We introduce a groundbreaking steganographic technique that merges non-linear cost evaluation methods with binary triangular matrix structures to achieve superior data concealment in color images. Our approach tackles the inherent weaknesses of conventional linear cost models by implementing a multiplicative framework that more effectively maintains the statistical characteristics of images while optimizing embedding performance. The integration of structured binary matrices enables intelligent position selection through organized randomization, preserving both visual fidelity and cryptographic security. Our methodology incorporates sophisticated texture evaluation, self-adjusting parameter tuning, and multi-channel analysis to deliver outstanding results across various image categories. Through rigorous testing, we demonstrate remarkable improvements over current leading methods, achieving average PSNR values of 52.34 dB and SSIM scores of 0.9847 across standardized test collections from multiple image databases. The system exhibits substantially enhanced resilience against contemporary steganalysis tools while supporting high embedding rates up to 0.8 bits per pixel with strengthened security assurances.
