Abstract: Highlights•Laguerre transform performs integer based calculation and therefore the operations are faster.•The binary factorization of the transform matrix enables efficient hardware implementation.•The computational complexity of the Laguerre transform is O (n × log(n)).•Proposed method supports widely used image formats such as BMP, PPM, PGM, and TIFF.•Variable payload with considerable stego-image's quality distortion is achieved.•StegExpose tool ensures that the robustness of the stego-images is very high.
