Some rendering tasks, however, require the highest level of confidentiality so that no other party, besides the owner, can read or see the sensitive data. Here we present a direct volume rendering approach that performs volume rendering directly on encrypted volume data by using the homomorphic Paillier encryption algorithm. This approach ensures that the volume data by using the homomorphic Paillier encryption algorithm. This approach ensures that the volume data and rendered image are uninterpretable to the rendering server. Our volume rendering pipeline introduces novel approaches for encrypted-data compositing, interpolation, and opacity modulation, as well as simple transfer function design, where each of these routines maintains the highest level of privacy. We present performance and memory overhead analysis that is associated with our privacy-preserving scheme. Our approach is open and secure by design, as opposed to secure through obscurity. Owners of the data only have to keep their secure key confidential to guarantee the privacy of their volume data and the rendered images. Our work is, to our knowledge, the first privacy-preserving remote volume-rendering approach that does not require that any server involved be trustworthy; even in cases when the server is compromised, no sensitive data will be leaked to a foreign party.", "authors_et_al": false, "substitute": null, "main_image": { "description": null, "filetitle": "image", "main_file": true, "use_in_gallery": true, "access": "public", "image_width": 1871, "image_height": 757, "name": "Mazza_2020-image.JPG", "type": "image/jpeg", "size": 151232, "path": "Publication:Mazza_2020", "url": "https://www.cg.tuwien.ac.at/research/publications/2020/Mazza_2020/Mazza_2020-image.JPG", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2020/Mazza_2020/Mazza_2020-image:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 1035, 616, 171 ], "cfp": { "name": "Papers - IEEE VIS 2020.pdf", "type": "application/pdf", "error": "0", "size": "954206", "orig_name": "Papers - IEEE VIS 2020.pdf", "ext": "pdf" }, "date_from": "2020-01-10", "date_to": "2020-10-13", "doi": "10.1109/TVCG.2020.3030436", "event": "IEEE VIS (SciVis) 2020 conference", "first_published": "2020-10-13", "journal": "IEEE Transactions on Visualization andComputer Graphics", "lecturer": [ 1035 ], "open_access": "yes", "pages_from": "1", "pages_to": "10", "volume": "27", "research_areas": [ "MedVis" ], "keywords": [ "Volume Rendering, Transfer Function, Homomorphic-Encryption, Paillier" ], "weblinks": [], "files": [ { "description": null, "filetitle": "image", "main_file": true, "use_in_gallery": true, "access": "public", "image_width": 1871, "image_height": 757, "name": "Mazza_2020-image.JPG", "type": "image/jpeg", "size": 151232, "path": "Publication:Mazza_2020", "url": "https://www.cg.tuwien.ac.at/research/publications/2020/Mazza_2020/Mazza_2020-image.JPG", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2020/Mazza_2020/Mazza_2020-image:thumb{{size}}.png" }, { "description": null, "filetitle": "Paper", "main_file": true, "use_in_gallery": true, "access": "public", "name": "Mazza_2020-Paper.pdf", "type": "application/pdf", "size": 1728814, "path": "Publication:Mazza_2020", "url": "https://www.cg.tuwien.ac.at/research/publications/2020/Mazza_2020/Mazza_2020-Paper.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2020/Mazza_2020/Mazza_2020-Paper:thumb{{size}}.png" } ], "projects_workgroups": [ "vis" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2020/Mazza_2020/", "__class": "Publication" }, { "id": "Viola_Ivan_2013_GS", "type_id": "journalpaper_notalk", "tu_id": null, "repositum_id": null, "title": "Geological storytelling", "date": "2013-08", "abstract": "Developing structural geological models from exploratory subsea imaging is difficult and an ill-posed process. The structural geological processes that take place in the subsurface are both complex and time-dependent. We present Geological Storytelling, a novel graphical system for performing rapid and expressive geomodeling. Geologists can convey geological stories that externalize both their model and the reasoning process behind it through our simple, yet expressive sketch-based, flip-over canvases. This rapid modeling interface makes it easy to construct a large variety of geological stories, and our story tree concept facilitates easy management and the exploration of these alternatives. The stories are then animated and the geologists can examine and compare them to identify the most plausible models. Finally, the geological stories can be presented as illustrative animations of automatically synthesized 3D models, which efficiently communicate the complex geological evolution to non-experts and decision makers. Geological storytelling provides a complete pipeline from the ideas and knowledge in the mind of the geologist, through externalized artifacts specialized for discussion and knowledge dissemination among peer-experts, to automatically rendered illustrative 3D animations for communication to lay audience. We have developed geological storytelling in collaboration with domain experts that work with the modeling challenges on a daily basis. For evaluation, we have developed a geological storytelling prototype and presented it to experts and academics from the geosciences. In their feedback, they acknowledge that the rapid and expressive sketching of stories can make them explore more alternatives and that the 3D illustrative animations assist in communicating their models.", "authors_et_al": false, "substitute": null, "main_image": { "description": "", "filetitle": "", "main_file": false, "use_in_gallery": false, "access": "public", "image_width": 500, "image_height": 435, "name": "Viola_Ivan_2013_GS-.jpg", "type": "image/jpeg", "size": 53391, "path": "Publication:Viola_Ivan_2013_GS", "url": "https://www.cg.tuwien.ac.at/research/publications/2013/Viola_Ivan_2013_GS/Viola_Ivan_2013_GS-.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2013/Viola_Ivan_2013_GS/Viola_Ivan_2013_GS-:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 1150, 1151, 616, 176, 171 ], "issn": "0097-8493", "journal": "Computer & Graphics", "number": "5", "pages_from": "445", "pages_to": "459", "volume": "37", "research_areas": [], "keywords": [], "weblinks": [ { "href": "http://dx.doi.org/10.1016/j.cag.2013.01.010", "caption": null, "description": null, "main_file": 0 } ], "files": [ { "description": "", "filetitle": "", "main_file": false, "use_in_gallery": false, "access": "public", "image_width": 500, "image_height": 435, "name": "Viola_Ivan_2013_GS-.jpg", "type": "image/jpeg", "size": 53391, "path": "Publication:Viola_Ivan_2013_GS", "url": "https://www.cg.tuwien.ac.at/research/publications/2013/Viola_Ivan_2013_GS/Viola_Ivan_2013_GS-.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2013/Viola_Ivan_2013_GS/Viola_Ivan_2013_GS-:thumb{{size}}.png" } ], "projects_workgroups": [ "illvisation" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2013/Viola_Ivan_2013_GS/", "__class": "Publication" }, { "id": "Viola_Ivan_2013_RSb", "type_id": "inproceedings", "tu_id": null, "repositum_id": null, "title": "Rapid Sketch-based 3D Modeling of Geology", "date": "2013-06", "abstract": "We present and compare two different approaches for performing rapid 3D geological modeling.

While research has\r\nscrutinized the possible uses of one and multi-dimensional transfer functions in the spatial domain, to our\r\nknowledge, no attempt has been done to explore transfer functions in the frequency domain. In this work we\r\npropose transfer functions for the purpose of frequency analysis and visualization of 3D data. Frequency-based\r\ntransfer functions offer the possibility to discriminate signals, composed from different frequencies, to analyze\r\nproblems related to signal processing, and to help understanding the link between the modulation of specific\r\nfrequencies and their impact on the spatial domain. We demonstrate the strength of frequency-based transfer\r\nfunctions by applying them to medical CT, ultrasound and MRI data, physics data as well as synthetic seismic\r\ndata.
