A data sharing system comprising a first data processing circuitry configured to store the user-specific data of a user. The data sharing system comprises at least one second data processing circuitry configured to store access rights of an external entity to access the user-specific data stored on the first data processing circuitry. The data sharing system comprises an interface between the first data processing circuitry and the second data processing circuitry configured to communicate the access rights from the second data processing circuitry to the first data processing circuitry. The data sharing system also comprises a user interface configured to authenticate the user to the second data processing circuitry for modifying access rights. Additionally, the data sharing system comprises an interface between the first data processing circuitry and the external entity configured to communicate a portion of the user-specific data to the external entity in accordance with the access rights.

Method, computer program and data sharing system for sharing user-specific data of a user

Embodiments of the present disclosure relate to a method. The method comprises, at a first user device, receiving user data from a tamper-proof second user device. Further, the method comprises, at the first user device, aggregating the user data according to a first logic and transmitting the aggregated user data and the user data to an external server. The method further comprises, at the external server, verifying whether the first logic, by which the aggregated user data and the user data are related to each other, corresponds to a predefined second logic for verifying a validity of the aggregated user data.

Privacy preserving verification of user data

A method comprising receiving, at a forum network node, a user request for posting a user message in an internet forum from a user network node. The user network node is associated with a digital identity of the user. The forum network node is associated with a digital identity of the internet forum. The forum network node has an interface to a distributed ledger. The user request indicates a parent post the user message relates to. The parent post is part of the internet forum. The method further comprises generating, at the forum network node, transaction data for the user message and a hash of the transaction data. The transaction data comprises a hash of the user message and a hash of the parent post. The method further comprises writing the hash of the transaction data and the transaction data on the distributed ledger.

Method and apparatus for posting a user message of a user in an internet forum

The present disclosure relates to a system for providing an electronic credential associated with electronic identification information of a user. The system comprises one or more electronic sensor devices configured to monitor an activity or a surrounding of the user and to generate user-specific sensor data, processing circuitry configured to analyze the user-specific sensor data to extract characteristic data associated with the user, and to generate a sensed electronic credential confirming the extracted characteristic data; and a memory configured to store the sensed electronic credential as part of the user's electronic identification information.

Method and system for providing an electronic credential associated with electronic identification information

A system comprising a distributed ledger (BC) configured to store a smart contract (SB) related to a problem statement (Z), the smart contract (SB) enabling a zero-knowledge proof (ZK) concerning the problem statement (Z).
