Claim:
1. A method for proximity based secure communications, comprising defining a proximity boundary with dimensions defined by a selected communication range of one of a first Short Range Communication (SRC) device and a second SRC device, wherein each of the first and second SRC devices are configured to communicate using near field magnetic induction (NFMI), the first SRC device and a first radio frequency (RF) radio are configured to be coupled to a first mobile computing device and the second SRC device and a second RF radio are configured to be coupled to a second mobile computing device; communicating a proximity signal in the proximity boundary between the first SRC device and the second SRC device, wherein at least one of the first and second SRC devices includes at least two antennas to provide magnetic induction diversity; identifying a data block to be communicated within the proximity boundary; interspersing data in the data block between the first RF radio and the first SRC device of the first mobile computing device for transmission to the second RF radio and the second SRC device, respectively, of the second mobile computing device on a spatially secure NFMI data link and a RF data link; determining a bandwidth ratio of the first RF radio to the first SRC device or the second RF radio to the second SRC device; and interspersing selected data in the data block between the spatially secure NFMI data link and the RF data link, wherein the selected data is interspersed based on the bandwidth ratio.
