However, current fingerprint-based biometric systems are vulnerable to spoofing attacks. Moreover, single feature-based static approach does not perform equally over different fingerprint sensors and spoofing materials. In this paper, we propose a static software approach. We propose to combine low-level gradient features from speeded-up robust features, pyramid extension of the histograms of oriented gradient and texture features from Gabor wavelet using dynamic score level integration. We extract these features from a single fingerprint image to overcome the issues faced in dynamic software approaches, which require user cooperation and longer computational time. A experimental analysis done on LivDet 2011 data produced an average equal error rate (EER) of 3.95% over four databases. The result outperforms the existing best average EER of 9.625%. We also performed experiments with LivDet 2013 database and achieved an average classification error rate of 2.27% in comparison with 12.87% obtained by the LivDet 2013 competition winner.

Alex Tapscott: "Blockchain Revolution" | Talks at Google
Talks at Google in London were delighted to welcome Alex Tapscott to talk about his book Blockchain Revolution, looking at how the technology behind Bitcoin can reshape the world of business and transform the old order of human affairs for the better. Alex can be found on Twitter at: @alextapscott Book on Google Play - with free first chapter! https://play.google.com/store/books/details/Don_Tapscott_Blockchain_Revolution?id=bwz_CwAAQBAJ About the Book: The technology likely to have the greatest impact on the future of the world economy has arrived, and it's not self-driving cars, solar energy, or artificial intelligence. It’s called the blockchain. The first generation of the digital revolution brought us the Internet of information. The second generation powered by blockchain technology is bringing us the Internet of value: a new, distributed platform that can help us reshape the world of business and transform the old order of human affairs for the better. Blockchain is the ingeniously simple, revolutionary protocol that allows transactions to be simultaneously anonymous and secure by maintaining a tamperproof public ledger of value. Though it's the technology that drives bitcoin and other digital currencies, the underlying framework has the potential to go far beyond these and record virtually everything of value to humankind, from birth and death certificates to insurance claims and even votes. Why should you care? Maybe you're a music lover who wants artists to make a living off their art. And those examples are barely the tip of the iceberg. This technology is public, encrypted, and readily available for anyone to use. It's already seeing widespread adoption in a number of areas. For example, forty-two (and counting) of the world's biggest financial institutions, including Goldman Sachs, JPMorgan Chase, and Credit Suisse, have formed a consortium to investigate the blockchain for speedier and more secure transactions. As with major paradigm shifts that preceded it, the blockchain will create winners and losers. And while opportunities abound, the risks of disruption and dislocation must not be ignored. About the Author: Alex Tapscott is the CEO and Founder of Northwest Passage Ventures, an advisory firm building industry-leading blockchain businesses. Formerly, Alex was a senior executive at Canaccord Genuity, Canada’s largest independent investment bank. At age 25, he became the firm’s youngest-ever Vice President and in 2014, he founded the firm’s blockchain practice. Over his career, Alex has worked tirelessly for his clients, raising hundreds of millions of dollars in growth capital from a global institutional investor base, and provided sound advice and counsel.

DEF CON 24 Conference   Mike   Use Their Machines Against Them   Loading Code with a Copier
We’ve all worked on ‘closed systems’ with little to no direct Internet access. And we’ve all struggled with the limitations those systems put on us in the form of available tools or software we want to use. I didn’t like struggling, so I came up with a method to load whatever I wanted on to a closed system without triggering any common security alerts. To do this I had to avoid accessing the Internet or using mag media. In the end all I needed was an office multi-function machine and Excel. It’s all any insider needs. For my presentation and demo, I’ll show you how I delivered a select group of PowerSploit tools to a clean, isolated machine. Of course, Excel has been known as vector for macro viruses for quite some time and some of the techniques—such as hex-encoding binary data and re-encoding it on a target machine—are known binary insertion vectors but I have not found any prior work on an insider using these techniques to deliver payloads to closed systems. You’ll leave my presentation knowing why Excel, umm, excels as an insider attack tool, how to leverage Excel features to load and extract arbitrary binary data from a closed network, and what to do if this really frightens you. BioL Mike has over 20 years experience in the military. He has been part of everything from systems acquisition, to tactical intelligence collection, to staff work, to leading a unit dedicated to data loss prevention. He recently retired from active military service and is now working as a systems security engineer. This is Mike’s first security conference presentation and will also be the first public release of a tool he has written. Mike has previously published twice in 2600 magazine. Mike is super proud of his OSCP certification. He’s also a CISSP.

2007-04-25 CERIAS - Passwords Decay, Words Endure: Towards Secure and Re-usable Multiple Password...
Recorded: 04/25/2007 CERIAS Security Seminar at Purdue University Passwords Decay, Words Endure: Towards Secure and Re-usable Multiple Password... Umut Topkara, Purdue University Human aspects of information security were identified at the early stages in the history of time shared computing. The recent surge in attacks that exploit security vulnerabilities involving human factors have also put them under the spotlight of various research fields including human-computer interaction, information security and cognitive science. The human centered vulnerabilities involve an interplay of a broad range of actors from Information Technology specialists (who might mis-configure the security hardware and software or enforce impractical security policies) to end users (who might have a poor understanding of good security practices or not know the possible impact of weak security).This talk will focus on human aspects of authentication mechanisms. I will present two methods that we have developed to reinforce the security of existing systems by improving their usability.Previous studies have repeatedly shown that users find it taxing to remember truly random passwords. Many users choose easy to guess --therefore not secure-- passwords, since they require the least effort to recall. Experienced users adopt "mnemonic phrases" to generate and easily recall more secure passwords. However, regularity in the human languages may render such passwords vulnerable against a brute force attack. In the first part of the talk, I will present a method that we developed to automatically generate mnemonic phrases which can yield secure passwords in an effort to increase the usability of text password authentication.Many computer users need to remember a multiplicity of usernames and passwords for different systems, and the users tend to reuse passwords across these systems which may have different security guarantees. In such cases remembering a different mnemonic phrase for each password does not scale and quickly becomes a challenging task. In the second part of the talk, I will present a scheme that helps the users remember a multiplicity of truly random passwords. The new scheme is applicable to an existing password authentication system without any modification, as it does not require any form of involvement from the service provider (e.g., bank, brokerage). Nor does it require the user to have any computing device at hand (not even a calculator). The scheme is such that changes to passwords do not necessitate a change in what the user remembers. Hence, passwords can be frequently changed without any additional burden on the memory of the user, thereby increasing the system's security. Umut Topkara is a PhD candidate at the Computer Science Department of Purdue University. His research interests lie at the confluence of Information Security, Natural Language Processing and Computer- Human Interaction, specifically their intersection in the field of Usable Security. More recently, he has also been involved in Grid Middle-ware Engineering research. His thesis advisor is Professor Mikhail J. Atallah. He got his B.Sc. and M.Sc. degrees from Computer Engineering Department of Bilkent University. He started his graduate studies at Purdue University in 2002.

Written language only began at around 3200 BC, but spoken language has existed long ago. Learning by listening is a great way to: - increases imagination and understanding - improves your listening skills - improves your own spoken accent - learn while on the move - reduce eye strain Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article).

All generations of the iPhone use Apple's iOS mobile operating system software. The first-generation iPhone was released on June 29, 2007, and multiple new hardware iterations with new iOS releases have been released since. The user interface is built around the device's multi-touch screen, including a virtual keyboard. The iPhone has Wi-Fi and can connect to cellular networks. An iPhone can shoot video (though this was not a standard feature until the iPhone 3GS), take photos, play music, send and receive email, browse the web, send and receive text messages, follow GPS navigation, record notes, perform mathematical calculations, and receive visual voicemail. Other functionality, such as video games, reference works, and social networking, can be enabled by downloading mobile apps. As of January 2017, Apple's App Store contained more than 2.2 million applications available for the iPhone.

The original first-generation iPhone was a GSM phone and established design precedents, such as a button placement that has persisted throughout all releases and a screen size maintained for the next four iterations. The iPhone 3G added 3G network support, and was followed by the 3GS with improved hardware, the 4 with a metal chassis, higher display resolution and front-facing camera, and the 4S with improved hardware and the voice assistant Siri. The iPhone 5 featured a taller, 4-inch display and Apple's newly introduced Lightning connector. In 2013, Apple released the 5S with improved hardware and a fingerprint reader, and the lower-cost 5C, a version of the 5 with colored plastic casings instead of metal. They were followed by the larger iPhone 6, with models featuring 4.7-and-5.5-inch (120 and 140 mm) displays. The iPhone 6S was introduced the following year, which featured hardware upgrades and support for pressure-sensitive touch inputs, as well as the SE—which featured hardware from the 6S but the smaller form factor of the 5S. In 2016, Apple unveiled the iPhone 7 and 7 Plus, which add water resistance, improved system and graphics performance, a new rear dual-camera setup on the Plus model ...
