摘要:
An augmented reality (AR) service including a photographing unit to capture an image of a target object, an information collecting unit to collect contextual information of the captured image of the target object, a tag generating unit to generate an AR tag of a first direction, the AR tag corresponding to the contextual information, and a display unit to display the image of the target object and the AR tag. A method for providing an AR service including capturing an image of a target object with a camera, collecting contextual information including location information of the captured image of the target object and a first azimuth information between the target object and the camera, generating an AR tag corresponding to the contextual information, and displaying the captured image of the target object and the generated AR tag.
摘要:
A user equipment to generate augmented reality (AR) tag information includes a photographing unit to capture an image of a target object, an information collecting unit to collect contextual information when the photographing unit captures the image of the target object, and a control unit to generate AR tag information of the target object based on the contextual information. A method for generating AR tag information in a user equipment includes capturing an image of a target object, collecting contextual information when capturing the image of the target object, and generating AR tag information of the target object based on the contextual information.
摘要:
A method and apparatus for secure communication between a client and a server are provided. In the method, in order to enable communication between the client and the server, a session key is managed according to session identification information corresponding to the session key, and if there is a valid session key, data is encrypted or decrypted using the session key. If there is no valid session key, the client generates a new session key, operations for enabling application programs executed on one client to share a single session key are performed, so that secure communication is performed using the session key.
