System and method for shared secret encryption and verification of recordings of meeting proceedings

An application to enable creation of recordings of a meeting using a first and a second user device, wherein

• the application is made available for installation on the first and the second user device;
• the application enables the first user device and the second user device to couple to a blockchain via a network;
• the application enables an initiation of the recordings at the first user device and the second user device,
• the initiation comprising coupling the first and the second user device together using a first proximity communication;
• the application enables an establishment, based on the initiation, of a symmetric key to encrypt and decrypt further proximity communications between the first and the second user device, and
• the further proximity communications comprise exchanging one or more portions of data between the first and the second user device;
• the application enables creation of a first signed package at the first user device based on the one or more portions of data and using a first hash;
• the application enables creation of a second signed package at the second user device based on the one or more portions of data and using a second hash;
• and
• the application enables storage of the first and second signed packages on the blockchain.
