Abstract: At the time of copy & paste, an item, a size and a paste content are recorded, and the importance of the paste is determined based on the number of pasted items, and a pasted data size relative to the overall file. Also, an item name and a change content are recorded, and when the manager inputs an important keyword (or unimportant keyword) in visualizing a file history, the importance is increased (or decreased) if the keyword is included in the item name or the change content. A function of displaying the file history in order of importance if the file history is displayed in table format in visualizing the file history, and a function of displaying, or highlighting, only the source file in which the importance is greater than or equal to a threshold set by the manager if the file history is displayed graphically are provided.

Abstract: The present invention is a stream data anomaly detection method for detecting an anomaly in input data received by a computer. The computer has: an input module for receiving the input data; an anomaly detection unit for detecting an anomaly in the input data; and an index management unit for calculating an index for the detection of an anomaly in the input data. The anomaly detection unit compares the received input data with the index and detects an anomaly in the input data when the difference between the value of the input data and the index satisfies a predetermined condition. The index management unit determines whether or not the index should be recalculated, and, when the index is determined to be recalculated, the index management unit recalculates a new index on the basis of the input data and substitutes the index with the calculated index.
