A new image authentication technique using random sequence based secret sharing scheme with a data repair capability is proposed. For each block of image, an authentication signal is generated together with the binarized block content, which is transformed into several shares using the secret sharing scheme. The parameters which have been involved in the algorithm, are carefully selected so that the...
Secure transmission of information in MANET is a challenging task due to its fundamental characteristic like open shared wireless medium, physical vulnerabilities of the devices, infrastructure less, devices' limited processing power, limited bandwidth etc. In this paper, we introduce a secure version the AODV routing protocol. The proposed method used the authentication technique like nested message...
Biometric methods are individual characteristics that cannot be used by imposters to enter in a secured system. Key stroke dynamics is a biometric utilizing the typing rhythm of the user. Key stroke dynamics is classified in two classes: (a) Fixed text based and (b) Free text based. We are proposing a novel technique for free text keystroke dynamics. In this method, keys are classified into two halves...
