摘要： A terminal device that can, when delivering information to an other terminal device, control delivery of the information from a primary delivery destination to a secondary delivery destination is provided. The terminal device stores a primary delivery condition regarding whether delivery of the information to the primary delivery destination is prohibited or permitted, and trustability showing a degree of trust of a user in the primary delivery destination. The terminal device judges whether or not to deliver the information to the primary delivery destination, by using the primary delivery condition. When judging to deliver the information, the terminal device calculates a secondary delivery condition using the trustability and the primary delivery condition, the secondary delivery condition regarding whether delivery of the information from the primary delivery destination to the secondary delivery destination is prohibited or permitted. The terminal device sends the generated secondary delivery condition to the primary delivery destination.

摘要： An encryption apparatus prevents plaintext data from leaking even if accumulated data is analyzed, while preventing the size of encrypted data from increasing. The encryption apparatus encrypts a data piece that is smaller than a unit length and stores management information indicating a used area within an encryption area defined based on the unit length. The used area is an area already used for encryption. When encrypting a new data piece that is smaller than the unit length, the encryption apparatus generates encrypted data by adding the new data piece to an unused area within the encryption area with reference to the management information. The unused area is an area not yet used for encryption. The encryption apparatus updates the management information to include an area for the new data piece into the used area, after generating the encrypted data.
