Ambient back scatter
Ambient backscatter is a new wireless communication technique that allows devices to communicate and transmit data to one another without an internal power source. It works by harvesting existing radio frequency signals in the air from sources like TV, cell towers, and WiFi and using them as both a source of power and a communication medium. Researchers at the University of Washington have created prototype devices that are able to communicate over several feet using this technique both indoors and outdoors without batteries by reflecting ambient signals between each other. This new approach could enable many new applications for low-power devices that do not require batteries or external power sources.

Touchless Touchscreen
A touchless touchscreen uses optical pattern recognition and a solid state optical matrix sensor to detect hand movements in front of the screen instead of requiring physical contact. The sensor is made up of a matrix of pixels, each with photodiodes that convert incoming light to electric charge. The sensor generates signals that are processed by a digital image processor to provide output and interpret gestures without the user touching the display. Touchless touchscreens offer advantages like not wearing down the screen surface and allowing control from a distance, though sightline remains a limitation currently. The technology continues developing with potential for full body control of devices in the future.
An atm with an eye
This document proposes an ATM system that uses facial recognition instead of cards and PINs for verification.

The Future of Authentication for IoT
The rapid expansion of the Internet of Things has fostered convenience and connectedness for consumers. It has also opened the door for creative hackers. Recently, hackers used hundreds of thousands of common internet-connected devices in consumers’ homes, without the owners’ knowledge, to launch a DDoS attack that temporarily brought down crucial parts of the internet’s infrastructure.
Attacks in the past have shown that passwords in IoT devices provide insufficient security. Additionally, IoT devices are too constrained for implementing biometric functions.
The question then becomes how to authenticate to such devices and can the industry adopt a standardized approach despite a highly fragmented IoT landscape. This presentation by Rolf Lindemann of Nok Nok Labs, explores how FIDO Authentication can provide convenient and strong authentication in an array of IoT use cases.

Sandbox
Sandboxing creates confined execution environments for running untrusted programs. It works by restricting programs' access to system files and resources to minimize risks if the program misbehaves. Examples include sandboxing web pages in browsers, PDFs in Adobe Reader, and mobile apps. Sandboxes can detect unknown viruses with low false alarms and allow testing malware safely. Virtual machines and tools like Sandboxie provide sandboxing for any program. Without sandboxing, hostile programs would have unlimited access to users' computers.
Presentation On "Wi-Max Technology"
WiMAX is a wireless broadband technology that provides transmission of data using a wireless signal. It supports transmission of up to 30 miles for fixed users and 5-15 km for mobile users.

In 2000 we said that the internet is at a crossroad between surveillance and freedom. Freenet started to fight for ensuring freedom of the press. Then 9/11 happened. In 2013 Edward Snowden made the general public realize that we are already far past that crossroad. He gave us precious time to turn back the wheel and take the road towards freedom.Viewers also liked (20)

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex Proofs
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

However, as technological advancements continue to push the boundaries of innovation, alternative operating systems have emerged, challenging the status quo and offering users a fresh perspective on computing.
One such alternative that has garnered significant attention and acclaim is Nitrux Linux 3.5.0, a sleek, powerful, and user-friendly Linux distribution that promises to redefine the way we interact with our devices. With its focus on performance, security, and customization, Nitrux Linux presents a compelling case for those seeking to break free from the constraints of proprietary software and embrace the freedom and flexibility of open-source computing.
Full-RAG: A modern architecture for hyper-personalization
Mike Del Balso, CEO & Co-Founder at Tecton, presents "Full RAG," a novel approach to AI recommendation systems, aiming to push beyond the limitations of traditional models through a deep integration of contextual insights and real-time data, leveraging the Retrieval-Augmented Generation architecture. This talk will outline Full RAG's potential to significantly enhance personalization, address engineering challenges such as data management and model training, and introduce data enrichment with reranking as a key solution. Attendees will gain crucial insights into the importance of hyperpersonalization in AI, the capabilities of Full RAG for advanced personalization, and strategies for managing complex data integrations for deploying cutting-edge AI solutions.
“I’m still / I’m still / Chaining from the Block”
