I. Data Acquisition Sequence Method – Disk Image Recovery

Step 1 Recovery Method Selection

You can select the recovery target among three options, Storage, Image and Damaged file. We will select ‘Image’ option to recover video data from acquired disk image. GMDSOFT

 
Step 2 Importing Image file

You’ll get to the Directory exploring screen. If you click ‘Open’ button, the target image file will be shown based on the extension type such as mdf, bin and E01.

Once the image file is selected, a name, size and file system for the image file will be identified in the attribute tab.

 

 

Step 3 Recovery Option Selection

MD-VIDEO will show you the file signature and codec which are identified from the filesystem. If the file or codec is not recognized, it’ll be labelled as ‘Unknown’.  On this sequence we will select ‘Skip Recovery’ option.

 

 

Step 4 Filesystem / Media Exploring

 

You can access the directory of disk images through ‘Filesystem’ and check the file status via ‘File viewer’.

The Audio and Video speed can be controlled and Viewer size can be adjusted.

In ‘Analysis Results’ section, you can see recognized video files by format. You can select all of the sorted video files or individually.

Also, in the media viewer section, there is several tabs that helps user to recognize file specifications such as “Attribute”, “Data”, “Leave Comments” and “Custom”. On the “Attribute”, there is file information and file hex value appears on the “Data” tab. Also, user can easily leave comment to log description for the file. On top of that, custom codec can be imported on the “Custom” tab.

 

 
Step 5  Export File and Report

Also, there are ‘Export function.’ With this function, there are 2 ways to exporting. One is ‘Export File’ to export the file from the filesystem to the location set by user. It will also provide converting function as you can see in the figure. The other one is ‘Export Report’ to make report as PDF or XLSX format for guaranteeing integrity as evidence. Also, you can decide how to design the report. We choose the default way to export report.

The result is shown in figure. Firstly, MD-VIDEO will make cover page of report. Secondly, there will be the table of contents of report. As last, it will show about the video which we analyze in MD-VIDEO. Each video have the hash values to guarantee these video have integrity

 

 

2 . Data Acquisition Sequence Method – Damaged Video File

Step 1 Recovery Method Selection

To recover video data from damaged file, you can select third option ‘Damaged File’.

 

 
Step 2   Importing damaged file

With those buttons, you can put files or folders to recover the video from. We put a damaged file named ‘2017_09_04_07h_27m_42s_F_event_Broken.avi.’

 

 
Step 3  Recovery Option Selection

Once you put a file, MD-VIDEO will automatically scan the file and show these results, file signature and codec in the file. Due to the file is damaged, there was no file signature and codec identified from this file. To see ‘frame recovery function,’ we will skip recovery in this process.

 

 

 
Step 4  Recovery with frames

So, the damaged video will be recovered by MD-VIDEO’s frame recovery function. To recover with frame, select the files which need recovery and have to click “Recovery” button on the left side. After option screen pops up, you can select ‘Frame Recovery’ menu. Also, to get precise recovery result, you have to know specific codec of video file. In this case, the codec was identified as ‘H.264’ based on other active video files’ codec.

After select codec, MD-VIDEO starts the frame recovery process

 

 

Step 5  Recovered Frames

After ‘frame recovery’, list of recovered frames will appear as ‘Analysis Results. Based on the extracted frames appeared above, MD-VIDEO can recrate video.

 

 

Step 6  Export File and Report

MD-NEXT has export function for both source-result files and report. With export function, you can convert recovered frames to video formats. Also, you can still export each of recovered frames to photo file, even for sound formats.

In case of report generation, the generated reports contain about the case and evidence information. For strong integrity, MD-NEXT calculates each of hash value for the extracted frames and the hash value data is also contained into the report.

 

Interview of GMDSOFT : Kim Hyun-soo(CEO)

1. Tell us a bit about your role: what does a day in your life look like?

I am Kim Hyun-soo, a founder of GMDSOFT.

Over the years, my daily routine is very focused on the sole purpose, making a perfect solution to empower digital investigations and how we can add more value to the mobile forensic market.

I start my day jumping right to my phone and check to see how things are going with the business. It’s always exciting to wake up and check on the progress of evidence commissioned by clients from overseas.

From the moment I get into the office, I spend a majority of time traveling for meetings with clients and chief executive officers in a HANCOM group, attend conferences, and other business-related gatherings each year.

HANCOM group is formed of fourteen companies, so if we have an active project going on, my schedule gets busier than it would normally.

Like many other CEOs, I wake up to emails and go bed to emails and being at home never means that I am off. It has never been easy to lead a company, but I love to take these responsibilities to grow a company and help society with empowering many investigators.

2. Tell us a little more about GMDSOFT, how your company was founded, and your mission/vision/values for your customers and the tools you’re building for them?

It was at a time when the mobile era was beginning to set in motion when I jumped into the mobile forensic market. I was a former computer technology developer specialized in programming and had a desire to run a company that can create added value with software technology.

We know there’s a variety of software applications and I think the value of software depends on where it’s applied. I’ve been looking for a new field where I can be more creative and create added value.

Since mobile was a hot topic at the moment, I took a turn toward mobile forensic technology research and development.

At that time, scientific research and technology development in mobile forensics were barely done in South Korea.

Thus, I visited the National Police, National Intelligence Service, and all the law enforcement agencies in person and explained the platform I am planning and conduct a demand survey. Confident of its potential as the positive response returned, I saw it as an excellent opportunity, and GMDSOFT, the mobile forensic research and development company was established in 1997. After joining with a HANCOM Group, we have a better solution for stable business management and synergy to expand fast in the global market.

I’m proud that GMDSOFT is the only mobile forensic company listed on KOSDAQ which opened a new market for mobile forensics in South Korea. As a result of the business with the national investigative agency from the beginning, the state agency now controls more than 80% of its major sales outlets.

We are confronting increasing intelligently evolving security threats, and many more challenges, GMDSOFT as a leading mobile forensic research group provides the solution when the national issue arises.

We also take part in a digital forensic investigation for audits and law firms. As such, the number of areas where the mobile forensic solution is applied is increasing in South Korea.

Also, for some rare occasions, we are asked to investigate smartphones from individuals to find digital evidence for their family or friends who already got in an accident, suicide, or other unjust cases. By discovering meaningful digital evidence for them, we realize once again that GMDSOFT is doing something beneficial and valuable job for our society.

GMDSOFT has a sole mission, which is ‘We provide the best solution to empower investigation.”

Hence, our teams comply with below two principles.

First, we take full responsibility for developing ‘creative technology.’

Our research team comes up with many creative and innovative ideas to provide a solution for our clients. Since the digital landscape is evolving rapidly and so too is digital forensics, our research teams are encouraged to apply new technologies and research on the latest digital forensic technology to empower investigation.

Second, all of our products and services are ‘customer oriented.’

GMDSOFT should satisfy customers’ demands and expectations. Our sales and technical support team regularly visit clients and receive their feedback and inquiry.

I think keeping good relationships and communication with customers and prompt response to their needs are the key elements to improve GMDSOFT.

3. Your company announced last month that it had been awarded the Outstanding International Collaboration in a Complex Digital Investigation. Congratulations!

Can you tell us a little about the award and your role in the case that caught the award committee’s attention?

The award is a special award for successfully solving a mobile forensic case commissioned by British police. It was a case where we had to get the evidence data from the suspect’s smartphone.

It was the latest smartphone model with secure boot setup, and the suspect was insisting that it was his child who set up the password while using it. Our research team was able to unlock secure boot successfully and helped to find evidence of its’ case with our tool MD-NEXT and MD-RED.

Your press release noted that this was the first time a Korean firm has been recognized at these awards. What does this recognition mean to you?

This event has an extraordinary meaning that our technology is highly recognized in the UK, a place of digital forensics. Moreover, it was only GMDSOFT who successfully provided a solution to this case within a week, while none of the mobile forensic companies were able to provide a solution for over months.

Moreover, GMDSOFT was the first Asian company to be awarded in ICDDF for successful cooperation with law enforcement in Europe, and it’s a massive help for us to carry out our business in a global market.

How did working with your customer on this case help you to improve your product(s)?

I think the conductivity level in digital forensic technology in the UK is one of the best in the world. It was also the UK where we, founders of CTO and I, had the first experience in mobile forensics.

By working closely with customers in the UK and receiving many inquiries and feedbacks from the frontline investigators, we believe our product MD-Series can be improved thoroughly and satisfy many investigators around the world.

Also, furthermore, we are applying new features and solutions rapidly to our product as we receive various inquiries from the UK with the issues on the latest technology such as drone, self-driving cars, smart TV and many more.

You’ve also secured contracts with the West Midlands Counter Terrorism Unit and Leicestershire Police for your MD-NEXT and MD-RED products.

How do you anticipate your experience, in this case, will help you partner with other customer agencies?

The success story of UK police was made after our product got through their product qualification process, which took about six months comparing data analysis from a few other mobile forensic tools on the real evidence phones. Especially, our products have shown the superior result in Asian smartphone extraction and diverse apps analysis to other competitors. This means our product can do an essential role as a complementary tool to verify the results from existing mobile forensic tools. This success story is spread by word of mouth, and we are having product demonstration inquiries from the other UK policies since then, now we are expecting to have more achievement in the UK and other European countries as well.

Can you give us any hints as to what else we might expect to see from HancomGMD this year?

This year we are highly focused on the mobile forensic market in the European region, including the UK and India. We have more business opportunities in these two regions.

We will support clients from these regions and develop our products, furthermore, we are looking forward to presenting our new product lines, which performs data acquisition and analysis on cloud services, data recovery tool for universal CCTV/DVR/Vehicle media and video analytics tool based on AI technology.

When you’re not working, what do you enjoy doing in your spare time?

I think staying highly innovative and focused on the market is essential.

Even though I no more work as a software developer, I am still fascinated with learning and developing skills that are related to new technology.

Whenever I am outside of work, I love browsing tech savvy’s blog, journal, and subscribe to the YouTube channel. It’s a highly recommended way to learn new things for those with minimal time.

In recent years, I have been spending most of my spare time thinking of a strategy to grow our new business in VR, drone, IoT, and AI technology. It’s a big challenge and fresh experience to put myself in a new field.

Lastly, our global business team and I spend much time and put effort to find cooperative partners or visionary investors overseas. We are kicking off 2019 with intensive global business strategies.

We are always welcoming anybody who would like to work with and to lead this mobile forensic market; Somebody like you who dream high and have a strong passion!
