Encrypted biometric encoded security documents

A user permissions communication interface system comprising a scanner, a identifying characteristic reader, a computer, a comparator, a connection means, and a disposition device,

• wherein the connection means operably connects the computer to the scanner, the reader and disposition device,
• wherein the scanner reads a portable identification carrier on which is encoded machine-readable, digital identifying characteristic data of at least one person, the data being represented as X-nary data in a 2-D matrix, wherein the X-nary data is represented by an X-nary bit comprising a line wherein a characteristic angular displacement from a reference determines the value of the X-nary bit wherein further the computer has:
• (a) transmission means to transmit such scanned identifying characteristic data from the scanner to the computer for verification of the authenticity of the carrier, and
• (b) logical extraction means to extract an identifying characteristic of a certain identifying characteristic parameter from the identifying characteristic data encoded on the carrier,
• wherein the identifying characteristic reader is adapted to read a same identifying characteristic parameter of the at least one person purported to be identified by the carrier,
• wherein the comparator compares the encoded identifying characteristic with the extracted identifying characteristic to authenticate the at least one person associated with the carrier;
• wherein the connection means, if the carrier and at least one person are authenticated, enables the computer to connect to a data storage device of permissions associated with that person or type of person;
• and
• wherein the disposition device dispositions the at least one person in a prescribed manner.

A method of increasing the data storage capacity of a printed data storage device, the method comprising the steps of:

• a. optionally encrypting data to be stored;
• b. encoding such data into a superimposable, differentiable information layer, each layer of information being differentiated from other such layers through a specific characteristic in its representation, the differentiation permitting separation of the layers during a decoding process;
• c. superposing each differentiable layers of encoded data;
• and
• d. printing the superimposed layers on a printable substrate.
