Protecting User Privacy is Not Optional

June 30, 2022

Online services face increasing public pressure to protect their visitors' private data. This is reflected in many new data privacy laws around the world.

Headlines tell us daily of new data breaches and enormous losses of sensitive Personally Identifying Information ("PII"). While the need to protect user data from cybercriminals is increasingly obvious, online services must also ensure their policies, partners, and practices minimize data collection and safeguard PII.

In this article we’ll look at how hCaptcha helps to protect PII from outside attackers and unintentional abuse within your organization.

How is User Privacy Compromised?

Outside Attacks on User Privacy

Online fraudsters use many techniques to discover, steal, abuse, and otherwise compromise user privacy. The use of bots to provide automation is a vital and common ingredient among these techniques. Because bots are so heavily used by attackers,  their very presence is a key indicator of a potential attack that could compromise user privacy.  To understand this, let’s look at how fraudsters operate to steal and exploit PII. Two methods are common: Account Takeovers (ATO) and New Account Fraud.  

ATO Attacks - A Direct Assault on User Privacy

In an ATO attack, fraudsters often use an approach called credential stuffing. The technique utilizes bots to automatically inject stolen user IDs and passwords into login forms. The goal is to give the attacker access to, and control over user accounts.  Successful ATO operations can be very damaging to victims, who not only lose control over their accounts, but also their PII. Depending on the type of site, fraudsters can obtain vast amounts of sensitive personal data with each successful login.

New Account Fraud - Abusing Previously Obtained Private Information

New account fraud, or fraudulent account registration, is another common attack. Bad actors obtain stolen personal data, including login credentials via the dark web or another unsavory channel. As with an ATO attack, these bad actors then use bots to automate their attack, rapidly filling out new account forms with the stolen PII.

The fraudulent accounts are used to make purchases, generate spam, spread misinformation, distribute malware, scrape PII from social media and other sites, and perform a host of other nefarious deeds. Any of these activities can be extremely harmful to the victim. 

Automation: A Key Ingredient for ATO, New Account Fraud, and Other Attacks

As described in the ATO and New Account Fraud examples above, automation is a key tool in an attacker’s arsenal. Without bots, many cyber crimes are too labor intensive to be profitable. Because bots are readily available, relatively inexpensive, and don’t require a great degree of skill to use, fraudsters turn to them to carry out their attacks.

Due to the prevalence of bots in cybercrime attacks, it’s critical for website applications to quickly and accurately differentiate between malicious bot and legitimate user traffic. 

Business Abuse of PII and User Privacy

In the section above, we discussed how PII can be illegally obtained by criminals attacking web applications, but PII can also be abused by businesses and other organizations. This occurs when web applications (including partners or vendors) capture, retain, transmit, or otherwise leverage PII without the user’s knowledge or express consent. 

In this scenario, the PII is typically stored in the form of cookies on the user’s device, and then transmitted to the website for processing (and sometimes to partners or other third party services the website is utilizing). The information identifies the user and contains data associated with that individual. 

Your address, sex, age, the language you speak, the internet searches you’ve made, the articles you’ve read, how many clicks you made on a page, site passwords and more are often stored within these cookies. 

Although this personal information is obtained by web applications themselves and not by outside criminal attackers, the data still contains PII, and many view its retention and use as an invasion of privacy. This is especially true when that information is transferred to other organizations without the user’s knowledge or consent. 

The transmission of PII to partners or outside services is a specific concern for websites  that are utilizing bot detection technology. This is somewhat ironic because bot detection is a fundamental solution for detecting PII abuse, and yet many bot detection systems in use today transmit PII between online properties and third-parties for processing. This practice perpetuates the use of PII and may fail to comply with emerging privacy laws in some countries.

hCaptcha processes data close to the user in more than 250 locations and has always focused on de-identifying, discarding and aggregating all data as rapidly as possible, ensuring maximum compliance with privacy laws via our privacy-first design. hCaptcha Enterprise offers additional safeguards with features like Secure Enclaves and Zero-PII blinding. We are much more interested in technical guarantees than legal ones, and lead the field in privacy-preserving machine learning for security use cases.

The Growing Demand for Digital Privacy

With the prevalence of criminal theft and organizational abuse of PII, the public is taking a much harder stance on privacy protection.  

Do Not Track, Surveillance Capitalism, Data Privacy Day (or Data Privacy Week starting in 2022) – these and numerous other taglines, mottos, and phrases continue to underscore the evolving attitudes and trends in protecting digital privacy.

Rapidly Evolving Privacy Laws  

Driven by demands from individuals and organizations, governments have stepped in to protect private information, passing numerous legislative mandates to restrict its use. 

In general, the laws prohibit PII from being collected, retained, or transmitted unless the data is critical to the service being offered, the user has been informed about how their data will be used, and has given consent or accepted that the data processing is necessary for the operation of the service.

Some of the more significant privacy laws affecting online services include the following: 

  • GDPR: The General Data Protection Regulation is a set of online privacy laws protecting residents of the European Union. Any organization that interacts with residents of the EU must comply with the directive.
  • CA CCPA: The California Consumer Privacy Act regulates the sale of personal information of California residents. This affects everyone doing business with California residents.  
  • LGPD:  Brazil's first comprehensive data protection regulation, which broadly aligns with GDPR principles.
  • COPPA: Mandates that websites that collect PII from children must obtain parental consent before collecting, using, or disclosing children's personal information.
  • CalOPPA: requires that a privacy policy identify both the categories of personal information that a website collects and the categories of third-party persons or entities with whom the website operator may share that personal information.
  • PIPEDA: Canada’s Personal Information Protection and Electronic Documents Act.
  • PIPL: China’s online privacy legislation, similar to Europe’s GDPR but containing additional requirements around data locality.

In addition to these and other existing mandates, new privacy legislation is being developed around the world and the trend shows no sign of slowing.

As governments tackle privacy, it is imperative for businesses to ensure that their practices are in compliance with the numerous existing regulations and those expected to go into effect in the near future.

How hCaptcha Protects User Privacy 

Bots are nearly ubiquitous with attacks that compromise user privacy. hCaptcha Enterprise was developed specifically to mitigate automated threats while protecting user privacy. A unique edge-first privacy-preserving machine learning approach rapidly differentiates between bad actors and legitimate human traffic while rapidly discarding PII. This allows organizations to protect data from cybercriminals and potential business abuse, while complying with privacy regulations.
