The method comprises encrypting data into a single data matrix image, such as a QR Code and allowing it to be decoded in such a way that different viewers can access different elements of the data, when it is being displayed on a mobile device such as a smart phone. An owner of the data first submits data through a program which encodes it as a data matrix image which is then displayed on the ownerâ s mobile display device. Software running on a reader device 320 viewing the data matrix image 330 displays information from the image and if some fields are encrypted 350, may prompt the user to provide an unlock key. After the correct unlock key has been submitted by the user, the software may display the encrypted fields 350 as well as the unencrypted fields 340. The data matrix image, or 2D barcode, could contain medical or other personal data. |
