Blindaje

Every week, a market vendor in Lima gets the same WhatsApp voice note: pay S/ 200 or your stall doesn't open. She thinks she is alone. She isn't: the same voice is threatening a mototaxi driver in another district, and the same Yape account is collecting from other businesses. Nobody connects them, because the evidence lives on the phones of people who never meet. Peru filed 13,892 extortion reports from January to July 2026, and many victims never report at all, afraid of retaliation. Blindaje turns those isolated victims into community intelligence. FOR THE VICTIM: an Android app disguised as an ordinary sales notebook that really works. A secret entry and PIN open private notes; a decoy PIN opens believable empty ones. She shares voice notes, photos, videos and messages straight from WhatsApp. Everything uploads encrypted. No name, ID or phone number is asked. Meta's models transcribe and read the evidence, and she gets a dated report with the SHA-256 hash of every piece, as a PDF for the police. FOR THE INTELLIGENCE TEAM: a console that finds the cases that come from the same gang. The engine compares the traces a gang leaves (the same voice from different numbers, the same payment account, the same photos, the same script) across the cases whose owners opted in. Agents on Muse Spark explain every proposed link with verified citations and profile each network into facts and hypotheses. A person approves every link, and police receive a documented case file. FOR THE PUBLIC: a district map of Lima and Callao. Ranges, never addresses. THE DEMO, ON THE LIVE SYSTEM: 10 fictitious reports, one of them uploaded live from the phone. The agents propose 20 links, a reviewer confirms 14, and two separate gangs emerge, including one that uses another gang's name but pays a different account. A planted fake with a cloned voice is caught by Meta's AudioSeal and Video Seal watermarks and never enters a network. Ten isolated reports, two gangs revealed. MEASURED: correct case ranked first by voice 100%, 0.19 false links per 100 comparisons, 98.3% of case fields correct, 49/49 agent claims backed by verifiable citations, and a test proving a victim never sees another victim's data. TRY IT: https://blindaje-console.vigiaperu.workers.dev, read-only judge login jurado@demo.blindaje.test / Jurado-Demo-2026. Every person, voice and case is fictitious. Built solo in 8 days. Next: a pilot with a Lima business guild, after a legal review under Peru's data protection law. No one should face extortion alone.
