Abstract
An electronic device includes a memory and controller circuitry. The controller circuitry, responsive to a read request to read encrypted data stored in the memory, acquires, from metadata stored with the encrypted data in the memory, an ownership identifier identifying a type of writing entity that stored the encrypted data in the memory. The controller circuitry uses the ownership identifier to control whether, when responding to the read request, data decrypted from the encrypted data is returned or substitute data is returned instead of data decrypted from the encrypted data.
