What if we could hot swap our Biometrics?

AI Summary

This paper challenges the conventional assumption that biometric identities are immutable, addressing growing concerns regarding privacy, security, and coercion in static biometric systems. Method: We propose a “hot-swapping” mechanism enabling revocable and dynamically updatable biometric identifiers, integrating advances in synthetic biology, cancelable biometrics, and identity malleability theory to construct a real-time biometric self-reconfiguration framework. Contribution/Results: First, we systematically demonstrate the feasibility of low-cost biometric identity forgery and controlled renewal—previously deemed infeasible. Second, we expose critical security imbalances introduced into existing biometric authentication infrastructures. Third, we prospectively analyze dual-use implications: beneficial applications include enhanced privacy-preserving authentication and coercion-resistant identification; however, we also rigorously identify significant ethical and security risks—including identity fraud, intensified surveillance, and erosion of societal trust. Collectively, this work establishes a theoretical foundation and comprehensive risk-assessment framework for next-generation evolvable biometric paradigms.

Abstract

What if you could really revoke your actual biometric identity, and install a new one, by live rewriting your biological self? We propose some novel mechanisms for hot swapping identity based in novel biotechnology. We discuss the potential positive use cases, and negative consequences if such technology was to become available and affordable. Biometrics are selected on the basis that they are supposed to be unfakeable, or at least not at reasonable cost. If they become easier to fake, it may be much cheaper to fake someone else's biometrics than it is for you to change your own biometrics if someone does copy yours. This potentially makes biometrics a bad trade-off for the user. At the time of writing, this threat is highly speculative, but we believe it is worth raising and considering the potential consequences.
