You can verify a SeeHow-watermarked picture by entering the image ID in the search bar above. This will return the blockchain-secured orginal image along with its metadata, i.e. location (GPS coordinates), accuracy (in metres), time, date and description.

SeeHow is an app used by manufacturers to take pictures from their work along the supply chain and store them on the blockchain making the action immutable. SeeHow hashes and saves the images, their time, date and location on the blockchain and protects them from manipulation. As a result, you know that what you see on SeeHow-watermarked pictures is real.

Sorry this is no original SeeHow image.

Did you type in your ID correctly?

Did you mind capital letters and numbers (e.g. Os and 0s)

The image ID is a unique identification number. It was generated when encrypting the image on the blockchain.

The image hash is the SHA-256 of the original, unmanipulated image, which was added to the blockchain. If someone changed the image in some sort (e.g. filter), you can hash it and comapare the hashes which would now be different. Hash your image here.

The transaction hash shows that the image along with its metadata was successfully added to the SeeHow blockchain.
