3-D prosthetic or object model file secure encapsulation in a non-distributable image rendering file format

A system for displaying a digital data file containing a 3-dimensional representation of an object comprising:

• a computer processor specifically adapted to:
• receive an encrypted converted digital data file having a file format, wherein the encrypted converted digital data file is generated from the digital data file which has been initially converted to a converted digital data by modifying the digital data file based on a seed string, and then subsequently encrypting the converted digital data using an encryption algorithm and encoding key to create the encrypted converted digital data file;
• and
• making available the encrypted converted digital data file in the file format to a software environment, wherein the software environment in operation is suitable for decrypting the encrypted converted digital data and generating from the converted digital data file a temporary digital data file resident only in volatile memory within the operating software environment;
• and
• an image-generating arrangement to process the temporary digital data file and display the object integrated with other objects solely within the operating software environment, wherein the object is visible to the user of the operating software environment and the user cannot create a digital equivalent of the 3-dimensional representation of the object in any physical or virtual form external to the operating software environment.
