Abstract
An information processing device including: a data processing unit that generates content for transmitting to a client; and a communication unit that transmits the generated content of the data processing unit, wherein the data processing unit generates, based on basic encrypted content having a plurality of units that each includes a SEED that is data for encryption key generation and a block that is encrypted data that is encrypted by an encryption key generated using the SEED, each data of (a) converted encrypted content on which conversion processing to replace the SEED with dummy data or to delete the SEED is performed, and (b) encrypted SEED that is the SEED encrypted by content transmission processing or by individual keys that are different by units of users at a transmission destination, and transmits the generated converted encrypted content and encrypted SEED as data provided to the client via the communication unit.
