Abstract

A system and method for encoding and decoding data. A method includes selecting a subgroup of bits from one or more bytes of binary encrypted information, wherein the binary encrypted information is for tracking, locating, and disabling an electronic device; passing the subgroup of bits to an encoding function that performs binary mapping operations on the subgroup of bits to generate an encoded byte; and encoding the next one or more bytes of binary encrypted information if the end of the binary encrypted information has not been reached.

Claims

1. A method of encoding data, comprising:

selecting a subgroup of bits from one or more bytes of binary encrypted information, wherein the binary encrypted information is for tracking, locating, and disabling an electronic device;

passing the subgroup of bits to an encoding function that performs binary mapping operations on the subgroup of bits to generate an encoded byte; and

encoding the next one or more bytes of binary encrypted information if the end of the binary encrypted information has not been reached.

2. The method of claim 1, wherein the binary encrypted query information is encoded into American Standard Code of Information Interchange text format.

3. The method of claim 1, wherein the binary mapping operations further comprises mapping of the subgroup of bits to a character that may be printed and displayed.

4. The method of claim 3, wherein every three bytes of binary encrypted information is mapped to four bytes of encoded data.

5. The method of claim 1, wherein the subgroup of bits is six bits.

6. The method of claim 1, further comprising:

storing the one or more bytes of binary encrypted information in a first variable, wherein each byte of data is made up of bits;

storing the subgroup of bits from the one or more bytes of data in a second variable; and

storing the encoded byte into a data structure.

7. The method of claim 6, wherein the data structure is an array of bytes.

8. A method of decoding data, comprising:

selecting a byte of American Standard Code of Information Interchange text format information, wherein the American Standard Code of Information Interchange text format information byte is for tracking, locating, and disabling an electronic device;

passing the byte to a decoding function that returns a decoded byte;

extracting the lower six bits of the decoded byte and discarding the upper two bits, wherein the lower six bits are appended to a stream of bits that form consecutive bytes; and

decoding the next bytes of data from the American Standard Code of Information Interchange text format information if the end of the American Standard Code of Information Interchange text format information has not been reached.

9. The method of claim 8, wherein the decoding function further comprises mapping the byte of American Standard Code of Information Interchange text format information to the binary format query information data byte.

10. The method of claim 8, further comprising storing the consecutive bytes into a data structure.

11. The method of claim 10, wherein the data structure is an array of bytes.

12. A machine-readable medium that provides instructions, which when executed by a machine, cause said machine to perform operations comprising:

selecting a subgroup of bits from one or more bytes of binary encrypted information, wherein the binary encrypted information is for tracking, locating, and disabling an electronic device;

passing the subgroup of bits to an encoding function that performs binary mapping operations on the subgroup of bits to generate an encoded byte; and

encoding the next one or more bytes of binary encrypted information if the end of the binary encrypted information has not been reached.

13. The machine-readable medium of claim 12, wherein the binary encrypted query information is encoded into American Standard Code of Information Interchange text format.

14. The machine-readable medium of claim 12, wherein the binary mapping operations further comprises mapping of the subgroup of bits to a character that may be printed and displayed.

15. The machine-readable medium of claim 14, wherein every three bytes of binary encrypted information is mapped to four bytes of encoded data.

16. The machine-readable medium of claim 12, wherein the subgroup of bits is six bits.

17. The machine-readable medium of claim 12, further comprising:

storing the one or more bytes of binary encrypted information in a first variable, wherein each byte of data is made up of bits;

storing the subgroup of bits from the one or more bytes of data in a second variable; and

storing the encoded byte into a data structure.

18. The machine-readable medium of claim 17, wherein the data structure is an array of bytes.

19. A machine-readable medium that provides instructions, which when executed by a machine, cause said machine to perform operations comprising:

selecting a byte of American Standard Code of Information Interchange text format information, wherein the American Standard Code of Information Interchange text format information byte is for tracking, locating, and disabling an electronic device;

passing the byte to a decoding function that returns a decoded byte;

extracting the lower six bits of the decoded byte and discarding the upper two bits, wherein the lower six bits are appended to a stream of bits that form consecutive bytes; and

decoding the next bytes of data from the American Standard Code of Information Interchange text format information if the end of the American Standard Code of Information Interchange text format information has not been reached.

20. The machine-readable medium of claim 19, wherein the decoding function further comprises mapping the byte of American Standard Code of Information Interchange text format information to the binary format query information data byte.

21. The machine-readable medium of claim 19, further comprising storing the consecutive bytes into a data structure.

22. The machine-readable medium of claim 21, wherein the data structure is an array of bytes.
