摘要： The content of operations is identified and an alert is generated to an operation having a high risk of information leakage.An agent monitors, for example, operations performed with respect to a dialogue displayed on a client PC. If a file is selected by an operation performed with respect to the displayed dialogue, the agent assigns an identifier indicating a source for the file to the file. If the file is sent as an attached file, the agent identifies an output destination for the attached file as well as the source for the attached file; and if the output destination for the attached file is an external Web server and the source for the attached file is a mail server, the agent generates an alert by determining that an unauthorized operation has been executed; and then sends the generated alert to a management server.

摘要： The present invention provides a system for detecting and recording a user operation with respect to a web application. This system extracts from an application screen both a character string input element for the user to input a character string and an execution instruction element for instructing the web application to execute a prescribed operation. This system infers the role of the character string input element and execution instruction element in the web application. This system associates the character string input element with the execution instruction element, and extracts an inputted character string, which is inputted to the character string input element. This system creates user operation record data, which is recorded with a user operation, based on template data and the inputted character string.

摘要： An operational circuit for performing an operation of an arbitrary number of input data pieces by using a DMA transfer according to a descriptor control and output results. The arbitrary number of input data pieces are divided into a plurality of pieces to perform an operation processing without performing the operation of the arbitrary number of input data pieces at a time. The operational circuit once stores an intermediate result for each of the divided operations in an external storage device, performs an operation processing read with an intermediate result in the next operation processing, and obtains a final result by repeating these operation processings. The operation is performed at a cyclic unit of processing corresponding to the number of address registers provided in the operational circuit.
