Abstract: The present invention provides a treatment method for doorbell communication in order to save the data bandwidth of video streaming communication. The structure of doorbell communication according to the present invention comprises a doorbell, a camera and a microphone, which are connected with a smart phone and a server of a home by a network. When a user pushes the doorbell, the camera captures the face image of the user, and then sends to the server for face recognition. If the face image of the user matches with one of the face templates stored in the server, then the personal data of the related face template is shown on the screen of the smart phone for conducting audio streaming communication without video streaming communication.

Abstract: The present invention provides a method for householder of mansion to manage entrance by smart phone, so that the householder can manage entrance at outside. When a visitor pushes a doorbell of a mansion door machine, the householder at outside uses a smart phone to conduct audio and video communication with the visitor. If the householder agrees to let the visitor go in, the householder instructs the smart phone to generate a password for the visitor to memorize and let the visitor enter the mansion. The password is also sent to a home door machine of the householder. When the visitor an ives the home door machine of the householder, input the password. If the password inputted by the visitor is the same as the password generated by the smart phone, then the home door will open to let the visitor go in.

Abstract: The present invention provides a monitor for dynamic displaying. K cameras are connected with the monitor in order to display images recorded by the k cameras on a screen of the monitor. An “abnormality detection algorithm” is used for detecting abnormalities of the images recorded by the k cameras. Those images having abnormalities are displayed continuously on the screen, other images having no abnormality are not displayed, so that a security service personnel can watch those images having abnormalities on the screen to enable appropriate action quickly.

Abstract: The present invention provides a method of preventing pry for random access memory. A functional interface is designed between a computer program and a random access memory. When the computer program wants to store an original data into the random access memory, an encryption procedure is processed on the original data first, and then stoic into the random access memory for being an encrypted data. When the computer program ants to fetch related data float the random access memory, the functional interface is used to fetch the encrypted data for decryption, so that the original data is obtained for calculation.

Abstract: The present invention provides a registration method for managing NAT shutdown. In Internet communication field, a user must perform registrations intermittently to a server through NAT, and increase the time interval of registration step by step. But NAT itself will shutdown if no packet is passed through for a long period. The registration method of the present invention is to adjust the time interval of registration step by step so that the time interval of registration is slightly less than the shutdown time of NAT, and then fix the time interval of registration to assure that all of the Invite packet can pass through without blocking up by the shutdown of NAT.

Abstract: The present invention provides a method of searching for multimedia image. When a camera and a microphone are used for recording an image file, a software of speech recognition is used for converting the speech recorded by the microphone into a text file, and then the image file and the text file are combined to form a folder for storing into a data base. If a user wants to search for a certain image file, the data base is entered to search all folders, and a key word is used for searching the related text files so that the related image files are very easy to find.

Abstract: The present invention provides a method of image conversion operation for panorama dynamic IP camera. Three wide-angle cameras are used for obtaining a panorama dynamic image, and then to be compressed and transferred through Internet to a PC/smartphone/tablet for being decompressed and image conversion operation, so that a user can use the PC/smart phone/tablet to slide a touch screen thereof for viewing the desired dynamic image.

Abstract: The calculation for DFT(Discrete Fourier Transform) is too much in prior art, so the present invention provides a new method DMFT(Discrete Multi-Frequency Transform) for calculation. For example, in prior art, to determine a DTMF signal “3”, the calculation must be performed for k=96˜92 (frequency 1477 Hz with tolerance ±2.5%) and k=45˜43 (frequency 697 Hz with tolerance ±2.5%), total 8 of X[k] value have to be calculated, but the present invention performs a single calculation of X[k] for each frequency. To determine a DTMF signal “3”, only a high frequency of X[k] and a low frequency of X[k] are required to calculate.

Abstract: The present invention provides a toning control method for setting a WiFi device by a smart device so that the WiFi device can link with Internet through a WiFi AP. The present invention is different from the prior art that a smart phone uses WiFi signal to set an IP camera, and is also different from the prior art that a smart phone generates QR Code for setting an IP camera. The present invention adopts methods of DTMF (Dual-Tone Multi-Frequency) or FSK (Frequency-Shift Keying) for toning encoding, and sends the toning encoding through a loudspeaker of the smart device to a toning decoder of the WiFi device for toning decoding, then performs the setting and linking of the WiFi device.

Abstract: The present invention provides VoIP authentication in 4G VoLTE, and also provides an extra authentication method of VoLTE for achieving communication security. The key point of the extra authentication method of VoLTE is: when a 4G mobile phone is turned on for the first time, a security registration sequence number will be random generated by the 4G mobile phone, and sent with IMSI and IMEI through TLS to an account assignment server for comparison and storage. Thereafter the account assignment server sends an account and a password in a database corresponding to IMSI to the 4G mobile phone, and then the 4G mobile phone conducts VoIP authentication with a SIP server for standby or communication.

Abstract: In SIP network environment, a general NAT traversal method will become invalid when an NAT with ICMP (Internet Control Message Protocol) is met. The present invention provides four sessions for SIP, i.e. Login Session, Port Prediction Session, Synchronization Session and Media Session, and the SIP network environment includes a first Internet telephone, a second Internet telephone, a first symmetric NAT, a second symmetric NAT and an SIP proxy server. The first symmetric NAT and the second symmetric NAT are ICMP-sensitive. In the Synchronization Session, the first Internet telephone and the second Internet telephone are designed to transmit packets synchronously to avoid port locking.

Abstract: In SIP network environment, a general traversal method for a port restricted NAT will become invalid when other users break in. The present invention provides four sessions for SIP, i.e. Login Session, Port Prediction Session, Multi-Traversal Session and Media Session, and the SIP network environment includes a first Internet telephone, a second Internet telephone, a symmetric NAT, a port-restricted NAT and an SIP proxy server. In the Multi-Traversal Session, the second Internet telephone sends a plurality of identical speech packets to consecutive ports of the symmetric NAT through a fixed port of the port-restricted NAT so as to achieve the NAT traversal.
