A system for encrypting two-dimensional data such as image data, or data like multi-media data which can be transformed into two-dimensional data. The data is encrypted by multiple encryption passes through the data. In each pass, each mth row and each nth column of data is encrypted by complementation of the data in the row or column. For each encryption pass, m and n are randomly selected. The encryption system converts non-two-dimensional data to a pseudo-two-dimensional format by computing the square root of the binary length of the non-two-dimensional data file. |
