Proof Of Storage (maidsafe part II), follow up video

by David Irvine

A follow-up post explaining how MaidSafe uses hashes to identify data and self-encryption for data security. The post distinguishes between “logical security” (encryption) and “physical security” (distributed storage across a decentralized network).

Logical Security

  • Self-encryption process secures data beyond known decryption abilities

    Physical Security

  • Data scattered across the globe on many machines owned by many people
  • No single entity knows what data they hold
  • Cannot disable or corrupt data in ways affecting network copies
  • No third party between user and their data
  • Autonomous network monitors nodes, not humans
  • Vandalism attempts result in automatic replication and de-ranking of offending machines (loss of safecoin earnings)

    Why Both Are Needed

  • Cloud providers monitor uploads/downloads, creating security leaks
  • Disks and tapes are searchable and may not be truly secure
  • Both physical and logical security are required for true data protection
