Abstract
This disclosure describes techniques to authenticate that a media content item such as a photograph, a video, etc. is attributed to and originated by a particular user, based on the device on which the content was created. The content item is created on a device and associated with a digital signature using an attestation mechanism of the device such as trusted hardware or a sensor pattern that is unique to the device. The digital signature and content item are provided to a register or service for access by other users. When an accessing user views the content item, the content item is verified, via the digital signature, as having originated from the originating user’s device. The accessing user’s device displays the status of user attribution of the content item, indicating that the content item originates from a legitimate user and has not been forged, modified, or stolen. Described techniques are privacy-preserving and do not disclose the identity of the originating user.
