Introduction
The EPSON Image Authentication System™
(IAS) lets you check the authenticity of photos
taken with your EPSON PhotoPC®
700 or
EPSON PhotoPC 750Z camera. IAS detects
when even a single bit of digital data in a picture
has been altered. Because IAS doesn’t change the
file format, it has no affect on your ability to
store and display pictures, or to use them in
other applications.
Important:
Your software license agreement permits
you to upload the IAS software to only one
EPSON digital camera per software copy
or license purchased.

■IBM®compatible PC with a 486 or higher

Installing IAS
Follow these steps to install IAS:
1. Insert the EPSON Image Authentication
System CD into your CD-ROM drive.
2. Click the Start button, then click Run.
3. Type
D:
\SETUP (where
D
is the letter of the
CD-ROM drive) and click OK to start the
installation program.
4. Follow the instructions on your screen.
Uploading IAS to Your Camera
EPSON Image Authentication System only
verifies the authenticity of pictures taken after
the IAS program is uploaded to your camera.
You can use this procedure both to upload IAS
to your camera and to verify that IAS is loaded
on a camera.
Before you start, make sure you have the serial
cable that came with your camera. Also, either
use an AC adapter or make sure your camera has
a fully charged set of batteries.

Turn off the camera and LCD screen, then
follow these steps:
1. Locate you computer’s serial port.
Note:
You may have two serial ports labeled
COM1 and COM2, or the ports may be
labeled with icons. If you have two ports,
use COM1 to connect your camera.
2. Line up the serial connector on the cable
with your computer’s serial port, and insert
the connector. Then tighten the screws.

3. Open the connector cover on the side of the
camera.
4. Line up the cable’s connector with the
camera’s serial port. Then insert the
connector.
5. Turn on the camera.
Note:
If you have problems connecting to the
COM port you’ve selected, check your
computer’s COM port configuration and
try again. If you’re using batteries instead
of an AC adapter, make sure your batteries
are fully charged.

connection.

disconnect the first camera and connect the
second. Turn the second camera on, then
click Test Connection to make sure the
camera is properly connected. The software
uploads automatically to the second camera.

your camera when you’re finished.
Any pictures you take with your camera from
this point on can be checked by IAS for
authenticity.

In the unlikely event your camera needs to
be repaired, you will need to upload IAS
again.

Verifying Pictures
After you’ve loaded IAS on a camera, any
pictures you take will contain an invisible,
encrypted “fingerprint.” IAS uses this fingerprint
to check the integrity of a picture. You can check
a single picture or verify several pictures at once.
(Transfer your photos to the computer before
starting this procedure.)
To verify a picture:

Image Authentication System, and click
