Alix Melchy - Web page: https://patentgrep.com/patent/US12596702B1 ## CPC - G06F 16/2365: {Ensuring data consistency and integrity} - G06F 16/583: using metadata automatically derived from the content - G06F: ELECTRIC DIGITAL DATA PROCESSING (computer systems based on specific computational models G06N) ## 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. ## Claims ### Claim 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. ### Claim 2 (depends on 1) 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. ### Claim 3 (depends on 2) 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. ### Claim 4 (depends on 1) 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. ### Claim 5 (depends on 1) 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. ### Claim 6 (depends on 1) 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. ### Claim 7 (depends on 1) The method of claim 1, wherein the first metadata-encoded media signature includes encoded values associated with present metadata field. ### Claim 8 (depends on 1) The method of claim 1, wherein the encoding includes one or more of a weighted and proximity encoding. ### Claim 9 (depends on 1) 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. ### Claim 10 (depends on 1) 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. ### Claim 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. ### Claim 12 (depends on 11) 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. ### Claim 13 (depends on 12) 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. ### Claim 14 (depends on 11) 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. ### Claim 15 (depends on 11) 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. ### Claim 16 (depends on 11) 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. ### Claim 17 (depends on 11) The system of claim 11, wherein the first metadata-encoded media signature includes encoded values associated with present metadata field. ### Claim 18 (depends on 11) The system of claim 11, wherein the encoding includes one or more of a weighted and proximity encoding. ### Claim 19 (depends on 11) 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. ### Claim 20 (depends on 11) 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.
