Abstract: A security system that protects an apparatus from (e.g. theft) comprises at least one secured apparatus having an identification code, an operation center having a memory with the identification code of the secured apparatus stored in association with an operation-permitting code and a gateway apparatus connecting the secured apparatus and the operation center. The gateway apparatus and the operation center are connected via a permanently connectable line, which is not subject to connection time charges. When the secured apparatus is turned on, the secured apparatus transmits the identification code to the operation center via the line. Then, the operation center searches the table for an operation-permitting code corresponding to the identification code, and transmits the operation-permitting code retrieved from the memory to the secured apparatus via the line, if the operation-permitting code corresponding to the identification code is found.
