Abstract

Images are one of the most popular media used for information exchange today, where users and the need for image use are increasingly needed, so the image quality in conveying information must be better so that it can be more easily understood and accepted by the human mind. So in this case, the image needs security to secure the information contained in it so that its confidentiality is maintained. Data security is very important in maintaining the confidentiality of information, especially those that contain very important information and can only be known by certain parties, especially if it is sent via public networks. Cryptography is the science and art of maintaining the confidentiality of the pedant by converting it into an unrecognizable form, one of the most popular algorithms used in solving this problem is the base64 and rijendel algorithms which are also known as AES. Image is an information medium, it is because the image is able to accommodate an incident in the form of a photo well, but in this case a large image has problems in storage and also in delivery, in this situation the writer wants to apply the algorithm contained in cryptography to secure the image on when stored or want to be sent so that information does not leak and the confidentiality of information in the image is maintained.

Keywords: Image, Cryptography, Base64 Algorithm, Rijendel, AES
