Project Overview

CaseLink is an enterprise-level and secure application designed to manage cases and documents for police departments, law enforcement teams, investigation departments, jury panels, and judicial authorities. The client was searching for a trusted software development company to develop a document management system that caters to the Police Department within the USA.

The application brings case information, evidence, media files, timetables, reports, transcripts, and supporting documents together in one place. Authorized users can create and manage cases, organize crime-related information, handle different types of media, manage evidence, prepare transcripts, and export case information when required.

CaseLink can handle large volumes of data and media, including cases of up to 1TB. Different levels of permissions help protect sensitive information and ensure that users can only access the data relevant to their role.

Business Challenges

1. Fragmented Case and Evidence Management

Case details, evidence, documents, and multimedia are stored across many storage devices and systems by police departments and investigation groups. It makes case tracking complicated and creates a risk of missing some information.

2. Handling Large-Size Files

In investigation cases, there may be huge video/audio files where each file is over 1GB, and the whole case will reach up to 500GB to 1TB. Traditional methods of file storage and browser-based video players raise many challenges in terms of storage, performance, uploading, downloading, and video playing.

3. Various Multimedia Formats

Many kinds of file formats, such as MP4, MOV, 3GP, WAV, MP3, JPG, JPEG, PNG, PPT, PDF, XLSX, etc., are handled by investigation teams. They need to handle and view all these types of files from one web application.

4. High Security Needs

CaseLink handles highly confidential crime investigation and legal information. Accessing them unauthorizedly, leaking, changing, or losing these files or information may have severe impacts. So, this application needs multiple levels of security and authorization.

5. Complicated Timeline for Investigation

The crime investigation requires various incidents, locations, devices, evidence files, and events happening at different times. It becomes tough for the investigators and jurors to comprehend the entire process.

6. Manual Process of Videos and Evidence

The investigator may require cropping of videos, creating transcripts, editing captioning, keyword spotting, and making evidence ready for the hearing in courts.

Our Solutions

To overcome the challenges of fragmented case management, large media files, security requirements, and complex investigation workflows, we developed CaseLink as a centralized and secure legal case management platform.

The solution combines case management, evidence organization, media processing, document management, investigation timelines, transcription, reporting, and secure collaboration into a single platform.

Centralized Case & Investigation Management

The platform provides a centralized workspace where authorized users can create cases, manage case stories, add investigation details, organize evidence, and build complete incident timelines. This enables investigators and justice officials to access all relevant case information from one location.

Secure Multi-Tenant Access

CaseLink supports multiple departments and user roles with configurable permissions. Department administrators can manage users and access rights, while department users receive customized permissions based on organizational requirements. Jury members can access required case information through controlled view-only permissions.

Large-Scale Media Management

A dedicated media management solution enables the platform to handle large video and audio files. Files are securely stored in cloud infrastructure and processed in smaller chunks to improve streaming performance and reliability.

Advanced Video Processing & Streaming

Users can stream multiple videos simultaneously, crop videos using start and end timestamps, generate transcripts, edit captions, add keyword highlights, and create watermarked media. A specialized streaming module allows up to 20 videos to be played simultaneously.

Automated Transcription

Video and audio files can be processed in the background to generate automated transcripts. Users can review and edit transcripts, manage captions, and download subtitle files for use during investigation and court proceedings.

Secure Document & Evidence Management

Case files are organized using structured folders and encrypted storage. Access to individual files is controlled through role-based permissions, ensuring that confidential evidence and documents are only available to authorized users.

Automated Case Reporting & Export

The platform can generate comprehensive PDF documentation containing case timelines, file information, transcripts, folders, bookmarks, and supporting evidence. This allows investigation teams to prepare complete case documentation for hearings and internal reporting.

Key Benefits
