Abstract
Abstract A system and method for verifying and authenticating multimedia objects. Provided is a system for splitting a watermark into at least a first and second part, inserting the first part of the watermark into a first component of the multimedia object, and inserting the second part into a second component of the multimedia object, and outputting a watermarked multimedia object. The watermark may be provided by obtaining a signature of the original multimedia object. Also included are systems and methods for checking the validity and authenticity of a received watermarked multimedia object, wherein the multimedia object includes individual watermarked media components.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
65 words
A method of protecting a multimedia object having a first media component and a second media component, comprising the steps of: providing a watermark; splitting the watermark into a first part and a second part; inserting the first part of the watermark into the first media component; inserting the second part of the watermark into the second media component; and outputting a watermarked multimedia object.
Claim 2
Independent Claim
65 words
A method of protecting a multimedia object having a first media component and a second media component, comprising the steps of: providing a watermark; splitting the watermark into a first part and a second part; inserting the first part of the watermark into the first media component; inserting the second part of the watermark into the second media component; and outputting a watermarked multimedia object.
Claim 3
Dependent Claim
78 words
The method of claim 1 , comprising the further steps of: receiving the watermarked multimedia object; extracting from the first media component of the watermarked multimedia object a first extracted watermark part; extracting from the second media component of the watermarked multimedia object a second extracted watermark part; combining the first extracted watermark part with the second extracted watermark part; and comparing the combined first and second extracted watermark parts with the provided watermark to verify an ownership.
Claim 4
Dependent Claim
35 words
The method of claim 1 , wherein the watermark is a signature watermark and is provided by: obtaining a signature of the multimedia object; and generating the signature watermark as a function of the signature.
Claim 5
Dependent Claim
96 words
The method of claim 3 , comprising the further steps of: receiving the watermarked multimedia object; extracting from the first media component of the watermarked multimedia object a first extracted watermark part; extracting from the second media component of the watermarked multimedia object a second extracted watermark part; generating a combination watermark by combining the first extracted watermark part with the second extracted watermark part; generating a signature watermark that is a function of a signature extracted from the watermarked multimedia object; and comparing the combination watermark with the signature watermark to authenticate the multimedia object.
Claim 6
Dependent Claim
65 words
A computer program product for protecting a multimedia object having a first media component and a second media component, said product including instructions, within a computer-readable medium, executable by a processor to carry out acts comprising: splitting a watermark into a first and a second part; inserting the first part into the first media components, and inserting the second part into the second media component.
Claim 7
Dependent Claim

Claim 11
Dependent Claim
75 words
The product of claim 6 , further comprising instructions executable by said processor to carry out acts comprising: extracting a first extracted watermark part from the first media component in the watermarked multimedia object; extracting a second extracted watermark part from the second media component in the watermarked multimedia object; combining the first extracted watermark part with the second extracted watermark part; and comparing the combined first and second extracted watermark parts with the watermark.
Claim 12
Dependent Claim
92 words
The product of claim 8 , further comprising instructions executable by said processor to carry out acts comprising: extracting a first extracted watermark part from the first media component in the watermarked multimedia object; extracting a second extracted watermark part from the second media component in the watermarked multimedia object; generating an extracted watermark by combining the first extracted watermark part with the second extracted watermark part; generating a signature watermark that is a function of a signature of the watermarked multimedia object; and comparing the extracted watermark with the signature watermark.
