The methods of hiding information developed for steganography have evolved in the direction of increasing the volume of embedded data, imperceptibility and reliability, preserving the quality of the digital image to go unnoticed. The most important methods combined symmetric or asymmetric cryptography to find security techniques. The purpose of this paper is to show different approaches used for steganography; an exciting combination of mathematical algorithms is showed to keep the essential principles of hiding information. This paper shows a compilation on the development and application of different steganography methods that have been presented in the area of information security to analyze the progress that has been made. On the other hand, this paper described the proposal of a method capable of generating variable alphabets for encoding the message to be hidden in digital images for color models, based on the data collected in the research presented, to increase security in the process of steganography.
