Design of digital image application using vigenere cipher algorithm

This research focuses on engineering applications using digital image security vigenere cipher algorithm. vigenere cipher algorithm method is used for securing data in the form of digital images, especially for the logo of a company that is one of the methods of science of cryptography, in which the order logos or digital image that secure during transmission over the Internet. a method used to secure the data in the form of digital imagery to ascertain and assess whether the use of this method was successful or not. This research is presented to determine the safety of digital images, especially for a company logo using vigenere cipher algorithm through the application that created because so far we know only vigenere algorithm method used for the security of data in text form only. the final results of this study focuses on securing data in the form of a digital image for the company logo showed a significant result that the image of the once encrypted to be safe and successful, and decrypted to its original shape in accordance with the original digital image by using vigenere cipher.
