New Brazil Law Restricts Use of Smartphones in Elementary and High Schools

Brazil's President Luiz Inácio Lula da Silva on Monday signed a bill restricting the use of smartphones at school, following a global trend for such limitations.

The move will impact students at elementary and high schools across the South American nation starting in February. It provides a legal framework to ensure students only use such devices in cases of emergency and danger, for educational purposes, or if they have disabilities and require them.

"We cannot allow humanism to be replaced by algorithms," Lula said in a closed ceremony at the presidential palace in the capital, Brasilia, adding that the bill "acknowledges the work of every serious person in education, everyone who wants to take care of children and teenagers in this country."

In May, Fundacao Getulio Vargas, a leading think-tank and university, said Brazil had more smartphones than people, with 258 million devices for a population of 203 million Brazilians. Local market researchers said last year that Brazilians spend 9 hours and 13 minutes per day on screens, one of the world's highest figures.

Education minister Camilo Santana told journalists that children are going online at early ages, making it harder for parents to keep track of what they do, and that restricting smartphones at school will help them.

The bill had rare support across the political spectrum, both from allies of leftist Lula and his far-right foe, former President Jair Bolsonaro.

Many parents and students also approved the move. A survey released in October by Brazilian pollster Datafolha said that almost two-thirds of respondents supported banning the use of smartphones by children and teenagers at schools. More than three-quarters said those devices do more harm than good to their children.

"(Restricting cellphones) is tough, but necessary. It is useful for them to do searches for school, but to use it socially isn't good," said Ricardo Martins Ramos, 43, father of two girls and the owner of a hamburger restaurant in Rio de Janeiro. "Kids will interact more."

His 13-year-old daughter Isabela said her classmates struggled to focus during class because of their smartphones. She approved the move, but doesn't see it as enough to improve the learning environment for everyone.

"When the teacher lets you use the cellphone, it is because he wants you to do searches," she said. "There's still a lot of things that schools can't solve, such as bullying and harassment."

As of 2023, about two-thirds of Brazilian schools imposed some restriction on cellphone use, while 28% banned them entirely, according to a survey released in August by the Brazilian Internet Steering Committee.

The Brazilian states of Rio de Janeiro, Maranhao and Goias have already passed local bills to ban such devices at schools. However, authorities have struggled to enforce these laws.

Authorities in Sao Paulo, the most populous state in Brazil, are discussing whether smartphones should be banned both in public and private schools.

Gabriele Alexandra Henriques Pinheiro, 25, works at a beauty parlor and is the mother of a boy diagnosed with autism spectrum disorder. She also agrees with the restrictions, but says adults will continue to be a bad example of smartphone use for children.

"It is tough," she said. "I try to restrict the time my son watches any screens, but whenever I have a task to perform I have to use the smartphone to be able to do it all," she said.

Institutions, governments, parents and others have for years associated smartphone use by children with bullying, suicidal ideation, anxiety and loss of concentration necessary for learning. China moved last year to limit children’s use of smartphones, while France has in place a ban on smartphones in schools for kids aged six to 15.

Cellphone bans have gained traction across the United States, where eight states have passed laws or policies that ban or restrict cellphone use to try to curb student phone access and minimize distractions in classrooms.

An increasing number of parents across Europe who are concerned by evidence that smartphone use among young kids jeopardizes their safety and mental health.

A report published in September by UNESCO, the United Nations Educational, Scientific and Cultural Organization, said one in four countries has already restricted the use of such devices at schools.

Last year in a US Senate hearing, Meta CEO Mark Zuckerberg apologized to parents of children exploited, bullied or driven to self-harm via social media. He also noted Meta’s continued investments in "industrywide" efforts to protect children.

How Safe Is Signal Messaging App Used by Trump Aides to Share War Plans?

Top Trump administration officials used messaging app Signal to share war plans and mistakenly included a journalist in the encrypted chat, spurring calls by Democratic lawmakers for a congressional investigation into the security breach.

Under US law, it can be a crime to mishandle, misuse or abuse classified information, though it is unclear whether those provisions might have been violated in this case.

Below are some of the main facts about Signal:

HOW SAFE IS IT?

Signal is an open-source and fully encrypted messaging service that runs on centralized servers maintained by Signal Messenger.

The only user data it stores on its servers are phone numbers, the date a user joined the service, and the last login information.

Users' contacts, chats and other communications are instead stored on the user's phone, with the possibility of setting the option to automatically delete conversations after a certain amount of time.

The company uses no ads or affiliate marketers, and doesn't track users' data, as stated on its website.

Signal also gives users the possibility to hide their phone number from others and use an additional safety number to verify the safety of their messages, it adds.

Signal does not use US government encryption or that of any other governments, and is not hosted on government servers.

The messaging app has a "stellar reputation and is widely used and trusted in the security community", said Rocky Cole, whose cybersecurity firm iVerify helps protect smartphone users from hackers.

"The risk of discussing highly sensitive national security information on Signal isn't so much that Signal itself is insecure," Cole added.

Actors who pose threats to nation states, he said, "have a demonstrated ability to remotely compromise the entire mobile phone itself. If the phone itself isn't secure, all the Signal messages on that device can be read."

HOW DOES SIGNAL WORK?

Signal is a secure messaging service that uses end-to-end encryption, meaning the service provider cannot access and read private conversations and calls from users on its app, therefore guaranteeing its users' privacy.

Signal's software is available across platforms, both on smartphones and computers, and enables messaging, voice and video calls. A telephone number is necessary to register and create an account.

Unlike other messaging apps, Signal does not track or store user data, and its code is publicly available, so security experts can verify how it works and ensure it remains safe.

Signal President Meredith Whittaker on Tuesday defended the app's security: "Signal is the gold standard in private comms."

She added in a post on X: "WhatsApp licenses Signal’s cryptography to protect message contents for consumer WhatsApp."

WHO FOUNDED SIGNAL?

Signal was founded in 2012 by entrepreneur Moxie Marlinspike and Whittaker, according to the company's website.

In February 2018, Marlinspike alongside WhatsApp co-founder Brian Acton started the non-profit Signal Foundation, which currently oversees the app.

Acton provided an initial funding of $50 million. Acton left WhatsApp in 2017 due to differences around the use of customer data and targeted advertising.

Signal is not tied to any major tech companies and will never be acquired by one, it says on its website.

WHO USES SIGNAL?

Widely used by privacy advocates and political activists, Signal has gone from an exotic messaging app used by dissidents to a whisper network for journalists and media, to a messaging tool for government agencies and organizations.

Signal saw "unprecedented" growth in 2021 after a disputed change in rival WhatsApp's privacy terms, as privacy advocates jumped off WhatsApp on fears users would have to share their data with both Facebook and Instagram.

Reuters lists Signal as one of the tools tipsters can use to share confidential news tips with its journalists, while noting that "no system is 100 percent secure".

Signal's community forum, an unofficial group which states that its administration is composed of Signal employees, also lists the European Commission as a user of the tool. In 2017, the US Senate Sergeant at Arms approved the use of Signal for Senate staff.

"Although Signal is widely regarded as offering very secure communications for consumers due to its end-to-end encryption and because it collects very little user data, it is hard to believe it is suitable for exchanging messages related to national security," said Ben Wood, chief analyst at CCS Insight - alluding to the breach involving top Trump aides discussing plans for military strikes on Yemeni Houthi militants.

Google's message services Google Messages and Google Allo, as well as Meta's Facebook Messenger and WhatsApp, use the Signal Protocol, according to Signal's website.
