Government efforts to access private communications are nothing new. In decades past, such attempts at prying were often justified on national security grounds.
However, policymakers today point to child safety and disinformation as reasons to limit privacy protections. Established democracies are often leading this charge, inadvertently paving the way for the world’s autocrats.
Yet people around the world are not taking these policies lying down. They speak out, using events such as Global Encryption Day to highlight the importance of privacy and security, not just for themselves, but for their communities and societies.
As vociferous opposition continues to stymie government efforts to expand surveillance powers, it has become clear that public pressure works.
Encryption, which scrambles digital data so that it can be read only by someone with the means to decode it, has become ubiquitous, because it keeps information confidential and secure while authenticating the identity of the person with whom one is communicating.
Today, billions of people use encryption to send digital messages and e-mails, transfer money, load Web sites and protect their data. The gold standard in security is “end-to-end” encryption (E2EE), as only the participants have access to the data — not even the service provider can decipher it.
Despite its immense value and global appeal, encryption is under threat worldwide. It is used by law-abiding citizens to protect themselves, but also by bad actors to hide their malicious activities. For this reason, law enforcement authorities oppose encryption designs, especially E2EE, that prevent them from accessing data.
Yet even after decades of research, there is still no known way to grant law enforcement access without undermining encryption’s privacy and security features. The makers of encrypted devices and services have therefore resisted calls to build in “backdoor” government access, which would make all of their users more vulnerable.
The harmful online activities that concern police do not happen only in encrypted spaces. Hate speech, disinformation and other objectionable content remain a pernicious problem on social-media platforms and other sites, motivating a worldwide legislative push to force tech companies to improve their services.
For example, the British Parliament recently passed the Online Safety Bill after several turbulent years during which pressure from civil society changed its scope significantly. The final version focuses mainly on the removal of illegal content and mitigating risks to children.
Yet the bill still has serious flaws. For example, Parliament failed to include language safeguarding encryption. Moreover, the law gives the British Office of Communications (Ofcom), which regulates information exchange, the authority to compel social media platforms and messaging services to mass scan their users’ files and communications for evidence of child sexual abuse.
No one contests that fighting child exploitation is immensely important, but Ofcom’s power covers E2EE messaging services, which by definition cannot be accessed by service providers. Thus, the only way these services could comply with an Ofcom order is by making fundamental changes to their encryption design.
In other words, the bill gives Ofcom the power to force service providers to undermine their own encryption. Apple, Meta and Signal have all promised to pull their E2EE apps from the UK rather than comply with any government order to diminish their users’ privacy and security.
In response, Ofcom has publicly vowed not to use its new authority, at least for now.
It did so with good reason: Important bodies have concluded that scanning technologies are not sufficiently accurate, would limit fundamental rights and would likely fail the proportionality test — the disadvantages would outweigh the advantages.
Furthermore, criminals could easily circumvent these controls by encrypting content using a separate application. Ofcom would be wise to tread carefully, lest it risk the privacy and security of Internet users for the sake of unproven and potentially ineffective technologies.
Ofcom’s (supposed) forbearance recalls Australian authorities’ conduct since the passage of a contentious 2018 law granting new governmental powers to compel communications providers to add backdoor access to their products. Civil society and cybersecurity experts raised alarms about the law’s dangers for privacy and security, and legislators said the bill was flawed, but it passed anyway.
Five years later, not a single compulsory notice has been issued. This might reflect a deliberate choice: Exercising such a power risks political blowback. Wield the sword too enthusiastically and it might be taken away; better to keep it sheathed in favor of other, less controversial tools.
Then again, government forbearance might also indicate that the controversial new power was unnecessary in the first place.
Public scrutiny of government powers keeps them in check. That is how a democracy is meant to work. In promising not to use its new tool, Ofcom appears to have grasped that the government’s legitimacy is at stake.
However, as the UK bill inspires similar legislation in other countries, some of which are less democratic and have a track record of weaponizing digital technologies against their citizens, this nuance is likely to be lost.
The first test will come in the EU, where legislators are fighting over a draft regulation to expand tech companies’ child safety obligations. Like the British bill, the proposed Child Sex Abuse Regulation (CSAR) has already gone through numerous revisions, as member states lock horns over protecting E2EE.
Derisively called “chat control,” the draft CSAR has been widely decried for potentially forcing European service providers to scan all public and private communications, which would amount to an illegal general monitoring obligation.
Recent reporting stoked these concerns by revealing that the European Union Agency for Law Enforcement Cooperation, requested unlimited access to and use of the data produced beyond the purposes identified in the regulation; it appears to have no intention of restraining itself.
Continued public pressure is necessary to push for reform of “the most criticized draft EU law of all time.”
If government surveillance is a concern in an established democratic entity such as the EU, what hope is there for beleaguered democracies such as Turkey, India and Brazil, much less autocracies?
Fortunately, the public movement in support of encryption is growing, with advocacy groups such as the Global Encryption Coalition leading the charge.
By engaging with civil society, technologists and the public, governments can design regulations that respect privacy, data security and freedom of expression while helping to protect users from harm. Doing so is the only way to make sure that the Internet works for everyone.

There is a modern roadway stretching from central Hargeisa, the capital of Somaliland in the Horn of Africa, to the partially recognized state’s Egal International Airport. Emblazoned on a gold plaque marking the road’s inauguration in July last year, just below the flags of Somaliland and the Republic of China (ROC), is the road’s official name: “Taiwan Avenue.” The first phase of construction of the upgraded road, with new sidewalks and a modern drainage system to reduce flooding, was 70 percent funded by Taipei, which contributed US$1.85 million. That is a relatively modest sum for the effect on international perception, and
At the end of last year, a diplomatic development with consequences reaching well beyond the regional level emerged. Israeli Prime Minister Benjamin Netanyahu declared Israel’s recognition of Somaliland as a sovereign state, paving the way for political, economic and strategic cooperation with the African nation. The diplomatic breakthrough yields, above all, substantial and tangible benefits for the two countries, enhancing Somaliland’s international posture, with a state prepared to champion its bid for broader legitimacy. With Israel’s support, Somaliland might also benefit from the expertise of Israeli companies in fields such as mineral exploration and water management, as underscored by Israeli Minister of
When former president Tsai Ing-wen (蔡英文) first took office in 2016, she set ambitious goals for remaking the energy mix in Taiwan. At the core of this effort was a significant expansion of the percentage of renewable energy generated to keep pace with growing domestic and global demands to reduce emissions. This effort met with broad bipartisan support as all three major parties placed expanding renewable energy at the center of their energy platforms. However, over the past several years partisanship has become a major headwind in realizing a set of energy goals that all three parties profess to want. Tsai
An elderly mother and her daughter were found dead in Kaohsiung after having not been seen for several days, discovered only when a foul odor began to spread and drew neighbors’ attention. There have been many similar cases, but it is particularly troubling that some of the victims were excluded from the social welfare safety net because they did not meet eligibility criteria. According to media reports, the middle-aged daughter had sought help from the local borough warden. Although the warden did step in, many services were unavailable without out-of-pocket payments due to issues with eligibility, leaving the warden’s hands
