Under algorithmic governance, biological death historically conceptualized as the absolute boundary of civic agency and political subjectivity Is increasingly converted into a permanent informational resource. This paper untangles the conceptual and practical contours of digital necropolitics, tracing how postmortem data is captured, preserved, and financialized within platform capitalism. Drawing on the theoretical interventions of Achille Mbembe, Giorgio Agamben, and Luciano Floridi, the analysis addresses the ontological mutation of the "informational body" and its subsequent vulnerability to necro-authoritarian exploitation, particularly through electoral simulations, behavioral modeling, and the artificial reanimation of ideological remains. By exposing the severe accountability gaps intrinsic to opaque algorithmic mediation, the study argues that reviving democratic vitality requires moving beyond traditional data protection frameworks. Instead, it advocates for the institutionalization of "postmortem citizenship" and a radical, political right to be forgotten a structural shift necessary to reclaim digital sovereignty and preserve an autonomous public sphere grounded in the lived choices of free, human subjects. The paper is structurally organized into the following analytical sections:1. Informational Remains as Political Capital: Examines the material and infrastructural reality of postmortem data generation.2. Platform Sovereignty and the Logic of Necro-Exploitation: Analyzes how global technology corporations exercise jurisdiction over digital remains outside traditional state frameworks.3. The Political Valorization of Ideological Remains and Simulacral Reanimation: Critiques the instrumentalization of the deceased's symbolic capital to deepen political polarization.4. The Right to Be Forgotten and Sovereign Expropriation: Evaluates the systemic alienation of identity and the reduction of the deceased to a "Digital Homo Sacer."5. The Politics of the "Black Box": Explores the erosion of democratic accountability through corporate optimization and algorithmic mediation.6. Rethinking Representation: Deconstructs the phenomenon of "phantom representation" and informational inertia using Latourian and Deleuzian frameworks.7. Necro-Authoritarianism and Electoral Simulation: Details the manifestation of digital sovereignty through the perpetuation of digital ghosts.8. Reconstructing Digital Sovereignty: Proposes legal standards for "postmortem citizenship" and "informational inviolability."9. Algorithmic Accountability and the Political Right to Be Forgotten: Outlines an framework for "informational ecology" as a condition for democratic renewal.
