Abstract: Embodiments of reversible systems and methods for fast, secure and efficient transmission, storage, and protection of digital multimedia are disclosed. The embodiments may have the ability to simultaneously compress and encrypt digital data in order to concurrently reduce data size and prevent reconstruction without the proper encryption key. Embodiments of a method may include pre-processing data to optimize the size of data segments to be compressed, transforming the data for improving the compressibility of the before-mentioned data segments, processing the data sequentially to generate predictive statistical models, encoding the data for simultaneously encrypting and compressing data segments using a keystream, and increasing both the compression ratio and security of these encoding processes using a block cipher. Embodiments of these methods may be suitable for use on both encrypted and unencrypted media.

Abstract: Adaptive methods and apparatuses include compressing, recompressing, decompressing, and transmitting/storing digitized media data, such as text, audio, image, and video. Methods may include partitioning data; transforming partitioned data; analyzing partitioned data; organizing partitioned data, predicting partitioned data; partially or fully encoding partitioned data partially or fully decoding partitioned data, and partially or fully restructuring the original data.
