Locus by AcquisizioniForensi

LOCUS — Forensic acquisition and digital site survey LOCUS turns your iPhone and iPad into a professional tool to document places, objects and events with full technical traceability. Built for technical consultants, law enforcement, expert witnesses, security managers and law firms, the app produces a complete, third-party-verifiable evidence package for every acquisition, in line with forensic best practices. What it does For every photo, video or audio recording, LOCUS automatically builds a cryptographic chain of custody: • Time synchronisation via NTP and RFC 3161 timestamping (with optional eIDAS qualified InfoCert timestamp) • Triple cryptographic hash of the file (MD5, SHA-256, SHA-512) • Device-bound Ed25519 digital signature • GPS geolocation, compass heading and environmental data • Watermark with date/time, coordinates and unique identifier • Preserved EXIF metadata and in-media provenance (inspired by C2PA/JUMBF) • Forensic PDF report and CASE/UCO descriptor • Sealed, self-validating BagIt package (RFC 8493) Independent verification Each acquisition produces a public verification link and can be checked offline with the LOCUS Validator desktop app, without relying on our servers: anyone (opposing expert, prosecutor, judge) can compare hashes, timestamps and signature. Standards ISO/IEC 27037, SWGDE guidelines, RFC 3161 (timestamping), eIDAS, EXIF 2.32, CASE/UCO, BagIt, ISO/IEC 14496-12 for video. Who it's for • Technical consultants and expert witnesses • Law enforcement and investigators • Loss adjusters and insurance experts • Security managers and auditors • Law firms How it works Sign in with your credentials, choose photo, video or audio, optionally enable the qualified timestamp and capture: LOCUS runs the entire pipeline and hands you a package ready to archive and share. Usage is slot-based, with a pool shared across the AcquisizioniForensi.it ecosystem. Note LOCUS documents and seals what you capture transparently: it honestly declares the origin of the data (live capture or system camera) and does not alter the content. The evidentiary assessment remains the responsibility of the judicial authority. LOCUS by AcquisizioniForensi.it — locus.acquisizioniforensi.com
