摘要： Methods for using integrity checking techniques to identify and locate computer viruses are provided. A method for virus localization for each of three types of virus infections is provided, including the steps of computing a sequence of file blocks, calculating hashes for the sequences of file blocks from a host file and calculating hashes for the same or related sequences of file blocks from an infected file, and comparing the hashes from host file to the hashes from the infected file from the same or related sequences of file blocks such that when some of said first hashes and said second hashes do not match, a location of a virus is output. Methods are provided for computing the sequence of file blocks depending on the type of virus infection, and for calculating the hashes using a collision resistant hash function, a digital signature scheme, a message authentication code, or a pseudo-random function.

摘要： The present invention provides system and method for delayed answering of a call to a cellular phone which can operate in either a distributed or a centralized manner. In particular, the system and method according to the present invention allows the cellular phone user upon receiving a call to play a message to the caller, such as informing the caller to “hold on” for a short time and that the user will be available shortly. The present invention provides a number of advantageous alternatives to provide a cellular phone user flexibility in answering incoming calls.
