Available in Classic and VPC

CLOVA OCR > Domain on the NAVER Cloud Platform enables you to create and manage Document domains. These domains use a machine learning–based text recognition engine to automatically extract input data as key–value pairs. Document OCR domains support documents such as ID cards, certificates, and bank statements that may contain sensitive information. You must complete a prior application review before using this feature. The service provides guidance on securely handling personal and sensitive information through prior approval, including reference architectures.
This section explains how to create and use a Document-type domain. For details on viewing, deleting, and copying domain lists, as well as on integrating with API Gateway,see Domain.
