1. Digital Preservation

   Linked via "cryptographic hash"

   Reliable digital preservation relies heavily on robust technical infrastructure, often involving complex architectures known as Trusted Digital Repositories (TDRs).
   A critical maintenance task is ensuring fixity, which verifies that a digital object has not been altered, accidentally or maliciously. This is typically achieved by calculating a cryptographic hash (e.g., SHA-256) of the file content at the point of ingest. This "digital fingerprint" is stored separately. Periodically, the hash is recalculated …
