【終了】香港、警察から求められればパスワード等を提供して中身にアクセスできるようにしなくてはならないだってさ。
Hong Kong has reportedly introduced a new rule allowing police to demand passwords and access to digital devices like smartphones and PCs. This has sparked widespread shock and concern online, with many questioning the end of Hong Kong's freedom and the concept of privacy.
Viewed as a significant step back for Hong Kong's 'One Country, Two Systems' under the guise of national security, it marks a worrying reinforcement of digital surveillance on individuals. The news has caused global ripples, urging us to reconsider digital privacy and data protection in this era.

Hong Kong National Security Law
The Law of the People's Republic of China on Safeguarding National Security in the Hong Kong Special Administrative Region, enacted on June 30, 2020, profoundly transformed Hong Kong's long-standing high degree of autonomy and freedom, symbolized by the 'One Country, Two Systems' framework. This law aims to strictly curb four types of acts: secession, subversion, terrorist activities, and collusion with foreign forces. However, its ambiguous scope of application and extensive investigative powers have drawn strong criticism from the international community. The recent 'demand for passwords and other access' is interpreted as part of the broad investigative powers stipulated in Article 43 of this law, allowing police to request interception of communications, access to personal electronic devices, and provision of information in matters concerning national security. Since its enactment, democratic activists and journalists in Hong Kong have been successively arrested and prosecuted, severely restricting freedom of expression and assembly. It has also significantly impacted business operations, increasing compliance risks related to data storage and employee communication surveillance, forcing many international companies to re-evaluate their business strategies in Hong Kong. This casts a dark shadow over Hong Kong's status as an international financial center and its rule of law.
Data Privacy (Personal Information Protection)
Data privacy refers to an individual's right to prevent their digital information (communication history, browsing history, location data, private messages, health information, etc.) from being collected, used, or disclosed without their consent. Many countries and regions, such as the EU with GDPR (General Data Protection Regulation) and California with CCPA (California Consumer Privacy Act), are advancing legislation to protect individual privacy rights. Hong Kong also once had relatively robust personal data privacy ordinances that respected citizens' privacy. However, with the implementation of the Hong Kong National Security Law, the level of protection may significantly recede in matters concerning national security. The police's ability to demand passwords and access to encrypted data means that highly private information, such as individuals' communication secrets, thoughts, and beliefs, could come under official surveillance. This suggests that a widespread surveillance system, similar to what is already implemented in mainland China, could be deployed in Hong Kong, leading to a significant chilling effect on citizens' digital activities. For businesses, the responsibility for protecting customer and employee data becomes heavier, and they face serious challenges in how to respond to official data disclosure requests and manage international data transfers. Users are also increasingly taking self-protective measures, such as using VPNs and migrating to end-to-end encryption tools.
Encryption and Backdoors
Encryption is a technology that transforms data content to make it unreadable to anyone other than authorized parties, essential for maintaining communication secrecy and data confidentiality. 'End-to-end encryption,' in particular, is a robust method that ensures no one can decipher the content of communication from sender to recipient, used by messaging apps like WhatsApp and Signal. The police's demand for passwords and access in this context is precisely aimed at decrypting such encrypted data. On the other hand, governments and law enforcement agencies sometimes demand IT companies to install 'backdoors' (secret access points accessible only to the government) in encryption systems or provide master keys, citing reasons like criminal investigation or national security. However, once installed, backdoors pose an extremely high risk of being exploited not only by governments but also by malicious hackers, thereby threatening the security of all users. For this reason, many security experts and IT companies strongly oppose them. When Apple and the FBI had a dispute over unlocking an iPhone in 2016, Apple refused to install a backdoor, citing user privacy protection. While Hong Kong's situation differs from corporate backdoor demands in that the police directly request password disclosure from users, it is fundamentally the same in enabling access to individuals' encrypted information. Users must use stronger encryption technologies and carefully consider the legal regulations of the service provider's country and the company's policies if they store data on cloud services.
