Abstract: A communication component sends a request of an action list to a server if information fails to pass authentication. A control component processes content stored in an electronic device according to a reply generated in response to the request. The reply includes the action list. The processing is performed according to an action included in the action list.

Abstract: A virtual camera component allows multiple camera-use applications to share a camera simultaneously. For example, a first application can request access to the camera for a first set of data, and a second application can also request access to the camera for a second set of data. The virtual camera component is coupled between the first and second applications and the camera, and caches and then processes the data according to respective requirements of the first and second applications.

Abstract: A credential provider component receives predetermined identity information (IDINF) from a portable device and controls an information database to provide a predetermined credential if the predetermined IDINF matches content in the information database. A log-on component allows the portable device to log on to a network device using the predetermined credential if the predetermined credential is valid.

Abstract: A key for a user can be created according to at least one first image of the user. The key can be verified with at least one second image of the user captured after the key is created. A visitor can be authenticated according to a first measure of similarity between the key and at least one authentication image of the visitor. The visitor is authenticated as the user if the first measure of similarity is greater than a first predetermined threshold. The key can be refined with the at least one authentication image of the visitor if the first measure of similarity is lower than the first predetermined threshold and the visitor is authenticated as the user based on a password.

Abstract: A system for providing computer services includes a camera and an electronic device. The camera obtains recognition information for a user. The electronic device is operable for executing a first operating system for conducting user authentication according to the recognition information and for automatically operating a user-defined application program after the user passes said user authentication.
