1. A computer-implemented digital steganography method comprising: providing a target dataset having a binary form, the target data set comprising: a plurality of target data elements, wherein each target data element comprises: a sequence of digital bits; providing a source dataset having a binary form, the source data set comprising: a plurality of source data elements, wherein each source data element comprises: a sequence of digital bits such that the source dataset can be represented in a bitwise representation having a specific start bit for each source data element; and creating a grille dataset configured to map each of the target data elements in the target dataset with a corresponding source data element within the source dataset in accordance with a predefined extraction method, the grille dataset comprising: for each target data element, a corresponding indice indicating the position of the specific start bit within the bitwise representation of the source dataset, irrespective of the bitwise position of each of the source data elements.
