Abstract: A method of dynamically generating a security question for accessing a resource. The method comprises monitoring a behavior of said user during a monitoring period to identify automatically a deviation from a behavioral pattern indicative of repetitive behavior of a user, automatically generating a security question responded to by an indication of said deviation, receiving a user input inputted by a user in response to a presentation of said security question and said deviation, and authenticating, after said monitoring period, an access to a resource according to a match between said user input and said deviation.

Abstract: A method of decrypting an encrypted message. The method comprises storing a wearer decryption code in a memory of a wearable mobile device having a head-worn augmented display which generates an augmented reality view for a wearer of the wearable mobile device, capturing using the wearable mobile device a video sequence including at least one frame imaging a visible code using an image sensor of the wearable mobile device, processing the video sequence to identify the visible code, decrypting the visible code using the wearer decryption code to create an decrypted content, and presenting the decrypted content on top of at least some of the visible code in the augmented reality view.

Abstract: A method of creating a video sequence. The method comprises setting at least one repetitive reminder in a schedule managed by a handheld device having an image sensor, alarming a user according to the at least one repetitive reminder, capturing a sequence of images using the image sensor, automatically identifying a facial image depicting a face in a preset area in the sequence of images, automatically selecting the facial image, in response to the identification, and adding the facial image to a facial video sequence.
