Blockchain-Powered Notary Service Uproov To Roll Out Its Android App This Week

Uproov, which allows users to instantly prove any photos, videos or sound recordings, launched on the iTunes App Store last month, and will be available on Android by 15 January, reported IBTimes UK. It is developed by LedgerAssets Pty Ltd which has vast experience in blockchain and cryptographic technology. It aims to improve the way digital and physical content is owned, traded and verified by relying on the public Blockchain Ledger.

Data on recordings taken with Uproov are stamped into the Blockchain Ledger, which removes any doubt about users’ images – it time stamps to the nearest second and cannot be edited – Uproov can detect minutest changes, if made.

"Uproov uses dynamic client side encryption and the Blockchain protocol to secure data packets into the Blockchain, reflecting the genuine image, audio or video data”, John Bulich, co-founder of Ledger Assets, told IBTimes. "This means those submitted images cannot be altered, not even by one pixel, nor can any part of the file, image, video or audio be removed. Alteration of any of those aspects will cause the encryption key to no longer match what was entered into the Blockchain.”

Uproov can be used to record live Video, Photos, Audio and pre-existing files. For pre-existing files, v2.0 and above allows any file from Dropbox, iCloud or other major cloud service provider to be accessed and Uproov'ed, IBTimes reported.

Speaking to AllCoinsNews, Bulich explained that Uproov stamps an “Ezy-Id” on the bottom of the photo so others who see the photo posted (on eBay, Alibaba, other sales sites, dating site, etc) can use the Ezy-Id to verify the photo on Uproov website. A live photo will have green Ezy-Id, while a red Ezy-id means it was a pre-existing photo.

Moreover, users can also limit when the file is viewed. Bulich told IBTimes that each time an image is Uproov'ed, a unique private key for each image is generated and is sent as a certificate in an email to the user for their safekeeping automatically.

"The email also contains other information, such that if Uproov no longer existed, each image can still be proved on the Blockchain by the user themselves using simple utility files. This is fundamental and means the users do not rely on Uproov, but only on the Blockchain”, he said.
