Abstract: A system and method for automatically updating a digital certificate prompts a user of a client computer to update a current digital certificate if a period of validity of the current digital certificate elapses or is about to elapse, and creates a new digital certificate if the current digital certificate needs to be updated. The system and method further deletes the current digital certificate, and loads the new digital certificate into a storage system of the client computer.

Abstract: A system and method for analyzing official notices of an electronically filed patent application are based on a file server that connects to patent office websites, a database, and client computers. An official notice of the patent application is downloaded from one of the patent office websites according to a download command from one of the client computers, and is converted to an image format document. Character data of the image format document are identified, and patent information of the electronically filed patent application are extracted from the character data using a regular expression. In addition, the patent information are analyzed to generate analysis results of the official notice according to the comparison.

Abstract: A processing digital noise method generates a matrix according to pixel values of pixels of a digital image, and selects a sub-matrix from the matrix. The sub-matrix has the same dimensions as a digital noise sample and includes a pixel value of a pixel selected from the digital image. The digital noise sample is represented as a matrix composed of 0 and 1. The method compares the sub-matrix with the digital noise sample to determine whether or not all values in the sub-matrix and the digital noise sample are the same. If all values are the same, the method further searches 1 from the sub-matrix for locating digital noise of the digital image, and removes the digital noise of the digital image by changing the pixel values of the digital noise from 1 to 0.
