Abstract—Open ban­king brings both the oppor­tu­ni­ties and chal­lenges to banks all over the world. Due to the dif­fe­rent eco­no­mic deve­lo­p­ment levels of each coun­try and the gaps among finan­cial envi­ron­ment matu­ri­ty, all count­ries have dif­fe­rent stra­te­gies and regu­la­ti­ons towards the pri­va­cy pro­tec­tion of data in finan­cial sce­nes, such as the Gene­ral Data Pro­tec­tion Regu­la­ti­on (GDPR) by Euro­pean Uni­on (EU). A block­chain as a con­ti­nuous­ly gro­wing list of records mana­ged by a peer-to-peer net­work is wide­ly used in various appli­ca­ti­on sce­na­ri­os, and can pro­tect the pri­va­cy of finan­cial data. Howe­ver, finan­cial block­chain still poses some pro­blems that can­not ful­ly meet the data pro­tec­tion needs. In order to address the exis­ting pro­blems, this paper pro­po­ses a new block­chain-based data pri­va­cy manage­ment frame­work. The frame­work con­sists of three com­pon­ents: a data pri­va­cy clas­si­fi­ca­ti­on method accor­ding to the cha­rac­te­ristics of finan­cial data and a new col­la­bo­ra­ti­ve-fil­te­ring-based model and a con­fir­ma­ti­on data dis­clo­sure sche­me for cus­to­mer stra­te­gies based on the Nudge Theo­ry. We imple­ment a pro­to­ty­pe and pro­po­se a set of algo­rith­ms for this manage­ment framework.
