in a blog from Monday has divided Alex Simons, Director of program management at Microsoft, his vision of the future for decentralized digital identities. The Blockchain will help to regain control of their own data.
Microsoft wants to contact a for digital identities, which should ensure more privacy and safety, but put the control in the hands of identity bearers. Simons according to the Blockchain technology is suitable to allow distributed IDs (DID). Therefore ideas for the use of the Blockchain and other distributed ledger technologies were developed in the last 12 months. The product manager of the identity Division of Microsoft, Ankur Patel, has presented the results and the resulting principles.
Data processing today tomorrow
Patel vs. digital identity sees a need for a digital identity in the modern way of life in the digital and physical reality fuse together. This should increase the security as well as privacy in both realities. Just those who live even without proof of identity, to benefit from the freedoms, can bring to a digital card with. This includes also the control over their own data. Currently, these are distributed with the consent to data use for apps and other services to many providers. By the users agree that their data collected, used and stored, they will lose control, what happens exactly with their data. Again and again make it headlines about data breaches and identity theft on the front pages of the newspapers. This can be prevented by means of an encrypted digital hub (in German as “hub”). Users should save their identity data and control access:
“each of us needs a digital identity that we have, that all elements of our digital identity stores securely and privately. This identity must be easy to use and give us full control over the access and the use of our identity data.”
Microsoft Microsoft’s guidelines for the development of DIDs
for the development of a decentralized identity (DID) has drafted guidelines which explain how to deal with our data. Most importantly they show what must be changed as to digitize and decentralize identity data.
“today apps, services, and organizations offer comfortable, predictable and tailor-made experiences, that depend on identity-bound data control. “We need a secure, encrypted digital hub (ID hubs), which interact with the user’s data and can at the same time preserve the privacy and control of the user’s ‘,
Conventional identity systems are especially geared to the authentication and access management. To decentralize the data, authentication certificates ought to be manufactured. These certificates are claims that are confirmed by other entities and thus demonstrate aspects of identity. So will prevent transmitting a flood of data and only revealed what is really relevant. Just apps that offer features that are tailored to their users, will receive only those data that the user would like to pass on. Patel stressed that a robust decentralized identity system that is accessible to all, only through open-source solutions to achieve. Therefore Microsoft cut a year ago to the decentralized identity Foundation (DIF) . At the same time, the participating organizations develop together decentralized identifiers (DIDs). Specifically, it is a W3C specification that defines a common document format to describe the State of a distributed identifier. The DIF is also working on identity hubs and a server that is intended to replace the DIDs on Blockchains across. Continue to login credentials can be verified about a W3C specification, by defining a document format for the encoding of DID-based accreditations.
A step the Microsoft authenticator app can be used today to the other
to prove his identity. As a next step, Microsoft wants to experiment with decentralized identities. To do this, they will be integrated into the app. The user can then decide whether he wants to use the Microsoft authenticator as a user agent to manage identity data and cryptographic keys. It anchored but only the ID in the Blockchain, the identity data is meanwhile in a non-displayed for Microsoft hub outside the Blockchain and are encoded with cryptographic keys. If however everything working the way Microsoft imagines that cannot be verified in theory. Therefore, Patel now asks users for help and feedback.
