Abstract

In accordance with at least one embodiment of the present invention, a portable inspection system is configured to capture inspection data, such as for example an infrared image. The inspection data is securely recorded (e.g., with an encryption algorithm) along with associated information, which may include for example date, time, system settings, operator identification, and location.

Claims

1. An infrared camera system comprising:

an infrared camera adapted to capture image data of a target; and

a processor adapted to provide a signature for the image data and associated information, wherein the associated information provides at least one of a location of the infrared camera, an orientation of the infrared camera, operator information of the infrared camera, a time of the image data capture, a date of the image data capture, camera settings, and target information.

2. The infrared camera system of claim 1, wherein watermark information is inserted into at least one of the image data, the associated information, and a header for the image data by at least one of the infrared camera and the processor.

3. The infrared camera system of claim 1, further comprising a target identification unit adapted to obtain the target information of the target, wherein the target identification unit comprises at least one of an RFID reader and a barcode reader.

4. The infrared camera system of claim 1, wherein the processor encrypts at least one of the image data and the associated information by executing an encryption algorithm comprising at least one of an RSA algorithm, a DES algorithm, an AES algorithm, an SHA algorithm, and an MD algorithm.

5. The infrared camera system of claim 1, wherein the processor provides the signature for the image data and the associated information by hashing the image data and the associated information and signing with a private key to generate a cryptographic signature.

6. The infrared camera system of claim 1, further comprising a position determination unit adapted to obtain at least the location of the infrared camera and the orientation of the infrared camera.

7. The infrared camera system of claim 1, further comprising an operator identification unit adapted to obtain the operator information of the infrared camera, wherein the operator information comprises at least one of a fingerprint and an eye scan.

8. The infrared camera system of claim 1, further comprising a timekeeping unit adapted to provide at least one of the time and the date of the image data capture.

9. The infrared camera system of claim 1, further comprising an input/output interface adapted to provide the image data along with the associated information.

10. A portable inspection system comprising:

means for inspecting a target to obtain inspection data;

means for obtaining a first set of information associated with the inspection data, wherein the first set of information comprises at least one of a setting of the inspecting means, a location of the inspecting means, an orientation of the inspecting means, operator information of the inspecting means, a time of obtaining the inspection data, a date of obtaining the inspection data, and target information; and

means for generating a signature for the inspection data and the first set of information associated with the inspection data.

11. The portable inspection system of claim 10, wherein the inspecting means comprises at least one of an infrared camera, an ultrasonic analysis system, a vibration analyzer, and a lubrication analyzer.

12. The portable inspection system of claim 10, further comprising means for watermarking at least one of the inspection data, the first set of information, and a header for the inspection data.

13. The portable inspection system of claim 10, wherein the generating means generates a cryptographic signature for the inspection data and the first set of information associated with the inspection data.

14. The portable inspection system of claim 10, further comprising means for providing the inspection data and the first set of information associated with the inspection data from the inspection system.

15. The portable inspection system of claim 10, further comprising downloading the inspection data and the first set of information associated with the inspection data based on the first set of information.

16. A method of securely recording inspection data within a portable inspection system, the method comprising:

inspecting a target with the inspection system to obtain inspection data;

determining at least one of target information and a location of the inspection system during the inspecting operation;

determining a time and a date for the inspecting operation; and

securing the inspection data, the time, the date, and at least one of the location and the target information within the inspection system with an encryption algorithm.

17. The method of claim 16, wherein the inspection system comprises at least one of an infrared camera, an ultrasonic analysis system, a vibration analyzer, and a lubrication analyzer.

18. The method of claim 17, further comprising:

determining a setting of the inspection system; and
