The ViewAR cloud is hosted in Germany by “Hetzner”. Security information of “Hetzner”: https://www.hetzner.com/unternehmen/zertifizierung
The followind data is stored in the cloud by ViewAR:
- App configurations (which server is responsible for an app, licenses, tracking configuration,...)
- App styling (settings, images, colors, CSS)
- 3D model content (3D models, material settings, textures,...)
- AR tracking information (recognition patterns for indoor navigation, images or physical objects)
- Navigation maps (tracking references, 3D scan references, POIs, tours, content for POIs & tours, settings)
- Custom storage (Each app ID is able to store custom data (strings, files) via a key/value approach)
Data Handling – AR Navigation
AR Navigation Applications use 3D Pointclouds as their main input. Those 3D scans (pointclouds, 3D models and panorama images) are uploaded and used to generate a visual recognition pattern. Once the system has processed a scan, ViewAR saves a rudimentary 3D model of the scan including a texture and the visual recognition pattern. The visual recognition pattern can not be converted into a visual representation of the environment, it is basically just a list of contrast rich points and edges.
Data Handling – AR Product Visualization
For product visualization the ViewAR system uses 3D model uploads and converts them into a binary format. ViewAR saves the source files of uploaded 3D models for backup purposes. The apps only download the binary 3D models with textures and material descriptions. Theoretically it is possible to convert a binary 3D model into standard readable formats, but this requires expert knowledge.
Data Handling – Personal Data
ViewAR tries to avoid saving personal data of users. The standard procedure is to only use the ViewAR servers for non personal data and to use client’s servers for personal data.
