Are websites and social media apps blocked? Is your network unusually slow? Run OONI Probe to find out! With this app, you will examine the blocking of websites and instant messaging apps, measure your network's speed and performance, and check whether systems that could be responsible for censorship and surveillance are in your network. OONI Probe is developed by the Open Observatory of Network Interference (OONI), a free software project (under The Tor Project) that aims to uncover internet censorship around the world. Since 2012, OONI’s global community has collected millions of network measurements from more than 200 countries, shedding light on multiple cases of network interference. ▶ Collect evidence of internet censorship You can check whether and how websites and instant messaging apps are blocked. The network measurement data you will collect may serve as evidence of internet censorship. ▶ Detect systems responsible for censorship and surveillance OONI Probe tests are also designed to uncover the presence of systems (middleboxes) that could be responsible for censorship and surveillance. ▶ Measure the speed and performance of your network You can measure the speed and performance of your network by running OONI's implementation of the Network Diagnostic Test (NDT). You can also measure video streaming performance with the Dynamic Adaptive Streaming over HTTP (DASH) test. ▶ Open data OONI publishes network measurement data because open data allows third parties to verify OONI findings, conduct independent studies, and answer other research questions. Openly publishing OONI data also helps increase transparency of internet censorship around the world. You can explore and download OONI data here: https://ooni.io/data/ ▶ Free software All OONI Probe tests (including our NDT and DASH implementations), are based on free and open source software. You can find OONI software projects on GitHub: https://github.com/ooni. Curious to learn how OONI Probe tests work?

BEAC NG2020
Read full descriptionHide full description
This application helps the general public authenticate BEAC banknotes from the 2020 series. With a banknote from the 2020 series, users can authenticate it by comparing the security features on the banknote with those illustrated in the application. Users can authenticate the banknote by looking at the following security features with the naked eye, as illustrated in the application: watermark, incomplete pattern, banknote number, security thread. Users can authenticate the banknote by feeling the raised print on the sign for the visually impaired, the denomination, the CEMAC logo, the BEAC headquarters building, the face value of the banknote in letters and the inscription ‘Banque des Etats de l'Afrique Centrale’ (Bank of Central African States), as illustrated in the app. Users can authenticate the banknote by tilting it, as shown in the app, to observe the dynamic 3D pattern that gradually changes colour as the banknote is tilted and the security thread with a dynamic effect. Users can authenticate the banknote by placing it under a UV lamp to see, as illustrated in the app, the CEMAC map that appears in place of the watermark, the two-colour fibres and the fluorescent outlines of the scene.
