US 2010/0169654 A1 · METHOD FOR AUTHOR VERIFICATION AND SOFTWARE AUTHORIZATION

Abstract

Embodiments of the present invention are directed to a computer-implemented method for author verification and authorization of object code. In one embodiment, program object code is linked with a plurality of data blocks to create linked object code and a MAP file. Thereafter, author verification is performed by executing a plurality of comparisons between the linked object code and the MAP file. In another embodiment, a digital signing procedure is performed on linked object code by creating a signature data block. The signature data block is then encrypted and written to the linked object code to create digitally-signed object code. In another embodiment, an application program embodied in linked object code generates a data packet. The data packet is then compared to a previously-generated signature data packet from the linked object code to determine if the linked object code is authorized.

Dependent claims

A computer-implemented method of verifying object code, said method comprising:

linking program object code with a plurality of data blocks, wherein said linking creates linked object code and an associated map file;
and
executing an authorization of said linked object code upon execution of said linked object code, wherein said authorization comprises performing a plurality of comparisons of said linked object code with said associated map file.

A computer-readable medium having computer-readable program code embodied therein for causing a computer system to perform a method of authorizing object code, said method comprising:

linking program object code with a plurality of function object codes, wherein said linking produces linked object code;
performing a digital signing procedure of said linked object code comprising:
creating a first signature data block comprising information about said linked object code and a computer-system identifier of a computer system authorized to operate said linked object code;
encrypting said first signature data block;
and
writing said first encrypted signature data block to said linked object code to create a digitally-signed object code.
