ABSTRACT Bit Plane Complexity Segmentation (BPCS) digital picture steganography is a technique to hide data inside an image file. BPCS achieves high embedding rates with low distortion based on the theory that noise-like regions in an image’s bit-planes can be replaced with noise-like secret data without significant loss in image quality. . In... Continue Reading
