Forensic Witness - Send File Request

What Is Forensic Witness?

Forensic Witness is a powerful feature within Forensic Notes that enables investigators to send secure file requests directly to witnesses, victims, and third parties. Rather than relying on unsecured email attachments, personal cloud storage links, or physical media transfers, Forensic Witness provides a purpose-built channel for collecting digital evidence while maintaining a verifiable chain of custody from the moment a file is uploaded.

In modern investigations, digital evidence frequently originates from individuals outside your organization. A witness may have captured video on their smartphone, a complainant may possess relevant documents, or a third-party vendor may need to supply records. Forensic Witness solves the problem of securely collecting these files without compromising evidentiary integrity.

How Forensic Witness Works

The Forensic Witness workflow is designed to be straightforward for both the investigator and the file provider. The entire process can be completed in just a few steps.

Step 1: Create and Send a File Request

From within Forensic Notes, investigators create a new file request by specifying the recipient's name and email address. You can include a personalized message explaining what files are needed and why. The system generates a unique, secure link that is emailed directly to the recipient. Each request is logged with a timestamp, the requesting officer's identity, and a unique reference number for tracking purposes.

Step 2: Witness Receives the Secure Link

The witness or third party receives an email containing a secure link. They do not need to create an account, download any software, or have any prior familiarity with Forensic Notes. The link directs them to a secure upload page where they can review the investigator's instructions and prepare their files for submission.

Step 3: Secure File Upload

The recipient uploads their files through the secure portal. All transfers are encrypted in transit using TLS encryption, ensuring that files cannot be intercepted during transmission. The system supports a wide range of file types, including photos, videos, documents, audio recordings, and other common formats. Once uploaded, the files are immediately associated with the corresponding case and the original file request.

Step 4: Automatic Documentation and Chain of Custody

Upon receipt, Forensic Notes automatically records critical metadata: the date and time of upload, the IP address of the uploader, the file hash values, and the file sizes. This information is digitally signed and timestamped, creating an immutable audit record that establishes when the files were received and confirms they have not been altered since submission.

Key Benefits of Forensic Witness

Maintaining Chain of Custody

One of the most significant challenges in digital evidence collection is establishing and maintaining a clear chain of custody. When files are transferred via email, USB drives, or consumer file-sharing services, there is no verifiable record of when the file was sent, whether it was altered in transit, or who had access to it along the way. Forensic Witness eliminates these concerns by creating an automated, tamper-evident record of every file transfer. Each upload is hashed, timestamped, and linked to the original request, providing a defensible chain of custody that will withstand scrutiny in court.

Secure Transfer Protocol

All file transfers through Forensic Witness are encrypted end-to-end. Unlike email attachments, which can be intercepted, forwarded, or stored on intermediate servers without encryption, Forensic Witness ensures that files are protected from the moment they leave the sender's device until they are securely stored within your Forensic Notes account. This level of security is essential when handling sensitive evidence such as victim photographs, confidential financial records, or classified documents.

Complete Audit Trail

Every action taken within the Forensic Witness workflow is logged and auditable. Investigators can review when a request was sent, when the recipient opened the link, when files were uploaded, and when they were accessed by authorized personnel. This comprehensive audit trail provides transparency and accountability at every stage of the evidence collection process, which is invaluable during disclosure proceedings and court testimony.

Ease of Use for Recipients

Forensic Witness was designed with the non-technical user in mind. Witnesses and third parties do not need to install applications, create accounts, or navigate complex interfaces. The upload process is as simple as clicking a link and selecting files. This reduces friction and increases the likelihood that requested evidence will be submitted promptly and completely.

Use Cases

Witness Evidence Collection

A patrol officer responds to a traffic collision and learns that a bystander captured the incident on their dashcam. Rather than asking the witness to email the footage or hand over their memory card, the officer can send a Forensic Witness request on the spot. The witness uploads the video at their convenience, and the footage is automatically logged, hashed, and secured within the case file.

Victim Statement Documentation

In cases involving harassment or threats, victims often have screenshots, text messages, or social media posts they wish to provide as evidence. Forensic Witness allows investigators to request these files securely, ensuring that the digital evidence is preserved in its original form with proper documentation of when and how it was received.

Third-Party Records Requests

Investigators frequently need to obtain records from businesses, financial institutions, or service providers. Forensic Witness provides a secure, documented method for third parties to submit requested records, complete with an audit trail that confirms the records were received directly from the authorized source.

Internal Affairs and Compliance

Internal affairs investigators can use Forensic Witness to collect documents, recordings, or other files from officers or staff members under review. The secure, auditable nature of the transfer ensures that all parties are protected and that the integrity of the investigation is maintained.

Why Forensic Witness Matters

The integrity of digital evidence is only as strong as the process used to collect and preserve it. Traditional methods of evidence transfer, including email, physical media, and consumer cloud storage, introduce vulnerabilities that can be exploited by defense counsel to challenge the admissibility of evidence. Forensic Witness provides a professionally designed, legally defensible solution that protects both the evidence and the investigator.

By integrating secure file collection directly into your investigation workflow, Forensic Witness saves time, reduces administrative burden, and ensures that every piece of digital evidence you collect meets the highest standards of integrity and traceability.
