📌 Token Binding Summary
Token Binding is a security technology that helps to prevent certain types of attacks on web sessions. It works by linking a security token, such as a session cookie or authentication token, to a specific secure connection made by a user’s browser. This means that even if someone tries to steal a token, it cannot be used on another device or connection, making it much harder for attackers to hijack sessions or impersonate users. Token Binding requires support from both the user’s browser and the server hosting the website or service.
🙋🏻♂️ Explain Token Binding Simply
Imagine you have a ticket to a concert that only works if you show up with your own ID. If someone else steals your ticket, it will not work for them because it is linked to your identity. Token Binding does something similar for online security by making sure digital tickets (tokens) only work on your device and not if copied by someone else.
📅 How Can it be used?
Token Binding can be added to a web application to stop attackers from reusing stolen authentication tokens.
🗺️ Real World Examples
A banking website implements Token Binding so that when a user logs in, their session token is bound to their browser. If an attacker tries to steal the session cookie and use it from a different browser or device, the bank’s server will reject it, preventing unauthorised access to the account.
An online retailer uses Token Binding to protect its customers during checkout. If a cybercriminal attempts to hijack a user’s shopping session by copying their authentication token, the retailer’s system detects that the token is not coming from the original secure connection and blocks the attempt.
✅ FAQ
What is Token Binding and how does it help keep my online sessions safe?
Token Binding is a security feature that makes it much harder for attackers to steal your session or pretend to be you online. It works by linking your session tokens, like cookies, directly to your browser connection. This means even if someone manages to get hold of your token, they cannot use it on another device or browser, keeping your sessions much safer.
Do I need to do anything special to use Token Binding when browsing the web?
As a regular user, you usually do not need to do anything extra. Token Binding works in the background if both your browser and the website you are visiting support it. Most of the time, it is up to website developers and browser makers to enable this feature for you.
Why is Token Binding not used everywhere on the internet?
Token Binding needs both the website and your browser to support it. Some websites and browsers might not have added this support yet, which means the technology is not available everywhere. Over time, as more sites and browsers add support, it will become more common.

Adversarial Example Defense
Adversarial example defence refers to techniques and methods used to protect machine learning models from being tricked by deliberately altered inputs. These altered inputs, called adversarial examples, are designed to look normal to humans but cause the model to make mistakes. Defences help ensure the model remains accurate and reliable even when faced with such tricky inputs.
Secure Multi-Party Analytics
Secure Multi-Party Analytics is a method that allows several organisations or individuals to analyse shared data together without revealing their private information to each other. It uses cryptographic techniques to ensure that each party's data remains confidential during analysis. This approach enables valuable insights to be gained from combined data sets while respecting privacy and security requirements.
Data Pipeline Automation
Data pipeline automation is the process of setting up systems that move and transform data from one place to another without manual intervention. It involves connecting data sources, processing the data, and delivering it to its destination automatically. This helps organisations save time, reduce errors, and ensure that data is always up to date.
Digital Transformation Governance
Digital transformation governance refers to the set of rules, processes, and structures that guide how an organisation manages and oversees its digital transformation efforts. It ensures that digital changes align with business goals, use resources wisely, and manage risks effectively. Good governance helps teams work together, measure progress, and make informed decisions about technology and data.
Resistive RAM (ReRAM) for AI
Resistive RAM (ReRAM) is a type of non-volatile memory that stores data by changing the resistance of a special material within the memory cell. Unlike traditional memory types, ReRAM can retain information even when the power is switched off. For artificial intelligence (AI) applications, ReRAM is valued for its speed, energy efficiency, and ability to process and store data directly in the memory, which can make AI systems faster and more efficient.
