The disclosure is related to monitoring data traffic of user equipment through a monitoring node. A monitoring node may receive a data packet from user equipment registered for a monitoring service through a secure channel. The monitoring node may perform a monitoring operation on the received data packet and determine whether the received data packet is a malicious packet or a non-malicious packet. When the received data packet is a non-malicious packet, the monitoring node may transmit the data packet to a destination through a communication network.

Method and apparatus for measuring sizes of objects by using photograph. Method includes taking photograph by using camera; recognizing reference scale in photograph and measuring size of reference scale; measuring vertical direction angle and horizontal direction angle between the camera and the objects by using image properties of the recognized reference scale; recognizing the objects in the photograph and measuring vertical sizes and horizontal sizes of the objects; and acquiring actual vertical sizes and actual horizontal sizes of the objects by compensating the measured vertical size and the measured horizontal size of the objects based on the size of the reference scale, the actual size of the reference scale, and the vertical and horizontal direction angles. Therefore, heights and widths of objects distributed throughout a wide area may be precisely measured regardless of positions of the objects by using a reference scale for comparatively measuring sizes of the objects.
