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 subvalues of a pixels intensity value, wherein the pixels 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.

Abstract: Systems, methods and apparatus for secure encryption and decryption of a file may be provided which may include generating, by a first processor, a plurality of encryption isokeys, wherein the plurality of encryption isokeys include a first public isokey, a second public isokey, and a private isounit; and encrypting, by the first processor, ciphertext associated with a message based on the plurality of encryption isokeys. The approach may also include receiving, by a second processor, the ciphertext associated with the message; generating, by the second processor, a plurality of decryption isokeys, wherein the plurality of decryption isokeys include the private isounit, a private decryption isokey, and the first public isokey; and decrypting, by the second processor, the message associated with the ciphertext based on the plurality of decryption isokeys.
