A new app would say if you’ve crossed paths with someone who is infected

Called , the free and open-source app was developed by people at MIT and Harvard, as well as software engineers at companies such as Facebook and Uber, who worked on it in their free time.&nbsp;&nbsp; Privacy concerns: The World Health Organization has called for aggressive measures to contain the spread of the coronavirus. These require not only identifying and isolating infected individuals but also identifying people they have been in contact with and where they have been, so that those people can be tested and the locations disinfected. In some countries, such as China, this data has been pulled from people’s phones and processed by the government. But this kind of government surveillance would be a hard sell in more democratic countries like the US or UK. People with Covid-19 have also faced social stigma, which is another reason to keep identifying information private. How it works: Private Kit: Safe Paths gets around by sharing encrypted location data between phones in the network in such a way that it does not go through a central authority. This lets users see if they may have come in contact with someone carrying the coronavirus—if that person has shared that information—without knowing who it might be. A person using the app who tests positive can also choose to share location data with health officials, who can then make it public.&nbsp; Raskar thinks that a fine-grained tracking approach, which would allow specific locations to be closed off and disinfected, is better than blanket shutdowns, which are socially and economically disruptive.&nbsp; Will it make a difference? Only if enough people use it, which is why Raskar and the MIT team want to get the word out. Pinpointing coronavirus hot spots seems to have , where testing stations are set up outside buildings that people with the virus have visited. But incomplete information could also lead to a false sense of security, if the app leads users to believe that certain places are safe when they aren’t. The app will only alert you to where the virus has been, not where it’s going.&nbsp; Wallpaper Engine has become a haven for ingenious Chinese users who use it to smuggle adult content as desktop wallpaper. But how long can it last?On key metrics, a VR experience elicited a response indistinguishable from subjects who took medium doses of LSD or magic mushrooms.Companies already have the systems in place that are needed to evaluate their deeper impacts on the social fabric.LinkedIn users are being scammed of millions of dollars by fake connections posing as graduates of prestigious universities and employees at top tech companies.Discover special offers, top stories,upcoming events, and more.
