Abstract: In this modern information technology era, automatically extracting information from identity documents is applied in bank, telecommunications, healthcare, hotels, and more. This paper uses of computer vision techniques to build a system which extracts information from identity documents for eKYC system. There are three main steps: Identifying identity documents, locating information and extracting information. In particular, identifying indentity cards and locating information are accomplished by basic image processing techniques to increase the speed of the entire system. At the information extraction step, the achievements in text recognition on complex background are used to increase accuracy. After development and experimentation, the system has achieved a relatively high degree of accuracy. The accuracy of the whole system is over 90%, thisresultcan be applied to the eKYC system of banks and credit institutions.
