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 are things like weaknesses in protocols, authentication strategies, and system modularization. These are more logic-based attacks than actual bit-manipulation attacks. Physical attack patterns are targeted at the code itself. These are things such as SQL injection attacks, buffer overflows, race conditions, and some of the more common forms of attacks that have become popular in the news. External attack patterns include attacks such as trojan horse attacks, viruses, and worms. These are not generally solvable by software-design approaches because they operate relatively independently from the attacked program. However, vulnerabilities in a piece of software can lead to these attacks being
