The paper investigates the security of a selective coordinate encryption scheme for point clouds used in volumetric video. By training PointNet and Random Forest models on partially encrypted data, the authors show that fully encrypting all X coordinates is difficult to reconstruct, whereas encrypting every second X coordinate allows accurate recovery of the hidden values. The study highlights that the encryption granularity critically determines the vulnerability of the scheme.

ResStreamGS introduces a residual‑sensitive dual‑stream framework for mobile volumetric video streaming that distinguishes temporally stable Gaussians from residual‑sensitive ones. Stable Gaussians are transmitted once per Group of Pictures, while only the residual‑sensitive Gaussians are included in the frame‑wise video stream, reducing bandwidth usage. Experiments on complex full‑scene videos show a 7.51–8.35 dB PSNR improvement over a V³‑style baseline, a payload reduction of up to 56.5%, and real‑time performance of 30.883 FPS on a Qualcomm Snapdragon 778G.
