Description

This lecture covers the CrowdNotifier protocol, a privacy-preserving presence tracing system designed to notify individuals who were in contact with SARS-CoV-2-positive attendees in crowded environments. It discusses the limitations of traditional contact tracing methods, the advantages and disadvantages of CrowdNotifier, and the need for efficient notification solutions. The protocol's ability to complement manual contact tracing, provide strong privacy protection, and scale nationally is highlighted. The lecture emphasizes the importance of addressing airborne transmission risks beyond close physical contact, especially in crowded indoor settings. It also explores the challenges faced by contact tracers in notifying individuals present at high-risk events and locations. The presentation concludes by introducing CrowdNotifier as a simple yet effective solution that leverages QR code scanning for notifying presence contacts.

Privacy law

Privacy law is the body of law that deals with the regulating, storing, and using of personally identifiable information, personal healthcare information, and financial information of individuals, which can be collected by governments, public or private organisations, or other individuals. It also applies in the commercial sector to things like trade secrets and the liability that directors, officers, and employees have when handing sensitive information.

Airborne transmission

Airborne transmission or aerosol transmission is transmission of an infectious disease through small particles suspended in the air. Infectious diseases capable of airborne transmission include many of considerable importance both in human and veterinary medicine. The relevant infectious agent may be viruses, bacteria, or fungi, and they may be spread through breathing, talking, coughing, sneezing, raising of dust, spraying of liquids, flushing toilets, or any activities which generate aerosol particles or droplets.

Information privacy

Information privacy is the relationship between the collection and dissemination of data, technology, the public expectation of privacy, contextual information norms, and the legal and political issues surrounding them. It is also known as data privacy or data protection. Data privacy is challenging since attempts to use data while protecting an individual's privacy preferences and personally identifiable information. The fields of computer security, data security, and information security all design and use software, hardware, and human resources to address this issue.

Pathogen transmission

In medicine, public health, and biology, transmission is the passing of a pathogen causing communicable disease from an infected host individual or group to a particular individual or group, regardless of whether the other individual was previously infected. The term strictly refers to the transmission of microorganisms directly from one individual to another by one or more of the following means: airborne transmission – very small dry and wet particles that stay in the air for long periods of time allowing airborne contamination even after the departure of the host.

Privacy engineering

Privacy engineering is an emerging field of engineering which aims to provide methodologies, tools, and techniques to ensure systems provide acceptable levels of privacy. In the US, an acceptable level of privacy is defined in terms of compliance to the functional and non-functional requirements set out through a privacy policy, which is a contractual artifact displaying the data controlling entities compliance to legislation such as Fair Information Practices, health record security regulation and other privacy laws.
