Abstract: An intermediary apparatus, an intermediary method, and a computer program product thereof for storing data in a storage apparatus, and a data storage system comprising the same are provided. The storage apparatus has a storage zone with a signature field, and the signature field stores a first signature value. The data has index information and a data signature value. After searching out the storage zone according to the index information, the intermediary apparatus extracts the first signature value from the storage zone, and then determines if the data has been stored in the storage zone according to the first signature value and the data signature value. If not, the intermediary apparatus writes the data into the storage zone; otherwise, ignores the data.

Abstract: A method and a system for analyzing signals from an electronic tag and a recording medium thereof are provided. The method includes the following steps. At least one reading point is defined, wherein each of the reading points includes at least one reader device. A plurality of states is defined according to logical combinations of the reading points. At least one predetermined state sequence is defined according to sequential permutations of the states. Signals are received from the electronic tag through the reader devices of the reader points. The signals received from the electronic tag are converted into the states according to the content of the signals and the definition of the reading points through a logical processing procedure, and a temporary state sequence is generated. The temporary state sequence is compared with the predetermined state sequences, and a corresponding response procedure is executed according to the comparison result.
