Green Pass
The EU Digital COVID Certificate (EUDCC), known in Italy as the Green Pass, and in France as the Sanitary Pass or Health Pass (''passe sanitaire''), was a COVID-19 vaccine passport created by the European Union (EU), that is valid in all member states. The EUDCC can be used when travelling within the Schengen Area. It launched in July 2021, and is/was applicable for citizens of the EU, and also for travellers from outside of the region. In October 2021, Johannes Bahrke, the European Commission's digital spokesman, said the EUDCC "set a global standard by being the only system currently in operation internationally". Since the July 2021 launch more than 591 million certificates had been issued, 438 million of them on the basis of vaccination. In the spring of 2022, the majority of member states removed the requirement to show Covid-related documents, including the cert, for people travelling from another part of the EU or Schengen Area. Several of the remaining countries ende ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

COVID-19 Test
COVID-19 testing involves analyzing samples to assess the current or past presence of SARS-CoV-2. The two main types of tests detect either the presence of the virus or antibodies produced in response to infection. Molecular tests for viral presence through its molecular components are used to diagnose individual cases and to allow public health authorities to trace and contain outbreaks. Antibody tests (serology immunoassays) instead show whether someone once had the disease. They are less useful for diagnosing current infections because antibodies may not develop for weeks after infection. It is used to assess disease prevalence, which aids the estimation of the infection fatality rate. Individual jurisdictions have adopted varied testing protocols, including whom to test, how often to test, analysis protocols, sample collection and the uses of test results. This variation has likely significantly impacted reported statistics, including case and test numbers, case fatality r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vaccine Passports During The COVID-19 Pandemic
A vaccine passport or proof of vaccination is an immunity passport employed as a credential in countries and jurisdictions as part of efforts to control the COVID-19 pandemic via vaccination. A vaccine passport is typically issued by a government or health authority, and usually consists of a digital or printed record. Some credentials may include a scannable QR code, which can also be provisioned via mobile app. It may or may not use a COVID-19 vaccine card as a basis of authentication. The use of vaccine passports is based on the general presumption that a vaccinated individual would be less likely to transmit SARS-CoV-2 to others, and less likely to experience a severe outcome (hospitalization or death) if they were to be infected, thus making it relatively safer for them to congregate. A vaccine passport is typically coordinated with policies enforced by individual businesses, or enforceable public health orders, that require patrons to present proof of vaccination for CO ...

Zlib
zlib ( or "zeta-lib", ) is a software library used for data compression. zlib was written by Jean-loup Gailly and Mark Adler and is an abstraction of the DEFLATE compression algorithm used in their gzip file compression program. zlib is also a crucial component of many software platforms, including Linux, macOS, and iOS. It has also been used in gaming consoles such as the PlayStation 4, PlayStation 3, Wii U, Wii, Xbox One and Xbox 360. The first public version of zlib, 0.9, was released on 1 May 1995 and was originally intended for use with the libpng image library. It is free software, distributed under the zlib License. Capabilities Encapsulation zlib compressed data are typically written with a gzip or a zlib wrapper. The wrapper encapsulates the raw DEFLATE data by adding a header and trailer. This provides stream identification and error detection that are not provided by the raw DEFLATE data. The gzip header, used in the ubiquitous gzip file format, is larger than ...

CBOR
Concise Binary Object Representation (CBOR) is a binary data serialization format loosely based on JSON authored by C. Bormann. Like JSON it allows the transmission of data objects that contain name–value pairs, but in a more concise manner. This increases processing and transfer speeds at the cost of human readability. It is defined in IETF . Amongst other uses, it is the recommended data serialization layer for the CoAP Internet of Things protocol suite and the data format on which COSE messages are based. It is also used in the Client-to-Authenticator Protocol (CTAP) within the scope of the FIDO2 project. CBOR was inspired by MessagePack, which was developed and promoted by Sadayuki Furuhashi. CBOR extended MessagePack, particularly by allowing to distinguish text strings from byte strings, which was implemented in 2013 in MessagePack. Specification of the CBOR encoding CBOR encoded data is seen as a stream of data items. Each data item consists of a header byte con ...

JSON
JSON (JavaScript Object Notation, pronounced ; also ) is an open standard file format and data interchange format that uses human-readable text to store and transmit data objects consisting of attribute–value pairs and arrays (or other serializable values). It is a common data format with diverse uses in electronic data interchange, including that of web applications with servers. JSON is a language-independent data format. It was derived from JavaScript, but many modern programming languages include code to generate and parse JSON-format data. JSON filenames use the extension .json. Any valid JSON file is a valid JavaScript (.js) file, even though it makes no changes to a web page on its own. Douglas Crockford originally specified the JSON format in the early 2000s. He and Chip Morningstar sent the first JSON message in April 2001. Naming and pronunciation The 2017 international standard (ECMA-404 and ISO/IEC 21778:2017) specifies "Pronounced , as in 'Jason and The ...

Corona-Warn-App
Corona-Warn-App is the official and open-source COVID-19 contact tracing app used for digital contact tracing in Germany made by SAP and Deutsche Telekom subsidiary T-Systems. It had been downloaded 22.8 million times as of 19 November 2020 and 26.2 million times as of 18 March 2021. The app has been promoted by billboard and broadcast advertisements, e.g. in cooperation with the German Football Association (DFB) and other prominent companies. The German government has announced that the app would no longer exchange tracing information as of April 30, 2023 & would enter hibernation as of June 1, 2023. Effectiveness Experts believe that time saved by using the app can be critical for improving the effectiveness contact tracing efforts. Some virologists say when at least 60% of people in Germany use it, it would be very effective. Functioning The app works with the Exposure Notification Framework (what is implemented in Google Play Services for Android and in iOS) b ...

Mobile App
A mobile application or app is a computer program or software application designed to run on a mobile device such as a phone, tablet, or watch. Mobile applications often stand in contrast to desktop applications which are designed to run on desktop computers, and web applications which run in mobile web browsers rather than directly on the mobile device. Apps were originally intended for productivity assistance such as email, calendar, and contact databases, but the public demand for apps caused rapid expansion into other areas such as mobile games, factory automation, GPS and location-based services, order-tracking, and ticket purchases, so that there are now millions of apps available. Many apps require Internet access. Apps are generally downloaded from app stores, which are a type of digital distribution platforms. The term "app", short for " application", has since become very popular; in 2010, it was listed as "Word of the Year" by the American Dialect Society. Apps a ...

QR Code
A QR code (an initialism for quick response code) is a type of matrix barcode (or two-dimensional barcode) invented in 1994 by the Japanese company Denso Wave. A barcode is a machine-readable optical label that can contain information about the item to which it is attached. In practice, QR codes often contain data for a locator, identifier, or tracker that points to a website or application. QR codes use four standardized encoding modes (numeric, alphanumeric, byte/binary, and kanji) to store data efficiently; extensions may also be used. The quick response system became popular outside the automotive industry due to its fast readability and greater storage capacity compared to standard UPC barcodes. Applications include product tracking, item identification, time tracking, document management, and general marketing. A QR code consists of black squares arranged in a square grid on a white background, including some fiducial markers, which can be read by an imaging device suc ...

Digital Signature
A digital signature is a mathematical scheme for verifying the authenticity of digital messages or documents. A valid digital signature, where the prerequisites are satisfied, gives a recipient very high confidence that the message was created by a known sender (authenticity), and that the message was not altered in transit (integrity). Digital signatures are a standard element of most cryptographic protocol suites, and are commonly used for software distribution, financial transactions, contract management software, and in other cases where it is important to detect forgery or tampering. Digital signatures are often used to implement electronic signatures, which includes any electronic data that carries the intent of a signature, but not all electronic signatures use digital signatures.

COVID-19
Coronavirus disease 2019 (COVID-19) is a contagious disease caused by a virus, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The first known case was COVID-19 pandemic in Hubei, identified in Wuhan, China, in December 2019. The disease quickly spread worldwide, resulting in the COVID-19 pandemic. The symptoms of COVID‑19 are variable but often include fever, cough, headache, fatigue, breathing difficulties, Anosmia, loss of smell, and Ageusia, loss of taste. Symptoms may begin one to fourteen days incubation period, after exposure to the virus. At least a third of people who are infected Asymptomatic, do not develop noticeable symptoms. Of those who develop symptoms noticeable enough to be classified as patients, most (81%) develop mild to moderate symptoms (up to mild pneumonia), while 14% develop severe symptoms (dyspnea, Hypoxia (medical), hypoxia, or more than 50% lung involvement on imaging), and 5% develop critical symptoms (respiratory failure ...

COVID-19 Vaccination
A COVID19 vaccine is a vaccine intended to provide acquired immunity against severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2), the virus that causes coronavirus disease 2019 ( COVID19). Prior to the COVID19 pandemic, an established body of knowledge existed about the structure and function of coronaviruses causing diseases like severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS). This knowledge accelerated the development of various vaccine platforms during early 2020. The initial focus of SARS-CoV-2 vaccines was on preventing symptomatic, often severe illness. In January 2020, the SARS-CoV-2 genetic sequence data was shared through GISAID, and by March 2020, the global pharmaceutical industry announced a major commitment to address COVID19. In 2020, the first COVID19 vaccines were developed and made available to the public through emergency authorizations and conditional approvals. Initially, most COVID19 vaccines were two-d ...
