Big data is a term that not only describes a large Volume of data, but also includes Velocity, Verity, and Veracity with both structured and unstructured data format. Big data challenges include collecting data, data storage, data analysis, search, sharing, transfer, visualization, querying, updating and information privacy. Among the four Vs, veracity is still not remarkably addressed, particularly with the first challenge (data collection). Veracity basically refers to the biases, noise and abnormality in data. One question may arise, is the collected data that is being stored, transfer, and mined meaningful to the problem being analyzed? We have numerous applications of sensor networks, wireless networks, internet of things, and cyber physical systems. In the applications, devices need to collect data for the monitoring purposes and there are substantial works available to provide the data security and data privacy to transmit the collected data. However, there can be a big question, what would be the situation if low-quality, untrustworthy, meaningless, or undependable data are collected at the collection stage, and we use various communication protocols to transfer the data for monitoring purposes. Also, what would be the situation when you use various data privacy protocols at the communication stage, data privacy can be attacked at the collection stage. In this talk, I discuss these situations. Particularly, I focus on ensuring trustworthy data acquisition before transmission. I also discuss a few problems and possible solutions for the trustworthy data and its privacy at the collection stage.
