Content integrity refers to the accuracy and consistency (validity) of content over its lifecycle in Swarm storage. Integrity can be lost at various levels:
- Human error or tampering
- Transfer errors, including unintended alterations or data compromise going to or from storage
- Cyber threats (bugs, viruses/malware, hacking)
- Compromised hardware, such as a device or disk crash
- Physical compromise to devices
Best practices for content integrity include multiple approaches:
- Input validation, to preclude the entering of invalid data
- Error detection/data validation, to identify errors in data transmission
- Security measures, such as access control and data encryption
