Quantum Gatekeeper uses VQC for secure image steganography with multi-factor context

By PulseAugur Editorial · Summary by gemini-2.5-flash-lite from 2 sources

Researchers have developed a novel steganography framework called Quantum Gatekeeper, which embeds data within images using a combination of cryptographic techniques and quantum circuits. Successful extraction of hidden information requires precise matching of a password, shared secret, context string, and image signature. The system utilizes variational quantum circuits (VQC) to derive encryption keys and is evaluated on IBM's superconducting quantum hardware to assess its performance under physical noise. AI
