Abstract

A system and method for enhanced data transfer are disclosed, the method being applicable to a system comprising a computing device configured to transfer data from a portable device. In one embodiment, the computing device stores a fingerprint of the newest record downloaded from a portable device and stops downloading records from the device when a downloaded record matches the fingerprint. In another embodiment, the computing device stores a fingerprint of the newest record downloaded from a portable device and fully processes records that are downloaded from the device after a downloaded record matches the fingerprint. The system may include a portable device configured to adapt its operation responsive to a system fingerprint provided by the computing device. The portable device may be a medical device. The system may be a healthcare data management system.

Claims

1. A method for enhancing data transfers comprising the steps of:

retrieving a last record fingerprint from a computing device;

downloading records from the portable device in sequential order;

comparing each downloaded record to the last record fingerprint to find a match; and

updating the last record fingerprint with the record fingerprint of the newest downloaded record.

2. The method of claim 1 wherein the sequential order is a LIFO order, and wherein no additional records are downloaded after a match is found.

3. The method of claim 1 wherein the sequential order is a LIFO order, further including the steps of selecting previously downloaded records and downloading the selected records;

wherein no additional previously downloaded records are downloaded.

4. The method of claim 1 wherein the sequential order is a FIFO order, further including the step of fully processing records that are downloaded after a match is found.

5. The method of claim 4 further including the steps of selecting previously downloaded records and fully processing the selected records.

6. The method of claim 1 wherein the last record fingerprint is selected from the group consisting of a hash value of a record, an encrypted value of a record, and a record.

7. The method of claim 1 wherein the last record fingerprint is downloaded from the portable device.

8. The method of claim 1 wherein the last record fingerprint is obtained by transforming a record downloaded from the portable device.

9. The method of claim 1 wherein the portable device is a medical device.

10. A system for enhancing data transfers comprising:

a computing device configured to access and download data from a portable device; and

software configured to operate in the computing device and to;

store and retrieve a last record fingerprint;

download records from the portable device in sequential order;

compare each downloaded record to the last record fingerprint to find a match; and

update the last record fingerprint with the record fingerprint of the newest downloaded record.

11. The system of claim 10 wherein the software is further configured to generate a last record fingerprint.

12. The system of claim 11 wherein the last record fingerprint is selected from the group consisting of a hash value of a record, an encrypted value of a record, and a record.

13. The system of claim 10 wherein the software is healthcare data management software and the portable device is a medical device.

14. A data management system for enhancing data transfers comprising:

a computing device;

data management software configured operate in the computing device and to upload a system fingerprint to a portable device; and

a portable device configured record data in records, to receive the system fingerprint from the data management software, and to adapt its operation based on a relationship between the system fingerprint and the portable device records.

15. The system of claim 14 where the adaptation is responsive to a code encoded in the system fingerprint.

16. The system of claim 14 where the adaptation consists of preventing deletion of portable device records not yet downloaded to the data management software.

17. The system of claim 14 where the adaptation consists of selecting and downloading portable device records based on the type of data management system accessible to the portable device.

18. The system of claim 14 wherein the system fingerprint comprises a system identifier.

19. The system of claim 14 wherein the system fingerprint comprises a last record fingerprint and a system identifier.

20. The system of claim 14 wherein the system fingerprint comprises a type of healthcare data management system.

21. The system of claim 14 wherein the data management software is healthcare data management software.

22. The system of claim 14 wherein the data management software is diabetes management software.

23. The system of claim 14 wherein the portable device is a medical device.

24. A method for enhancing data transfers comprising:

uploading a system fingerprint from a data management software to a portable device; and

adapting the operation of the portable device based on content of the system fingerprint.
