    In Wireless sensor networks (WSNs), All communications between different nodes are sent out in a broadcast fashion. These networks are used in a variety of applications including military, environmental, and smart spaces. Sensors are susceptible to various types of attack, such as data modification, data insertion and deletion, or even physical capture and sensor replacement. Hence security becomes important issue in WSNs. However given the fact that sensors are resources constrained, hence the traditional intensive security algorithms are not well suited for WSNs. This makes traditional security techniques, based on data encryption, not very suitable for WSNs. This paper proposes Linear Kolmogorov watermarking technique for secure data communication in WSNs. We provide a security analysis to show the robustness of the proposed techniques against various types of attacks. This technique is robust against data deletion, packet replication and Sybil attack

    This thesis records the research on watermarking techniques to address the issue of copyright protection of the scalar data in WSNs and image data in WMSNs, in order to ensure that the proprietary information remains safe between the sensor nodes in both. The first objective is to develop LKR watermarking technique for the copyright protection of scalar data in WSNs. The second objective is to develop GPKR watermarking technique for copyright protection of image data in WMSN

    Watermarking technique for wireless multimedia sensor networks: A state of the art

    Get PDF
    Wireless multimedia sensor networks (WMSNs) are an emerging type of sensor network which contain sensor nodes equipped with microphones, cameras, and other sensors that produce multimedia content. These networks have the potential to enable a large class of applications ranging from military to modern healthcare. Multimedia nodes are susceptible to various types of attack, such as cropping, compression, or even physical capture and sensor replacement. Hence, security becomes an important issue in WMSNs. However, given the fact that sensors are resource constrained, the traditional intensive security algorithms are not well suited for WMSNs. This makes the traditional security techniques, based on data encryption, not very suitable for WMSNs. Watermarking techniques are usually computationally lightweight and do not require much memory resources. These techniques are being considered as an attractive alternative to the traditional techniques, because of their light resource requirements. The objective of this paper is to present a critical analysis of the existing state-of-the-art watermarking algorithms developed for WMSNs

    Wireless multimedia sensor networks (WMSNs) are an emerging type of sensor networks which contain sensor nodes equipped with microphones, cameras, and other sensors that producing multimedia content. These networks have the potential to enable a large class of applications ranging from military to modern healthcare. Since in WMSNs information is multimedia by nature and it uses wireless link as mode of communication so this posse?s serious security threat to this network. Thereby, the security mechanisms to protect WMSNs communication have found importance lately. However given the fact that WMSN nodes are resources constrained, so the traditionally intensive security algorithm is not well suited for WMSNs. Hence in this research, we aim to a develop lightweight digital watermarking enabled techniques as a security approach to ensure secure wireless communication. Finally aim is to provide a secure communication framework for WMSNs by developing new
