Abstract

A method and system for secure package delivery utilizing digital signatures is described. In one configuration, data regarding the weight, dimensions and origination are cryptographically processed to create an authentication digital signature with message retrieval capability. The data is read and independently verified at the package destination.

Claims

1. A computer implemented method for verifying the integrity of a package at an intermediate test and carrier transfer point on a shipping route comprising:

receiving the package from a first carrier at the intermediate test and carrier transfer point;

obtaining package data from the package using a measurement system operatively connected to the computer at the intermediate test and carrier transfer point on the shipping route;

independently obtaining a package data copy by using the computer to access a data storage system used for storing a plurality of package data records received from a shipper measurement system at a trusted shipping point on the shipping route; and

comparing the package data obtained from the package with the package data copy in order to provide integrity data using the computer, wherein the intermediate test and carrier transfer point is located beyond the trusted shipping point on the shipping route, wherein

the package data comprises an electromagnetic wave response signature associated with a physical change in an electromagnetic wave source signal after it strikes the package; and

releasing the package to a second carrier at the intermediate test and carrier transfer point only if the integrity data is satisfactory.

2. The method of claim 1 wherein:

the package data comprises a digital signature authenticating the shipper; and

the first carrier adds a record to the package data at the intermediate test and carrier transfer point.

3. The method of claim 2 further comprising:

obtaining the package data copy from a trusted third party.

4. The method of claim 2 further comprising:

obtaining the package data from the digital signature having partial message recovery capability.

5. The method of claim 1 wherein:

the package data comprises weight data and secure time data related to the time the package was processed at the intermediate test and carrier transfer point.

6. The method of claim 1 wherein:

the package data comprises size data and density data.

7. The method of claim 1 wherein:

the electromagnetic wave response signature includes a package response to an x-ray source.

8. The method of claim 7 further comprising:

measuring a local package electromagnetic wave response signature to determine the package copy data.

9. The method of claim 8 further comprising:

obtaining source parameter data from the package data; and

measuring the local package electromagnetic wave response signature to determine the package copy data using the source parameter data.

10. The method of claim 9 further comprising:

determining a security parameter based upon the comparison.

11. The method of claim 9 further comprising:

determining a security parameter based upon the comparison and a shipper history parameter, wherein

the shipper history parameter is determined using shipper history incident data relating to trustworthiness.

12. The method of claim 11 wherein:

the security parameter comprises at least three security levels.

13. The method of claim 11 wherein:

the shipper history parameter is obtained from a trusted third party.

14. The method of claim 1, further comprising:

then providing a payment release indication for payment to the first carrier only if the integrity data is satisfactory.
