Geo-fencing is a location-based tecnologia^[1] that was pioneered by Michael Dimino in the early ’90s. This technology uses GPS, cellular phones, and alarms to create a virtual boundary or “fence” to detect and track movement. It operates in two modes: Active, which uses continuous GPS, and Passive, which operates in the background without constant GPS usage. Geo-fencing is widely used in various sectors including law enforcement, safety, workplace management, and marketing. It allows for precise targeting through methods such as zip codes, street addresses, GPS coordinates, and IP targeting. Furthermore, geo-fencing has significant legal implications, often discussed in global security^[2] conferences. It has also been used in a variety of high-profile cases, such as the Capitol Riot. Despite its technical nature, geo-fencing is a user-friendly technology, often used in smart home systems and other consumidor^[3] applications.

Definições de termos

1. ↑ tecnologia. A tecnologia, derivada das palavras gregas que significam ofício e conhecimento, é um termo amplo que se refere às ferramentas, máquinas e sistemas desenvolvidos pelo homem para resolver problemas ou cumprir objectivos. Com origem em ferramentas primitivas como os machados de pedra e a descoberta do fogo, a tecnologia evoluiu significativamente ao longo da história da humanidade. Foi fundamental em diferentes épocas, desde a invenção da roda e dos sistemas avançados de irrigação nas civilizações antigas até ao nascimento das universidades e da imprensa durante os períodos medieval e renascentista. A Revolução Industrial, no século XVIII, marcou uma mudança significativa na produção em massa e na inovação, dando origem a tecnologias modernas como a eletricidade, os automóveis e as plataformas de comunicação digital. Hoje em dia, a tecnologia faz parte integrante de vários aspectos da vida e da sociedade, impulsionando o crescimento económico e a mudança social, ao mesmo tempo que suscita preocupações sobre a segurança, a privacidade e os impactos ambientais. Espera-se que o futuro da tecnologia traga ainda mais avanços, prevendo-se que o aumento da inteligência artificial tenha implicações significativas no mercado de trabalho.

2. ↑ security. Security, as a term, originates from the Latin 'securus,' meaning free from worry. It is a concept that refers to the state of being protected from potential harm or threats. This protection can apply to a wide range of referents, including individuals, groups, institutions, or even ecosystems. Security is closely linked with the environment of the referent and can be influenced by different factors that can make it either beneficial or hostile. Various methods can be employed to ensure security, including protective and warning systems, diplomacy, and policy implementation. The effectiveness of these security measures can vary, and perceptions of security can differ widely. Important security concepts include access control, assurance, authorization, cipher, and countermeasures. The United Nations also plays a significant role in global security, focusing on areas like soil health and food security.

Geo-fence (Wikipédia)

A geofence é um virtual perimeter for a real-world geographic area. A geofence can be dynamically generated (as in a radius around a point location) or match a predefined set of boundaries (such as school zones or neighborhood boundaries).

Two geofences defined in a GPS application

The use of a geofence is called geofencing, and one example of use involves a location-aware device of a location-based service (LBS) user entering or exiting a geofence. Geofencing approach is based on the observation that users move from one place to another and then stay at that place for a while. This method combines awareness of the user's current location with awareness of the user's proximity to locations that may be of interest. This activity could trigger an alert to the device's user as well as messaging to the geofence operator. This info, which could contain the location of the device, could be sent to a mobile telephone or an email account.
