Abstract: The invention prevents data from leaking. In a data management system (1), a terminal device (2) saves a remaining data among the remaining data and an incomplete data acquired by partitioning an image data of an ID card of a user in a storage unit, and uploads the incomplete data to a data management server (5) via a network (N). A data recovery device (4) acquires the remaining data from the terminal device (2), and acquires the incomplete data from the data management server (5) via the network (N). Further, the data recovery device (4) recovers the image data of the ID card of the user from the remaining data and the incomplete data.

Abstract: In an authentication system, a mobile communication client transmits to an authentication server a bit signal that includes an image capture bit sequence obtained by capturing an image of a self-aware two-dimensional code having authentication information embedded in a correction area, and a number bit sequence that indicates a serial number of an authentication application program being stored in storage. The authentication server authenticates the user of the mobile communication client and the self-aware two-dimensional code. Subsequently, the authentication server transmits designated information expressed by the self-aware two-dimensional code to the mobile communication client, on the condition that the user and the self-aware two-dimensional code are successfully authenticated. Consequently, the mobile communication client is able to acquire the designated information expressed by the self-aware two-dimensional code.
