This article reports on a study conducted to determine whether a submitted recording was consistent with having been produced on a provided Samsung camcorder.
Abstract
The presence and statistical consistency of the eccentricity in the test recording supported the claim that the submitted recording was consistent with having been produced on the Samsung camcorder submitted for analysis; however, because the degree to which the eccentricity in the date/time information was unique to the submitted camcorder was not tested by the authors, an explicit determination that the submitted recorder produced the submitted recording, to the exclusion of all other Phase-Alternation Line (PAL) MiniDigital Video (MiniDV) camcorders, could not be made solely on the basis of the date/time metadata analysis. The detailed analysis of the recording date/time information provided valuable information on the submitted recording which, when combined with the results of the visual/aural analyses, aided in forming conclusions about the authenticity of the submitted MiniDV tape. Through the analysis of the actual digital data stream, the nonstandard pattern of the date/time information was confirmed and determined to be consistent with the test recording produced on the Samsung camcorder. These findings led to the decision by an official disciplinary committee to accept the submitted recording as evidence. This report recommends further research that can assist in identifying whether a recording was made on a particular camcorder. Details are presented regarding the investigative techniques that established the distinctive characteristics of the video recording that linked it to the particular camcorder. 10 tables, 1 figure, and 9 references
