This paper introduces a novel approach for encoding information in PDF documents or similar files. The proposed encoding involves a dual-step method: firstly, the information is encoded in base64, and subsequently, it is uploaded in a user-selected color, while the rest of the colors contain dummy information. Merging of the encoded segments results in a single QR code. The Literature Review subsection investigates the usage of similar methods for information encoding, followed by a comparison of the luminance of the generated QR code with theoretical expectations. Finally, diverse use cases are presented.The proposed methodology is presented: • Compare the results obtained from the theorical approximation with those acquired in the merged QR code. • Use cases: encoding text sample to obtain a counterfeit system. • Results, contributions, and future work.
