US20190068360

1. A method for maintaining a cryptographic distributed ledger for examination records, the method comprising: (5) (8)

receiving a digitized completed examination, the digitized completed examination representing an immutable record of a completion of an examination by a first party;

storing the digitized completed examination within a blockchain that provides a verifiable record of examination activities;

verifying the authenticity of the stored digitized completed examination against a historical record of the examination, and generate an alert if an anomaly is detected;

receiving a digitized marked examination, the digitized marked examination representing an immutable record of a marking, by a second party, of the completed examination;

storing the digitized marked examination within the blockchain;

verifying the authenticity of the stored digitized marked examination against the stored digitized completed examination, and generate an alert if an anomaly is detected; and

communicating the alert, when generated, to a user via a user interface,

wherein the alert, when generated, comprises a message determined by the detected anomaly.

2. The method of claim 1, further comprising electronically delivering the completed examination to the second party for marking. (0)

3. The method of claim 1, wherein the storing the digitized completed examination within a blockchain comprising encrypting the digitized completed examination using a public key associated with the first party. (0)

4. The method of claim 1, wherein the storing the digitized marked examination within the blockchain comprises encrypting the digitized marked examination using a public key associated with the second party. (0)

5. The method of claim 1, wherein the blockchain comprises a plurality of examination records, each examination record comprising a plurality of examination activities and an overall mark, and wherein the method further comprises aggregating a plurality of overall marks from the blockchain to form a report, and communicating the report to a designated user. (0)

6. The method of claim 1, wherein the method further comprises determining an overall mark based on the digitized marked examination and storing the overall mark onto the blockchain. (0)

7. A method for maintaining verified examination records, the method comprising: (2) (4)

maintaining a secure chain of data blocks at a given computing node, wherein the given computing node is part of a set of computing nodes in a distributed network of computing nodes wherein each of the set of computing nodes maintains the secure chain of data blocks, wherein the secure chain of data blocks maintained at each computing node comprises one or more data blocks that respectively represent one or more activities associated with an examination;

adding at least one data block to the secure chain of data blocks maintained at the given computing node in response to determining that examination activity data associated with the at least one data block is valid;

generating an alert in response to determining that examination activity data associated with the at least one data block contains an anomaly;

wherein the maintaining and adding steps are implemented via at least one processor operatively coupled to a memory associated with the given computing node.

8. The method of claim 7, wherein the secure chain of data blocks represents an activity log of the examination through time. (0)

9. The method of claim 7, wherein the alert alters a user interface on a user device or a user interface on an output terminal of a server. (0)
