Image Obfuscation in the User-Friendly Sensitive Area with the Use of a Sensor for Smart Devices and Image Processing Techniques

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.
