COLOP Authentication App

Authenticate physical documents with blockchain within seconds!

Give credibility to important documents by sealing them with the COLOP e-mark secure solution. The printed QR-codes lead automatically to the corresponding verification app on the App Store. These QR-codes contain the one and only key to access all information which is fully encrypted and scrambled. For fast and simple authentication imprints, use the multiple-pages mode (User Registration needed). The following traceable details are then securely stored in a blockchain database:

• Authorized Organization
• Authorized Officer
• ID Number of the stamp device
• Location where the stamp was created
• Date, time and number of the stamp For documents that require the highest security, use the scan-page mode. Besides above details, three more important pieces of information are stored:
• Notes made during the stamp creation (optional)
• Third party verification (optional)
• Original image of the document
