Method and system for matching unknown software component to known software component
First Claim
1. A computer system that identifies components, comprising:
- a component fingerprint storage configured to memorize known fingerprints of known components, wherein a component is a specific version of pre-existing executable code or a reusable pre-existing self-contained code building block which is not a complete alone finished product ready for use and which is binary or source code; and
a processor cooperatively operable with the component fingerprint storage, and configured to facilitate, based on an unknown component;
determining internal components included within the unknown component;
generating fingerprints for the unknown component and finger prints for all the internal components determined to be included in the unknown component;
determining whether any of the fingerprints generated for the unknown component and for the components included in the unknown component match any of the known fingerprints of known components; and
determining whether the unknown component matches any of the known components based on matching of the known fingerprints of the components included in the unknown component.

Abstract
A computer system or method identifies components. A component fingerprint storage is configured to memorize known fingerprints of known components. The term “component” used herein is defined to be a specific version of pre-existing executable software, or a reusable pre-existing self-contained software code building block which is not a complete stand-alone finished product ready for use and which is binary or source code. A fingerprint is generated for a normalized unknown component and fingerprints are generated for all normalized components included in the unknown component. It is determined whether any of the fingerprints generated for the normalized unknown component and for the normalized components included in the unknown component match any of the known fingerprints of known components.

7. A computer-implemented method for identifying a component, comprising:
-
memorizing, in a component fingerprint storage, known fingerprints of known components, wherein a component is a specific version of pre-existing executable code or a reusable pre-existing self-contained code building block which is not a complete alone finished product ready for use and which is binary or source code; and based on an unknown component; determining, in a processor, internal components included within the unknown component; generating, in the processor, fingerprints for the unknown component and fingerprints for all the internal components determined to be included in the unknown component; determining, in the processor, whether any of the fingerprints generated for the unknown component and for the components included in the unknown component match any of the known fingerprints of known components of the component fingerprint storage; and determining, in the processor, whether the unknown component matches any of the known components based on matching of the known fingerprints of the components included in the unknown component. - View Dependent Claims (8, 9, 10, 11, 12)

13. A non-transitory computer-readable storage medium comprising instructions for execution by a computer, the instructions including a computer-implemented method for identifying a component, the instructions for implementing:
-
memorizing, in a component fingerprint storage, known fingerprints of known components, wherein a component is a specific version of pre-excitable code, or a reusable pre-existing self-contained code building block which is not a complete stand-alone finished product ready for use and which is binary or source code; based on an unknown component; determining, in a processor, internal, components included within the unknown component; generating, in the processor, fingerprints for the unknown component and fingerprints for all the internal components determined to be included in the unknown component; determining, in the processor, whether any of the fingerprints generated for the components included in the unknown component match any of the known fingerprints of known components or the component fingerprint storage; and determining, in the processor, whether the unknown component matches any of the known components based on matching of the known fingerprints of the components included in the unknown component. - View Dependent Claims (14, 15, 16, 17, 18)

19. A computer-implemented method for generating a universal fingerprint for a Java component, comprising, in this order:
-
responsive to an unknown component which is a Java component, for the Java component, in a processor, normalizing the Java component according to a Java normalization process to provide a normalized Java component; and generating, in the processor, the fingerprint for the normalized Java component, as a universal fingerprint, wherein the fingerprint is a hash value, and the Java normalization process performs the following on the Java component; setting class version to 0, resetting synthetic class access flags, setting outer class name to null, setting constant pool and inner class list in alphabetical order, resetting final access flag of Java enumerations #values method, removing all synthetic member fields and Java methods, and removing all package names.
