Immutability and chain of custody refer to the concept of ensuring that digital records are secure and cannot be changed or tampered with. Immutability is the assurance that records remain unchanged after they have been created, while chain of custody is the process of keeping track of who has accessed and modified the records.
Immutability is achieved through the use of cryptographic techniques, such as digital signatures and hash functions. These techniques make it impossible to alter the data without leaving a trace. In addition, records can be stored on a distributed ledger, such as blockchain, to ensure that no single user is able to modify or delete the data. This provides an additional layer of security.
Chain of custody is maintained by keeping track of who has access to the records and when. This is often done with a log of user activity, which includes a timestamp for each action taken. The log is then cryptographically signed to ensure its integrity. This ensures that any changes to the records can be easily traced back to the responsible user.
Overall, immutability and chain of custody provide a high level of security for digital records, ensuring that they are kept secure and trustworthy.
