Protection method for use in portable communication device

A portable communication device with data protection function comprising:

• a storing device for storing a specific command, said specific command is generated by building a connection between said portable communication device and said designated communication device, said portable communication device having a first phone number, a first hardware identification serial number, and a designated communication device having a second phone number, and a second hardware identification serial number, and generating the specific command according the first phone number, the first hardware identification serial number, the second phone number, and the second hardware identification serial number, wherein said specific command is a combination of a first command and a second command;
• said first command is encoded by said first phone number and said first hardware identification serial number by Message-Digest algorithm 5 (MD5);
• and said second command is encoded by said second phone number and said second hardware identification serial number by Message-Digest algorithm 5 (MD5);
• a transceiver unit for receiving a message:
• and
• a control unit for determining whether said message received by said portable communication device comprises said specific command by comparing said specific command that had been previously stored in said storing device with content of said received message that is presently received, and performing a protection mechanism for protecting the information stored in said portable communication device when said message received by said transceiver unit comprises said specific command.

A protection method used in a portable communication device, comprising the following steps:

• providing a first phone number and a first hardware identification serial number for said portable communication device;
• providing a designated communication device including a second phone number and a second hardware identification serial number;
• building a connection between said designated communication device and said portable communication device;
• generating a specific command according to said first phone number, said first hardware identification serial number, said second phone number and said second hardware identification serial number, and the generating step further comprises the sub-steps:
• encoding said first phone number and said first hardware identification serial number as a first command by Message-Digest algorithm 5 (MD5);
• encoding said second phone number and said second hardware identification serial number as a second command by Message-Digest algorithm 5 (MD5);
• and
• combining said first command with said second command into said specific command;
• storing said specific command into said portable communication device and said designated communication device;
• waiting for receiving a message;
• determining whether said received message comprises said specific command by comparing said specific command previously stored in said portable communication device with content of said received message;
• and
• performing a protection mechanism for protecting the information stored in said portable communication device when said message comprises said specific command;
• wherein the information stored in said portable communication device is not a command but other data than the command.
