KUALA LUMPUR, Jan 15 (Bernama) -- A digital forensic expert told the Royal Commission of Inquiry today that the "Lingam" video clip was authentic and that it had not been edited.

Cyber Security Malaysia senior analyst Mohd Zabri Adil Talib said the analysis based on three CD samples and one DVD sample were handed over to the Anti-Corruption Agency (ACA) to verify their authenticity.

"An analysis report was also given to the commission's investigation officer (Chuah Lay Choo) on Jan 14 (yesterday).

"The analysis found that the object's movements recorded were consistent. This proves that the recording was authentic and had not been edited," he told coordinating officer Datuk Azmi Ariffin.

Mohd Zabri, 28, a Computer Science graduate from Universiti Teknologi Malaysia (UTM) was the fifth witness called to testify on the second day of the inquiry into the video recording purportedly showing a senior lawyer on the phone with a senior judge discussing judicial appointments.

He said the analysis on a CD containing an eight-minute video clip was received on Oct 11, a 14-minute CD on Dec 26, and a DVD containing audio sample on Jan 8.

Mohd Zabri said the analysis focused on the video frames to trace signs of tampering and also studied the consistency of the frames.

It was trained on the object's movement recorded in the video file to verify its authenticity or that had been edited from the first to the final files.

The analysis also focused on spectrograph to check the surrounding sound and found there was no drastic difference and that the audio sound was also consistent to the end.

Mohd Zabri who have been with the firm since January 2007 concluded that the audio file extracted from the video recording was consistent and that there was no editing and dubbing involved.

Commissioned by the Global International Assurance Certification as a certified forensic analyst, he conducted the analysis at the Agnitio S.L biometric laboratory in Madrid, Spain.

Mohd Zabri said he went to Madrid accompanied by ACA officer Azam Baki, Putrajaya ACA Supt Wan Zulkifli Wan Jusoh and Cyber Security officer Asmawi Fadilah Mohd Arifin.

The analysis also found that the voice on two samples were that of Lingam.

Earlier, Wan Zulkifli from the ACA forensic division said he downloaded the 14-minute video clip to his computer before transferring it to a CD on Dec 8.

He said he handed the CD to investigating officer Senior ACA Supt Chuah before asking him to send it to Cyber Security on Dec 26. This was in addition to the eight-minute clip sent on Oct 11, he said when replying to coordinating officer Datuk Nordin Hassan.

He said a DVD sample of the voices of 22 Malaysians and a CD with the voice of Datuk V.K. Lingam received by ACA Supt Moses Lawrence were also sent to Cyber Security.

Wan Zulkifli said the three CDs and one DVD were handed over to Mohd Zabri.

He also told Lingam's lawyer R. Thayalan that the video clip recording downloaded from Anwaribrahimblog.com was not the original copy and that nothing was done to improve the sound quality or the copy quality.
