Learn about data security for objects stored on 4EVERLAND.
All data stored on 4EVERLAND has an inherently high level of data security. Objects are stored in decentralised networks. Currently, we support IPFS, Arweave and Internet computer networks.
The decentralised network consists of different peer-to-peer networks. These networks consist of storage nodes spread across the globe. Some decentralised networks use erasure coding, also known as Reed-Solomon coding, which is a data storage algorithm that allows objects to be stored in parts rather than in their entirety.
Each object stored in a decentralised storage network is broken up into tens or hundreds of fragments, also known as shards. Each shard is encrypted during data transmission and when the data is at rest. While the data may be distributed across multiple nodes, only a fraction of it is needed to reassemble it.
Each bit of data stored on a node is itself worthless. This ensures that the data is reliable, even if any individual node is corrupted or damaged. To access the object, you need to provide the storage network with an individual encryption key or hash.
The network then retrieves the file fragments stored on different nodes, reassembles them into an object and sends them to the user. This object is only available to the person who has the encryption key.
