Towards anonymous and metadata private communication at Internet scale
… sensitive information about the users and the communication between them - often without the users ever knowing about it. In response, many Internet users have turned to end-to-end encryption, like Signal and TLS, to protect the content of the communication. Unfortunately, these works do little …

Changing communication through Facebook : redefining perceptions of public and private communication
… conducted to establish its affect on our overall communication patterns. This research study focuses on the way in which Facebook is redefining perceptions of public and private communication. Using the current body of research paired with a varied theoretical backing, this research establishes …

Product cipher negotiation with on-line evaluation for private communication over computer networks
A method is proposed to offer privacy in computer communications, using symmetric product block ciphers. The security protocol involved a cipher negotiation stage, in which two communicating parties select privately a cipher from a public cipher space. The cipher negotiation process includes an …

Analysis of the Use of Internet -Based Communication Technology for Online Post -Training Coaching
… emerged. Training professionals should select communication media based on richness and message equivocality and should develop activities that promote individual and group communication. Technology professionals should design systems with a variety of technology based on the needs of users …

Status and Integrative Complexity in Decision-Making Groups: Evidence From the United States Supreme Court and a Laboratory Experiment
… the extent to which it reflects differences in private cognition, or in public communication. The effects of status on integrative complexity were identical under public and private communication conditions, so they cannot be attributed to communication strategies alone. Under public …

Models for Privacy in Ubiquitous Computing Environments
For secure and private communication, we present a model for trustworthy routing, with a policy specification language that is computationally efficient to enforce. We show how quantitative trust models can be used to find trustworthy paths of communication and explore various semantic models of …

Multi-party and distributed private messaging
In this thesis, I extend private messaging systems by designing multi-party private messaging models and contribute to the implementation of a distributed private messaging system. Private communication is of increasing interest yet current state-of-the- art adopted solutions are inadequate in …

A mathematical model to describe haemophilus influenzae type B within Western Australia
… was a distinct lack of relevant data available. Private communication with individual’s such as Dr Jeffrey Hanna and Dr Beryl Wild resulted in practical information being obtained that was used to estimate certain parameters. The deterministic mathematical models within the thesis are extensions …

A distributed metadata-private messaging system
Private communication over the Internet continues to be a difficult problem. Even if messages are encrypted, it is hard to deliver them without revealing metadata about which pairs of users are communicating. Scalable systems such as Tor are susceptible to traffic analysis. In contrast, the …

Dynamic, personalized discrete choice incentive allocation to optimize system performance
… method is useful in systems that have direct and private communication with each user but are limited by having users enter the system at different times. The method must offer a menu of choices and incentives on demand while still considering users that are yet to come. I discuss several …

Reforms to the laws on the surveillance of private communications
… of the State to invade the privacy of our communications threatens the personal space within which we live “our daily lives”. The Constitutional Court in AmaBhungane evaluated the law regulating communications surveillance – the Regulation of Interception of Communications and Provision of …

A PROOF OF CONCEPT FOR DETECTION OF PALATO-LINGUAL CONTACT WITHOUT INTRAORAL ELECTRODES IN A HUMAN PARTICIPANT
… electroglottography (UEGG, Dr. Steven Cloud, private communication, July 17, 2022).</p> <p>Two distinctive patterns of waveforms were obtained in this study that showed two visually different transitions: (1) when the tongue tip was raised from the oral floor to touch the hard palate, and (2) …

Interactive media and social exchange of market information
A persistent belief in marketing communication is that consumer word-of-mouth (WOM) plays a crucial role in the diffusion of information in a society. The Internet, the largest network ever created by humans, demonstrates the validity of this wisdom by enabling individual consumers from all over …

Private and Provably Efficient Federated Decision-Making
… constraints, such as differentially private communication, heavy-tailed perturbations, and the presence of adversarial corruptions. For each of these constraints, we present algorithms with near-optimal regret guarantees and maintain competitive experimental performance on real-world …

On the capacity of the erasure channel and the construction of an [epsilon]-randomizing map
… theory. The first half of this thesis presents a communication protocol for the erasure channel assisted by backward classical communication, which achieves a significantly better rate than the best prior result. In addition, we reduce the proof of a new upper bound for the capacity of the channel …

Establishing trust in confidential computation and communication systems
Modern confidential computation and communication systems aim to safeguard data in-use and protect metadata, extending privacy beyond the limits of conventional approaches. Trust is foundational to their security and adoption, yet difficult to establish due to strict privacy requirements, technical …

The social media revolution and political activism. A case study of Zimbabwe
… leveraged its unrestricted access to public and private communication spaces to shape voter decision-making and consolidate its political messaging. In contrast, the CCC and other progressive forces, constrained by state repression, adopted alternative strategies that heavily relied on social …
