The legal process used by law enforcement to access data will differ depending on what type of data is being sought. Generally speaking, the law grants greater privacy protections to data that reveals the content of communications. While data about the communications, such as the sender and recipient of a message, is deemed to be less private and therefore easier for law enforcement to obtain under the law. Let's look at what different categories of data the law distinguishes. Different jurisdictions will use different terminology for these different types of data, but most laws follow a general pattern. To make things clear, we will use the terminology set out in the Council of Europe Cybercrime Convention. Subscriber information is considered to be the least privacy intrusive and includes any data held by service providers that relates to the type of service, the subscribers identity and contact information, billing information, and any equipment installed by the service provider.

The next type of data is considered more private but not as private as content data. This is traffic data. Traffic data is the data about a communication. It can include the origin and the destination of a communication, it's route, time, date, size, duration, and type of service. Sometimes people refer to this as the envelope data. Back in the days before phone and internet communications, an envelope could reveal the sender and recipient and the date and place that the letter was posted. These days, this envelope information is now in what is called a packet header for internet communications. This packet header is the information that computers generate about the communication in order to communicate the email to another computer. This contains the IP addresses of the sending and receiving computers, and what type of information is inside such as an email, a webpage, or a picture. Content data is of course the content of the communication. Be that an email, message, webpage, social network friend request, and so on. Sometimes it can be hard to neatly identify what data is traffic data and what data is content. For example, is a subject line of an email content or traffic data? Let's look at the example of a web address. The top-level web address seen here in highlight, is considered to be communications data or an internet connection record by the UK Investigatory Powers Act. In other words, it's traffic data. But the rest of the web address reveals exactly what the data subject has viewed. In this case, research papers on data protection in the Cloud. Thus, the IPA considers the rest of the web address to be content data because it reveals the content of the webpage. So what does this mean in practice? Does the data subject's internet service provider only provide the top-level web address to law enforcement? Or does the ISP require a warrant and consider all webpages to be content data? These are the types of issues that will arise when different types of data require different legal processes. But in practice, it can be difficult to distinguish.
