Abstract

Our solution comprises an integrated ecosystem consisting of three coordinated layers designed to eliminate bottlenecks, automate critical processes, and ensure full transparency throughout the lifecycle of meeting minutes. At the base, there is a capture totem equipped with a camera and digitizing tablet, capable of recognizing physical signatures via siamese neural networks and automatically forwarding the minutes to the notary’s back-end system. Next, the notary’s system receives these files, activates language models to generate summaries and identify key information (signatories, decisions, CNPJ, dates), and validates each signature, reducing the notary’s workload and accelerating the process. Immediately after validation, each minute is assigned a cryptographic hash recorded on a private blockchain node. This ensures immutability, traceability, and proof of document integrity at every stage of the workflow. Finally, a mobile app provides the CNPJ holder with a unified interface to track the real-time progress of each minute.

Problem being solved

The process of managing and validating the minutes of NGO, foundation and association board meetings is fragmented, time-consuming and prone to inconsistencies. Each meeting generates minutes that need to be signed manually or electronically by the board members, forwarded to different notary offices and only then are they publicly recognized. This process requires manual checks of the identity and authenticity of signatures, which takes time and human effort, leaves room for errors and makes it difficult for interested parties to monitor the minutes. Furthermore, there is no unified mechanism to automatically extract key information from the text of the minutes, such as participant data, topics discussed or institutional ties, which compromises standardization and speed in decision-making. The lack of traceability regarding who has possession of the document at each stage and transparency regarding when the minutes are made public further increases the risk of fraud and increases uncertainty for all involved. In short, the challenge is to create an integrated, secure and automated flow that combines capture, verification, registration and provision of minutes, reducing rework, ensuring reliability and accelerating the document management process.

How it Works - Submitting a meeting minute

Here is the process of submission of a minute works, step-by-step:

  1. Submission: The user (NGO or foundation member) submits the minute using the kiosk at the notary’s office.
  2. File Verification: The kiosk verifies that the uploaded file is in PDF format and free of executable code or malware.
  3. Photo & Signature Capture: Upon successful verification, the kiosk captures a photo of the user and requests a signature via the graphics tablet.
  4. Photo Validation: The photo is analyzed to ensure it clearly depicts a human face.
  5. Retry or Proceed: If valid, the signature and file are submitted for analysis, and the user is dismissed. If invalid, the system retakes the photo until it meets standards.
  6. LLM & Signature Analysis: The PDF is analyzed by the LLM, and the signature is verified using a neural network.
  7. Data Validation: Key information extracted by the LLM (signatories, personal data, decisions, etc.) is validated by the analysis service. A report highlighting inconsistencies, validated data, and key aspects is generated for the notary.
  8. Notary Review: The notary reviews the LLM-generated data and report, adds relevant comments or corrections, and Image Processingdecides whether to authenticate the document.
  9. Blockchain Registration: If authenticated, the notary adds the minute to their ledger, and a cryptographic hash is recorded on the private blockchain (see [[Project Overview#Blockchain]]).

If the minute is ordinary, that is, contains no decisions that impact/alter the legal structures of the entity the process is completed (Código Civíl Art 59)! Otherwise, the minute must now be submitted to a registry office where the document will be analysed for it’s compliance with the entities internal statute and it’s legality under the Brazilian law. There, the process will follow a similar flow. However, due to the subjective interpretation of the text, greater monitoring by the notary is necessary.

Software

Notary Interface

The Notary can access all minutes through a web application, where they can check the status of the LLM analysis, review the contents, and modify, add, or delete information from any minutes of meetings (MoMs) in their office.
