This document discusses a project to implement encryption and decryption of images using OpenGL. The objectives are to study JPEG image file architecture, develop an application using OpenGL for image encryption, and ensure secure password handling. The application aims to protect sensitive images from unauthorized access during transfer or at destination. It allows encrypted images to only be decrypted by the application itself using a password. The project provides easy-to-use and fast encryption/decryption capabilities along with more secure data transmission.

2. WHAT IS ENCRYPTION?
ENCRYPTION IS DEFINED AS MODIFIED INFORMATION
INTO A SPECIAL CODE, ESPECIALLY IN ORDER TO
PREVENT UNAUTHORIZED USERS TO HAVE ACCESS TO
THE INFORMATION.

3. WHAT IS DECRYPTION?
DECRYPTION IS THE PROCESS OF TAKING ENCODED OR
ENCRYPTED TEXT OR OTHER DATA AND CONVERTING IT
BACK INTO TEXT THAT YOU OR THE COMPUTER CAN
READ AND UNDERSTAND.

4. HOW IT WORKS?

6. OBJECTIVES
1.THE FIRST IS TO STUDY THE ARCHITECTURE OF IMAGE FILE. THE
STUDY IS FOCUSED TO JPG FILE TYPE BECAUSE IT IS ONE OF THE
MOST POPULAR IMAGE FORMAT USED.
2.THE SECOND OBJECTIVE IS TO DEVELOP AN APPLICATION USING
OPENGL THAT CAN BE USED TO ENCRYPT AN IMAGE FILE. THIS
APPLICATION MUST BE SIMPLE, EASY TO USE, AND POWERFUL.
3.THE LAST OBJECTIVE OF THIS THESIS IS TO MAKE SURE THAT THE
PASSWORD HANDLING PROCESS IS NO CARELESSLY IMPLEMENTED.
4.THIS APPLICATION WILL AFFECT ITS INTEGRITY AND REPUTATION. ALL
OF THE OBJECTIVES ACHIEVED GIVE A GOOD OUTCOME IN PROJECT.

7. OUTCOMES
THE APPLICATION HAS THE CAPABILITY TO PROTECT
SENSITIVE IMAGE FILE FROM BEING EXPOSED TO THE
UNAUTHORIZED USERS WHILE BEING TRANSFERRED OR WHEN
IT REACHES ITS TARGET DESTINATION.
THE MODIFICATION PERFORMED BY THE APPLICATION
WHEREBY ONCE THE IMAGE FILE IS ENCRYPTED BY THE
APPLICATION, IT CAN ONLY BE RETRIEVED BACK OR
DECRYPTED BY ITSELF ONLY.
 THE PROJECT ALSO PROVIDES USER WITH THE EASE OF USE
CONCEPT AND FASTER PROCESSING TIME. IT ALSO
INTRODUCES SAFER AND POWERFUL DATA.

8. ADVANTAGES
PROTECT IMAGE COMPLETELY
ACHIEVE SECURITY ON ALL DEVICES
TRANSMIT SECURELY
