Data encryption as an access control

Data encryption provides an additional level of security and privacy over message transmissions. Data encryption is the re-encoding of electronic signals to disguise their meaning. The original data can only be read by the person or device that knows the key that decodes the message. Encryption processing can be implemented utilizing hardware or software and can be applied in a variety of communication situations.
