Abstract

Systems, methods and computer program products for detecting and re-personalizing are provided herein. In an embodiment, the invention operates by obtaining an ID (i.e., an identification, such as a Dynamic Unique Identifier) from a RFID tag, generating a new ID, and writing the new ID to the RFID tag. The ID read from the tag is used to lookup a subject'"'"'s record in a database. If the write of the new ID to the tag is verified, then database changes are committed to link the new ID to the subject. In an alternative embodiment, the invention operates by obtaining data from a memory of a RFID tag, wherein the memory has a first partition and a second partition, generating a new ID, and writing the new ID to either of the first partition or the second partition of the RFID tag. If such write is verified, then the new ID is written to the other partition of the RFID tag. The data from the tag is used to lookup a subject'"'"'s record in a database. If either write to the first partition or second partition is verified, then database changes are committed to link the new ID to the subject.

Claims

1. A method of detecting and re-personalizing RFID tags, comprising:

obtaining an ID (identification) from a RFID tag;

generating a new ID; and

writing said new ID to said RFID tag.

2. The method of claim 1, further comprising:

using said ID to lookup a subject'"'"'s record in a database;

changing said record to include said new ID to thereby provisionally link said new ID to said subject;

verifying said write of said new ID to said RFID tag; and

committing said change in said database if said write is verified.

3. A system of detecting and re-personalizing RFID tags, comprising:

a database;

a module coupled to said database, wherein said module is configured to;

obtain an ID (identification) from a RFID tag;

generate a new ID; and

write said new ID to said RFID tag.

4. The system of claim 3, wherein said module is further configured to:

use said ID to lookup a subject'"'"'s record in said database;

change said record to include said new ID to thereby provisionally link said new ID to said subject;

verify said write of said new ID to said RFID tag; and

commit said change in said database if said write is verified.

5. A computer program product comprising a computer useable medium having computer program logic recorded thereon for enabling a processor to detect and re-personalize RFID tags, the computer program logic comprising:

means for enabling a processor to obtain an ID (identification) from a RFID tag;

means for enabling a processor to generate a new ID; and

means for enabling a processor to write said new ID to said RFID tag.

6. The computer program product of claim 5, wherein said computer program logic further comprises:

means for enabling a processor to use said ID to lookup a subject'"'"'s record in a database;

means for enabling a processor to change said record to include said new ID to thereby provisionally link said new ID to said subject;

means for enabling a processor to verify said write of said new ID to said RFID tag; and

means for enabling a processor to commit said change in said database if said write is verified.

7. A method of detecting and re-personalizing RFID tags, comprising:

obtaining data from a memory of a RFID tag, wherein said memory has a first partition and a second partition;

generating a new ID; and

writing said new ID to either of said first partition or said second partition of said RFID tag.

8. The method of claim 7, further comprising:

verifying said write of said new ID; and

if said write is verified, then writing said new ID to the other of said first partition and said second partition of said RFID tag.

9. The method of claim 7, further comprising:

determining if contents of said first and second partitions agree;

if said contents agree, then using either contents of said first partition or contents of said second partition to lookup a subject'"'"'s record in a database; and

if said contents disagree, then individually using contents of said first partition and contents of said second partition to lookup a subject'"'"'s record in said database.

10. The method of claim 9, wherein said writing step comprises:

if it is determined that said contents of said first and second partitions disagree, then writing said new ID to one of said first partition and said second partition having bad data stored therein.

11. The method of claim 9, further comprising:

committing database changes to thereby link said new ID to said subject if either said write to said first partition or said write to said second partition is verified.

12. A system of detecting and re-personalizing RFID tags, comprising:

a database;

a module coupled to said database, wherein said module is configured to;

obtain data from a memory of a RFID tag, wherein said memory comprises a first partition and a second partition;

generate a new ID; and

write said new ID to either of said first partition or said second partition of said RFID tag.

13. The system of claim 12, wherein said module is further configured to:

verify said write of said new ID; and

write said new ID to the other of said first partition and said second partition of said RFID tag, if said write is verified.

14. The system of claim 12, wherein said module is further configured to:

determine if contents of said first and second partitions agree;

use either contents of said first partition or contents of said second partition to lookup a subject'"'"'s record in said database, if said contents agree; and

individually use contents of said first partition and contents of said second partition to lookup a subject'"'"'s record in said database, if said contents disagree.

15. The system of claim 14, wherein said module is further configured to:

write said new ID to one of said first partition and said second partition having bad data stored therein, if it is determined that said contents of said first and second partitions disagree.

16. The system of claim 14, wherein said module is further configured to:

commit database changes to thereby link said new ID to said subject if either said write to said first partition or said write to said second partition is verified.

17. A computer program product comprising a computer useable medium having computer program logic recorded thereon for enabling a processor to detect and re-personalize RFID tags, the computer program logic comprising:

means for enabling a processor to obtain data from a memory of a RFID tag, wherein said memory comprises a first partition and a second partition;

means for enabling a processor to generate a new ID; and

means for enabling a processor to write said new ID to either of said first partition or said second partition of said RFID tag.

18. The computer program product of claim 17, wherein said computer program logic further comprises:

means for enabling a processor to verify said write of said new ID; and

means for enabling a processor to write said new ID to the other of said first partition and said second partition of said RFID tag, if said write is verified.

19. The computer program product of claim 17, wherein said computer program logic further comprises:

means for enabling a processor to determine if contents of said first and second partitions agree;

means for enabling a processor to use either contents of said first partition or contents of said second partition to lookup a subject'"'"'s record in a database, if said contents agree; and

means for enabling a processor to individually use contents of said first partition and contents of said second partition to lookup a subject'"'"'s record in said database, if said contents disagree.

20. The computer program product of claim 19, wherein said computer program logic further comprises:

means for enabling a processor to write said new ID to one of said first partition and said second partition having bad data stored therein, if it is determined that said contents of said first and second partitions disagree.

21. The computer program product of claim 19, wherein said computer program logic further comprises:

means for enabling a processor to commit database changes to thereby link said new ID to said subject if either said write to said first partition or said write to said second partition is verified.
