This is a prototype implementation of HiPDS. The key idea of HiPDS is to leverage both the chameleon hash and the trusted execution environment (TEE) to plausibly hide the sensitive data in both the external storage and the internal memory. A salient advantage of HiPDS is that it can ensure deniability on any types of storage media, which is essentially important for users who may change the external storage devices over time. The source code of HiPDS is avaiable here (Please be aware that the source code is intended solely for research and study purposes, and comes with no warranty).
