Latest Patents

One of Dana's latest patents is a data compression and encryption algorithm. This method involves a compression scheme that incorporates encryption. It begins by receiving input data comprising multiple data elements. A Huffman tree coding representation of the input data is constructed based on a known encryption key. The Huffman tree consists of nodes that represent compression codes, with lengths corresponding to the occurrence probabilities of the data elements. The encryption key specifies a subset of nodes selected for the encryption process. The method includes applying a specified transformation to each sub-tree of the Huffman tree rooted at one of the selected nodes, ultimately generating an output data file based on this application.

Another notable patent is related to systems and methods of data compression. This computer-implemented method compresses a baseline dataset that includes a sequence of multiple instances of unique data elements. It provides a weight function that calculates an increasing value for each instance based on previously processed sequential locations. The method computes an encoding for the baseline dataset according to the distribution of the weight function and creates a compressed dataset based on this encoding.
