Abstract: Methods and related systems for secured and distributed data storage and communication are disclosed. For each byte of a given data set or file, data is split at the bit level and reassembled into a given number of meaningless data sets or files. One or more parity files are also generated to ensure availability and integrity of the data at all times. Each file is sent to a different and typically geographically distinct data storage location. When the information is required, the reverse process takes place. The only place where the information is reconstructed and accessible is at the point where it is required (the authorized users' computing devices or the organization's network reassembly point). The source information is never stored or accessible in any single storage location, making it highly secured. The process can be embodied into a system through various forms, including software, firmware, hardware or combination thereof.

Abstract: A motion-picture distributor (12) uses a computer system (22) to convert video signals from a master film (14) into serial video data (41) complying with DVD-Video standards. Further, the computer system (22) modifies the sequence of scene-data sets (42-1, 42-2, . . . ) constituting the data (41) and encrypts the data for each scene-data set, thus producing encrypted non-serial video data (45).

A theater (13) then uses a serialization apparatus (51) to read the data (45) from the DVD-ROMs (15-1, 15-2, . . . ), and sorts the scene-data sets in a correct sequence, thus producing encrypted serial video data (80). A motion picture projector (52) decrypts the data (80), thereby preparing the data (41). The data (41) are played back to view a movie. On the other hand, a movie distributor (12) may distribute the DVD-ROMs in a separated manner.

Abstract: A microfilm search device for distinguishing presence of frames from a change in quantity of transmitted light between the opposed optical fiber end faces between which a microfilm is placed. A pair of opposed blocks for holding optical fibers are arranged across the microfilm in a width direction with placing the microfilm therebetween. Light is guided into the optical fibers held by one block from a light source, passes through the microfilm, and enters the optical fibers held by other block. A quantity of entered light is detected by photosensor and an output thereof is binarized. Based on binarized signals, the presence of frames is determined. End portions of optical fibers on the side of the light source are bunched, and a bunched portion is detachably and non-rotatably held relative to one lamp. Frame detection condition due to light quantity can be uniform and maintained easy after disassembly, inspection, maintenance of the device.

Abstract: There is disclosed a microfilm search device which detects a frame or between-frames dimension from a density change in the running direction of a microfilm to determine the presence of frames and search for a desired frame. The detected density change is binarized to determine the dimension of the frame or between-frames. When detecting the length of a portion where the binarized signal representing film transparent portion continues, the dimension is corrected short. When detecting the length of a portion where the binarized signal representing film non-transparent portion continues, the dimension is corrected long. The frame or between-frames dimension can be detected with high accuracy to enhance the frame searching accuracy. Moreover, pulse signals outputted from an encoder are counted by a counter to monitor the film feeding amount, and the counter is reset when frames are detected and when the film feeding direction is reversed.

Abstract: There is disclosed a microfilm search method and device in which the presence of frames is accurately determined from a density change in a running direction of a microfilm. The detected density change is binarized into white and black synchronously with a sampling signal outputted for each predetermined feeding amount of the microfilm. The number of white signals included in a group of a predetermined number of binarized signals consecutive immediately before each sampling signal is successively obtained in response to the sampling signal. For the negative film, the presense of frames is determined by judging white (out-frame) when the number of white signals equals/exceeds a set value and by judging black (in-frame) when the number of white signals is less than the set value. The set value for determining the inside or outside of the frame may be changed when going into the frame from the outside of the frame and vice versa. Thereby, detection precision can further be raised.
