Abstract

The disclosure includes a system and method for extracting, using one or more processors, metadata from a first media file, wherein the metadata is distinct from media content; encoding, using the one or more processors, a first portion of the metadata extracted from the first media file into a first metadata-encoded media signature; and determining, using the one or more processors, whether the first metadata-encoded media signature is indicative a defect.

First claim

What is claimed is:

1 . A method comprising:
extracting, using one or more processors, metadata from a first media file, wherein the metadata is distinct from media content; encoding, using the one or more processors, a first portion of the metadata extracted from the first media file into a first metadata-encoded media signature; and determining, using the one or more processors, whether the first metadata-encoded media signature is indicative of a defect including one or more of:
an intra-transaction analysis determining whether the first metadata-encoded media signature is consistent with a second metadata-encoded media signature associated with a second media file, wherein the first media file and second media file are associated with a common transaction; and
an inter-transaction analysis determining whether the first metadata-encoded media signature is consistent with a third metadata-encoded media signature associated with a third media file, wherein the third media file is associate with a prior transaction.

2 . The method of claim 1 , wherein determining whether the first metadata-encoded media signature is indicative of the defect comprises an intra-media analysis including one or more of:
determining whether the first metadata-encoded media signature indicates an inconsistency between two or more metadata values, wherein each of the two or more metadata values are associated with a different set of metadata associated with the first media file but include an informational overlap; and determining whether the first metadata-encoded media signature indicates an absence of expected metadata.

3 . The method of claim 2 , wherein the different metadata sets include at least one from a group of: exchangeable image file format (EXIF) metadata, extensible metadata platform (XMP) metadata, International Press Telecommunications Council (IPTC) metadata, International Color Consortium (ICC) Profile metadata, comment metadata, and thumbnail metadata.

4 . The method of claim 1 , the method further comprising:
obtaining one or more of the second metadata-encoded media signature associated with the second media file and the third metadata-encoded media signature associated with the third media file.

5 . The method of claim 1 , wherein determining whether the first metadata-encoded media signature is indicative of the defect includes one or more of:
cross-referencing the first metadata-encoded media signature to determine whether the first metadata-encoded media signature is consistent with a representative signature generated via aggregation; cross-referencing the first metadata-encoded media signature against one or more values within, or derived from, the media content; and cross-referencing the first metadata-encoded media signature against source information.

6 . The method of claim 1 , wherein the first metadata-encoded media signature includes a vector representation, the first metadata-encoded media signature encoding one or more metadata fields that are present or absent from the metadata.

7 . The method of claim 1 , wherein the first metadata-encoded media signature includes encoded values associated with present metadata field.

8 . The method of claim 1 , wherein the encoding includes one or more of a weighted and proximity encoding.

9 . The method of claim 1 , wherein the media content is image-based and includes pixel data associated with one of at least one video frame and a still image.

10 . The method of claim 1 , wherein the first metadata-encoded media signature includes a graphical representation, the first metadata-encoded media signature encoding one or more metadata fields that are present or absent from the metadata.

11 . A system comprising:
a processor; and a memory, the memory storing instructions that, when executed by the processor, cause the system to:
extract metadata from a first media file, wherein the metadata is distinct from media content;
encode a first portion of the metadata extracted from the first media file into a first metadata-encoded media signature; and
determine whether the first metadata-encoded media signature is indicative of a defect including one or more of:
an intra-transaction analysis determining whether the first metadata-encoded media signature is consistent with a second metadata-encoded media signature associated with a second media file, wherein the first media file and second media file are associated with a common transaction; and
an inter-transaction analysis determining whether the first metadata-encoded media signature is consistent with a third metadata-encoded media signature associated with a third media file, wherein the third media file is associate with a prior transaction.

12 . The system of claim 11 , wherein determining whether the first metadata-encoded media signature is indicative of the defect comprises an intra-media analysis including one or more of:
determining whether the first metadata-encoded media signature indicates an inconsistency between two or more metadata values, wherein each of the two or more metadata values are associated with a different set of metadata associated with the first media file but include an informational overlap; and determining whether the first metadata-encoded media signature indicates an absence of expected metadata.

13 . The system of claim 12 , wherein the different metadata sets include at least one from a group of: exchangeable image file format (EXIF) metadata, extensible metadata platform (XMP) metadata, International Press Telecommunications Council (IPTC) metadata, International Color Consortium (ICC) Profile metadata, comment metadata, and thumbnail metadata.

14 . The system of claim 11 , wherein the instruction, when executed, further cause the system to:
obtain one or more of the second metadata-encoded media signature associated with the second media file and the third metadata-encoded media signature associated with the third media file.

15 . The system of claim 11 , wherein determining whether the first metadata-encoded media signature is indicative of the defect includes one or more of:
cross-referencing the first metadata-encoded media signature to determine whether the first metadata-encoded media signature is consistent with a representative signature generated via aggregation; cross-referencing the first metadata-encoded media signature against one or more values within, or derived from, the media content; and cross-referencing the first metadata-encoded media signature against source information.

16 . The system of claim 11 , wherein the first metadata-encoded media signature includes a vector representation, the first metadata-encoded media signature encoding one or more metadata fields that are present or absent from the metadata.

17 . The system of claim 11 , wherein the first metadata-encoded media signature includes encoded values associated with present metadata field.

18 . The system of claim 11 , wherein the encoding includes one or more of a weighted and proximity encoding.

19 . The system of claim 11 , wherein the media content is image-based and includes pixel data associated with one of at least one video frame and a still image.

20 . The system of claim 11 , wherein the first metadata-encoded media signature includes a graphical representation, the first metadata-encoded media signature encoding one or more metadata fields that are present or absent from the metadata.
