Provided is a more versatile technique that makes it possible to input dummy information in response to an attacker seeking to collect normal information that cannot be replaced with dummy information. In the present invention, a dummy information insertion device inserts dummy information into a second location that is determined using: first location information indicating a first location that contains normal information, from among all normal information in a computer, which cannot be replaced with other information; and insertion condition information that indicates conditions for determining the second location into which dummy information is to be inserted, with such dummy information resembling the normal information that cannot be replaced and not being present in the computer or in a local network connected to the computer.

A relay apparatus, which is connected between an information terminal and at least one peripheral device communicatively connected to the information terminal and supplying information to the information terminal, is recognized as a peripheral device by the information terminal, and recognized as an information terminal by the peripheral device. The relay apparatus comprises authentication means for authenticating a user using the information terminal by operating the peripheral device and control means for controlling relaying of an operation signal of the peripheral device operated by the user to the information terminal, based on an authentication result of the user.

This handwriting input device is equipped with an object to be coated, a detection means, and a display means. The object to be coatedis transparent or translucent. When a letter or a figure is written or drawn with a coating material, the detection meansdetects a position in which the coating material attaches on the object to be coated. The display meanscauses a visual change in accordance with the position in which attachment of the coating material is detected by the detection means, thereby displaying the letter or figure written or drawn with the coating material.

During a communication, the radio connection quality is measured so as to detect and store a generation time, an end time, and a continuation time of quality degradation. Upon a communication end, the end cause is judged. If the communication end is caused by a user operation, a causal connection between the communication end and the quality degradation is judged according to temporal relationship between the generation time of the quality degradation and the communication end time. That is, it is judged whether the communication end caused by the user operation is a phenomenon that the user has terminated the communication because of the communication quality degradation or other reason. Thus the communication end reasons are divided into at least two types and accumulated.

Power of signal light injected to a Raman amplification medium is measured or estimated by calculation and ratio of the gain between forward pump light and backward pump light is controlled according to the result of the measurement or calculation. Wavelengths used in the forward pumping are optimally allocated.

Raman amplification control method, optical communication system, optical amplifier and program

When Raman amplification is performed, the occurrence of lightwaves through FWM in a wavelength band of input signal light is suppressed, thereby avoiding deterioration of the signal quality. Allocation of lightwaves of the pumping light is controlled so that, wavelengths of lightwaves arising through a nonlinear effect of pumping lights generated by a pumping means or of pumping lights and input signal light, or both, are not within the wavelength band of the input signal light.
