In this paper, we propose a pill identification model using engraved text feature and image feature such as shape and color, and compare it with an identification model that does not use engraved text feature to verify the possibility of improving identification performance by improving recognition rate of the engraved text. The data consisted of 100 classes and used 10 images per class. The engraved text feature was acquired through Keras OCR based on deep learning and 1D CNN, and the image feature was acquired through 2D CNN. According to the identification results, the accuracy of the text recognition model was 90%. The accuracy of the comparative model and the proposed model was 91.9% and 97.6%. The accuracy, precision, recall, and F1-score of the proposed model were better than those of the comparative model in terms of statistical significance. As a result, we confirmed that the expansion of the range of feature improved the performance of the identification model.

본 논문에서는 현재 이슈가 되고 있는 개인 정보 보안에 대해서 Keras 라이브러리를 사용하여 개인 정보 관련 데이터를 학습한 후, 한글 인식률 증가된 Tesseract-OCR 활용하여 사람들이 가지고 있는 데이터의 개인 정보 유무를 판단하여 분류한다.
