Abstract
Methods and apparatuses are presented for securely providing digital streaming data to subscriber devices using encrypted wavelet meshes. A recorded image may be subdivided into three sources of data: light sources, camera angles, and the objects themselves. Each of these sources of data may be considered unique from each other, and the totality of the three sources of data may comprise a complete image. Without one of the sources of data, the image may not be complete. Each of the three sources of data may therefore be characterized as key spaces, wherein encrypting part of or the entirety of even one of these key spaces prevents the complete image from being viewed. Methods and apparatuses are provided for utilizing the concept of encrypting at least a portion of at least one of the three key spaces in order to securely and/or privately transmit image data to subscribers.
