# Forensic Notes > Court-ready digital notetaking software for investigators. Every note is digitally signed with SHA-512 cryptographic hashing, timestamped, and stored with a complete audit trail. ## About Forensic Notes is a web-based platform built for law enforcement officers, private investigators, digital forensic examiners, corporate security teams, and legal professionals. It replaces Microsoft Word, OneNote, and paper notebooks with tamper-proof digital documentation that meets legal standards of admissibility in the United States, Canada, the United Kingdom, and Australia. The platform was founded by Robert Merriott, a former police officer who experienced firsthand how inadequate documentation tools can undermine investigations and court proceedings. ## Core Capabilities - SHA-512 digital signatures on every note at creation - Trusted timestamps proving exactly when each record was made - Private blockchain anchoring for independent verification - 256-bit AES encryption at rest, TLS 1.2+ in transit - Complete audit trails logging every action by every user - Role-based access control with multi-factor authentication - Progressive Web App (works on any device, any browser) - AI-powered voice-to-text for field documentation - Team collaboration with notebook sharing and case management - Agency branding for professional court-ready reports - Exported PDFs include embedded digital signatures for independent verification ## Free DFIR Tools Forensic Notes provides free, browser-based tools for digital forensics investigators. All tools are 100% client-side — no files or data are uploaded to any server. ### Forensic Hash Calculator URL: https://www.forensicnotes.com/tools/forensic-hash-calculator A free forensic hash calculator that computes MD5, SHA-1, SHA-256, and SHA-512 hash values for files and folders entirely in the browser. No data is uploaded at any point. Key capabilities: - Computes MD5, SHA-1, SHA-256, SHA-512 using the browser's native Web Crypto API - Multi-file and folder drag-and-drop with ZIP extraction (nested ZIPs supported up to 3 levels) - Automatic duplicate file detection — groups files with identical hash values regardless of filename - Hash verification mode — paste a known hash to instantly highlight matching or mismatched files - VirusTotal SHA-256 lookup integration (optional, requires free VT API key) - Per-file forensic report copy and full-session CSV/text export - Algorithm selection remembered between sessions - Results sorted A-Z with ZIP contents nested under parent archive Use cases: forensic chain of custody documentation, evidence integrity verification, disk image validation, duplicate evidence detection, malware triage, sensitive investigation support. Relevant standards: NIST SP 800-101, SWGDE guidelines, Federal Rules of Evidence (FRE 901). ### Forensic Timestamp Decoder URL: https://www.forensicnotes.com/tools/forensic-timestamp-decoder A free forensic timestamp decoder that converts numeric and encoded timestamp values into human-readable dates. Supports 25+ formats including Unix epoch, Windows FILETIME, Chrome/WebKit, Apple HFS+, and more. Key capabilities: - Decodes 25+ timestamp formats with confidence scoring - Bulk text paste to auto-extract all timestamps from logs, registry exports, or forensic reports - File upload support (PDF, DOCX, TXT, CSV, LOG) - Shareable URL for collaboration - No data uploaded — all decoding is client-side ### Forensic IMAGE EXIF Analyzer URL: https://www.forensicnotes.com/tools/forensic-exif-reader A free forensic EXIF metadata viewer that extracts comprehensive metadata from images including EXIF, GPS, XMP, IPTC, camera serial numbers, and edit history. Designed for digital forensics investigations and evidence authentication. Key capabilities: - Extract EXIF, GPS, XMP, IPTC, ICC, and maker notes from JPEG, HEIC, TIFF, DNG, and all major RAW formats (CR2, NEF, ARW, ORF, RW2, RAF, etc.) - SHA-256 hash computation for file integrity verification using Web Crypto API - Automatic duplicate detection — flags byte-identical files by matching SHA-256 hashes - Compare mode — side-by-side comparison of 2 images showing 19 key forensic fields with visual mismatch indicators - Camera and lens serial numbers for device authentication - GPS coordinates with Google Maps integration and KML export - Modification delta card showing time difference between capture and last edit - Edit detection (Photoshop, Lightroom, GIMP, Snapseed, Affinity) with XMP edit history parsing - Anomaly detection: future dates, timestamp conflicts, missing GPS, pre-1990 dates - Timezone selector for timestamp display (full IANA timezone list) - Export options: CSV (all metadata fields), JSON (raw EXIF segments), KML (GPS locations for Google Earth) - All processing happens in browser using Web Workers — no upload, works offline Use cases: image authenticity verification, camera identification, GPS location extraction, timestamp analysis, duplicate image detection, edit history examination, metadata comparison for linking evidence. Relevant standards: SWGDE guidelines for digital image authentication, chain of custody documentation, expert witness testimony preparation. ## Key Pages - Homepage: https://www.forensicnotes.com/ - Free DFIR Tools: https://www.forensicnotes.com/tools - Forensic Hash Calculator: https://www.forensicnotes.com/tools/forensic-hash-calculator - Forensic Timestamp Decoder: https://www.forensicnotes.com/tools/forensic-timestamp-decoder - Forensic IMAGE EXIF Analyzer: https://www.forensicnotes.com/tools/forensic-exif-reader - Features: https://www.forensicnotes.com/features - Digital Signatures: https://www.forensicnotes.com/features/digital-signatures - Pricing: https://www.forensicnotes.com/pricing - For Agencies: https://www.forensicnotes.com/for-agencies - Security & Trust: https://www.forensicnotes.com/trust - Case Studies: https://www.forensicnotes.com/case-studies - Legal Standards: https://www.forensicnotes.com/legal-standards - Why Not Word: https://www.forensicnotes.com/why-not-word - Blog: https://www.forensicnotes.com/blog - Support Hub: https://www.forensicnotes.com/support - About Us: https://www.forensicnotes.com/about-us - Contact: https://www.forensicnotes.com/contact-us - Free Trial: https://www.forensicnotes.com/free-trial ## Who Uses Forensic Notes - Law enforcement agencies and police departments - Private investigation firms - Digital forensic laboratories - Corporate security and compliance teams - Insurance fraud investigators - Legal professionals and litigation support ## Compliance Alignment - SOC 2 Type II compliant hosting infrastructure - Designed to support Federal Rules of Evidence (FRE 901) - Aligned with ISO 17025 traceability standards - Built-in controls aligned with CJIS Security Policy - Privacy-by-design principles consistent with GDPR and PIPEDA ## Contact - Website: https://www.forensicnotes.com - Email: support@forensicnotes.com - Company: TwiceSafe Software Solutions Inc.
