Abstract

Image encryption is a technique to protect the confidentiality of images from illegal access. With image encryption, people who do not know how the image is hidden will not know how to open it. Encryption is needed because in today's digital era digital images are easily stored or transmitted through public channels such as the internet. Image transmission through public channels is prone to tapping and storing images in storage media prone to access by parties without authority. For this reason, it is necessary to do a cryptographic method to secure confidential images from parties who do not have the authority to understand the actual image. This study presents an image encryption algorithm using Pohlig Hellman's Algorithm. The Pohlig Hellman algorithm is an algorithm used to compute discrete logarithms in a multiplicative group whose rank is not a safe prime number.Cryptography, Image, Pohlig-Hellman

Abstract

Infectious diseases known as infectious diseases are a disease caused by a biological agent (such as viruses, bacteria or parasites), which can be transmitted or transmitted to others through certain media such as air, food and drink that are less clean , syringes and blood transfusions and direct contact with the patient. The expert system is one of the branches of Artificial Intelligence that makes extensive use of knowledge, especially for the expert-level problem-solving. Bayes is a simple probabilistic based prediction technique based on bayes rules. The goal to be achieved is to create a useful expert system application as a tool to get information on infectious diseases in infants. Keyword: Infectious Diseases, Expert Systems, Bayes, Infant
