Abstract	Distributed imaging using sensor arrays has grown rapidly over past several years. Because image data is characterized by is high volume, an architecture of two tiered visual sensor network is proposed, where storage nodes gather image data from nearby sensors and process sink's query to transmit a time-specific image. However the importance of storage nodes is attractive to attackers. In this paper, we propose a TransSec protocol to prevent attackers from deleting or distorting a time-specific image. To preserve privacy, we use a binary quadratic equation based technique to encode each image timestamp such that attackers cannot delete sensitive images without knowing their exact timestamp. To preserve integrity, we propose a new checksum chain that allows a sink to verify whether the result of a query contains exactly the data items and recover missing data items.
