Abstract
Encryption of an image is achieved through application of a homomorphic encryption function to produce cipher images for each image. Encryption is performed individually on sub-values of a pixel's intensity value, wherein the pixel's intensity value can be described as a sum of the smaller numerical sub-values. The encrypted values for each sub-value form encrypted images that can be transferred or stored on insecure media. Separate encryption approaches can be applied to individual sets of the numerical sub-values to improve security.
