Abstract:

Methods and systems are described for ensuring a high degree of accuracy in the transmission of biometric data (e.g., from a home monitoring device) over a potentially high-noise, error-introducing communication link, such as the Internet, wireless networks, and the telephone system. An intermediate biometric data transmission device is used to receive biometric data from a home monitoring device. The intermediate device encapsulates the raw data packets (which include a checksum) from the home monitoring device in an intermediate data packet with its own checksums. The intermediate device data packet is transmitted over a communication medium to a remote data repository, such as a health data management system. There, the checksums of the intermediate data packet are checked to ensure that the transmission was error free and then the checksums of the original raw biometric data packet are checked using device-specific CRC algorithms stored at the remote system. Thus, two layers of data accuracy checks are made and both are done at the “back end” system rather than at the intermediate device at the home-user end. The high data accuracy may meet standards set for health and medical data transmission over public networks by government agencies and standard-making entities.
