Abstract: A network security system and methodology that securely defenses against current and future threats. According to the invention, anti-phishing method is utilized for protecting a computer system. In one embodiment of the invention, anti-phishing method comprises the steps of: detecting a user being submitting predetermined data to a predetermined website; intercepting the predetermined data; verifying whether address of the predetermined website is identical to an address of a secured website; and enabling and/or disabling the submission of the predetermined data.

Abstract: An optical device includes: a collimator; at least one anamorphic pair of prisms optically coupled to the collimator; a diffraction grating optically coupled to the at least one anamorphic pair of prisms at a side opposite to the collimator; and a focusing lens optically coupled to the diffraction grating. The anamorphic pair of prisms permits light incident upon the diffraction grating to be relatively narrow in a dimension perpendicular to the dispersive direction of the grating so that the grating can produce high spectral resolution while preserving compact system size and simplicity.

Abstract: A remote manipulating system and methodology that allows the user to easily operate specific functions. According to the invention, remote manipulating method is suitable for a host system coupled to a hand-operated apparatus. The method of the invention includes the step of outputting a signal from the hand-operated apparatus to the host system. The method also includes the steps of analyzing the signal to invoke at least one predetermined function upon receiving the signal and sending a predetermined message corresponding to the at least one predetermined function to a remote system over the computer network. The method further includes the steps of implementing the at least one predetermined function corresponding to the predetermined message for remote training, responsive to the remote system receiving the predetermined message issued from the host system. A system is also disclosed to carry out the method steps of the invention.
