Abstract
A method of facilitating generation of a verifiable and immutable record. The method comprises, at a user device, obtaining a data file, generating an audit file for the data file, and separately hashing the data file and the audit file. The method further comprises storing the data file, the audit file and the hash values in a secure memory location, access to which is controlled, and preventing changes to the stored data by a user. When access is available to a remote server system, the stored data is sent to the remote server system and, in response, a notification received over confirming that the remote server system has verified the data file and the audit file and has created an immutable record of both. The user is then permitted to change the stored data file and or audit file in the secure memory location.
