2 Description

Puma is a rugged and evidentially secure system for archiving Flash card data to

CDROM/DVD media. Its automated backup procedure make it simple to use. It is aimed primarily at backing up digital cameras and Flash based audio and video recorders and includes a RAW to JPEG image converter. Puma will back up any type of file data and can be used to archive USB pen drives and other USB disk drives. The main features are as follows:

• Simple operation. Single, dedicated “Transfer” button initiates entire archive sequence. This eliminates the chance of the operator omitting part of the procedure.

• Any size of card can be archived up using multiple DVDs or CDs (new in V2.1).

• Rugged construction and no hard drive increases reliability and evidential security.

• Unique bit for bit copy of Flash card provides ultimate evidential audit trail and reduces possibility of legal challenges.

• Three automated steps in transfer procedure: Transfer, data verify, and Flash media overwrite/erase/format.

• Flash card, forensic wipe process ensures that deleted data cannot be recovered and removes any viruses.

• Fast transfer rates reduces back-up time. Up to four times faster than laptop for transferring files. 20Mbyte /sec transfer rate.

• Self contained unit with premium quality, full height DVD/CDROM R/W drive.

• Re-mounts and verifies disk after writing to ensure maximum reliability of backup.

• Supports wide range of DVD +/- R, +R/W, +R DL and CD -R media.

• Will back up USB Flash sticks.

• Proprietary software tailored precisely to the needs of law enforcement and evidence gathering. Closed nature of operating system increases evidential security

• Produces two media outputs: a Master Copy which is a bit-for-bit copy of the entire Flash memory card and a Working Copy which contains only the files from the Flash card. Where these are image files in RAW format, the system will generate JPEG versions of these files which will also be stored on the Working

Copy. A list of supported RAW camera formats is given in APPENDIX 1

• Can be powered from mains, vehicle power or external batteries.

• Supports all common Flash media (see Specification).

2. Remove any Flash card.

3. Switch on the Power Switch on the rear panel (switch up). The display panel will light up and show “Press I/O”. The green front panel LED will flash.

4. Press the I/O (On/Off) switch below the green Flashing LED. “On..” will be displayed and the green LED will be on constantly.

5. After a few seconds, a growing line of dots will appear on the display and the system will be ready for use after about 20 seconds.

3.2 Transferring Flash Card Data

1. Check that the displayed time and date are correct.

2. Insert the Flash card into the appropriate front panel slot. The display will show the card’s size and number of files. A USB stick may be plugged into the rear panel.

3. Press the Disk button to open the DVD/CD draw. Place a DVD/CD in the tray and press the Disk button once more to close the tray.

4. Press the TRANSFER button to start the transfer.

a) A Master copy is produced first. This consists of the transfer of the data from the card to the disk and a verification read of the disk image file and the card. On successful completion the Master disk will be ejected and the checksum of the Flash card will be shown. This can be noted down for future reference.

(where multiple disks are produced, there are separate disk checksums also).

b) Remove the Master Copy disk and place a new DVD on the tray. Press the lower soft key Marked “Continue” to proceed. The Working copy is now produced. On successful completion the disk will be automatically ejected.

c) The Flash card may now be wiped and re-formatted. Press “N” when prompted if this is NOT required.

The Transfer is complete.

Note: If further copies are required, do not wipe the card, and use the appropriate functions available in the “Menu”. Press “Menu” soft key and the Up/Down cursor keys.

3.3 Turning Off

Press the I/O button below the green LED to shutdown. When “Switch Off” is displayed, turn off the rear panel Power Switch.

4 Detailed Operation

4.1 Setting up and Powering Puma

1. Connect the supplied 12V 5A power supply (PSU) lead to rear panel power inlet and screw up the connector. Connect the PSU to a mains supply using the supplied cable.

2. Remove any Flash card.

3. Switch on the Power Switch on the rear panel (switch up). The display panel will light up and show “Press I/O”. The green front panel LED will flash.

4. Press the I/O (On/Off) switch below the green Flashing LED. “On..” will be displayed and the green LED will be on constantly.

5. After a few, a growing line of dots will appear. This line will extend to the full width of the screen and then “Wait” will be displayed. A few seconds after that “Ready” will be displayed and the system is ready for use. The whole boot up procedure, from switch on, takes about 20 seconds.

6. When PUMA makes a Working Copy of RAW image files, it creates JPEG versions of these files for ease of viewing across a wide range of platforms. Where this feature is required, it must be enabled from the menu. This is done by selecting the

“Enable JPEGs” function in the Menu (Section 4.13 ).

7. Check that the displayed time and date are correct. If not, use the “Adjust Time” menu function to adjust the time and date (Section 4.15).

4.2 Turning Off (Display Software Revision and Serial Number)

Press the I/O button below the green LED to shutdown. Press {Y} to confirm. When

“Switch Off” is displayed, turn off the rear panel Power Switch.

If {N} is pressed the Software Revision and Serial Number (where appropriate) will be displayed and Puma will resume operation.

4.3 Automated Transfer Operation

1. Place the Flash card in appropriate slot. If a USB drive is to be archived, plug this into either of the USB slots in the rear panel. An extension lead may be required for bulky USB flash drives

2. Place a blank CD-R or DVD +/- R in the drive. The Master Copy is generated first.

The size of the Flash card is shown on the display when it is inserted. A CD will hold

730Mbytes and a standard DVD 4,700 Mbytes. Where the flash card is larger than the disk size, multiple disks will be produced. These disks will be automatically numbered as Master Disk #1, Master Disk #2 etc. A Windows utility program is supplied, which combines the multiple disks into one master image file for ease of access. This utility program, called ImageMaker, is copied to the first disk of the set.

Cypher Technology Ltd 2008 7

The Master Copy has the current time and date stamp as displayed on the front of the machine.

3. Press the Transfer button.

(The “Cancel” soft key allows the transfer to be aborted)

Please note: The first time a new disk type is used, there may be a delay before writing occurs as the drive calibrates itself to the disk.

Menu list.

Pressing the {Exit} soft key once more returns to the top level.

4.16 How is the Master Copy used?

4.16.1 Master Copy – The ultimate evidential exhibit

The Master Copy contains a single file called “flash.img” which is a bit for bit copy of the whole of the Flash card. This includes the files, deleted files, the file system, partition information and all historical file data. As such it provides the most secure, evidential backup and allows the most complete evidential audit trail. It contains everything that was on the Flash card and is the same size (in Kbytes) as the Flash card. The flash.img

file has its time created, modified and accessed values set to the time of the start of the transfer. This time is taken from the system time as displayed on the front panel of the machine at start-up.

When the flash card is bigger than the disk size, multiple disks are needed and each disk will contain part of the image. The first disk will contain a file called flash1.img , the second disk, flash2.img etc. These part images may be combined to form a single, complete image file (see Section 4.18 ).

The Master Copy can be used in two ways. On a PC with an Image Viewer program or by restoring the image back to a Flash card or USB disk.

4.17 Accessing the Master Copy with WinImage

Firstly, the flash.img file on the Master Copy disk can be opened with a disk image viewer program. Such a program is WinImage, a trial version of which may be downloaded from: http://www.winimage.com/download.htm

Cypher Technology Ltd 2008 13

Fig 3. Winimage screen display under Windows XP

The viewer programs allow the user to open the flash.img file as if they were opening a disk in Windows explorer. Individual directories can be viewed and opened and their files accessed or copied.

4.18 ImageMaker – Combining Multiple Disk Images

If the Master is split across several disks, the ImageMaker utility, on Master Disk #1 must be run to combine the images on the different Master Disks into one file. To run

ImageMaker, place Master Disk #1 in the PC drive. Double click on the ImageMaker icon and run the program.

Fig 4. ImageMaker screen display under Windows XP

Select the destination folder with the Browse tab and then click {Start} to start conversion. When the first disk is complete, then load disk #2. Follow the on screen instructions until all disks have been transferred. After each disk is completed the

Cypher Technology Ltd 2008 14

following dialogue box is shown. After the last disk, press the {Finish} button to close the image file.

Fig 5. ImageMaker dialogue

The name of the new, combined image file is shown in the message window and is generated from the original image file name and the current date and time.

Fig 6. ImageMaker final screen

The Checksum shown at the end should be the same as the checksum noted down during the making of the Master. Restore the Master Image to a Flash Card

This single .img file can be accessed by WinImage in the normal way.

Restore the Image Back to a Card

Secondly, the disk image can be copied back to a flash card of equal or greater size than the flash.img file (and therefore the original Flash card). This copied flash card will behave as an exact clone of the original allowing, for example, the un-erasing of files and the forensic examination of file allocation addresses and access dates. On Puma this task is performed by the Restore Master function (see Section 4.8).

Cypher Technology Ltd 2008 15

5 Technical Background

5.1 Master Copy (bit for bit copy)

The Master Copy contains a single file called “flash.img” which is a bit for bit copy of the whole of the Flash card. Because the whole of the card is copied, the Master includes hidden files, deleted files, historical file data fragments, original time-accessed and timemodified data, the filing system (FAT), and the boot sector and partition information.

As such it provides the most secure, evidential backup and allows the most complete evidential audit trail. It contains everything that was on the Flash card and is the same size (in Kbytes) as the Flash card.

Simple card copiers only copy the undeleted, non-hidden files. This leaves the exhibit open to legal challenge.

5.1.1 Why archive the file system?

First some technical background on how files (such as pictures in a digital camera) are stored on a Flash card.

A file is a digital container for digital data. As an example, one digital still image is normally stored in one file. The file has a name and this is how it is referenced and accessed (e.g. DSC_0001.JPG).

A filing system on a disk or Flash card is used to show where all data in the files is located on that disk or Flash card.

A filing system (such as the FAT16 or FAT32 system ) consists of two parts: a file allocation table and the file data itself.

5.1.2 Partition Table

Sometimes it is useful to divide one physical disk (e.g. a hard disk) into multiple drives

(c: drive, e: drive etc.). A partition table describes how the drive is divided into different virtual disks. Flash cards and USB pen drives consist normally of one partition, but still normally contain a partition table. Strictly speaking they don’t need a partition table and some flash cards don’t have one. Also, Windows XP will format a wiped, blank flash card with no partition table.

The partition table is not updated after it is created but the way the partition table is written will vary from system to system and thus can give some knowledge of the history of the card.

5.1.3 File Allocation Information

Most Flash media cards use the FAT16 or FAT32 file system. When a file (e.g. a JPEG picture file in a camera) is created, two things happen. Firstly the file data is written to the data area of the card and secondly the file allocation table is updated. The file allocation table contains such information as the file name, the file creation/modification times and dates and of course where the file data lives on the card.

Cypher Technology Ltd 2008 16

5.1.4 File un-deletion

When a file is deleted the actual file data is normally left unchanged on the storage device. The deletion involves marking the file name in the file table to show that the file is no longer required and that the data space that was being used on the card can be used for new files. Because of this, if no further data is written to the card, the original deleted file may be retrieved or “un-deleted”. The Master Copy allows for un-deletion of files where it was possible on the Flash card. (See “How is the Master Copy used?” above). The Working Copy, of course, will not contain deleted files.

5.1.5 Historical file data

When a file is copied from the Flash card to another storage device (as with the

Working Copy) information about its creation may be lost. Most obviously this may include the original modification and creation times from the Flash file table but also more subtle historical information may be lost relating to the media history.

5.1.6 Media History

When a file is created on a blank piece of media, the storage space is generally allocated from the beginning of the data area. Once several files have been created and then a few have been deleted “holes” appear on the file data area where the old file data resided. These holes will eventually be overwritten with new file data as new files are created, but because these new files may be of different sizes to the old files, one new file may have its data spread across the disk at various locations. The more a

Flash card or drive is used, the more fragmented it becomes. This gives valuable information about the use of the media and the time of creation or modification of a file.

The Master Copy preserves all this information as it provides an exact snapshot of the state of the card when the copy is taken and because it leaves all the card data unchanged within the backup. The Master Copy is therefore the most important evidential backup.

5.2 Disk Verify Read

Most backup programs simply copy the data to the backup medium and assume it has been written correctly and can be re-read. With optical disks this is particularly dangerous. PUMA dramatically reduces the chance of producing unreadable disks by performing a verify read of the disk after it has been written. The verify pass itself, involves re-reading every data bit from the Flash card and checking it against every bit in the flash.img file.

5.3 Working Copy (file copy)

The Working Copy is a full copy of the directory tree of the Flash card or USB drive.

This means all files and directories are copied. Any file types can be copied. It provides a function similar to conventional backup software.

For the files on the Flash card to be recognised by PUMA, the card must be formatted with a FAT16 or FAT32 file system. The Working Copy disk uses an ISO9660 filing system and is recognised by most computing platforms. The system also implements the Joliet extension to the ISO 9660 standard which allows for long file names.

Cypher Technology Ltd 2008 17

Where RAW image files are detected, the system automatically converts them to a

JPEG compressed image file with a compression ratio of about 7:1. The file has the same root name as the original, so that dcn0005.nef becomes dcn0005nef.jpg. For most picture content it will not be possible to readily observe any difference in quality between the JPEG and RAW images. Where this feature is not required, it may be disabled (see above).

A wide range of RAW file formats are supported and these are listed in the Appendix.

5.4 Card and Disk Checksum

Puma produces a 32 bit checksum of the Flash card and Master Copy file. The checksum is a unique number derived from all the data on the card or from the whole image file on the Master Copy. As such the checksum will always change if any data changes are made within the file or on the card. The chance of two Flash cards, with different image data, of having the same checksum is 1 in 4,000,000,000.

The checksum of a Flash card or Master Copy can be found using the Menu functions

(see above).

5.5 Flash Card Wipe (Erasing)

As mentioned above, when a file is deleted the file data remains on the medium. This file may be un-deleted and the file’s data recovered. The only way to render the card safe from data recovery is to re-write the whole card with new data. Puma “Wipe Card” function writes binary zeros to the whole card. Also viruses may be present in the

Master Boot Record (MBR). During the wipe process the MBR is overwritten also and is recreated during the format operation.

5.6 System Architecture

Puma is based on a Linux platform and uses proprietary software. The proprietary nature of the software has allowed the transfer process to be tailored precisely to the needs of law enforcement and evidence gathering. For maximum reliability and security it contains no hard disk and boots from a read-only Flash file system.

5.7 Transfer Times

The Media Transfer Station uses a full height, high performance CD/DVD writer drive.

This type of drive provides transfer rates up to 20 Mbyte/sec compared with 8Mbyte/sec for laptop drives. Also, the larger size of the drive provides a higher reliability disk.

Further time is saved during the transfer as the separate tasks (Transfer, Verify and

Erase) are started automatically, one after the other. The user does not have to open separate applications for disk imaging, file copy, file verify, raw file conversion and Flash erase. Clearly for the user to run these five programs manually in sequence would require considerable time and perhaps more important, be prone to error. A single, automated process avoids these sources of error and saves time.

For reading, the maximum transfer rate (at he outside of the disk) is about 20

Mbytes/sec. A 4 Gbyte card can be copied in about 4 minutes.

Cypher Technology Ltd 2008 18

Master Creation

When making the Master disk, the whole contents of the Flash card are coped to the

CD/DVD. The transfer time is dependent on the Flash card size. A 4GByte card would take about 5 minutes to transfer.

Master Verify

This involves re-reading the Flash card and comparing the data with the disk image.

This takes about 4 minutes for a 4 Gbyte card.

Working Copy Creation

This involves only copying the files themselves and the time taken will depend on the amount of data contained in the files. A large RAW file of say 16 Mbytes would take around 1 second to transfer.

Where a JPEG is created from the RAW file this will take from a few seconds to a few tens of seconds per file depending on the size of the RAW file.

Flash Erasure

The erasing process involves writing a fixed binary pattern of data back to the Flash media so that the original data cannot be recovered or un-erased under any circumstances. This wiping process therefore depends on the write speed of the particular Flash card. Write speeds are commonly up to about 10 Mbytes/s which gives an erase time of about 6 minutes for a 4 Gbyte card.

Transfer Time for a Complete Automated Master and Working Copy

Example:

For a 4 Gbyte SD card with 6 x 16 Mbytes RAW files the transfer time would be:

Create Master 5 Mins

Master Verify 4 Mins

Create Working Copy

Erase Flash

Total

3 Mins (depends of RAW conversion speed)

6 Mins(Depends of Flash card type and brand)

18 Minutes

5.8 RAW File handling

RAW to JPEG converter

The system incorporates a RAW image file format converter. This automatically detects the type of RAW file present and converts it to a standard JPEG image file which is added to the Working Copy along with the original RAW format file. The JPEG will typically be about 1/7 th

the size of the RAW file, and so will not add greatly to storage requirements. This software is maintained and new formats are supported as they arise.

The JPEG file will have the same root name as the RAW file. For example, if the RAW image file is D94L0948.DCR the JPEG will be D94L0948DCR.JPG

The cameras currently supported by the converter are listed in Appendix 1.

6 Technical Support

6.1 System re-starting in the event of failure

Every effort has been made to allow PUMA cope gracefully with various fault conditions.

It is possible, however, that the system will temporally lock-out. If the system does not respond during use (please wait for 3 minutes during a transfer), then the system should be powered down by switching off at the rear panel. Remove the Flash card and re-start the system. The disk can only be ejected once the system is ready for use. In an emergency, when the system cannot be powered, the disk can be ejected by pushing hard with a blunt rod through the disk eject hole in the front panel.
