Efficient and secure data sensing, storage and processing play pivotal roles in the current information age. State-of-the-art nanoelectronic technology based very-large-scale-integration (VLSI) systems caters to the needs of efficient sensing, storage, and computing. At the same time, efficient algorithms and software used for faster analysis and retrieval of desired information are becoming increasingly important. Big data which are large, complex data sets, are now a part of the Internet world. Storing and processing needs of the enormous amount of structured and unstructured data are getting increased challenging. At the same time, Internet of Things (IoT) and cyber-physical systems (CPS) have been evolving with the simultaneous development of hardware and software. The performance and efficiency of the present as well as the future generation of computing and information processing systems are largely dependent upon advances in both hardware and software. The primary objective of iNIS is aimed to provide a platform for both hardware and software researchers to interact under one umbrella for further development of efficient and secure information processing circuits and systems. iNIS 2015 is sponsored by IEEE Computer Society (IEEE-CS) under the technical committee on VLSI (TCVLSI) and technically co-sponsorship by IEEE Circuits and Systems Society (IEEE-CAS) as well as IEEE Council on EDA (IEEE-CEDA).
