With increase in usage of the Internet, there has been an exponential increase in the use of online social media on the Internet. Websites like Facebook, Google+, YouTube, Orkut, Twitter and Flickr have changed the way Internet is being used. There is a dire need to investigate, study and characterize privacy and security on online social media from various perspectives (computational, cultural, psychological). Real world scalable systems need to be built to detect and defend security and privacy issues on online social media. This talk will give you a preview of what we do at PreCog in the area of PSOSM. I will describe briefly some of the cool ongoing projects that we have: ChaMAILeon, PhishAri, Twit-Digest, U2P2, and OCEAN. Much of our research work is made available for public use through tools or online services. Our work derives techniques from Data Mining, Text Mining, Statistics, Network Science, Public Policy, Complex networks, Human Computer Interaction, and Psychology.

In this talk, I will focus on the following: (1) Twit-Digest is a tool to extract intelligence from Twitter which can be useful to security analysts. Pro-cursor to this work is published at PSOSM 2012, this work also obtained second best award at IBM ICARE 2012. (2) OCEAN: Open source Collation of eGovernment data and Networks. Here, we show how publicly available information on Government services can be used to profile citizens in India. This work obtained the Best Poster Award at Security and Privacy Symposium at IIT Kanpur, 2013. (3) Privacy in India: Attitudes and Awareness V 2.0 U2P2, this is one of the largest ever done privacy study in India. This has been in media recently; if you are interested search for #privacyindia12 on Twitter. This work obtained the third Best Poster Award at Security and Privacy Symposium at IIT Kanpur, 2013.

Another weekend, and yet another freebie. Today, we are happy to feature a useful icon set, the Simple Icons by Dan Leech. Dan’s set contains 100 PNG icons for popular websites, apps and organisations, all in eleven sizes (16, 24, 32, 48, 64, 128, 256, 512, 1024, 2048 and 4096 pixels squared).

The white icons have transparent backgrounds, which makes them ridiculously simple to style with CSS. As a bonus, simpleicons.org maintains a list of official background colour values that can be used in conjunction with the icons, thoroughly researched and derived from official branding guidelines of each brand.

Behind the design

Here are some insights from the designer himself:

“Even though the future of Web iconography will clearly be dominated by resolution-independent formats like SVG and icon fonts, there will still be many uses for a set of simple, flexible, high-quality raster icons. That’s what I set out to achieve with Simple Icons. The set is still very much a work in progress. I plan to refine and grow the set as time goes on.”

Thanks for your fantastic work and your contribution, Dan!
