[Technical Insights] DVR Forensics: Video Retrieval Technology-Research on Target Detection

Editor's Note: In this issue, data experts from SalvationDATA will introduce an essential technique, target detection, used for video retrieval. Among all the techniques used today for target detection, background modeling, featuring less calculation, low storage memory occupation, real-time and high robustness, is the most popular one. Cameras are deployed, nowadays, on almost every street thanks to the Surveillance Web project that requires every corner to be monitored. And the implementation of this project requires massive amounts of video clips to be stored. So how we can extract from it valuable leads that can help investigators crack a case becomes crucial.


[Technical Insights] DVR Forensics: Video Retrieval Technology-Research on Video Decoding

Editor's note: Recent years have witnessed tremendous social development, increasing population migration and fast exchanging of information, all of which entails the constant transformation of the ways police department used to conduct forensics in order to meet ever-changing forms of crime. To meet this challenge, more and more hi-tech devices have been equipped, in recent years, for the police department to combat crimes. And DVR forensics, as one of the key branches of forensics, plays a crucial part in facilitating the transformation. To get a better understanding of DVR forensics, forensic experts from SalvationDATA will explain, starting from this issue, their research on DVR forensics.

[Technical Article] Recover Data from Encrypted External Hard Drive (USB Port)

This issue covers the forth technique application case study conducted by SalvationDATA technicians — data recovery through the opening of a WD 1TB external hard drive. The hard drive involved in this case study was badly scratched and double-secured (hard drive firmware encryption + USB firmware encryption), which makes this case study a typical one. Recovering data from this hard drive is quite different and much more difficult, because normal hard drives can generate image file and access data after changing the magnetic head, but this one cannot. To recover data from the double-secured hard drive with USB port, we needed to have its circuit board changed twice and obtain the key for decrypting the hard drive through initiating WDunlocker by simulating data needed for decryption. No data can be recovered from the image file of said hard drive unless the hard drive is decrypted.
