Abstract
An image encryption/decryption system performs quantification and reconstruction of 2-D and 3-D layered and arbitrary grayscale or binary images in raster or vector format and supports their secure transmission between a Sender and a Receiver. Quantification parameters of the images include Indices of Intrinsic Anisotropy of size (IIAsize) and structure (IIAstr), which reflect the image anisotropy with high sensitivity. The IIASTR and IIASIZE are used as hash values in authentication of a transmitted image. The system assures that the same set of transects which was used by the Sender in the image encryption will be used only by an authorized Receiver for decryption of the image. Using the Quantification parameters (IIAstr and IIAsize), the present technique pinpoints the differences in structure and size in time series images, computes the localization of the differences between images of different categories and presented in different formats, and is capable of performing reconstruction of original 2-D and 3-D images from their N-partite graphs G (N) and F(M,N) table. The subject system and method may be used for fully automated quantification of dimensions and structure of 2-D a…
