<P> A recent study by Ericsson regarding the adoption of IoT among Danish companies, has suggested that many are struggling "to pinpoint exactly where the value of IoT lies for them". A company must identify where the value of IoT lies in order to capture it, otherwise non-action is the consequence . This indicates that a major roadblock to IoT adoption is not technical but analytical in nature . </P> <P> According to a recent study by Noura Aleisa and Karen Renaud at the University of Glasgow, "the Internet of things' potential for major privacy invasion is a concern" with much of research "disproportionally focused on the security concerns of IoT ." Among the "proposed solutions in terms of the techniques they deployed and the extent to which they satisfied core privacy principles", only very few turned out to be fully satisfactory . Louis Basenese, investment director at Wall Street Daily, has criticized the industry's lack of attention to security issues: </P> <P> "Despite high - profile and alarming hacks, device manufacturers remain undeterred, focusing on profitability over security . Consumers need to have ultimate control over collected data, including the option to delete it if they choose...Without privacy assurances, wide - scale consumer adoption simply won't happen ." </P> <P> In a post-Snowden world of global surveillance disclosures, consumers take a more active interest in protecting their privacy and demand IoT devices to be screened for potential security vulnerabilities and privacy violations before purchasing them . According to the 2016 Accenture Digital Consumer Survey, in which 28000 consumers in 28 countries were polled on their use of consumer technology, security "has moved from being a nagging problem to a top barrier as consumers are now choosing to abandon IoT devices and services over security concerns ." The survey revealed that "out of the consumers aware of hacker attacks and owning or planning to own IoT devices in the next five years, 18 percent decided to terminate the use of the services and related services until they get safety guarantees ." This suggests that consumers increasingly perceive privacy risks and security concerns to outweigh the value propositions of IoT devices and opt to postpone planned purchases or service subscriptions . </P>
