Cookies: Courtroom Evidence Or Digital Privacy Concern?

Cookies are small text files that are placed on your computer by websites that you visit. They are used to make websites work more efficiently and to provide information to the owners of the site. While cookies do not harm your computer, they can be used to track your browsing behaviour and collect your personal data. As a result, there are cookie laws in place in many jurisdictions that require websites to obtain your consent before storing cookies on your device. These laws are designed to protect your privacy and prevent the misuse of your personal information. In some cases, the disclosure of certain data collected through cookies may even constitute a data breach. So, can cookies be used against you in a court of law? The answer is potentially yes, and it is important to be aware of your rights and the laws that govern the use of cookies in your jurisdiction.

Cookie laws in the US

Cookies are small data files that track user behaviour in a browser and are used to create tailored buyer profiles. They can be used for functions like remembering login details and items in a shopping cart, as well as for personalised advertising. While cookies can improve the user experience, they have also raised concerns about privacy and data protection.

In the US, there is no federal law regulating the use of cookies. However, this does not mean that cookies are completely unregulated. In the absence of federal legislation, several states have enacted their own cookie laws, including California, Virginia, Colorado, Utah, and Connecticut. These laws came into effect in 2023 and are largely similar, although there are some differences in how they define consumers, personal information, sales, and consumer rights.

For example, the California Consumer Privacy Act (CCPA) and the California Privacy Rights Act (CPRA) allow California residents to opt out of data collection and sales. The CPRA also requires businesses to obtain explicit consent to process, sell, or share personal information collected by cookies. Similarly, the Virginia Consumer Data Protection Act (VCDPA) grants consumers the right to opt out of data processing for targeted advertising, the sale of personal data, and profiling. The VCDPA also allows the Virginia Attorney General to take legal action to halt or prevent violations, in addition to imposing monetary fines.

The Colorado Privacy Act (CPA), which came into effect on July 1, 2023, applies to data controllers that process the personal data of at least 25,000 consumers or 100,000 consumers annually. It gives consumers the right to opt out of targeted advertising and sensitive data processing, and non-compliant businesses can face fines of up to $7,500 per infringement.

While these state-level laws provide some regulation, the lack of comprehensive federal legislation means that cookie laws in the US are not as stringent as those in the EU, as exemplified by the GDPR. Nevertheless, with an increasing number of states enacting data privacy laws, organisations must stay vigilant to ensure compliance with the various and evolving cookie regulations.

Cookie laws in the EU

Cookies are small text files that are placed on a user's computer by websites they visit. They are used to make websites work or work more efficiently, as well as to provide information to the owners of the site. Cookies can be used to track a user's browsing behaviour and send this data back to websites. This information can then be used for marketing purposes, which could mean that the user gets unsolicited advertising.

The EU Cookie Law, also known as the ePrivacy Directive, is a piece of privacy legislation that requires websites to obtain consent from visitors before retrieving or storing their personal information. It is a directive from the European Union that was intended to protect online privacy. The EU Cookie Law came into effect in 2002 and was amended in 2009. It is not a binding law but a guideline for EU member states to create their own laws. The ePrivacy Regulation is set to replace the ePrivacy Directive in the near future and will be binding on all member states.

The EU Cookie Law applies to all websites with visitors from the EU, regardless of where the business is located. This means that websites must comply with the EU Cookie Law if they have visitors from EU countries. The law dictates that website owners must inform users of the cookies they use and how they will be used. Website owners must also get prior consent from users to store the cookies on their devices and make it possible for users to opt out.

The General Data Protection Regulation (GDPR) also affects how cookies are used to collect information. It requires all multinational companies to provide an opt-in whereby website owners receive a user's permission to use cookies before they can be stored on a user's web browser. This gives users greater control over their data. Non-compliance with the GDPR may result in fines.

Cookie consent

Cookies are small text files that are placed on your computer by websites that you visit. They are used to make websites work more efficiently and to provide information to the owners of the site. Cookies can collect personal data from visitors on a domain and track their browsing habits. While cookies do not harm your computer, some people find them annoying because they cannot control what type of cookies are stored on their device.

To address this concern, cookie laws have been introduced to protect users' privacy and prevent the misuse of information collected by cookies. These laws require websites to obtain users' consent before storing cookies on their devices. This is known as cookie consent.

To comply with these laws, websites must provide a cookie consent banner or notice that informs users about the site's use of cookies and obtains their explicit consent to store these cookies on their devices. This banner should provide clear and precise information about the types of cookies used, such as preference, marketing, or analytics cookies, as well as what the cookies do and who may have access to the data collected.

In addition to global laws, there are also state-level laws in the United States, such as the California Consumer Privacy Act (CCPA) and the Virginia Consumer Data Protection Act (CDPA), which consider cookies as personal information and give consumers the right to opt out of the processing of their personal data for targeted advertising.

Cookies and data breaches

Cookies are small pieces of data stored on your computer by websites that you visit. They are used to recognise you when you return to a website and to remember your preferences, login information, and other settings. While cookies are not inherently harmful and can provide a more tailored browsing experience, they can also pose risks to your privacy and security.

Data breaches involving cookies, also known as cookie capture or session hijacking, occur when attackers gain unauthorised access to a user's cookies. This can happen through various methods such as packet sniffing, where attackers monitor unencrypted network traffic, or cross-site scripting (XSS), where attackers inject malicious scripts into websites to steal cookies. Once an attacker obtains a valid cookie, they can impersonate the user, gaining access to sensitive information and performing actions on their behalf without their consent.

To prevent data breaches and protect your online sessions, it is important to take certain measures. Using HTTPS is crucial, as it encrypts data transmitted between the user's browser and the web server, preventing eavesdropping or tampering. Additionally, consider using privacy software that masks your digital fingerprint and protects against invasive tracking techniques.

In terms of legal consequences, organisations that fail to adequately protect user data or maintain proper security measures may face fines or penalties under data privacy laws such as the European General Data Protection Regulation (GDPR) or state-level laws in the US, such as the California Consumer Privacy Act (CCPA) and the Virginia Consumer Data Protection Act (CDPA). These laws give users greater control over their data and require websites to obtain consent before storing cookies on users' devices.

Cookies and personal data

Cookies are small text files that are placed on a user's device by websites they visit. They are used to track visits and optimise browsing behaviour, as well as to store and process user information. This information can include significant amounts of data about a user's online activity, preferences, and location. Cookies can be useful for users, for example, by allowing websites to remember login details or items in a shopping cart. However, they can also affect user privacy, as they can be used to track and identify individuals or households and are, therefore, considered personal data under most privacy laws.

The European Union's General Data Protection Regulation (GDPR) and the ePrivacy Directive (also known as the EU Cookie Law) are two notable examples of legislation governing the use of cookies and the protection of personal data. The GDPR, in particular, classifies cookies as personal data and requires website operators to obtain consent from users before storing or retrieving information on their devices. This legislation also gives individuals the right to opt out of having their data sold or shared with third parties or used for targeted advertising. The EU Cookie Law, on the other hand, requires websites to provide clear and precise information about the cookies they use and how they will be used, as well as to obtain prior consent from users and offer an option to deny consent.

In the United States, while there are no federal laws specifically regulating cookies, state-level laws such as the California Consumer Privacy Act (CCPA) and the Virginia Consumer Data Protection Act (CDPA) consider cookies as personal information. The CCPA requires businesses to disclose the use of cookies and the data collected through them, while the CDPA gives consumers the right to opt out of processing personal data for targeted advertising, the sale of personal data, and profiling.

The impact of accepting or refusing cookies varies depending on the website and the user's preferences. Accepting cookies can provide improved website access and a more customised browsing experience. However, refusing cookies may limit functionality on certain websites or result in a less tailored user experience. Additionally, there may be concerns about the potential for third-party cookies to be abused or used for invasive online tracking. As such, it is important for users to understand the data collected by cookies and make informed decisions about consenting to their use.
