Data Forensics
We build public safety AI data infrastructure.
Dongsimwoo has accumulated approximately 5 years of criminal investigation validation and living lab operation experience through participation in AI Investigation Support R&D and CYBER C.O.P. R&D. We generate high-quality de-identified synthetic data based on actual trial and investigation records, and train AI models on this data to conduct R&D optimized for field operations. Working closely with investigation experts in Republic of Korea's public safety field, we are building a data-driven scientific investigation infrastructure.
Core Capabilities
R&D Projects
R&D Projects
We are developing next-generation investigative analysis platforms as a core participating organization in National Police Agency national R&D projects.
CYBER C.O.P.
Development of Cybercrime Investigation Lead Integrated Analysis and Inference System
A National Police Agency national R&D project (total KRW 24 billion, 2025–2028) launched in April 2025, developing an intelligent investigation and analysis platform to combat major cybercrimes including fraud, phishing, and digital sex crimes. Dongsimwoo is responsible for criminal investigation scenario creation and inference model training dataset construction.
AI Investigation Support R&D
Approximately 5 years of criminal investigation validation and living lab operation
Participating as an expert group in the AI-based criminal investigation support R&D project, we have verified the field applicability of AI investigation support technologies through validation testing and living lab operations at actual investigation sites. The practical know-how and data accumulated through this process represent Dongsimwoo's core competitive advantage.
Narcotics Organized Crime Analysis Research
Collaboration with Seoul Metropolitan Police narcotics investigation and Police Academy virtual asset experts
We maintain continuous communication with experts from the Seoul Metropolitan Police Agency Narcotics Crime Investigation Unit and the Police Investigation Academy virtual asset specialists to thoroughly understand recent narcotics crime trends and methods. Through review of finalized narcotics organized crime case records, we secure and augment data, develop accurate schemas for identifying personnel relationships among organization members, and aim to achieve accuracy metrics for narcotics organized crime personnel relationship identification.
Technology
Core Technologies
We possess proprietary AI technologies for solving practical problems at criminal investigation sites.
HumanNet — Personnel Hierarchy Inference Algorithm
Graph-based criminal organization role inference model
We standardize role hierarchies based on cyber organization operational characteristics — including mastermind, organization management, recruitment, withdrawal, and technical support — and apply HGT (Heterogeneous Graph Transformer)-based message passing by relationship type to generate role embeddings that reflect structural positions and behavioral patterns among individuals.
Person-Case Relational Graph Modeling
Multi-relational investigative graph structure generation
We construct multi-relational graphs based on case, person, identifier, and activity information by integrating heterogeneous data including phone, account, IP, wallet, and platform data. We detect hidden co-conspirators across multiple cases and visualize the patterns of change, expansion, and reorganization in criminal organization structures.
LLM-Based Investigation Record Generation
Synthetic data reflecting the structure, style, and evidence flow of investigation records
We possess large language model (LLM)-based investigation record generation technology that reflects the structure, writing style, and evidence flow of actual investigation records. We automatically generate scenarios reflecting the latest crime trends including voice phishing, investment fraud, online gambling, and digital sex crimes to produce synthetic datasets for AI model training and evaluation.
Investigative Intelligence Data Profiling
Lead analysis system based on cybercrime characteristic analysis
We systematically classify victim petitions, statements, and evidence materials based on cold case scenarios, and build similar case identification guidelines based on multi-victim similar case identification checklists. We support understanding of case structures and related cases through multi-network visualization.
Assets
Core Assets
We possess high-quality datasets and scenarios built based on investigation expert advisory.
Cybercrime Scenario Datasets
We are building comprehensive scenario datasets for each investigation stage based on cybercrime investigation expert advisory. These include scenarios by actual crime type such as online marketplace fraud and online narcotics distribution, along with communication and financial datasets. We are also constructing cold case datasets based on the analysis of cybercrime fraud cases that end as unsolved.
De-identified Synthetic Investigation Data
We generate high-quality de-identified synthetic data (ground truth scenarios) based on actual trial and investigation records secured through AI Investigation Support R&D. We possess proprietary content that enables R&D optimized for field operations by training AI models on this data.
Trial and Investigation Record Review Expertise
We possess expertise in reviewing trial and investigation records, developed in collaboration with narcotics investigation experts. Through review of finalized narcotics organized crime case records, we secure and augment data and develop accurate schemas for identifying personnel relationships among organization members.
Narcotics Crime Trend Intelligence
Through continuous communication with Seoul Metropolitan Police Agency Narcotics Crime Investigation Unit experts and Police Investigation Academy virtual asset specialists, we maintain intelligence on the latest narcotics crime trends and methods. This reflects the latest techniques including money laundering using virtual assets and dark web transactions.
