    摘要: Malware detection systems are presented in which a list is constructed of enterprise hosts to or from which each given enterprise network host sends or receives packets within a current measurement period and statistics are accumulated based on two or more measurement period lists, with a count value being derived from the statistics to indicate the number of other hosts to or from which each monitored host sent or received packets, and one or more monitored hosts may be identified as suspected of being infected with slow and/or distributed scanning malware for which the count value exceeds a threshold value.

    摘要: Digital marks (so-called fingerprints and watermarks) serve two basic purposes: (1) Investigative: the owner reads a fingerprint to determine how the marked entity leaked; and (2) Legal: the owner must prove in court that (a) there is a watermark (a concealed copyright message), and (b) it is the owner's. The main difficulty of item (2) is that the first use of the watermark software reveals the watermarking method to the public so that hostile parties are equipped to remove or damage its watermarks. The invention uses tamper-resistant software encoding techniques to protect the digital mark extractor algorithm, frustrating the attacks of hostile parties in two ways: the resulting code is obscure (that is, its inner workings are incomprehensible; and chaotic (that is, a modification at any point will almost certainly produce a nonsense program.
