Security has always been one of the key elements within the mobile device market. As mobile device usage, particularly in smartphones, increases, there is a greater need for better device security and integrity. Previously, a high level of importance was placed on security software solutions, with very little emphasis on hardware security solutions. Each chipset company has its own security solutions and ARM’s TrustZone security technology is emerging as the leader in the smartphone sector. Additionally, the growing popularity of NFC will soon have a substantial impact on the mobile device market as more consumers demand smartphone contactless payment capabilities. Furthermore, biometric sensors have been on the fringe in the mobile device market for several years, but have yet to see any mass incorporation with a mobile handset OEM. This study offers a comprehensive overview of the market for hardware security and mobile operating systems, with a comparison of the security ecosystems supporting various smartphone operating systems. Revenue and trends are forecast for embedded chipset security solutions, NFC, and biometric sensors. The report also provides further details on the market for biometric sensors by smartphones, tablets, and PCs and laptops. The study also presents OS subscribers and enterprise subscribers by OS provider and key regions.
