Vehicle speed is an important parameter that finds tremendous application in traffic control identifying over speed vehicles with a view to reducing accidents. Many methods, such as using RADAR and LIDAR sensors have been proposed. However, these are expensive, and their accuracy is not quite satisfactory. In this paper, a video-based vehicle speed determination method is presented. The method shows satisfactory performance on standard data sets and gives that error rate of velocity estimation is within 10%.
Steganography is the art of hiding information in ways that prevent the detection of hidden messages. It includes a vast array of secret communications methods that conceal the message's very existence. These methods include invisible inks, microdots, character arrangement, digital signatures, covert channels, and spread spectrum communications. In this research we have proposed a simple and effective way to hide data in audio file with 256 bit AES encryption based on Least Significant Bits technique. This approach can hide not only text message but also any type of files currently used e.g. .jpg, .pdf, .mp3, mpeg4 etc in a wav audio file.
This paper presents a reliable method for detecting human faces in color images. The system is based on the visual information of the face and is commenced with the detection of face regions by connected component analysis of the skin color segmentation of images in HSV,YC B C R ,YIQ color model and the Fuzzy membership function. The Fuzzy Membership function is applied to search for possible face regions in an image. The proposed method is robust in that it can deal with illumination changes and moderate rotations.
Cryptography is one of the major elements in data security and communication security. It is a technique of securing the communication by preventing third parties. A hybrid cryptosystem is the special set of rules using multiple ciphers or a combination of a series of well-defined steps that can be followed as a procedure of different types together by taking best advantage of each cipher. In this cryptosystem, a random secret key is generated used as a symmetric cipher which is required for all parties. Then the system encrypts this key via an asymmetric cipher using the recipient's public key. DNA cryptography is a new optimistic field in cryptography which hides the data in terms of DNA sequence to make it secured. The OTP (one-time pad) is an encryption technique in which a plaintext is paired with a one-time pre-shared key which is equal to or longer than the size of the message being sent. In RSA, a public key is used for encryption which specifies the transformation of plaintext into ciphertext and this encryption key differs from the decryption key which is kept private to secure data transmission. In this paper, a hybrid cryptosystem is proposed using DNA, the generic OTP technique and RSA to ensure high security in three levels. This method is very efficient for encrypting data, hiding text and preventing attacks. General TermsCryptosystem, Hybridization.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
