Ghosts in the Machine: The New Age of Identity is a gripping exploration of how digital identity, once a simple username and password, has become the most contested frontier of modern civilization. Joseph F. Miceli Jr.—a veteran identity strategist and originator of the IAM 3.0 framework—guides readers through the collapse of the old fortress model of cybersecurity and the birth of a new era where humans and machines coexist in a shared web of trust, risk, and autonomy.
