Abstract
Abstract A device is disclosed for retrieving information from a secure electronic information source, wherein at least some of the information is in encrypted form and may be decrypted for use. The device comprises: (a) a computer, having an input device and a display device, for selecting information to be retrieved from the information source; (b) an information retrieval device, coupled to the computer, for retrieving the selected information from the information source; (c) a decryption device, coupled to the computer, for decrypting at least portions of the selected information retrieved from the information source; and (d) a data logging device, coupled to the computer, for maintaining a data log of the selected information as it is retrieved from said information source and decrypted. According to the invention, a unique brand code is automatically, electronically added to at least some of the selected and decrypted information, and to the data log.
