Abstract
A device is provided for encrypting and/or decrypting a point cloud having a plurality of data points that collectively produce a three-dimensional (“3D”) image. Each data point may have a set of elements with values that define a position of the data point in 3D space and visual characteristics of the data point. Encrypting the point cloud may include deterministically a set of data point to encrypt, and deterministically changing the data point element values of the selected data points so that the 3D image produced by the encrypted data points is different than the 3D produced from the unencrypted data points. Decrypting the resulting encrypted point cloud may include deterministically reselecting the encrypted data points using an encryption key, and deterministically reversing the changes made to the data point element values of the selected data points based on transformations that are specified as part of the encryption key.
