1. A system for encoding an input string of characters, comprising: a register for data structure definition including a starting empty cell; a register for a path definition defining a path through the data structure; a character reading and writing engine for writing a next character to an empty cell with a predefined initial position; a next cell determination engine for determining a next empty cell by checking cells along the path in the data structure until an empty cell is located; a loop facilitator for looping back to the writing next character step and the determining next empty cell step until there are no more data characters or a next empty cell is not determined; and a serialization deserialization engine for serializing the data structure into a string of characters representing an encoded string of alphanumeric characters.
