Methods for requesting and authenticating photographic image data
A system and method include obtaining and authenticating image files from users such as insured users at the request of an entity such as an insurance provider. The requesting entity may supply an electronic address of the user and a unique identifier. The system may transmit a link to the electronic address. When selected, the link causes an image authentication application to be installed on a user device. The application takes the images securely and separately from a native camera application. Each image authentication application may be customized for each requesting entity. The authentication server may identify the requesting entity that made the request and identify a corresponding image authentication application to be provided to the electronic address. The images from the image authentication application may be authenticated via reverse image search, time, geolocation, and/or other information. The authenticated images and/or related data may be provided to the requesting entity.

determining whether a location function of the user device is enabled; and
disabling image capture when the location function of the user device is not enabled.
10. The user device of claim 1 , the operations further comprising:
determining a characteristic of an available network connection; and
determining whether to transmit the electronic image over the available network connection based on the determined characteristic of the available network connection.
11. A non-transitory machine-readable storage medium encoded with instructions that, when executed by one or more hardware processors of a computing system, cause the computing system to perform operations for proving electronic images have not been tampered with via a decentralized ledger, the operations comprising:
generating an electronic image using an image authentication application executing on a user device;
generating a device-generated hash of the electronic image based on a hash function using the image authentication application executing on the user device;
generating an image identifier for the electronic image using the image authentication application executing on the user device, the image identifier comprising the device-generated hash;
initiating a blockchain transaction using the image authentication application executing on the user device, the blockchain transaction comprising the device-generated hash for incorporation into a block of the decentralized ledger;
obtaining a block identifier for the block from a blockchain network; and
storing, at a storage device accessible to the user device, the image identifier in association with the block identifier.
12. The non-transitory machine-readable storage medium of claim 11 , wherein:
the image authentication application executing on the user device generates the electronic image at a time; and
the block provides proof on the decentralized ledger of a state of the electronic image at the time the electronic image was generated.
13. The non-transitory machine-readable storage medium of claim 11 , the operations further comprising:
receiving a message comprising a link, the link representing a network location from which to download the image authentication application.
