Abstract: An identity authentication device includes a communication unit configured to establish communication with a plurality of online servers, a processor, and a storage configured to store a user profile database including a number of user profiles, wherein each of the user profiles corresponds to an online browsing habit. The processor receives an online browsing record of a user, compares the received online browsing record to the online browsing habits of the user profiles stored in the user profile database to determine whether the received online browsing record matches one of the online browsing habits, and determines whether the received online browsing record belongs to a same user of a matched one of the user profiles according to a result of comparison.

Abstract: An advertising device obtains chat information during a chat session of a user, obtains keyword information from the chat information, searches for matching advertisements from a database according to the keyword information, and provides the matching advertisement when an interface of the chat session is changed to an interface allowing an advertisement when the matching advertisement has been obtained. When no matching advertisement has been obtained according to the keyword information, a preselected advertisement is provided.

Abstract: A method for processing text messages includes receiving a text message and recording sender information. Data as to individual voice of the sender is searched for in a voice synthesis database and the text message is converted to a voice message using the data of individual voice. The voice message is then played. The application further discloses a text message processing device in which the text message processing method is applied.

Abstract: A method for identifying and associating information with particular individuals to render same sufficient for registration and login purposes by a specific individual, used in an identity information matching system, includes identifying individuals in scene, recording voices in the scene, identifying individual voices and words and semantics used, and determining an action from a target individual given in response to a trigger voice emanating from the individual voices. The trigger voice and words and semantics associated with the responding target individual are recorded. An identity information matching system and a user device processing the identity information matching method are also disclosed.

Abstract: An electronic device and a method therefor is applied to controlling a display. The method includes acquiring control operations of a user and determining that a first control instruction has been given according to relationship between predetermined control operations and control instructions stored in a storage device. Method also determines whether such first control instruction requires a switch to be made according to a predetermined condition. Upon determining that the control operations satisfy the predetermined condition and that a switch in instruction is required, switching to a second instruction in place of the first instruction according to the predetermined instruction switching rule of the state switching device in a current state. A function corresponding to the second control instruction is activated in place of the first instruction if the state-switch is to be made.

Abstract: A remote encryption method is executed by at least one processor of a cryptographic center. The cryptographic center connects to a sending end and to at least one receiving end. Data and a list listing at least one receiving end to which the data is to be sent are received from the sending end. A public key corresponding to the at least one receiving end listed in the received list is obtained. The received data is asymmetrically encrypted using the obtained public key corresponding to the at least one receiving end. The encrypted data is sent to the corresponding receiving end.

Abstract: Photographic equipment, which is capable of electrically connecting to an electronic device, including: a rod body; a fixing device used to fix the electronic device, which is attached to a first end of the rod body; a communication interface used to electrically connect to the electronic device to enable communication between the photographic equipment and the electronic device; a screen located on the rod body, and used for previewing an image taken by a camera of the electronic device; and a control unit attached to a second end of the rod body, which is operable to control the electronic device and the photographic equipment.

Abstract: A key generation device generates an initial secret key, and a time update key at regular intervals, and transmits the initial secret key and the time update key to a terminal device. The terminal device utilizes the initial secret key, the time update key, and a private key generated by the terminal device itself to form a key group. The key group and a public key generated by the terminal device are used as a key pair to encrypt and decrypt data, give a digital signature, and verify digital signatures. The time update key includes a time period, and after the time period expires the time update key cannot be used by the terminal device to generate the key group. A data signature and encryption method is also provided.

Abstract: A method for controlling illumination of an object being photographed includes generating and sending an invitation signal to a number of secondary electronic devices to join a group for photographing the object, generating and sending a photosensing signal to each of the secondary electronic devices in the group to detect an illumination value of the object, focusing an image of the object and detecting an illumination value of the object, detecting a distance value between the object and the primary electronic device, detecting a distance value between the object and each of the secondary electronic devices, and calculating a required flash driving current and a required flash duration of the primary electronic device and each of the secondary electronic devices and a required exposure time for photographing the object. The object is photographed by the first electronic device.

Abstract: A data encrypting and decrypting method which functions in an electronic device is activated when an application program is activated in the device. Data arising from user input is generated and a public and private key pair is also generated. The data is encrypted with the public key to obtain cryptographs and the cryptographs are sent to the application program. The method allows for decryption of the cryptographs with the private key to obtain the original data.
