The H2020 project WITDOM (empoWering prIvacy and securiTy in non-trusteD envirOnMents) has entered its third and final year, ending in December 2017. The project faces a very exciting period ahead, as its main result, the WITDOM end-to-end security and privacy framework for outsourced data, will be finally instantiated in the two exemplary scenarios for its validation: the financial services scenario and the genomic scenario.
The WITDOM framework is based on a flexible end-to-end secure architecture for untrusted environments (particularly the public cloud), which was one of the major outcomes of the second project year. It also relies on the WITDOM platform, which orchestrates a variety of complex processes to protect sensitive data in a trusted domain in order to enable secure and privacy-preserving further processing, storage, and sharing of protected data in an untrusted environment.
To this end, WITDOM offers a wide set of protection functionalities through a rich set of protection components, some of them contributing significantly to advance the state of the art in the following domains:
- homomorphic encryption
- secure processing in the encrypted domain
- privacy-enhancing techniques, and
- verifiability techniques.
The WITDOM protection components provide the following functions:
- Secure signal processing,
- Secure computation,
- Integrity and consistency verification,
- Data masking and desensitisation,
- End-to-end encryption (E2EE).
Preliminary versions of both platform and protection components were released at the end of December 2016 and they are nowadays under a full integration and deployment process, expected to end in July 2017.
