Abstract

Methods and system of securing content and a destination of downloaded data may include a remote server comprising an executable file generator module operable to generate a customized file comprising requested map information and a data marker locking the map information to a predetermined end user device. The file generator module is further operable to encrypt the data marker and place a cipher key at a predetermined location in the customized file. The remote server is further operable to provide a download link to a user operating a user computing device operable to download the customized file from the remote server, for subsequent transfer to an end user device. Based upon the contents of the data marker, the end user device is operable to determine whether the downloaded file is intended for that particular end user device.

Claims

1. A method of securing content and destination of downloaded data, comprising the steps of:

logging a user into a remote system;

generating on the remote system a data marker including an identification number of a user device;

generating on the remote system a customized file comprising the generated data marker and a user selected information file;

providing a download link to the user; and

downloading the customized file.

2. The method of claim 1, further comprising:

checking that the logged on user has purchased the selected information file and that the user has registered the user device with the identification number provided;

encrypting the data marker and inserting a cipher key, operable to decrypt the encrypted data marker, in the customized file at a predetermined location.

3. The method of claim 1, wherein the information data is map information and the method further comprising:

presenting to the user a list of available maps based upon a selected registered user device;

retrieving a list of devices that the user has registered; and

registering a different device or choosing a previously registered device.

4. The method of claim 2, wherein the data marker is 64 bytes.

5. The method of claim 1, wherein generating a data marker comprises generating a data marker including a security version identifier, a security flag, and a validity date.

6. The method of claim 5, wherein the data marker includes an unlock code.

7. The method of claim 1, further comprising:

receiving the customized file at a computing device across a network; and

transferring the customized file from the computing device to an electrically connected GPS device.

8. The method of claim 1, wherein a portion of the data marker identifies a provider of the data and a data ID provides a unique identifier for each type/set of data from each vendor.

9. The method of claim 1, wherein a portion of the data marker identifies a particular type of data from a given vendor.

10. The method of claim 1, wherein a portion of the data marker identifies a date the data marker becomes invalid.

11. The method of claim 1, wherein a portion of the data marker identifies a unique media that the customized file is meant to reside on.

12. The method of claim 11, wherein the portion of the data maker which identifies the unique media would either be derived from a secure digital (SD) card ID or the end user device identification number.

13. At least one processor configured to perform the actions of:

logging a user into a remote system comprising a map server;

generating on the map server a data marker including an end user device identification number for the end user device;

generating on the map server a customized file comprising the generated data marker and a user selected map file;

providing a download link for the user; and

downloading the customized file.

14. A method of securing content and destination of downloaded data, comprising the steps of:

receiving on a portable end user device a customized file from a computing device across a network, the customized file comprising user selected information and a data marker including information pertaining to a specific end user device;

comparing the information stored in the data marker block with at least a serial number of the end user device; and

utilizing the user selected information on the end user device based upon a result of the comparison.

15. The method of claim 14, further comprising:

extracting a cipher key from a predetermined location within the customized file; and

decrypting the data marker using the extracted cipher key.

16. The method of claim 14, wherein comparing information stored in a data marker within the customized file includes comparing a serial number of the end user device with a target Unit ID field of the data marker.

17. The method of claim 14, wherein utilizing the user selected information on the end user device is based upon a set of rules specified in the data marker.

18. A portable GPS device configured to perform the actions of:

receiving a customized map file from a computing device, the map file comprising map information;

comparing information stored in a data marker block of the customized map file with at least a serial number of the GPS device in order to determine that the received customized map file is intended for the GPS device receiving the map; and

displaying the map information on the GPS device based upon a result of the comparison.
