The invention provides an unlocking method, system and device of a mobile terminal. The unlocking method includes the following steps that a user arranges cloud terminal unlocking authentication information of the mobile terminal to a remote server; an unlocking interface of the mobile terminal provides a cloud terminal unlocking icon; when the cloud terminal unlocking icon is triggered, the mobile terminal starts network connection and prompts a user to input authentication information. The mobile terminal sends the authentication information input by the user to a remote-control server. The remote-control server judges whether the authentication information is matched with the cloud terminal unlocking authentication information or not. If judgment is matched, the remote server returns successful authentication information to the mobile terminal and the mobile terminal performs unlocking according to the successful authentication information. According to the unlocking method, system and device of the mobile terminal, the cloud terminal unlocking authentication information is stored at the cloud terminal, by inputting the self-set cloud terminal unlocking authentication information, a user who forgets a password can unlock. The unlocking method, system and device of the mobile terminal is easy to operate, convenient to use, and capable of rapidly unlocking and meanwhile, improving intelligence of the terminal.

The invention discloses a method for accessing a smart home, control center equipment and a wearing terminal. The method comprises the steps of accessing a local terminal by a remote terminal, transmitting an encrypted authentication digital fingerprint sent by the wearing terminal to the control center equipment by means of the remote terminal, receiving the encrypted authentication digital fingerprint by means of the control center equipment, decrypting the encrypted authentication digital fingerprint according to stored keys, matching the decrypted authentication digital fingerprint with a pre-stored initial digital fingerprint, and enabling the remote terminal to access and control the local terminal after the successful matching step. According to the technical scheme of the invention, the smart home accessing safety is improved.

Method for accessing smart home, control center equipment and wearing terminal

The invention provides a method for automatically having access to the network. The method includes the steps that a server terminal starts a UDP to conduct broadcasting and sends a UDP information packet; a client terminal receives the UDP information packet and obtains the IP address of a server from the UDP information packet; according to the IP address of the server, TCP network connecting is built. By means of the method for automatically having access to the network, positive registering, reconnection after offline and intelligent heartbeats are achieved.

Method for automatically having access to network

The invention discloses a method for encrypting and decrypting multimedia-media data, comprising the following steps: step1, setting an encrypting/decrypting key, wherein the length of the encrypting/decrypting key is N; step 2, encrypting, which is to obtain the key data of the front N-bite byte of a multimedia file, execute the exclusive-or calculation for each bite of the key data with the encrypting key, and restore the data after being encrypted to the front N-bite byte of the multimedia file; and step 3, decrypting, which is to obtain the key data of the front N-bite byte of the encrypted multimedia file, execute the exclusive-or calculation for each bite of the key data with the decrypting key, write the calculation result data in the region of the front N-bite byte of the multimedia file, then store the data, and revert to obtain the original file of the multimedia file.

Method for encrypting and decrypting multimedia-media data

The invention discloses a method and a system for authenticating identities of a remote network on the basis of multi-biometric features, the system comprises a multi-biometric features network sampling and controlling terminal, the remote network and a central authenticating server, the method comprises building communication connections by the multi-biometric features network sampling and controlling terminal and the central authenticating server, obtaining biometric features data through a biometric features sampling module, encrypting the biometric features data through a communication module, then, transferring to the central authenticating server through the remote network according to a TCP/IP protocol, matching the biometric features data with the biometric features data which is stored in the server by the central authenticating server to authenticate identities of biometric features holders, and sending control orders to the multi-biometric features network sampling and controlling terminal according to authenticating results. The invention enables a computer to be connected with a plurality of sampling equipment which is provided with biometric features as fingerprints,human faces, irises and retinas through the remote network in a mode of the central authenticating server.

The invention relates to a method for binding and publishing digital information on the basis of the fingerprint field, the method can safely bind fingerprint information with the digital information or a secret key to achieve the aim of protecting the fingerprint information and the digital information doubly, and simultaneously fingerprint identity validation is adopted to guarantee the legal access to the digital information or the secret key. The realized method of the invention comprises: firstly, encrypting, namely, using error correcting codes to abstract frequency domain information of registered fingerprints and carry out binary coding for the digital information or the key, binding the fingerprint information after the binary coding and the digital information or the key after the error correcting codes or storing the digital information or the hash value of the secret key and the data after binding, secondly, decoding, namely, abstracting the frequency domain information ofcomparison fingerprints and carrying out the binary coding, and operating the fingerprint data after the binary coding and bond data, and obtaining the digital information or the secret key through the error correcting codes, decryption is successful if the digital information or the hash value of the secret key is the same with the hash value which is preserved before, and otherwise the decryption is failed.

Method for binding and publishing digital information or cryptographic key based on fingerprint frequency domain

The utility model discloses a telenet identity authenticating system which is based on the multi-biometric character. The system includes a multi-biometric character network collecting and controlling terminal, a telenet, and a central authenticating server. The multi-biometric character network collecting and controlling terminal establishes a communication connection with the central authenticating server, acquires the biometric character data by a biometric character collecting module, and transfers the biometric character data to the central authenticating server through the communication module in the TCP/IP protocol. The central authenticating server matches the biometric character data with the biometric character data which is stored in the server in order to authenticate the identity of the biometric character holder, and sends control instruction to the multi-biometric character network collecting and controlling terminal according to the authenticated result. The utility model enables a computer to be connected to a fingerprint, face, iris, and retina multi-biometric character collecting device through the telenet in the method of the central authenticating server.
