Abstract

An RFID system includes a number of RFID tags and an RFID reader. Each RFID tag includes a respective portion of a target data object. The RFID reader is adapted to read each portion of the target data object from the respective RFID tags. A method of providing an identification function includes using an RFID reader to read one portion of a target data object stored on an RFID tag, from among a number of portions of the target data object stored on a respective number of RFID tags.

Claims

1. An RFID system, comprising:

a plurality of RAD taps; and

a single RFID reader;

wherein each RFID tag of the plurality of RFID tags includes a respective portion of a target data object;

wherein the RFID reader is adapted to read each said portion of the target data object from the respective RFID taps;

wherein the plurality of RFID tags includes first and second RFID taps;

wherein the RFID reader is further adapted to provide a received data object corresponding to the target data object based on first and second portions of the target data object read by the RFID reader;

wherein the RFID reader is adapted to provide the received data object by performing a combination function on at least the first and second portions of the target data object read by the RFID reader; and

wherein the combination function applies a nonlinear invertible shuffler algorithm.

2. The RFID system of claim 1, wherein at least one of first and second portions of the target data object is stored on a respective RFID tag in encrypted form.

3. The RAD system of claim 2, wherein the RFID reader is further adapted to decrypt the at least one of the first and second portions of the target data object.

4. The RFID system of claim 1, wherein a first portion of the target data object is stored on the first RFID tag in a first coded form, and a second portion of the target data object is stored on the second RFID tag in a second coded form.

5. The RFID system of claim 2, wherein the RFID reader is further adapted to read the first portion of the target data object while in a first read mode corresponding to the first coded form, and is further adapted to read the second portion of the target data object while in a second node corresponding to the second coded form.

6. The RFID system of claim 5, wherein the first and second portions of the target data object are stored in mutually-orthogonal coded form, and the RFID reader is adapted to read the first and second portions of the target data object in respective first and second orthogonal polarization-sensitive interrogator modes.

7. The RFID system of claim 1, wherein the first and second RFID tags are disposed on a common substrate.

8. A method of providing an identification function, comprising using a single RFID reader to read one portion of a target data object stored on an RFID tag, wherein the target data object includes a plurality of portions including the one portion, and wherein the plurality of portions includes first and second portions of the target data object, the one portion is a first portion, and the RFID tag is a first RFID tag, further comprising:

using an RFID reader to read a second portion of the target data object stored on a second RFID tag; and

providing received data object corresponding to the target data object based on the first and second portions of the target data object read by the RFID reader;

wherein providing the received data object includes performing a combination function on at least the first and second portions of the target data object read by the RFID reader; and

wherein providing the combination function includes applying a nonlinear invertible shuffler algorithm.

9. The method of claim 8, further comprising decrypting at least encrypted components of the first and second portions of the target data object.

10. The method of claim 8, further comprising reading the first portion of the target data object while in a first read mode corresponding to a first coded form of the first portion of the target data object, and reading the second portion of the target data object while in a second read mode corresponding to a second coded form of the second portion of the target data object.

11. The method of claim 10, wherein the first and second coded forms are mutually-orthogonal coded forms, further comprising reading the first and second portions of the target data object in respective first and second orthogonal polarization-sensitive interrogator modes.

12. The method of claim 8, wherein the first and second RFID tags are disposed on a common substrate.
