[001] The invention belongs to the area of ​​digital security, specifically to systems and methods for collecting, preserving, authenticating, and verifying digital information. The invention is applicable in environments where the integrity and authenticity of digital data are fundamental, such as in the collection of digital evidence for judicial and extrajudicial proceedings and online information audits. The method proposes a webview component as a technical differentiator for advanced control and security in web browsing environments, combined with the use of blockchain technology, offering a robust and reliable process. The invention falls under categories G06F 17 / 00 Digital computing or data processing equipment or methods, specially adapted for specific functions (information retrieval, database structures or file system structures of the same G06F 16 / 00)

[2019] .01] and G06F 21 / 00 Security provisions for protecting computers, their components, programs or data against unauthorized activity [2013.01]. Fundamentals of the invention

[002] Currently, the preservation of digital information is carried out through various methods, such as screenshots, video recordings, and digital testimonies stored on centralized servers. Although these techniques provide a basic way to record data, they are often vulnerable to tampering, compromising their validity in legal situations and audits. Furthermore, existing market solutions operate online, i.e., remotely, while the method described here is performed through local browsing, combined with the recording of information on a blockchain.

[003] The present invention consists of an innovative system for collecting, preserving and recording digital information, which differs significantly from other solutions on the market by using a local navigation method combined with Blockchain technology to guarantee authenticity, origin and Petition 870240111484, dated 12 / 31 / 2024, page 14 / 21 / 5 immutability of captured data. This system not only stores digital information, but also offers an additional level of security and reliability by ensuring that the content cannot be altered without being detected.

[004] When searching the INPI database for patents similar to the invention, the following strategies were used. Strategy 1: advanced search using the category (IPC - International Patent Classification) G06F 17 / 00 (Digital computing or equipment or methods for processing data, especially adapted for specific functions - information retrieval, database structures or file system structures of the same G06F 16 / 00) [2019.01] in conjunction with the keyword “capture”. The search returned no results. Strategy 2: advanced search using the category (IPC) G06F 21 / 00 Security provisions for protecting computers, components thereof, programs or data against unauthorized activity [2013.01] in conjunction with the keyword “capture”. The search returned no results. Strategy 3: advanced search looking for the following arguments in the invention title “METHOD AND CAPTURE AND DATA AND INTERNET”.This search returned one result: (request) BR 10 2019 017526 5 (deposit) 22 / 08 / . Analyzing this result, significant differences were identified between the processes, since the aforementioned request concerns a method for capturing and preserving internet browsing data, but it differs from the method described in this request by being essentially based on streaming security technology. Despite focusing on the same problem, the two methods differ in how browsing occurs; in request BR 10 2019 017526 5, browsing occurs remotely, while in this request, all capture originates from local browsing. [0051 The invention described in this application solves the problem of the fragility of information present in the virtual environment by combining a form of local browsing with registration via Blockchain to guarantee the immutability of the capture result. The main innovation lies in combining the use of local browsing in the way navigation is performed with the registration of immutability via blockchain. Description of the invention Petition 870240111484, dated 12 / 31 / 2024, page 15 / 21 / 5

[006] The described method begins with the installation of software developed to operate securely and autonomously on the user's device. The software is written in a low-level language to prevent any vulnerabilities from altering the content accessed during browsing and to ensure granular control of system resources. Subsequently, an integrity validation is performed using executable hashes and digital verifications.

[007] The main technical difference of the invention is the use of a webview component as a controlled navigation environment, configured to operate in restricted mode, without permissions for extensions or execution of third-party scripts. The webview component, implemented with frameworks such as Electron or CEF (Chromium Embedded Framework), allows navigation by the user, identifying their commands and fully encapsulating the navigation interface, blocking external manipulations. Commands such as F12, Esc and the right mouse button are disabled, ensuring that the displayed content is not altered during capture.

[008] During navigation, the system captures a comprehensive range of metadata relating to user commands directly from the webview component, including URLs and browsing history. In addition, the system performs WHOIS lookups for each domain accessed and validates SSL certificates to ensure secure connections.

[009] During navigation, the screens accessed by the user are captured at high frequency, as well as the audio outputs. The screenshots are stored in MP4 format, and the audio is synchronized with the images to provide complete proof.

[0010] After the user commands the end of navigation, all collected information is compiled into an MP4 video file. This file is digitally signed with an electronic certificate and subjected to a hash calculation, such as MD5, to ensure the integrity of the content.

[0011] The generated hash is then recorded on a public blockchain, such as Ethereum, EOS, or Bitcoin, using a digital signature generated locally by the software. Petition 870240111484, dated 12 / 31 / 2024, page 16 / 21 / 5

[0012] After the registration process is complete, a copy of the signed MP4 file is saved in the cloud, and a web page containing the information captured during browsing is created by the system for review at any time. It is also possible to export the information from the web page to a report in PDF format. Examples of embodiments of the invention

[0013] The invention offers a robust method for collecting and preserving digital evidence, using a browsing environment controlled by a webview component and the immutability provided by Blockchain technology. This system fills a critical gap in digital security, providing a reliable and secure solution for collecting digital evidence, meeting legal requirements and ensuring the integrity of the evidence collected.

[0014] The present invention is situated in the field of digital security and electronic evidence collection. The proposal offers a robust method for capturing, validating, and recording digital evidence in web browsing environments, using a webview component as a technical differentiator for advanced control and security.

[0015] The invention described differs from other existing solutions, primarily by combining a system equipped with a webview component, thus creating a controlled environment for local browsing, with the certification of the capture result via Blockchain.

[0016] The use of the system with a webview component ensures that the user navigates in an isolated and secure environment, eliminating the vulnerabilities common in traditional browsers. From this environment, it is possible for the user to perform a comprehensive and contextual capture in real time, a capture that includes graphical visualizations, audio, user interactions, and metadata related to the capture, resulting in robust evidence.

[0017] By combining local and controlled browsing with the use of blockchain to record the hash of the generated file, an additional layer of security is provided, making the file immutable and easily verifiable, something not found in other solutions. Petition 870240111484, dated 12 / 31 / 2024, page 17 / 21 / 5 competitors. After capture, the capture session data is securely stored in an encrypted cloud, allowing verification of the captured and recorded data.

[0018] Capturing digital evidence faces challenges such as browser manipulation, malicious code execution, and difficulty in verifying the authenticity of the collected data. Traditional methods, based on screen recording or log collection, are vulnerable to tampering. The present invention overcomes these limitations through the strategic use of a system with a webview component embedded in proprietary software, which operates in a controlled and monitored execution environment, and combines the result of this browsing with registration via Blockchain to ensure the immutability of the capture result.
