In the real world of law enforcement and vigilance operations, evidence does not arrive in tidy, clean JSON APIs.
Evidence arrives as dog-eared, carbon-copied paper First Information Reports (FIRs) stamped with court seals; blurry photographs recovered from a seized mobile device; five-hundred-page bank statements in PDF with rotated tables; and raw text dumps of telecommunication Call Detail Records (CDRs) containing lakhs of rows.
Historically, preparing this material for analysis required junior sub-inspectors and forensic clerks to manually type data into spreadsheets—a process prone to transcription errors, missing leads, and agonizing delays.
Anvexer solves this with a Multi-Modal Unified Ingestion Engine.
1. Paper FIRs & Scanned Chargesheets
Police FIRs and judicial orders present distinct OCR challenges: they often combine printed boilerplates with handwritten Hindi or English notes, degraded carbon-paper ink, and skewed angles.
Anvexer applies specialized pre-processing: * Adaptive Binarization & De-skewing: Flattens curved pages and removes ink bleed-through. * Dual-Language Hindi/English OCR: Accurately recognizes regional language terminology (e.g., “Panchama”, “Malhana”, “Zabtishuda”) and extracts complainant names, suspect aliases, sections of law, and seizing officer designations. * Table Reconstruction: Scanned bank ledgers and property seizure schedules are converted back into tabular data while preserving column alignments.
2. Evidence Photographs & EXIF GPS Vision AI
When investigators seize mobile phones or cameras, the photo roll often holds crucial temporal and spatial clues. Anvexer’s Vision AI pipeline processes images automatically:
- Scene & Content Recognition: Recognizes vehicle license plates, storefront signage, passports, and handwritten diary pages without manual sorting.
- EXIF Metadata Plotting: Where camera sensors recorded metadata, Anvexer extracts capture timestamps and precise GPS latitude/longitude coordinates, placing the photograph onto an offline tactical movement map.
- Chronological Assembly: Photographs are automatically correlated against phone call timestamps and flight records, establishing an undisputed pattern-of-life timeline.
3. Call Detail Records (CDRs) & Tower Mapping
Telecommunication records provide the structural backbone of associate tracking. Anvexer features dedicated CDR parsers for major telecom formats:
- Automated Subscriber Joining: Links raw telephone numbers with subscriber registration identity forms (CAFs) and IMEI handset histories.
- Frequent Contact Frequency: Automatically highlights communication spikes preceding and immediately following key criminal events.
- Cell Tower & CDR Spatial Mapping: Tower locations from the call records placed on the offline map to verify alibis and prove physical proximity between co-conspirators.
Unified Intelligence from Fractured Evidence
By ingesting disparate evidence streams through one single upload screen, Anvexer breaks down evidentiary silos.
A phone number found written on a paper slip inside a seized wallet is automatically linked to a CDR record from a co-accused's phone, which in turn maps to a director on a corporate filing.
The investigator sees one coherent picture, enabling teams to build source-cited case files at speeds human teams alone cannot achieve.
