Abstract: Methods and systems are used for providing a traveling avatar in a smart feedback system (SFS). As an example, a user associated with a first interaction with the SFS from a first device at a first location is identified. A first visualization of a personalized avatar associated with the user is provided to the first device. A first personalized feedback request is provided to the first device during the first visualization. First feedback of the user captured by the first device is received in response to the first personalized feedback request. The user associated with a second interaction with the SFS from a second device at the first location is identified. A second visualization of the personalized avatar is provided to the second device. A second personalized feedback request is provided to the second device. Second feedback of the user captured by the second device is received.

Abstract: Systems and methods include reception of a request to validate the identity of a first entity associated with a decentralized identifier, validation of the identity of the first entity based on the decentralized identifier and on a verifiable data registry, requesting, in response to validation of the first entity, first consent from a first user to provide data associated with the user to the first entity, reception of the first consent from the first user; and, in response to receipt of the first consent, store an indication of the first entity, the first user and the first consent in a first data store associated with the first user, and provide the data associated with the user from the first data store to the first entity.

Abstract: Systems and methods include reception of a first user interface from a data requestor, display of the first user interface on a display, launch of an application to provide the requested data, display of a second user interface of the application overlaid on the first user interface, reception of identifiers of shareable data from a data provider and display of the identifiers in the second user interface, reception of an indication, via the second user interface, of a set of the shareable data to share with the data requestor, transmission of an authorization to the data provider to store the set of shareable data in a data storage, and transmission of a second authorization to the data storage to share the set of shareable data with the data requestor.

Abstract: The disclosure relates to a computed-implemented method, a computer program, and a computer system for selectively verifying personal data. The method comprises receiving, by an identity application of a client device, personal data of a user. The method further comprises computing, via a cryptographic hash function, one or more cryptographic hashes from elements of the personal data. The method further comprises storing the cryptographic hashes, an internal identifier and a timestamp as an entry in a distributed database. The internal identifier is unique within the distributed database. The method further comprises receiving a user request from the user. The method further comprises selecting one or more of the elements of personal data for verification. The method further comprises requesting verification of the selected elements of personal data. The method further comprises determining an authorization indication in response to the verification request.

Abstract: Methods and systems are used for providing user and multi-user smart feedback in a smart feedback system (SFS). As an example, a first personalized feedback request is provided to a first device during a first visualization of a first personalized avatar associated with a first user. First feedback of the first user captured by the first device is received. The first feedback is analyzed based on a first user profile and the first personalized feedback request associated with a first offer associated with a first participant. A first recommendation is determined based on the first user profile, the analyzed first feedback of the first user, the first offer associated with the first participant, and a second user profile of an associated second user. The first recommendation is provided to the first device during the first visualization of the first personalized avatar associated with the first user.

Abstract: A computer-implemented method is provided for secure data sharing. The method comprises: storing, by a data owner or an entity authorized by the data owner, via a data management user interface, in a decentralized data storage, data in an encrypted format; storing, via the data management user interface, in a blockchain, information indicating the data owner and a reference to the data stored in the decentralized data storage; and storing, by the data owner, via the data management user interface, in the blockchain, information indicating consent given to one or more authorized users for using the data.
