Abstract—With the increasing popularity of 3D objects in
industry and everyday life, 3D object security has become
essential. While there exists methods for 3D selective encryption,
where a clear 3D object is encrypted so that the result has the
desired level of visual security, to our knowledge, no method
exists for decrypting encrypted 3D objects hierarchically. In this
paper, we are the first to propose propose a method which allows
us to hierarchically decrypt an encrypted 3D object according
to a generated ring of keys. This ring consists of a set of keys
that allow a stronger or weaker decryption of the encrypted 3D
object. Each hierarchically decrypted 3D object has a different
visual security level, where the 3D object is more or less visually
accessible. Based on a master key, these hierarchical keys are
generated using our method during the encryption process. Our
method is essential when it comes to preventing trade secrets from
being leaked from within a company or by exterior attackers.
It is also ecologically friendly and more secure than traditional
selective encryption methods.
