  • Publication number: 20160065613
    Abstract: A system and method for detecting malicious code based on the Web are disclosed herein. The system includes a Uniform Resource Locator (URL) collection unit, a data crawling unit, a malicious code candidate extraction unit, and a secure pattern filtering unit. The URL collection unit collects and stores the URL information of a web server. The data crawling unit crawls and stores the contents data of a website. The malicious code candidate extraction unit detects a pattern, matching previously stored malicious pattern information, in the stored data, and extracts an event including the detected pattern as a malicious code candidate. The secure pattern filtering unit detects a pattern, matching previously stored secure pattern information known as being secure, in the extracted malicious code candidate, filters out the event including the detected pattern from the extracted malicious code candidate, and outputs a remaining malicious code candidate as malicious code.

  • Patent number: 9276172
    Abstract: It is provided a method of manufacturing a display device for which the damage caused to the display panel due to processing at high temperatures is reduced. The method of manufacturing a display device includes: preparing a carrier substrate including a surface treated region; laying a mother substrate on the carrier substrate; progressing a process of forming a thin film on the mother substrate; and separating the carrier substrate from the mother substrate by using the surface treated region as an initial separation point. Bonding is formed between the carrier substrate and the mother substrate during forming the thin film over the areas that are not surface treated. The two substrates may be separated by disposing permeating oil on the surface treated region wherefrom oil permeates through the remaining regions by osmotic pressure. This way damage caused to the display panel during thin film processing is reduced.
