Internet connection. In this embodiment, the network device 300 has a database of a plurality of predetermined images stored in advance, and the network device 300 compares the decrypted images and the predetermined images in the database one by one, and the decrypted images conform to the information database. When a predetermined image is displayed, the user who requests the connection request is a legitimate or recognized user, and the network device 300 allows the portable device 100 to establish a network connection with the network 400. Therefore, the portable device 100 can be connected to a back-end network (such as the Internet) and access data and services on the back-end network. Conversely, it is assumed that the decrypted images are not in compliance with the information library. When a predetermined image indicates that the user who requests the connection request is an illegal or unrecognized user, the network device 300 does not permit the portable device 100 to establish a network connection with the back-end network, and therefore, the portable device The device 100 will not be able to connect to the backend network and will not be able to access the data and services on the backend network. Similarly, in some embodiments, when it is determined that the decrypted image is not a predetermined voucher image, the network device 300 can directly transmit or indirectly transmit a prompt message to the portable device 100 through the wireless access device 200. Notify the user that the network connection failed and ask them to re-operate.
