  • Publication number: 20120159629
    Abstract: A method for detecting a malicious script is provided. A plurality of distribution eigenvalues are generated according to a plurality of function names of a web script. After the distribution eigenvalues are inputted to a hidden markov model (HMM), probabilities respectively corresponding to a normal state and an abnormal state are calculated. Accordingly, whether the web script is malicious or not can be determined according to the probabilities. Even an attacker attempts to change the event order, insert a new event or replace an event with a new one to avoid detection, the method can still recognize the intent hidden in the web script by using the HMM for event modeling. As such, the method may be applied in detection of obfuscated malicious scripts.

  • Publication number: 20110090328
    Abstract: A portable microscope includes an image sensing module and an objective lens ascending/descending module. The objective lens ascending/descending module includes a rotatable roller, a sliding track member and an objective lens assembly. A first thread structure is formed on an inner wall of the rotatable roller. The sliding track member is disposed within the rotatable roller, and includes at least two parallel sliding tracks for defining a channel. The objective lens assembly is coupled to the sliding track member and slidable along the channel. A second thread structure mating with the first thread structure is formed on an external surface of the objective lens assembly. Upon rotation of the rotatable roller, the objective lens assembly is moved along the channel of the sliding track member, thereby adjusting the size of an image acquired by the image sensing module.
