User authentication in mobile and web applications is a very common and integral use case. Implementing basic authentication is an easy solution for developers but comes with several pitfalls that impair user experience like (re-)entering passwords, the need to create a new unique password or even just the input of personal data on a flaky keyboard while registering a new account. In this talk the security flaws and UX implications of passwords will be discussed and Tim will highlight which different techniques exist that are able to offer a more mobile friendly flow. Highlighting authorization and authentication techniques like OAuth, OpenID Connect and even hardware features like Bluetooth Low Energy this talk will be interesting for anyone who's facing a situation where creating and storing user accounts matters.

Cryptography is a complex and confusing subject. In this talk you will learn about the core components of cryptography used in software development: securing data with encryption, ensuring data integrity with hashes and digital signatures, and protecting passwords with key derivation functions. While learning how to use these components, you will also learn the best practices that drive strong cryptography . This talk won’t make you a cryptography expert but it will give you the knowledge necessary to use cryptography properly. No prior knowledge of cryptography is required for this presentation.

CoinMiners are on the rise, trending so high that in the last couple of month they almost completely replaced ransomware in both media and the research community. Unlike ransomware which profit from rapid encryption of user’s data taken hostage, CoinMiners profit comes from high jacking computer resources. As long as the CoinMiner stays undetected and stealth, the higher its author profit. In this talk we will focus on the unexplored territory of CoinMiner evasive maneuver and functionality to avoid getting found by its victims and provide tactics and tools to combat them.

This talk is an extended version of my session at HTML5DevConf. It was held on Friday Nov. 20th 2015 at DevFest Asia / JSConf Asia in Singapore. The arena of proper authentication and data security standards is often some of the most misunderstood, confusing, and tricky aspects of building any Node site, app, or service, and the fear of data breaches with unencrypted or poorly encrypted data doesn’t make it any better. We’re going to tackle this field, exploring the proper methodologies for building secure authentication and data security standards. We’ll run through: - Building on top of OAuth 2 and OpenID Connect - Node middleware services for authentication - Working with proper hashing and salting algorithms, and avoiding others, for private user data - Common auth and security pitfalls and solutions In the end, we’re going to see that by understanding proper data security and authentication standards, pitfalls, and reasons for choosing one solution over another, we can make intelligent decisions on creating a solid infrastructure to protect our users and data.

HackconEU: Hackathons are for Hackers

Tim Messerschmidt

While smartphone usage is increasing year over year, single apps get less and less attention. This opens up an opportunity to turn this problem into a strength: moving your app into the background by turning core services into an invisible app. The invisible app is a concept that became apparent in the last few years; businesses like Uber have moved central parts of the app interaction into the background without requiring the user to confirm central decisions over and over. Braintree, a PayPal company, is partnering with various companies that fall into the invisible app category. In this talk Tim will share his lessons learned from mentoring startups and innovative companies that tried to achieve being “invisible”, while maintaining security, profitability and most important: a great user experience. Amongst the technologies that will be covered are tokenization and leveraging user uniqueness based on smartphone usage behavior. A wide array of sensors - like GPS, Bluetooth LE, and WiFi - supports this concept and can be leveraged creatively to get closer to being “invisible”. This talk was given as keynote at the summer edition of Geek Picnic 2015 in Moscow.

The presentation of the talk "Solid Pods Vs Personal Knowledge Graphs: Similarities and Differences" that was given by the PhD researcher Eleni Ilkou, in the 2nd Solid Symposium. Abstract: Solid Pods and Personal Knowledge Graphs are pioneering constructs within the Semantic Web community, each offering unique avenues for empowering individuals in the digital realm. Solid Pods stand as decentralized bastions of data control which grant users unprecedented authority over their digital presence, ensuring ownership, privacy and portability of personal data. Personal Knowledge Graphs infuse personal data and activity with contextual relevance, facilitating the synthesis and discovery of knowledge. This presentation aims to briefly reflect on the main similarities and differences among the Solid Pods and Personal Knowledge Graphs.
