Abstract: In one implementation, a device provides, to a user interface, proof-of-creation information that certifies that data presented by the user interface was created by one or more sensors capturing the data from a real person. The device receives, via the user interface, an edit to the data, to form edited data. The device associates one or more keys with the edited data that are based on the proof-of-creation information and on the edit to the data. The device provides, based on the one or more keys, lineage information to the user interface in conjunction with the edited data that indicates the edit to the data and the proof-of-creation information.

Abstract: In one embodiment, a verifying device may: receive a certificate of a remote entity over a computer network; extract, from within the certificate, a storage location of a digital identity of the remote entity; obtain the digital identity from the storage location; and accept the certificate of the remote entity in response to both the certificate and the digital identity being verified by the verifying device.

Abstract: In one embodiment, a device identifies, for an existing digital identifier, a public key, a sequence number, and a signature. The device forms a new digital identifier that includes the public key, the sequence number, and the signature identified by the device for the existing digital identifier. The device signs the new digital identifier with a new signature using a private key. The device uses the new digital identifier to prove legitimacy of data associated with the new digital identifier.

Abstract: In one embodiment, a data sharing platform uses data associated with a data owner to share data via a plurality of sharing services, each sharing service in the plurality of sharing services providing a different type of data. The data sharing platform tracks access to each of the plurality of sharing services. The data sharing platform computes, based in part on the access to each of the plurality of sharing services, an importance metric for the data associated with the data owner. The data sharing platform provides an indication of the importance metric for display to the data owner.
