Interception of data and voice communications is a lawful obligation of telecommunications service providers. The demand for lawful interception solutions is generated by a number of stakeholders such as government regulators, law enforcement agencies (LEAs), and communication service providers to prevent crime, including fraud and terrorism. LEAs perform electronic surveillance as authorized by judicial or administrative orders while minimizing the violation of civil liberties and privacy to collateral users. Most of the countries have adopted lawful interception regulations. These regulations may vary from country to country. Lawful interception is the official legal access to private communications such as e-mail messages and telephone calls. Lawful interception allows companies to make their communications available to law enforcement officials when requested.

Video surveillance is the process of monitoring or observing the activities, behavior, or movements of an individual or a group to provide enhanced security. It is used by retail stores, government departments, hospitals, transportation and logistics companies,and law enforcement agencies to prevent criminal activities. Integration of the video surveillance solutions gives a centralized method for the enterprises to enhance their surveillance capabilities.During the past ten years, video surveillance solutions have changed in line with the advances in technology. The biggest development during the period was the shift from video home system (VHS) to DVD and high-resolution video. With the increased adoption of high-resolution video standards, there has been a huge demand for data storage.

2FA is a verification technique that uses two dissimilar factors. It is a combination of factors like a username and a password, an ATM card, or a biometric characteristic such as fingerprint.MFA is a security system that requires more than one type of authentication toverify the user's identity for login and transaction purposes.Primary layer (something the user knows): Personal identification number (PIN),pattern, and/or password Secondary layer (something the user has): Smart card, ID card, software token,hardware token, and/or phone-based token Tertiary layer (something the user is): Biometric identifiers such as facial recognition, fingerprint identification, and/or retinal pattern.The global 2FA market is in its maturity stage. The introduction of cloud-based authentication solutions will drive the demand for 2FA among small and medium-sized businesses (SMBs) because their implementation does not require any infrastructureand is cost-effective. Moreover, the surge in cyber attacks has compelled many sectors, such as government and healthcare, to adopt 2FA for enhanced security. This is expected to contribute to the market growth during the forecast period.

Virtual events are online exhibitions that include breakout sessions, video conferencing, web conferencing, collaboration tools, communication,and social networking. They are used in various sectors such as education, healthcare,hospitality, and finance and banking. Virtual events can be enabled on smartphones,desktops, laptops, and tablets. They can be used to announce the launch of newproducts, provide additional information to people, and obtain new vendors. The exhibit below represents the differences between physical events and virtual events.The report covers the present scenario and the growth prospects of the global virtual events market for the period 2017-2021. 

VR is a computer generated 3D environment, which engages the user in the virtual world by interacting with it. The user will be completely engaged in the environment and will be able to play around with virtual objects and also execute a series of actions.Augmented reality (AR) AR technology helps in blending the digital content with the physical world. Computer generated images are displayed by it in the user's field of vision, and relevant information about the objects is provided in the real world. The user can scan the physical real world environment and get an enhanced or augmented experience by adding virtual computer-generated information.

LPWAN technologies operate at a low cost, with immense power efficiency. A few examples of these technologies are Sigfox, machine-to-machine (M2M) Spectrum, and NWave. LPWAN is suitable for applications that require connecting widely scattered devices. A connected smoke detector can trigger a smoke alarm with absolute certainty using this technology.
