Abstract: Methods and devices for privately verifying and enhancing location data by a distributed ledger system are disclosed. A location-based services server receives a possible location of a mobile device. A location verification system determines a detected location of the mobile device. A distributed ledger system uses a private set intersection technique to determine whether the possible location corresponds to the detected location without the possible location or detected location being shared. Probabilities associated with the possible and detected locations can also be combined to enhance the accuracy of the possible location.

Abstract: A method is provided for facilitating location-based digital transaction. The method may include scanning, using at least one sensor of a host device, a physical environment associated with a digital transaction location. The method may further include generating a set of host anchors based on the scanning of the physical environment. The method may further include computing a host anchor set geometry based on the set of host anchors. The method may further include determining an environment-embedded code associated with the computed host anchor set geometry and the digital transaction location. Further, the environment-embedded code may be stored. The stored environment-embedded code may be provided for facilitation of the digital transaction.

Abstract: A computer-implemented method can provide time-valid location-based information. The method comprises: for an environment, defining a plurality of cells, each cell comprising: a respective location with a range based on a geographical extent of the respective cell within the environment; a respective predetermined validity-time-interval; respective semantic-location-data relevant to the respective location; respective executable code instructions configured to operate on the respective semantic-location-data to enable determination of respective time-valid location-based information upon execution of the respective code instructions by a first edge computing apparatus proximal to the respective location. The respective time-valid location-based information is valid within the respective predetermined validity-time-interval.

Abstract: An approach is provided for a consent management using a cryptographic ledger (e.g., a blockchain). The approach, for example, involves providing a cryptographic ledger. The cryptographic ledger includes one or more data records that store metadata indicating a consent request from a data consumer to provide an access to data owned by a data subject, a consent response from the data subject to the consent request, or a combination thereof. The approach also comprises providing a neutral server to read the data from a database of a data provider on behalf of the data consumer based on the cryptographic ledger.
