Secure communication often leaves metadata trails. Encoding in thermal noise provides plausible deniability.
Package as an Arduino shield or Python library with simple send/receive API. Target air-gapped systems first.
Government contractors and infosec firms pay for novel steganography methods that bypass deep packet inspection.
MVP: Command-line tool that modulates noise patterns on USB ports. Validate with academic partners.
Risk: Niche too specialized without clear commercial use beyond research labs.
