Seoul, South Korea - DataStreams has announced a digital forensic solution based on AI technology that aims to revolutionize the digital investigation process. Led by CEO Youngsang Lee, this data-centric company introduced the solution at the ‘1st Korean Forensic Society Paper Competition’ held at the law firm Sejong on October 28.
Dongwook Lee, a senior researcher at DataStreams, led the study. He provided a paper titled "A Study on Digital Forensics with LLM and RAG," which demonstrated how large language models (LLMs) and search-augmented generation (RAG) can enhance the efficiency of digital forensic investigations.
This technology aims to clarify the relationships between digital pieces of evidence by vectorizing them and representing them in graphs. The goal is to build a system that allows investigators to quickly find necessary information even amid complex investigative processes. The system reduces repetitive and time-consuming tasks, allowing investigators to focus on detecting and analyzing more critical and valuable evidence.
In particular, DataStreams’ research emphasizes strengthening automated digital forensic investigation methods. By combining AI and data integration technology, the solution can process large volumes of structured and unstructured data in real time, potentially transforming investigative environments. Senior researcher Dongwook Lee anticipates that this technology will shift the digital forensic paradigm and enhance investigation outcomes.
The event was attended by about 50 stakeholders, including Youngdae Kim, president of the Korean Forensic Society; Jungryul Park, director of the Korea Copyright Protection Agency; and Youngsang Lee, CEO of DataStreams. The competition, focused on “AI and Digital Forensics,” allowed participants to discuss various strategies and technologies. Notably, Lee Jeong-hoon, a student from Inje University, received the grand prize, gaining attention for his contributions. Interest in digital forensics continues to grow, with over 500 candidates from various age groups registering for recent certification examinations. The Korean Forensic Society plans to continue exploring methods to advance the field of digital forensics using artificial intelligence.
