Determining The Source Of The Creation Of Digital Content Is Considered One Of The Most Popular Open Questions In The Multimedia Forensics Community. So Far, Light Response Non-Uniform Noise Extraction (PRNU) Has Been Proposed As A Means Of Identifying Sensor Fingerprints. It Can Be Judged By Multiple Images Taken By The Same Camera Using The Noise Removal Filtering Process. A Noise Model Based On Signal Correlation Is Proposed And Compared With Other Commonly Used Models For This Purpose. The Technical Basis And Experimental Results Are Introduced And Discussed.
