Motivation & Goal:
Nowadays 3D models are used in various applications such as computeraided design or scientific visualization. Furthermore, the vast majority of video games include 3D models as an essential component.
To ensure distinct identification or at least to prove the presence of a certain file within a huge set of data files, cryptographic hash algorithms are common use. However, even small modifications of the cover data render the cryptographic hash useless. This means, since in most practical scenarios 3D models have to be transferred and/or compressed and adjusted, cryptographic hashes cannot be used.
An alternative identifier e.g. for images is given by so called robust hashes or fingerprints. These are built to resist transmission and even strong modification or compression. However, in the field of 3D models, only few approaches exist, and no field test has been proceeded to prove practicability. Therefore, the goal of this thesis is to first analyze an existing state of the art hashing algorithm for 3D models in order to detect potential ways to optimize the approach. Afterwards these should be implemented and a significant testbed has to be carried out to state the results.
Tasks:
•Getting into the topic: Robust Hashes for Multimedia
•Analysis and Optimization of a robust 3D hashing algorithm
•Implementation and Evaluation of the algorithm
