Information Security Vulnerabilities Using Steganography as the Art of Hiding Information

Due to advances in technological tools, most of the information is kept electronically and because of this information security has become a fundamental issue. Steganography is the art of hiding information and an effort to hide the existence of the embedded information, it serves as a better way to protect the message than cryptography, which only hides the content of the message, not the existence of the message, allowing the original message is hidden within a digital medium that serves as transport, so that the changes that occur in it are not detectable. Consequently, steganography is a useful tool that allows the covert transmission of information through the communication channel, by combining the hidden message with the original message, originating the hidden image, which is difficult to detect without recovering it. The purpose of this bibliographical review is to know steganography as a method to hide information and to determine the various modes of application in the digital area to hide data and information from unauthorized users, thus achieving that the exchange of information is a discreet process and insurance for those interested.
