An automated monitoring service downloads image files and audio files from various Internet sites, and checks these files for the presence of embedded digital watermark data. Electrodes are placed into the soil both outside the structure and through the structure’s foundation. To restrict software, a restricted access token may be computed that reduces software’s access to resources, andor removes privileges, relative to a user’s normal access token. Moreover, the routing component can automatically and seamlessly employ an optimized communication session utilizing the dynamically identified optimized data communication mode based upon an activation of the virtual contact identifier. An antenna diversity module measures at least one of an average signal to noise ratio and an error rate of said data packets during at least one of transmitting and receiving N packets, where N is an integer greater than one, and selects one of said at least two antennas based on said at least one of said average SNR and said error rate. The liquid crystal layer is located between the upper component and the lower component.
