In this paper, we present a novel technique for secure distributed storage and dissemination of digital images using Chinese remainder theorem (CRT). The proposed technique not only involves significantly low computational complexity but also imposes various stages of difficulty to an intruder who intends to extract the original image from the encrypted sub-blocks. The proposed CRT-based technique is, therefore, useful for secure archival of large volume of image data and sharing of digital images by the users from different locations
