Security O M: Use of Linux backdoor intrusion detection tools
1. Introduction to rootkit
Rootkit is the most common backdoor tool in Linux. It mainly replaces system files for intrusion and concealment. This Trojan is more dangerous and concealed than a common backdoor, it is difficult to find such Trojans through common detection tools and detection methods. Th

In biometric systems, in order to prevent malicious people from forging and stealing other people's biological characteristics for identity authentication, biometric systems need to have a live detection function, that is, to determine whether the submitted biological characteristics come from living individuals.

JavaScript feature detection is not browser detectionDetailed source reference:. net/article/21834.htm ">http://www.111cn.net/article/21834.htmAt first, the front-end engineers objected to browser testing, which they thought was bad because it was not a future-oriented code and could not adapt to new browsers. A better approach is to use feature detection, just like this:Copy code code as follows:if (Naviga
Pedestrian detection plays a vital role in many applications in the computer vision field, such as video surveillance, vehicle driver assistance systems, and human motion capturing systems. image Pedestrian detection methods can be divided into two categories: contour matching and apparent features. the apparent feature is defined as the image feature space (also called the descriptive operator). It can be

Analysis of malicious software detection mechanism bypass by SHA-1 and SHA-2 combination
Symantec recently posted on its blog that it is aware of a disturbing attack trend in malware. After stealing a normal SHA-2 certificate, malware can survive more easily.SHA-1 is insecure.

Linux hard disk Performance Detection and linux hard disk Detection
For today's computers, the performance of the entire computer is mainly affected by the disk I/O speed, and the speed of memory, CPU, and motherboard bus has become very fast.Basic detection method 1. dd command

after scanning the QR Code extraction task, it is necessary to extract the ID number from the ID image and then call the colleague to identify it. the previous connected-domain detection algorithm compares "brute force" because once it detects a large area, all the inner areas of the area will no longer exist. Therefore, in the connected domain detection, the first step is to remove the possible white edge

I. Basic knowledge of the stinker
1.1 What is a stinking detector?
Sniff is an English form of the stinker. It can be understood as a computer-installed eavesdropping device. It can be used to snoop a large amount of information on the computer's network. A simple explanation: A is a telephone eavesdropping device. A can be used to intercept the communi
Event detection, which detects whether an event exists (available) in a different browser, is also important in the process of writing JavaScript, such as the Mouseenter/mouseleave event is practical, but not all browsers provide standard support, So you need to simulate yourself manually, namely:
function addEvent(element, name, handler) {
if (name == 'mouseenter' !hasEvent(name, element)) {
//通过其他手段模拟mouseenter事件
}
//正常的事件注册
};

Due to the needs of the development of monitoring, there are still a lot of research on foreground detection, and there are also a lot of new methods and ideas. My personal knowledge is summarized as follows:

Based on the characteristics of hep (histograms of equivalent patterns "1"), which has good texture classification effect, LBP (local binary patterns "2") is the most commonly used feature under the HEP Framework and has a brightness, Rotation and other good invariant properties. In the block-based video smoke detection, it is often used as a feature of texture classification. However, the image of a block is localized. This article mainly proposes th
Do a website of the Android client, the user installed to their mobile phone, if I have a new version how to do? To have a version update feature.
Original version detection is best done automatically. But if every time you open the program, you have to first detect a round, is a waste, after all, version update is a small probability of things. Perhaps the process can be opened, judge the time, a single day on the test, the date does not detect, or r
