Abstract

As the limitations of the passive recognition domain, which is not guaranteed transparency of the operation process, AI technology has a vulnerability that depends on the data. Human error is inherent because raw data for artificial intelligence learning must be processed and inspected manually to secure data quality for the advancement of AI learning. In this study, we examine the necessity of learning data management before machine learning by analyzing inaccurate cases of AI learning data and cyber security attack method through the approach from cyber security perspective. In order to verify the learning data integrity, this paper presents the direction of data-preserving artificial intelligence system, a blockchain-based learning data environment model. The proposed method is expected to prevent the threats such as cyber attack and data corruption in providing and using data in the open network for data processing and raw data collection.

인공지능 기술은 작동과정에 대한 투명성이 보장되지 않는 수동적 인식 영역에 제한되는 한계점으로 인해, AI가 학습하는 데이터에 의존적인 취약점을 갖는다. 인공지능 학습을 위한 원시데이터는 AI 학습의 고도화를 위한 데이터 품질 확보를 위해 수작업으로 가공과 검수를 해야 하기에 인적 오류가 내재되어 있으며, 데이터의 훼손, 불완전함, 원시데이터와의 차이 등으로 인해 가공데이터를 통한 AI 학습 시 예상 치 못한 결과값을 도출할 수 있다. 이에 본 연구에서는 사이버 보안 관점에서의 접근을 통한 AI 학습데이터의 부정확한 사례 및 사이버보안 공격 방법 분석을 통해 기계학습 전 학습데이터 관리의 필요성을 살펴보고, 학습 데이터 무결성 검증을 위해 블록체인 기반의 학습데이터 환경 모델인 Data-preserving 인공지능 시스템 구축 방향을 제시한다. Data-preserving AI 학습환경 모델은 AI 학습데이터 제공 전 변조되지 않은 데이터로 학습됨을 보장 하여 데이터 가공 시 및 원시데이터 수집을 위한 오픈 네트워크에서의 데이터 제공 및 활용 시 있을 수 있는 사이버 공격, 데이터 변질 등의 위협을 사전에 방지할 수 있을 것으로 기대된다.
