted from Facebook by interfacing with the Facebook API. Secondly, the Viola-Jones’ algorithm is used for locat- ing and detecting faces in the obtained images. Fur- thermore an attempt to filter false positives within the Figure 1: Schematic of the Facebook crawler face set is made using LLE and Isomap. Finally, facial recognition (using Fisherfaces and SVM) is performed on the resulting face set. This allows us to match faces 2 Collecting data from Facebook to people, and therefore tag users on images in Face- book.

Common Sites and Apps Used by Teens
Common Sites and Apps Used by Teens SOCIAL NETWORKING: Facebook is the top social network on the web as it is used by more than 1 billion people each month. You can access this service using an app on a mobile device or internet service for a computer. People set up a profile and accept “friend requests.” There is a timeline to post events and share “status updates.” Certain groups can be set up as private or public. Users can be referenced in someone else’s text or picture (tagged). Teens are moving away from fb because many parents and grandparents are on the site. Officially, individuals should be 13 years of age to create an account but students in elementary schools report using this social networking site. Like Facebook, Twitter is a social network centered on microblogging with a 140-character text limit. An uploaded picture or text message is called a “Tweet.” The public can “follow” friends, celebrities, causes, businesses or tv shows. You can “tweet” live during a show by using # (hashtag). Students report concerning “subtweets,” which are comments intended for someone to see without mentioning their username, usually with a derogatory tone. Ask.fm is another popular pre-teen social networking website where users can ask other users questions. Users have to create an account to leave or receive comments. Ask.Fm is different than Facebook and Twitter because users can ask questions or leave comments anonymously. However, there is the option for users to not receive comments unless a sender identifies himself. This has been a popular venue for cyber-bullying. -

The Meet Group teams with digital identity company Yoti to help create safer communities online NEW HOPE, Pa., July 24, 2019 - The Meet Group,Inc. (NASDAQ: MEET), a leading provider of interactive live streaming solutions, and Yoti, a digital identity company, today announced that The Meet Group plans to trial Yoti’s innovative age verification and age estimation technologies designed to create safer communities online. The Meet Group, with more than 15 million monthly active users, helps people to find connection and community through its social networking and dating apps. As a company committed to the protection of its users, The Meet Group devotes approximately half of its workforce to safety and moderation, and continuously reviews its safety procedures with the goal of meeting the highest standards of online safety and security. The relationship allows Yoti to enhance The Meet Group’s strong existing safety measures, letting users verify their age with Yoti’s age estimation technology Yoti Age Scan, or the free Yoti app where a date of birth is verified to a government issued photo ID. Yoti’s technology can help moderators at The Meet Group ensure that minors do not create accounts. Geoff Cook CEO at The Meet Group commented, “A key part of helping people to create meaningful connections is to keep them safe online. We have already committed ourselves to one-tap report abuse capability, clear and frequent safety education, and proactive and transparent moderation, and now with Yoti’s age verification and estimation technologies, we look forward to being one of the few app operators in social or dating who can respond to reports of underage users quickly and accurately. -
Some Mobile Apps Add Anonymity to Social Networking
Log in / Create an account Search Subscribe Topics+ The Download Magazine Events More+ Connectivity Some Mobile Apps Add Anonymity to Social Networking Social-networking apps that eschew real names are gaining ground. by Rachel Metz February 6, 2014 On social networks like Facebook, Twitter, and LinkedIn, most people do not communicate freely, for fear of the repercussions. For just over a decade, Facebook has enforced the idea of an authentic online identity tied to each user of a social network. This might be fine for sharing news of a promotion or new baby with friends, but sometimes you’d probably like to post a status update that won’t go on your permanent record. This urge might explain why millions of people, many of them under the age of 25, are flocking to a free smartphone app called Whisper, which lets you share thoughts—a few lines of text set against a background image—without adding your real name. Secret, a newer free app for the iPhone that shares posts anonymously through your existing social networks, is based on the same idea. After years spent filling social networks like Facebook and Twitter with the minutiae of our lives, we’ve left permanent, heavily curated trails of personal data in our wake—over 1.2 billion of them on Facebook alone, judging by its user count. New apps allow us to continue being social without worrying about the repercussions of sharing the most personal confessions. “Facebook is more like the global social network; it’s like our communication layer to the world,” says Anthony Rotolo, an assistant professor at Syracuse University, who studies social networks. -
Privacy Perceptions of Photo Sharing in Facebook

INTRODUCTION Online photo sharing applications are increasingly popular, offering users new and innovative ways to share photos with a variety of people. Many social networking sites are also incorporating photo sharing features, allowing users to very easily upload and post photos for their friends and families. For example, Facebook is the largest photo sharing site on the Internet with 14 million photos uploaded daily [2]. Integrating photo Figure 1.

ATLAS Operational Monitoring Data Archival and Visualization
EPJ Web of Conferences 245, 01020 (2020) https://doi.org/10.1051/epjconf/202024501020 CHEP 2019 ATLAS Operational Monitoring Data Archival and Visualiza- tion Igor Soloviev1;∗, Giuseppe Avolio2, Andrei Kazymov3, and Matei Vasile4 1University of California, Irvine, CA 92697-4575, US 2European Laboratory for Particle Physics, CERN, Geneva 23, CH-1211, Switzerland 3Joint Institute for Nuclear Research, JINR, Dubna, Russian Federation 4Horia Hulubei National Institute of Physics and Nuclear Engineering, Bucharest, Romania Abstract. The Information Service (IS) is an integral part of the Trigger and Data Acquisition (TDAQ) system of the ATLAS experiment at the Large Hadron Collider (LHC) at CERN. The IS allows online publication of opera- tional monitoring data, and it is used by all sub-systems and sub-detectors of the experiment to constantly monitor their hardware and software components including more than 25000 applications running on more than 3000 comput- ers. The Persistent Back-End for the ATLAS Information System (PBEAST) service stores all raw operational monitoring data for the lifetime of the ex- periment and provides programming and graphical interfaces to access them including Grafana dashboards and notebooks based on the CERN SWAN plat- form. During the ATLAS data taking sessions (for the full LHC Run 2 period) PBEAST acquired data at an average information update rate of 200 kHz and stored 20 TB of highly compacted and compressed data per year. This paper reports how over six years PBEAST became an essential piece of the experi- ment operations including details of the challenging requirements, the failures and successes of the various attempted implementations, the new types of mon- itoring data and the results of the time-series database technology evaluations for the improvements towards LHC Run 3. -

Social Media As a Source of Sensing to Study City Dynamics and Urban Social Behavior: Approaches, Models, and Opportunities
Social Media as a Source of Sensing to Study City Dynamics and Urban Social Behavior: Approaches, Models, and Opportunities Thiago H. Silva, Pedro Olmo S. Vaz de Melo, Jussara M. Almeida, and Antonio A.F. Loureiro Federal University of Minas Gerais Department of Computer Science Belo Horizonte, MG, Brazil {thiagohs,olmo,jussara,loureiro}@dcc.ufmg.br Abstract. In order to achieve the concept of ubiquitous computing, popularized by Mark Weiser, is necessary to sense the environment. One alternative is use traditional wireless sensor networks (WSNs). However, WSNs have their limita- tions, for instance in the sensing of large areas, such as metropolises, because it incurs in high costs to build and maintain such networks. The ubiquity of smart phones associated with the adoption of social media websites, forming what is called participatory sensing systems (PSSs), enables unprecedented opportunities to sense the environment. Particularly, the data sensed by PSSs is very interesting to study city dynamics and urban social behavior. The goal of this work is to sur- vey approaches and models applied to PSSs data aiming the study city dynamics and urban social behavior. Besides that it is also an objective of this work discuss some of the challenges and opportunities when using social media as a source of sensing. 1 Introduction At the beginning, there were mainframes, shared by a lot of people. Then came the personal computing era, when a person and a machine have a close relationship with each other. Nowadays we are witnessing the beginning of the ubiquitous computing (ubicomp) era, when technology recedes into the background of our lives [1, 2]. -
