Abstract: A data encryption and decryption system is provided. An electronic encryption apparatus is configured to extract a feature set from plaintext data using a lossy algorithm, encrypt the feature set, send it to a feature server, receive an access control list (ACL), send this to a key server, and receive back an encryption key, which is used to encrypt the plaintext data. A data identifier is also exchanged. An electronic decryption apparatus is configured to send the data identifier to the key server, identify an entity to the key server, receive a decryption key from the key server, and decrypt the encrypted data. The key server stores the ACL and data identifier in mutual association. When it receives a data identifier and entity identifier from the electronic decryption apparatus, it checks the entity is on the ACL associated with the data identifier, and returns the decryption key.

Abstract: Novel techniques are disclosed for the direct fluoridation of organic compounds by treatment with fluorine gas in a reaction mixture comprising hydrofluoric acid and at least one of water and formic acid. The techniques are particularly applicable to aromatic organic compounds and beta-dicarbonyl compounds. Increased efficiency of reaction is observed, together with improvements in yield and purity of product, with especially beneficial effects being apparent at low temperatures.

Abstract: A disk drive rotary actuator has a head arm rotatable about a pillar. The pillar has abutments engaging a rolling member located in a recess in the head arm. The rolling member and pillar provide a space between abutment surfaces through which a flexure plate passes. A spring holds the pillar and arm together with the rolling member between them.
