As for auditory and vocal technology, the vocal method extracts applicants' vocal waves to analyze vocal factors such as utterance time, speed, and volume. In addition, each applicant's answers are analyzed in terms of temporal change to collect vocal spectrum data in real-time. As for verbal technology, voice data are extracted just as in the case of vocal technology. Each applicant's linguistic habits, times of using a particular word, and the like are analyzed to grasp his/her linguistic behaviors and tendencies [20]. Finally, vital (biological) data are collected to grasp applicants’ emotional state and dishonesty based on the fact that the current biological state is related to his/her blood flow and pulse (see Figure 1).

Figure 3 Design of web service structure

The development environment may be divided mainly into the WAS area and Deep Learning area. As shown in Table 2, the development environment is designed and embodied in each specific role. First, the WAS area is based on Linux Ubuntu OS. As for the DBMS, MongoDB of NoSQL, which is commonly used recently, is adopted for more flexible expansion. To embody the asynchronous Single-page Application (SPA) service, Javascript- based VUE web programming technology was applied. GraphQL API is also used for faster and more efficient operations. Second, the Deep Learning area is based on Linux CentOS. As for the DMBS, the relational database MySQL is adopted to apply the JAVA web programming method.

Visual technology extracts 68 points from each applicant's face, analyzes each facial part's delicate movements, and extracts necessary data from the video information, including the applicant’s emotional state, eye movement, facial movement, and head rotation. Based on the extracted data of facial changes, the applicant's feelings are analyzed, such as joy, sadness, anger, distaste, fear, and tension [19].
