Simple authentication checks have different forms: the key may be a password memorized by the user, it can be physical or digital objects, belonging to the user, it can be a unique biological characteristics. Simple authentication systems are considered 'Open', as if the key is transmitted over the network, it can be intercepted by an attacker. There are reports of successful passive attacks in the Internet using the "split" is already a computer CERT94. Disclosing authentication mechanisms are vulnerable to attack "play." Access keys can be stored in the target machine, and in the presence of a security breach can access all the passwords. Typically, the storage form of passwords allows them to reconcile, but not reading.

There will be a function of the group photo, the camera will determine not only one person, it helps to make higher-quality picture with a large number of people in the frame. Most likely, the standard will be the mode of recognition scene, ie the camera itself will analyze the space frame, taking into account the brightness and contrast of the object, focusing distance and the background, and then will select the optimal settings the picture. Also, cameras will to support more formats, including support for recording high-definition video (720p) and the presence hdmi output for viewing on your tv directly from the camera.
