Enkripsi Data Citra Untuk Model Warna Rgb Dan Treshold Menggunakan Algoritma Hill Cipher

Hill Chiper, RGB, Enkripsi Citr

With the increasingly widespread abuse of digital media, especially in the form of images or
images, it increasingly disrupts the rights and privacy of everyone. Many forms of abuse that
occur in digital media through internet facilities such as plagiarism of photographer's
work, recognition of the rights of the image, to upload photos of privacy to internet media.
Therefore, one way to secure digital data in the form of images is to randomize (encrypt) the
images that we feel are very important so that the image can no longer be interpreted by others.
If we need these data, we just need to return it (decryption) so that the encryption image can
return to its original form. Hill Cipher algorithm is one method to randomize a data by encoding
and multiplying the matrix. For its application in the form of image data, a trial is needed by
creating a software which will then analyze the results into several color models such as RGB,
Grayscale (Keabuan) and Tresholding (Black and White). From the test results, it can be
concluded that the greater the input matrix value of the Hill Cipher Algorithm, the more
encrypted image results will be obtained or in other words the more incomprehensible the visual
form by humans. Then the Hill Cipher algorithm cannot be applied to the color threshold model
(black and white) because the matrix multiplication obtained does not have a diverse range of
values.
