Summary

Quantum computing threatens widely used RSA and ECC cryptography because algorithms such as Shor’s could break their underlying mathematical protections, making post-quantum cryptography and cryptographic agility increasingly important for identity verification systems. The material argues that organizations should be able to replace cryptographic algorithms without major infrastructure changes as standards evolve, particularly through NIST’s post-quantum efforts. It also notes that basic liveness checks such as blinking or smiling are vulnerable to high-quality images, videos, and AI-generated deepfakes, prompting the use of layered techniques including passive physiological analysis, active challenges, 3D facial mapping, and texture analysis. Combining adaptable cryptography with advanced liveness verification is presented as necessary because strong cryptography cannot stop biometric spoofing, while liveness checks cannot compensate for compromised encryption. Didit is presented as a platform offering modular, API-based verification workflows, post-quantum readiness, and iBeta Level 1-certified liveness detection to help organizations prepare for evolving quantum and identity fraud risks.
