MATLAB code of AES Encryption and Decryption of Text

Nowadays Fast evaluation of digital data exchange is occurring. Due to that security of information is much important in data storage and transmission process. Security of internet banking account passwords, email accounts password etc. requires text protection in digital media. The National Institute of Standards and Technology (NIST) have initiated a process to develop Federal Information Processing Standard (FIPS) which should be most flexible, secure and fast which can replace Data Encryption standard. This new standard is recognized by name Advanced Encryption Standard (AES). Features of data are depending on its types. Because of which same encryption techniques cannot be used for all types of data. However, with few variations in method AES can be used to protect text.

MATLAB code of Fractal Image Compression

Hello, friends today I would like to post one more project in the field of image compression. The concept is image compression using fractal transform. Fractal image compression is a new technique for encoding images compactly. It builds on local self-similarities within images. Image blocks are seen as rescaled and intensity transformed approximate copies of blocks found elsewhere in the image. This yields a self-referential description of image data, which when decoded shows a typical fractal structure. 

MATLAB code of Palm print Recognition using Gabor filter

Palm print is becoming most essential and relatively large biometric identifier as compared to other biometric traits such as fingerprint, iris, face, retina, signature, and DNA. Palm print identification has various advantages 
(1) low-resolution imaging 
(2) stable line feature 
(3) high user acceptance. 
Earlier techniques like fingerprint identification and iris and retina reorganization require high accuracy but there are some problems with these prior technologies. In palm print feature extraction considered geometrical features are wrinkles, ridges and principle lines singular point, textures, etc. Palm print authentication can be done in two way i.e. Online and offline.

MATLAB code of Image Forgery Detection

Hello, Guys today posting a new project in the field of information security. The project is about image forgery detection. Forgery is an illegal means of manipulating images or documents without prior access. Images are tampered for different reasons either to create false evidence or to earn money in an illegal way. A pictorial representation of the image conveys a much better idea than the words of humans. Due to the progression in digital technology, images are processed using several tools like Adobe Photoshop, GIMP and Corel Paint Shop and they ended up with a threat to the authenticity of digital images. Generally, image manipulations are of two types 
a) Allowed manipulation 
b) Malignant manipulation.

MATLAB code of Iris recognition using phase based Image Matching

Hello, Guys posting a new project based on biometric detection. The title is Iris recognition using phase-based Image Matching. A Biometric system provides automatic recognition of an individual based on some sort of unique feature or characteristic possessed by the individual. Biometric systems have been developed based on fingerprints, facial features, voice, hand geometry, handwriting, the retina, and the one presented in this post, the iris. Biometric systems work by first capturing a sample of the feature, such as recording a digital sound signal for voice recognition or taking a digital color image for face recognition.

MATLAB code of Steganography scheme based on Contourlet Transform

Hello, friends today I would like to post one project in the field of information security. the title of the project is a Steganography scheme based on Contourlet Transform. In this method, embedding is done in a contourlet transform domain. The contourlet coefficients with the larger magnitude that correspond to the edges are selected for embedding. This selection is due to less sensitivity of human eyes to non-smooth regions. Each bit of secret data is embedded by exchanging the value of two coefficients in a 4 times 4 block of a contourlet subband. The proposed method is examined with two strong steganalysis algorithms and the results show that we could successfully embed data in a cover image.  

Elliptical Curve Cryptography (ECC) Encryption & Decryption MATLAB code

Hello, Friends today I would like to post one project in the field of information security. The title of the project is Elliptical Curve Cryptography (ECC) Encryption & Decryption. ECC is a way to encrypt data so that only specific people can decrypt it. This has several obvious real-life use cases, but the main usage is in encrypting internet data and traffic. For instance, ECC can be used to ensure that when an email is sent, no one but the recipient can read the message.

MATLAB code of Abandoned and Removed objects from complex videos

Hello, Friends today I would like to pose one more project in the field of video processing. The project is about Abandoned and Removed objects from complex videos. this project includes the following concepts, the mixture of Gaussians background subtraction method is employed. Without using any tracking or motion information, static objects were detected by using the same Gaussian mixture model, and then were classified into abandoned or removed objects by segmenting and comparing the surrounding areas of the background model and the foreground image.
