Mobile electronic device, security control method, and security control code

A security control method of a mobile electronic device that includes

• an acceleration sensor configured to detect an acceleration value,
• a first input unit configured to receive input of information enabling unlocking of a security lock state in which a security lock is effective, and
• a second input unit configured to receive input of biological information enabling unlocking of the security lock state,
• the security control method comprising the steps of:
• determining, based on the acceleration value, movement state of user of the mobile electronic device;
• permitting, when it is determined based on the acceleration value that the user is not moving, both unlocking of the security lock state based on information input via the first input unit and unlocking of the security lock state based on information input via the second input unit;
• and
• prohibiting, when it is determined based on the acceleration value that the user is moving, unlocking of the security lock state based on information input via the first input unit and permitting only unlocking of the security lock state based only on information input via the second input unit, wherein
• the state of the user not moving includes movement of the mobile electronic device as a result of the user handling the mobile electronic.

A non-transitory storage medium that stores thereon a security control code for causing a mobile electronic device including an acceleration sensor configured to detect an acceleration value, a first input unit configured to receive input of information enabling unlocking of a security lock state in which a security lock is effective, and a second input unit configured to receive input of biological information enabling unlocking of the security lock state to execute the steps of:

• determining, based on the acceleration value, movement state of user of the mobile electronic device;
• permitting, when it is determined based on the acceleration value that the user is not moving, both unlocking of the security lock state based on information input via the first input unit and unlocking of the security lock state based on information input via the second input unit;
• and
• prohibiting, when it is determined based on the acceleration value that the user is moving, unlocking of the security lock state based on information input via the first input unit and permitting only unlocking of the security lock state based only on information input via the second input unit, wherein
• the movement state in which the user is not moving is a state in which a location of the mobile electronic device has not substantially changed, and
• the movement state in which the user is moving is a state in which a location of the user carrying the mobile electronic device has changed according to time.
