Provloc
Every coordinate becomes legally valid proof.
Provloc signs and timestamps each GPS position the moment it's captured. It becomes proof of where and when that no one can forge or alter afterward.
Each record is written immutably to AreaChain, forming a complete digital chain of custody, exactly as articles 158-A to 158-F of the Brazilian Code of Criminal Procedure require.
What is Provloc
Areatec Provloc is the first Brazilian geolocation certification solution with legal validity, based on cryptographic position certification and digital chain of custody in compliance with the Brazilian Code of Criminal Procedure.
What is Provloc
Provloc is Areatec's authenticated geolocation system that solves a critical problem of the digital age: how to prove that an event actually happened at a specific location and time. Unlike conventional GPS, whose signals can be easily spoofed by location spoofing techniques, Provloc applies advanced location authentication to validate each coordinate at the exact moment of capture.
The result is a cryptographic GEO-TAG that associates position, timestamp, and hash of the captured file in a verifiable digital certificate. This certificate is then immutably recorded on AreaChain (Areatec's proprietary immutable ledger), creating a legally valid proof of location that can be audited by any interested party without relying on centralized infrastructure.
Provloc is the pioneering solution in Brazil for geographic position certification, developed to serve everything from traffic enforcement to applications in insurance, agribusiness, judicial forensics, logistics, and smart cities.
How It Works
From signal capture to immutable proof, each step guarantees the authenticity and integrity of the registered position.
Authenticated Capture
The device's satellite positioning receiver captures signals from multiple constellations (GPS, GLONASS, BeiDou) with advanced cryptographic authentication at the signal layer. Each observation is validated against security keys to ensure the signals have not been manipulated.
Cryptographic Certification
The authenticated position, high-precision timestamp, and digital signature of the associated file (photo, video, document) are combined into a signed digital certificate. This certificate constitutes the Provloc cryptographic GEO-TAG.
Anti-Spoofing Validation
Proprietary Aretron AI algorithms analyze the consistency of received signals, detecting position spoofing attempts (Deep Fake Positioning). Anomalous signals are identified and rejected prior to certification.
Immutable Record
The validated certificate is immutably recorded on AreaChain, Areatec's proprietary immutable ledger. Each record receives a timestamp seal, certificate signature, and reference to the previous record, creating an inviolable digital chain of custody.
Advanced Anti-Spoofing Protection
Position spoofing (GPS location spoofing) is a real threat that compromises the reliability of any location-based system. Accessible location spoofing equipment allows a device to report being anywhere in the world, invalidating evidence, enabling insurance fraud, and manipulating logistical records.
Provloc implements multiple layers of protection against Deep Fake Positioning. Cryptographic authentication of geolocation signals at the navigation layer ensures that only legitimate signals from the constellations are accepted. Aretron AI algorithms analyze temporal, spatial, and power consistency patterns of received signals, identifying anomalies characteristic of location spoofing attacks and falsification attempts.
Additionally, the system cross-references data from multiple sources (inertial, barometric, multi-source verification) for independent validation of the satellite positioning, making it virtually impossible to deceive Provloc with spoofed signals.

Digital Chain of Custody
The Brazilian Code of Criminal Procedure (articles 158-A to 158-F, included by Law 13.964/2019) establishes strict requirements for the preservation of digital evidence. Provloc was designed from its conception to fully meet these requirements, ensuring that each geolocated evidence maintains its intact chain of custody from capture to presentation in court.
The system automatically records each stage of the evidence lifecycle: collection (with agent and device identification), packaging (encryption and hash), transport (encrypted channel), receipt (integrity validation), processing (Aretron AI analysis), and storage (AreaChain). Any access or manipulation generates an auditable and immutable log.
This native compliance eliminates the need for manual preservation procedures and drastically reduces the risk of procedural nullity due to a broken chain of custody, one of the main defense arguments in administrative and judicial proceedings.

SDK and Integration API
Provloc provides a complete SDK for integration into third-party applications. Developers can incorporate authenticated position certification into any mobile app, embedded system, or web platform with just a few lines of code.
The REST verification API allows any interested party to validate the authenticity of a Provloc certificate without the need for proprietary software. Simply submit the certificate to the verification endpoint to obtain cryptographic confirmation of authenticity, integrity, and timestamp.
val provloc = Provloc.init(apiKey)
