OBJECTIVE: B. DECRYPTION METHOD:
In our wander estimation is proposed to hide a
puzzle picture inside CVR picture to guarantee the
insurance of the photo.
Steganography Imaging System (SIS) is a structure
that is fit for covering the data inside the photo. The
structure is using two layers of security with a particular
true objective to keep up data assurance.
Using LSB algorithm we are replacing the list
significant bit of cover image with a secret image.

PROBLEM DEFINITION: message.
The purpose of our wander is to scramble and
unscramble the stego picture. The stego picture is the PSOC ARCHITECTURE:

collection of switch capacitor, operation amp,
comparator, ADC, DAC, and advanced channel pieces,
permitting complex simple flag streams.

CPU SUB SYSTEM:

PSoC offers a refined CPU subsystem with SRAM, EE
PROM, and blaze memory, numerous center choices and
an assortment of fundamental framework assets
including:
 Internal main and low-speed oscillator
 Connectivity to external crystal oscillator for
precision, programmable clocking
 Sleep and watchdog timers
 Multiple clock sources that include a PLL Fig. 4.3 Result Image

concluded that the steganography can be effectively used
to hide data or image into another image without any
loss.
The main advantage of our project is that any size of
image can be hided through LSB algorithm with high
speed of transmission by using PSoC kit.
