Fingerprint in Germany and implemented in both Germany and Japan, the Vucetich system (developed by a Croatian-born Buenos Aires Police Officer) was developed in Argentina and implemented throughout South America, and the Henry system was developed in India and implemented in most English-speaking countries. In the Henry system of classification, there are three basic fingerprint patterns: loop, whorl, and arch, which constitute 60–65%, 30–35%, and 5% of all fingerprints respectively. There are also more complex classification systems that break down patterns even further, into plain arches or tented arches, and into loops that may be radial or ulnar, depending on the
Attack patterns Attack patterns In computer science, attack patterns are a group of rigorous methods for finding bugs or errors in code related to computer security. Attack patterns are often used for testing purposes and are very important for ensuring that potential vulnerabilities are prevented. The attack patterns themselves can be used to highlight areas which need to be considered for security hardening in a software application. They also provide, either physically or in reference, the common solution pattern for preventing the attack. Such a practice can be termed "defensive coding patterns". Attack patterns define a series of repeatable steps that can
