It's plain impossible for any other process to peek into that memory space, because it's the very fundamental principle of Virtual Memory and Security that all computer system, literally ALL, would follow. That means it must know " what" should be censored, then it must know " where" is that sensitive data on screen, then it must know " how large" is that floating bar.Īll these informations are handled by the web browser, and all these parameters are buried deep inside application memories of that web browser app, which is a virtual memory space assigned by the system kernel. Your computer needs to know how to place that floating bar. Only pages that have these sensitive data embedded inside a container (, ,, or other elements ) with a valid CSS class identifier will work. Depending on how the web pages is constructed, you may not be able to change anything at all. It's recommended to do that in Chrome since it's developer tool is more user friendly.īe warned: it's not guaranteed to work. You need to create rules / scripts for every page. Every page will have its own set of CSS and Javascript so it's now possible to have a single rule for everything. You need to be familiar with HTML5, CSS and Javascript, and you need to observe the DOM of that web page in web browser's Developer Mode, so that you know what's the elements to be modified. You can do that with browser extension like Cascadea ( ) to inject new CSS, and Tampermonkey ( ) to inject new Javascript into any web page. For example, you can change font size & color so that the text will blend into background. If the targets are web pages, it is possible to overwrite embedded CSS and / or Javascript in those web pages, so that the "sensitive data" will follow your customized display style. It is not possible for any external process to know where that "sensitive data" is located only the app that renders canvas knows it. It's not possible to do so outside of the application that displays these informations. So in order to actually watch the games, it's usually on a 12-hour delay.Īnyway is there a way to float a black bar on my screen to censor these things? Thanks. Hovering the censor bar over scores on ESPN so I can read an article without knowing who won today's games.įor the last two, in case you're wondering why, I live in Taiwan and every American sports game is playing during our morning time. Hovering the censor bar over scores of games being simultaneously broadcast while I'm watching games so that those other games don't get spoiled for me. Hovering the censor bar over personal information while making explainer videos. Hovering the censor bar over student names in Google Classroom so that I don't know whose work I'm grading, allowing me to be a little more objective. These two things, amother a few other activities, often leave me requiring/desiring a floating black censor bar in my maccbook. I'm a teacher, and also an avid fan of sports.
