Data privacy violations and misuse pose serious threats in our increasingly digitized world. They affect individuals, as well as businesses and organizations of all kinds and sizes. In recent times, there have been several prominent examples of data privacy breaches. T-Mobile, a well-known telecommunications giant, experienced a data breach in 2022, which cost the company alone $350 million in customer payouts. Another data breach in 2023 impacted around 800 customers, with personal information such as contact details and social security numbers being stolen.
Cambridge Analytica, a British data analytics firm, was involved in a major scandal for unauthorized collection of data from Facebook users. The scandal came to light in March 2018 and had far-reaching implications on the debate surrounding data privacy and the influence of social media on democracy. Cambridge Analytica collected data from millions of Facebook users through an app called „thisisyourdigitallife,“ marketed as a psychological research tool. While only about 270,000 people downloaded and used the app, it was able to gather data from friends of those users, resulting in approximately 87 million affected individuals. As a direct consequence of the scandal, Cambridge Analytica shut down in 2018, and Facebook received an unprecedented $5 billion fine from the Federal Trade Commission in the United States for privacy violations. However, the impact of the scandal extends far beyond these immediate consequences and continues to resonate today.
Data privacy breaches have also occurred in the healthcare industry. Apria Healthcare, a US healthcare company, reported that nearly 1.9 million customers could have been affected by a data breach that occurred in both 2019 and 2021. PharMerica, a large pharmaceutical company, discovered that an unknown actor gained access to its systems in March and extracted personal data from 5.8 million individuals. The US government was also affected by a data breach exposing personal information of 237,000 government employees. Fast-food chains Pizza Hut, KFC, and Taco Bell, owned by Yum! Brands, fell victim to a ransomware attack exposing personal data. Suzuki, an automobile manufacturer, had to halt operations at an Indian factory due to a cyber attack, resulting in the production disruption of over 20,000 vehicles. Messaging platform Discord informed its users that their data may have been exposed by a malicious third party who gained access to a customer service representative. Even ChatGPT, an AI-based chat platform, experienced a data leak where customer credit card information and chat titles were exposed due to an error in the ChatGPT open-source library.
But what does all this mean for individuals, for you and me? Well, the danger lies in the nature of the data that is collected and potentially abused. In most cases, this includes personal and sensitive information such as names, dates of birth, social security numbers, identification data, health information, and, in some cases, even credit card information. This information can be utilized by criminals for identity theft, fraudulent activities, or acting on behalf of the affected individuals. In addition to the immediate threat of criminal activities, the collection and misuse of data can also have long-term effects. Companies that gather data can use it to create user profiles and display personalized advertisements. This can compromise privacy and lead to unwanted influence on consumer behavior.
However, the danger doesn’t just exist in the present but also in the future. With the advancement of technology, the threat of data privacy breaches is expected to increase. With more and more personal data being stored and shared online, and with increasingly sophisticated methods employed by cybercriminals, both individuals and businesses are becoming more vulnerable. It is crucial for us to be aware of these threats and take measures to protect our data, such as using strong passwords, enabling two-factor authentication, and being cautious about the information we share online.
Another approach to addressing the growing threats to privacy and data security is the utilization of decentralized networks. Unlike traditional centralized networks where user data is stored on central servers, decentralized networks are based on peer-to-peer technology. This means that the data is distributed across a network of computers and not stored in a central location. This makes hacking and data theft more challenging as there is no central point for an attack to focus on. One advantage of decentralized networks is that they can often better protect the anonymity and privacy of users. Since there is no central authority controlling the data, users often don’t have to disclose personal information to use the service. This reduces the risk of personal data being stolen or abused.
There are already a number of decentralized social networks, messaging apps, and other services following this approach. In addition to the social network Mastodon, which allows users to operate self-hosted decentralized instances, there are platforms like Odysee and Nostr. Odysee enables users to share various types of content, while Nostr utilizes an architecture similar to Twitter and supports encrypted direct messaging. In the realm of messaging apps, Signal is well-known for its focus on privacy and security. However, there are also others like Dust, which automatically deletes messages after a certain time, and Sense.Chat, an app based on the EOS blockchain that ensures a high level of privacy. In addition to these services, the Tor browser is another example of using decentralized technologies. It enables anonymous browsing through the use of onion routing technology. Furthermore, there are decentralized email services like ProtonMail and Mailchain, which give users control over their data and keep their emails private and secure.
However, it is important to note that decentralized networks also have their own challenges and risks. These include technical hurdles, difficulties in moderating harmful or illegal content, and the fact that the anonymity and privacy offered by these networks can also be exploited by criminals. Nonetheless, they provide a promising approach to mitigating the privacy and security issues associated with the use of Web 2.0.
