A user using a client computer registers with a server computer over a computer network by submitting a biometric scan of a body part of the user. The user commands the client computer to encrypt an electronic file. The client computer generates a private key, encrypts the electronic file and transmits the key to the server computer. The client computer saves the encrypted file. The encrypted file and the key are saved at different physical locations. The owner of the file is able to grant permission to other registered users to unlock the encrypted file.

Secure information storage and retrieval apparatus and method

A fluid treatment system comprising at least two cylindrical vessels, wherein each vessel contains at least one treatment medium selected from ion exchange resins, polymeric adsorbents, inorganic adsorbents and activated carbon; each vessel has at each end a flat head and a fractal liquid transfer manifold; and the system comprises at least one membrane degasifier unit.

Fluid treatment system

Ion exchange resin beds used for ammonia-cycle condensate polishing show enhanced selectivity for sodium ions over ammonium ions when conventional, monosulfonated cation exchange resin is replaced with polysulfonated cation exchange resin. This enhanced selectivity results in a lower concentration of sodium ion leakage and longer bed life to critical leakage, compared with conventional, monosulfonated resins.
