Dass Micro­soft inten­siv an einer Per­so­nal Data Bank arbei­tet, war bekannt (Vgl. dazu: Pro­jekt “Bali” – Micro­soft arbei­tet an einer Per­so­nal Data Bank). Nun stellt Alex Simons von Micro­soft Azu­re in Iden­ti­ty Hubs as per­so­nal datas­to­res die, wenn man so will, Wei­ter­füh­rung der Idee vor.

Iden­ti­ty Hubs are decen­tra­li­zed, off-chain, per­so­nal datas­to­res that put con­trol over per­so­nal data in the hands of users. They allow users to store their sen­si­ti­ve data—identity infor­ma­ti­on, offi­cial docu­ments, app data, etc.—in a way that pre­vents anyo­ne from using their data without their expli­cit permission.

Users can use their Iden­ti­ty Hubs to secu­re­ly share their data with other peop­le, apps, and busi­nes­ses, pro­vi­ding access to the mini­mum amount of data necessa­ry, while retai­ning a record of its use.

Die per­so­nen­be­zo­ge­nen Daten wer­den dabei außer­halb der Block­chain oder Dis­tri­bu­t­ed Led­ger – Vari­an­te gespei­chert. Sie wer­den über Gerä­te und Clouds ver­teilt, so dass kein Sin­gle Point of Vul­nera­bi­li­ty ent­ste­hen kann:

A key pro­per­ty of the Hub is the abi­li­ty to sync and repli­ca­te across device(s) and Cloud(s). This means that users can run their Iden­ti­ty Hubs any­whe­re, with any pro­vi­der they choo­se, for instance on Micro­soft infra­st­ruc­tu­re or any­whe­re else. Such Iden­ti­ty Hubs can sync data across instan­ces to ensu­re the­re is no sin­gle point of vul­nera­bi­li­ty. None of the DIF com­pli­ant pro­vi­ders would have means to see who is sharing what data and with whom.

Durch die Unter­stüt­zung ver­schie­de­ner Stan­dards wird den App-Ent­wick­lern ihre Arbeit erleichtert:

App deve­lo­pers can leverage exis­ting indus­try-spe­ci­fic sche­mas, such as tho­se descri­bed at schema.orggs1.org, and hl7.org. If desi­red, any user or deve­lo­per can publish a cus­tom sche­ma that apps and ser­vices can use to col­la­bo­ra­tively store and access data. .. This open seman­tic data model ensu­res Hubs can act as gene­ric per­so­nal data stores that can flex to accom­mo­da­te a wide ran­ge of data and use cases—including per­so­nal info, app data, medi­cal records, etc.

Iden­ti­ty Hubs in der vor­lie­gen­den Form pas­sen womög­lich bes­ser zu den Anfor­de­run­gen der Nut­zer wie auch der neu­en Infra­struk­tu­ren (Block­chain, Dis­tri­bu­t­ed Led­ger, dezen­tra­le KI, Agen­ten­tech­no­lo­gie) als die eher her­kömm­li­chen Per­so­nal Data Stores wie Digi.me.
