Abstract: A side-channel encoding method for an electronic device is provided. The side-channel encoding method includes converting an original image into a down image by downscaling the original image, converting the down image into an up image by upscaling the down image, calculating a pixel-specific luminance variation between the original image and the up image by using a local average luminance for each pixel included in the original image, converting the pixel-specific luminance variation into a first variation binary signal by binarizing the luminance variation, converting the first variation binary signal into a second variation binary signal by simplifying the first variation binary signal, and outputting the second variation binary signal by including the second variation binary signal in the down image.

Abstract translation: 提供了一种用于电子设备的侧信道编码方法。 侧信道编码方法包括：通过对原始图像进行缩小，将原始图像转换为下降图像，通过放大下降图像将下行图像转换成上行图像，计算原始图像与上位图像之间的像素特定亮度变化 通过使用原始图像中包含的每个像素的局部平均亮度，通过二值化亮度变化将像素特定亮度变化转换为第一变化二进制信号，通过简化第一变化二进制信号将第一变化二进制信号转换为第二变化二进制信号 并且通过在下降图像中包括第二变化二进制信号来输出第二变化二进制信号。
