Abstract:
In the last decade, there has been a widespread use of autonomous robots in several application fields, such as
border controls, precision agriculture, and military operations. Usually, in the latter, there is the need to encrypt
the acquired data, or to mark as relevant some positions or areas. In this paper, we present a client-server rover-based
system able to search encrypted targets within an unknown environment. The system uses a rover to
explore an unknown environment through a Simultaneous Localization And Mapping (SLAM) algorithm and
acquires the scene with a standard RGB camera. Then, by using visual cryptography, it is possible to encrypt
the acquired RGB data and to send it to a server, which decrypts the data and checks if it contains a target
object. The experiments performed on several objects show the effectiveness of the proposed system.
