By a News Reporter-Staff News Editor at Life Science Weekly -- From Washington, D.C., NewsRx journalists report that a patent application by the inventor Chen, Chih-Ming (New Taipei City, TW), filed on September 26, 2016, was made available online on November 30, 2017 (see also Electronics Companies).

The patent's assignee is Wistron Corporation.

News editors obtained the following quote from the background information supplied by the inventors: "Field of the Invention

"The invention relates to a data security mechanism, and particularly relates to a protecting method and system for malicious code, and a monitor apparatus.

"Description of Related Art

"With the development and innovation of science and technology, internet facilitates global information exchange. Also, lifestyle of more and more people is gradually integrated into a virtual world from a real society. Thus, many people are willing to attack maliciously through the internet. A computer virus is one of malicious programs, which may make the program self-replicate, infect other normal programs in a computer, or damage a computer system, thereby causing the computer can not work normally.

"With the popularity of the Internet of Things (IoT), the number and type of the virus are significantly increased. Traditional antivirus systems need to obtain virus patterns, and then build the virus patterns by artificially studying behaviors thereof to deploy, which is time-consuming, labor-consuming, and costly. In the generation of IoT, the traditional antivirus systems have not kept up with the speed of evolution of the virus. There is a need for a way to make the antivirus systems evolve with the virus, which is fast enough."

As a supplement to the background information on this patent application, NewsRx correspondents also obtained the inventor's summary information for this patent application: "The invention provides a protecting method and system for malicious code, and a monitor apparatus, which combines a variety of antivirus systems for an evolution direction of the malicious code so as to form a monitor module, such that the monitor module moves toward a better direction and evolves independently.

"The invention provides a protecting method for malicious code including the following steps. A monitor module obtained from a combination of a plurality of antivirus systems is circulated in a communication system by a monitor apparatus, so as to monitor at least one electronic apparatus in the communication system. When the monitor module is circulated to one of the electronic apparatuses in the communication system, whether there is a malicious code is detected by the monitor module. When the malicious code is detected by the monitor module, a protection result is decided by the monitor module, and one or more corresponding process actions are executed based on the protection result. Herein, when the malicious code is detected by the monitor module, the step of obtaining the protection result by the monitor module includes that, in a condition that the monitor module is an admixture model, at least one of the antivirus systems is selected as a selected module, and the protection result corresponding to the malicious code is obtained by the selected module; in a condition that the monitor module is an association model, the protection result corresponding to the malicious code is obtained by associating the antivirus systems.

"According to an embodiment of the invention, in the condition that the monitor module is the admixture model, the protecting method for malicious code includes that, based on an evolution bias vector decided by the monitor apparatus, one of the plurality of antivirus systems is selected as the selected module. Based on a probability vector decided by the selected module, a representative cluster corresponding to the malicious code is identified by the selected module. A set of the process actions corresponding to the representative cluster is identified according to the evolution bias vector and the probability vector, and the set of process actions is used as the protection result.

"According to an embodiment of the invention, in the condition that the monitor module is the association model, the protecting method for malicious code includes that, an evolution bias vector decided by the monitor apparatus is obtained, wherein the evolution bias vector decides a correlation weight between each the antivirus system and the malicious code. In each the antivirus system, based on a probability vector decided by each the antivirus system, a representative cluster corresponding to the malicious code in each the antivirus system is identified. A set of the process actions corresponding to the plurality of representative clusters of the antivirus systems is identified according to the evolution bias vector and the probability vector, and the set of process actions is used as the protection result.

"According to an embodiment of the invention, after deciding the protection result by the monitor module, the protecting method for malicious code further includes that, a multi objective optimization algorithm is executed to obtain an optimal objective solution from a plurality of objective solutions included in the protection result, so as to set the optimal objective solution as the final process action.

"According to an embodiment of the invention, the protecting method for malicious code further includes that, a plurality of aggressive behaviors corresponding to the malicious code received from the electronic apparatus are analyzed to obtain a behavior characteristic vector by the monitor apparatus, and a behavior prediction is executed based on the behavior characteristic vector to obtain an evolution bias vector wherein the evolution bias vector relates to the malicious code and the plurality of antivirus systems included in the monitor module. When an abnormal message is received from one of the electronic apparatuses, the monitor module is circulated to the electronic apparatus which transmits the abnormal message, and whether there is the malicious code is detected by the monitor module.

"According to an embodiment of the invention, the plurality of antivirus systems included in the monitor module are a tree hierarchical structure, and a plurality of layers of the tree hierarchical structure belong to the admixture model or the association model respectively.

"The invention provides a protecting system for malicious code including an electronic apparatus and a monitor apparatus. The electronic apparatus and the monitor apparatus are located in a communication system. The monitor apparatus communicates with each the electronic apparatus by a communication device and circulates a monitor module obtained from a combination of a plurality of antivirus systems in the communication system, so as to monitor each the electronic apparatus in the communication system. When the monitor module is circulated to the electronic apparatus, the electronic apparatus detects whether there is a malicious code by the monitor module. Also, when the malicious code is detected by the monitor module, the electronic apparatus decides a protection result by the monitor module and executes one or more corresponding process actions based on the protection result. Herein, when the malicious code is detected by the monitor module in a condition that the monitor module is an admixture model, the electronic apparatus selects at least one of the antivirus systems as a selected module and obtains the protection result corresponding to the malicious code by the selected module. When the malicious code is detected by the monitor module in a condition that the monitor module is an association model, the electronic apparatus obtains the protection result corresponding to the malicious code by associating the antivirus systems.

"The invention provides a monitor apparatus including a communication device, a storage device, and a processor. The processor is coupled to the communication device and the storage device. The communication device establishes a connection with an electronic apparatus of a communication system. The storage device includes a behavior analysis module and a behavior prediction module. The processor circulates a monitor module obtained from a combination of a plurality of antivirus systems to the electronic apparatus in the communication system by the communication device, so as to monitor the electronic apparatus in the communication system. The processor drives the behavior analysis module to analyze at least one aggressive behavior corresponding to at least one malicious code received from the electronic apparatus to obtain a behavior characteristic vector, and the processor drives the behavior prediction module to execute a behavior prediction based on the behavior characteristic vector to obtain an evolution bias vector wherein the evolution bias vector relates to the malicious code and the antivirus systems included in the monitor module, so as to decide that the monitor module selects at least one of the plurality of antivirus systems to decide a protection result or associates the plurality of antivirus systems to decide the protection result by the evolution bias vector.

"Based on the above, the monitor module obtained from a combination of the plurality of antivirus systems is circulated in the communication system by the monitor apparatus, so as to monitor each the electronic apparatus in the communication system. By the analysis of the monitor apparatus, a variety of antivirus systems can be combined for the evolution direction of the malicious code to form the monitor module, such that the monitor module moves toward a better direction and evolves independently.

"In order to make the aforementioned features and advantages of the disclosure more comprehensible, embodiments accompanied with figures are described in detail below."
