| Please note that the content of this book primarily consists of articles
available from Wikipedia or other free sources online.Locksmithing began
as the science and art of making and defeating locks. A lock is a
mechanism that secures buildings, rooms, cabinets, objects, or other
storage facilities. A key is often used to open a lock. Means of opening
a lock may include two-factor authentication for greater security, such
as requiring both something you know and something you have.
Locksmithing is one of the earliest forms of security engineering. Lock
picking was one of the first methods of cracking security systems. The
oldest known lock was approximately 4,000 years old and was of Egyptian
make. It was found in the ruins of the Emperor Sargon II's palace in
Khorsabad. It used the same pin tumbler principle employed by many
modern locks. |
