Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a mobile terminal having an electric shock type security module,

The present invention relates to a recording medium destruction method for destroying information recorded on a recording medium such as a magnetic recording medium such as a cellular phone, an optical recording medium, and a recording sheet with unreproducible (unreadable).

In general, when a terminal is lost or stolen, a person who learns and owns the terminal is highly likely to turn off the power switch of the terminal in order to privatize the terminal. Also, crucial and important user information such as contact numbers, contact addresses, and important information stored in the form of messages (or images, etc.) in the learned terminal may be easily exploited by an immoral person.

In order to solve such a problem, US Patent Application Publication No. 20060234679 A1, which is a conventional method, proposes a method and system for protecting information in a terminal when the terminal is stolen or lost. According to US 20060234679 A1, a user of a terminal can perform an information protection process after informing his / her own information to an information protection system to perform a user authentication process.

In order to protect the data stored in the lost terminal, the information protection can protect one or more information by performing a process such as stopping the original function of the terminal, preventing data reading, and deleting data from the terminal.

Another conventional method, US 20070178881 A1, proposes a method and system for remotely accessing subscriber data associated with a stolen or lost terminal using a message function. That is, in US 20070178881 A1, a terminal user sends a message to a terminal to prohibit illegal access for the purpose of unintended use of data stored in a lost terminal. Such a message is intended to control a stolen or lost terminal, such as permanent deletion of data stored in the memory, blocking of data stored in the terminal from unintended recipients, or recovery of a portion of the data before blocking the network connection .

However, in the above-mentioned conventional method, a " special switch off "must be configured before the terminal is stolen or lost, and a" mechanical latch " There is a problem to be performed in advance.
