Chryptography or Chriptology plays an important role in building data and information security. Chryptography aims to not read unauthorized people, so information can be safely maintained. Some research about Chryptography and algorithms related to data security have been done by practitioner of informatics and mathematic, one of which is DES algorithms and wavelet transform. DES algorithm is symmetrical standart algorithm which is widely used and is still considered safe to answer th challenges of the rapid development of information technology.This paper have discussed about application of Algebra in DES algorithms and discrete Wavelet Transform On Digital Image Security Application, i.e. XOR operation, permutation, and  permutation group or siklik group which is used in DES algorithms on digital image security application. Then, as Group it found (x+b)-group  in discrete wavelet transform on digital image security application

The image is a function of 2 (two) dimensions f (x, y), where x and y are the coordinates that show the space, and the value of f (x, y) is called the image intensity at the coordinates. Digital image is an image that has a limited value of x, y, f (x, y). Digital images consist of a limited number of elements, where each element has coordinates and values. These elements are called pixels (Gonzalez and Woods., 2007). One method of randomization in the image is Arnold Transformation where the image is transformed using a cat map, which is a 2x2 matrix. After transformation, the value of each pixel gets new coordinates until the image does not have its original shape. As a result of the above problems, the author uses the basis of Arnold Transformation, to change the value of the map paint with Fibonacci and Lucas series for designing this application so that the randomization results have a higher level of security. The purpose of this study is (1) to do digital image randomization using Fibonacci and Lucas transforms so that the image does not have its original shape anymore and (2) save the randomized images into storage memory. The benefits of this study are (1) the design of digital image randomization applications, so that image security increases and (2) the effectiveness of the Fibonacci and lucas transformation methods in digital image randomization.Keywords: Image Processing, Fibonacci and Lucas
