Thesis

The spread of using of WebP image format on the Internet, especially on social media and conversation programs, so when sending them repeatedly do not raise doubt, which made it a point of strength in the exploiting this feature by data security field.In this thesis, an integrated system was proposed to protect secret messages using steganography technique to hiding the secret messages within WebP

Biometrics is automated methods of recognizing an individual based on a physiological or behavioral characteristic. Biometric system consists of two subsystems; one for enrollment and the second is for recognition. In enrollment, used three biometric samples used to create user’s main template.

Multiagents technology took a significant role in the field of decision making and machine learning for solving complex problems in the real world. They simulate human ability to decision making where they have ability to reasoning and behave autonomously to solve problems or to support human user.In this thesis, a classification system using hierarchal multi agent's technology based on neural network and fuzzy logic is introduced,where each agent is implemented as a neural network (trained using back propagation learning algorithm).

Fingerprints are the oldest and most broadly used form of biometric identification. Everyone is known to have unique, immutable fingerprints.Fingerprint identification and recognition are considered popular technique in many security and law enforcement applications. Many systems rely on the matching of fingerprints using various methods and algorithms based on find position and orientation of ridge endings and bifurcations within the fingerprint image in both levels (level 2 and level 3).
