The Proof of Existence Solution will help you to prove that a document/file/picture was created on a particular date and time via blockchain technology. From that point on, anyone with access to the data can verify it against the blockchain version. Future changes to the data will show up like a sore thumb and can be detected quickly by any connected system.

Solution Overview

Immutable yet tamper-proof is the nature of blockchain, once the data been written onto the blockchain, it cannot be changed. You can upload your document/file/picture to our system, it will generate a digital sign by hashing all these data via certain algorithm, then the data will be encrypted and stored safely, meanwhile the digital sign will be written onto the blockchain, thus any future change of the original data will be detected easily, and you can prove its existence anytime you want, all in all, written once written forever.
