Abstract

There are many different sensors such as gyroscope sensor, accelerometer sensor, and light sensor for smart devices. These sensors are applied in many fields such as health and medicine, education, augmented reality, and arts. This study aimed to create user-friendly artistic sensibility related to images in the sensitive areas needed for privacy protection by using a sensor in a smart phone and image processing techniques such as contour extraction, blurring, blending, and brightness adjustment. In many cases, the focus was placed on the matter that techniques such as blurring, pixelization, and low-resolution were used for images in the sensitive area needed for privacy protection so that the related area could not be recognized. The phenomenon of image transformation, which suddenly occurs in this way, can cause irritation to smart device users when they view it. In this context, this study showed the possibility of user-friendly image obfuscation through the reflection of artistic sensibility along with the purpose of privacy protection through the fusion of image obfuscation techniques for privacy protection and artistic sensibility.

Highlights

According to the development of digital devices and the release of many different smart phones and wearable devices including smart glass, the issue of protecting personal information has emerged as a much more important topic
This study suggests the method for the visualization of image distortion in the sensitive area through the refection of a smart sensor and artistic sensibility and shows an example of visual-perceptual realization through blur methods
In many cases of the security area such as CCTV, the method which distorts images is largely used through obfuscation techniques such as mosaic, blurring, pixelization, and low resolution to protect individual privacy

Summary

Introduction

According to the development of digital devices and the release of many different smart phones and wearable devices including smart glass, the issue of protecting personal information has emerged as a much more important topic. It is necessary to develop image distortion techniques to minimize the infringement of user sensibility and protect their privacy For this reason, this study suggests the method for the visualization of image distortion in the sensitive area through the refection of a smart sensor and artistic sensibility and shows an example of visual-perceptual realization through blur methods. This study suggests the method for the visualization of image distortion in the sensitive area through the refection of a smart sensor and artistic sensibility and shows an example of visual-perceptual realization through blur methods This is expected to be an important study in that it could be importantly connected to the immersion of smart device users who consider sensible and sensual things important, minimize users’ stress, and relieve their fatigue.
