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: 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: 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.
