There is more Digital & Multimedia Evidence (DME) than any other type of evidence today.
Working together we've expedited tens of thousands of criminal investigations. Learn more

As each day passes law enforcement and government agencies struggle with managing more sources of digital evidence and multimedia, like body worn cameras. The massive amounts of data storage required have led many to finally consider secure cloud-based storage solutions, but as some have found out, despite the minimal capital investment cloud storage costs can quickly exceed the LE & IT budgets of even the largest agencies. Let's break this down and talk specifically about digital evidence and archiving.

How are you archiving all of your digital evidence today? A tiered storage solution? Hybrid cloud solution? LTO tape? Hard drives? Optical discs (i.e. CD-R, DVD+/-R, BD-R)? Lots of questions and options, so lets talk specifically to the last group; those using optical discs.

Pre-order This Is For Everyone by Sir Tim Berners-Lee

One of our members brought to my attention that the blog post form wouldn't allow you to save and publish your post.  Eventually, I found the reason and resolved it this morning.

You may have seen in a recent newsletter that we're cleaning up our database over the next few weeks.  If you missed that notice here's the skinny - we will be deleting all user accounts that have been inactive for more than 6 months.  If you have logged in within the last 6 months you're good to go; if not, you'll probably be deleted.  Any questions or concerns, as always, feel free to contact me.  Thanks for participating and have a great holiday weekend!

 

I distinctly remember about ten years ago when a local police chief told us that there was no computer crime in his village. I also remember literally laughing out loud when I heard that.(Seriously, I was bent over from laughing so hard.) Digital evidence is being collected at an unprecedented rate each and every single day, and you’d probably be hard pressed to find anyone more intimately familiar with that then your local multimedia, computer, or mobile device analyst.

I’m excited to announce that I’ll be attending this year’s 100th IAI Educational Conference in Sacramento, CA. This year’s conference is anticipated to be one of the largest, as it’s the IAI’s Centennial event. I will be there representing my employer, Ocean Systems, and we will be showcasing our latest Digital & Multimedia Evidence (DME) solutions in the event's Exhibit Hall.

For more information about the event visit the IAI 100th International Educational Conference web site. Hope to see you there!

Understanding video standards is fundamental to aspect ratio correction. Back in the predominantly analog days we had three main standards referenced or used for most video recordings; NTSC, PAL, and SECAM. Then in the early ‘90’s came the first digital multimedia frameworks to reach the average consumer; QuickTime and, shortly thereafter, Video for Windows (VfW).

Today we have dozens of multimedia frameworks, digital video and digital display standards, all of which lead to a great deal of confusion regarding the plethora of acronyms and what they truly mean. AVC or H.264? HEVC or H.265? CIF or SIF? Don’t even get me started on the profiles and parameters available for each standard, as the combinations are truly mindboggling. When it comes to proper Display Aspect Ratio (DAR) though, it really boils down to “Are the originally recorded pixels square or non-square?”

The Scientific Working Group on Digital Evidence (SWGDE)has released a DRAFT of version 3.0 of their "Best Practices for Computer Forensics" for public comment. As stated on their Web site, "The purpose of this document is to describe the best practices for collecting, acquiring, analyzing and documenting the data found in computer forensic examinations."

Well, maybe you are, but not if you're basing it on not being able to enter the proper Captcha code on our forms.  I was notified of an issue with our Google ReCAPTCHA yesterday and am working to resolve it.  I hope to have the issue resolved this weekend and will update once I do.  Thanks for your patience and understanding. ;)
