What is privacy? What is identity? What is anonymity? These are questions in the background of Cole Stryker’s new book, Hacking the Future: Privacy, Identity, and Anonymity on the Web. You’d think with all three in the title they’d be at the forefront, but Stryker largely leaves the philosophical questions unasked and unexamined. His concerns are in the real world — be it the physical or digital one — and his definitions of the above are thusly what you’d expect. As a so-called “digital native,” Stryker is willing to take a stab at explaining why anonymity is so worthy of protection, but his perspective also thankfully belies his belief that it is and should remain a given on the internet — even as our outward concerns about privacy erode and we grow ever more comfortable living in the age of “over-sharing.”
