Future Internet is a scholarly, peer-reviewed, open-access journal on Internet technologies and information society. Every month Future Internet is published online by MDPI.  On Nov. 28, 2022.  “SAUSA: Securing Access, Usage, and Storage of 3D Point Cloud Data by a Blockchain-Based Authentication Network” has been published and featured in Future Internet as part of the Special Issue Security and Privacy in Blockchains and the IoT II and is available online at the link below.

l (3D) acquisition technologies, 3D sensors are increasingly available and affordable, such as light detection and ranging (LIDAR) sensors, stereo cameras, and 3D scanners. Complemented with two-dimensional (2D) images, 3D data acquired by sensors demonstrate rich geometric, shape, and scale information such that they provide an opportunity for a better understanding of surrounding environments for machines [1]. In general, 3D data can be represented with different formats, such as depth images, point clouds, meshes, and volumetric grids. When compared to other 3D data formats, 3D point cloud representation preserves the original geometric information along with associate attributes in a 3D space without any discretization…
