With Uproov - you can now prove any Image, Video, Audio or other file as authentic or not - and give it an unalterable time stamp - using Blockchain technology !

Take a picture and Uproov encrypts it instantly on your phone or Tablet and instantly sends the encryption key to the Blockchain where it is stamped in permanently.

If just one pixel or sound byte etc. is changed in the original file the Encryption key no longer matches! so you can prove if a picture is original - and exactly when it was taken.

You also have Copyright of all your images that you can now prove easily with this ground breaking World First technology.

No need to upload the files with Uproov when you create them - making it lightning fast and uses only small data transfer - ideal for when you are roaming !

Use it to prove the condition of anything or to time stamp a picture.

With the Uproov EasyID - which is stamped into the picture, you can also upload it to and have people see the original by simply entering the Easy Id.

We also use advanced watermarking technology, so you can use it for social media profile pictures ! people cant take a picture of your picture or you will see double watermarks, making it perfect for dating sites, Ebay, Facebook etc !
