Establishing the authenticity of a record is referred to as verification or authentication. Additional information is needed for this, such as information concerning the original intention behind the creation of the record and its subsequent management.
This can be done by establishing and preserving the original context of the record, and ensuring its adequate and uninterrupted management through an unbroken chain of custody. Such information is essential should research be necessary because of doubt over the authenticity of a record.
In archival law, it makes no difference whether a record is physical or digital.
