UDPP: Blockchain based Open Platform as a Privacy Enabler

Data privacy has drawn a lot of attention from people in sectors of commerce, data processing and credit reporting, especially with the adoption of GDPR, CCPA, PIPA, GB/T35273 and ISO27701 etc. These regulations aim to give people the ownership of data they produce by law, however, due to the lack of standards, tools, and best practices, many enterprises struggle to adapt their workflow and database to ensure that the data processing is in compliance with the data owner's consent and suffer from heavy fines. In light of this challenge, we develop a blockchain based platform to enable both privacy preserving and privacy compliance. UDPP (User Data Privacy Protection) platform is constructed on an immutable blockchain system, including the compliance module and the privacy tool set. UDDP provides utilities and tools to make desensitization, encryption and self-check process easier. The compliance module can assist companies to self-check on the privacy policy as well as the data processing both in their apps and backend services, while the tool set provides multiple combinations of privacy protection schemes to solve different privacy preserving and user authorization cases. Moreover, UDPP will provide the user with a “token”, which represents the permissions of the data ownership. The token can be viewed as a privacy badge, and it records hash of all the data processing and storage infos as well as the update of user consents.
