Implementation of a histogram-based watermarking method, which is commutative to a permutation cipher in the time domain. Furtheron a minimum knowledge verification in form of a probabillistic protocol, which is based on the graph isomorphism problem, is implemented. A detailed description can be found in the following journal article of Prof. Dr. R. Schmitz and myself: https://www.hindawi.com/journals/am/2017/5879257/abs/

The Python code follows the PEP8 styleguide and the recommendations of this site: https://gist.github.com/sloria/7001839

./audio-cwe-framework

• core - contains the classes and modules, which implement the watermarking schemes and the asym verification protocol
• experimental_testing - contains code, that was used to generate the experimental results
• notebooks - contains IPython notebooks (which can be run in a browser e.g.), that were used in the course of exploration activities, demonstrate the usage of the classes and modules in core or show certain other features
• plotting - contains code, which was used to plot the figures of the associated thesis

./res should contain soundfiles(marked and/or unmarked)

• demo - results of marking processes
• testing - files for evaluation
