Disclosed are various embodiments for identifying related collections of items within an item universe. Related collections of items can be identified based upon title similarity or a degree of overlap between collections of items. Additionally, relationships between collections of items can be generated if the collections have identical or nearly identical collection titles.

A multi-tiered encryption system efficiently regulates the use of encryption keys to encrypt and decrypt data. The system can include one or more encryption tiers. Each encryption tier can include a computing node programmed to service encryption and/or decryption requests and a key store to store encryption keys. At a root encryption tier, an unencrypted root encryption key can be stored in the key store. Each subsequent encryption tier includes encryption keys that are encrypted by encryption keys stored at a lower encryption tier. The encryption tiers collectively implement an encryption policy in which keys are automatically created and rotated such that a requesting device can request encryption services from the multi-tiered encryption system and receive the encryption services independent of key creation or key rotation and without access to the unencrypted root encryption key.
