According to the recently leaked document from NSA by the Guardian, the U.S government is spying each and every conversation done by the American over the internet. Whether, it is via Google, Facebook or any other major brand. Furthermore, U.S government is also receiving phone records of millions of customer using Verizon.The program through which the government of U.S is doing all this stuff is known as “Prism”. One of the U.S artists “Brooklyn” these days have began to produce songs to create warning regarding all the happenings. His latest album has gotten a positive response from the people of U.S.; same thing has been done by Firefox too.Justin Blinder has introduced a new add-on to Firefox by the name of “The Dark side of the prism”. It’s quite an unusual add-on which plays a classical song “The Dark Side of the Moon” whenever a user opens a site where he could be caught by the surveillance action. According to Blinder, he created this add-in just 4 hours and the main purpose for this was to stop people from being tapped into surveillance act.In one of the interviewees to the Guardian, Blinder said:"Dark Side of the Prism" uses Pink Floyd's aural prism (Dark Side of the Moon) as a playlist to the NSA's tracking efforts, serving as an auditory reminder of how our online activities are surveilled.Whenvisiting any URLs that have been (publicly) targeted by Prism, a small notification will appear alerting that this site is being surveilled.Download :
