Device Bound Session Credentials (DBSC) is a mechanism introduced by Google to combat cookie theft. It ties authentication data to specific devices, rendering stolen cookies useless.

2.How does DBSC work?

When a browser starts a new session, DBSC generates a unique key pair on the device, with the private key securely stored. Web servers can associate sessions with these keys using the DBSC API.

3.Why is cookie theft a problem?

Cookie theft poses a risk as malicious actors can steal cookies from users' devices, potentially accessing sensitive data associated with online accounts.

4.How does DBSC protect privacy?

Each session has its own unique key, preventing correlation between sessions on the same device. Only session-specific public keys are sent to servers for verification, protecting user privacy.

5.Who will benefit from DBSC?

DBSC aims to benefit all users by enhancing security in web browsing, particularly those concerned about privacy and data security.

6.Will DBSC be widely adopted?

Google plans to support DBSC for a significant portion of desktop users initially. Interest has also been expressed by other industry players, potentially leading to broader adoption.

7.Is DBSC compatible with other browsers?

Google is developing DBSC as an open standard, with the goal of making it compatible with various web browsers.

8.How does DBSC relate to Google's cookie phase-out?

DBSC aligns with Google's plan to phase out third-party cookies in Chrome, providing an alternative method for authentication and session management.

9.Where can I learn more about DBSC?

More information about DBSC can be found on Google's Chromium Blog and the project's GitHub repository.

Google's Game-Changing Anti-Hack Weapon: Say Goodbye to Cookie Theft

Google’s Game-Changing Anti-Hack Weapon: Say Goodbye to Cookie Theft

Google is addressing the problem of cookie theft by introducing a new approach called Device Bound Session Credentials (DBSC). This strategy aims to render stolen cookies ineffective by linking authentication data to specific devices. Here are the key points:

Issue: Malware can steal cookies from users’ devices, potentially compromising sensitive data.
Solution: DBSC binds authentication sessions to individual devices using cryptographic keys, preventing stolen cookies from being useful.
How it Works: When a session begins, the browser generates a unique key pair on the device, with the private key securely stored. Web servers can associate sessions with these keys using the DBSC API.
Privacy Protection: Each session has its own unique key, ensuring that sessions on the same device cannot be correlated. Only session-specific public keys are sent to servers for verification.
Implementation: Initially, Google aims to support DBSC for approximately half of desktop users, with potential interest from other industry players.
Open Standard: Google is developing DBSC transparently on GitHub, with the goal of making it a universal web standard.
Alignment with Cookie Phase-Out: DBSC aligns with Google’s plan to phase out third-party cookies in Chrome and is currently undergoing testing.
Future Plans: Google plans to extend DBSC to enhance security for Google accounts, Workspace, and Cloud customers.
Comparison: DBSC is presented as a more privacy-friendly alternative to past attempts such as Intel’s unique processor serial number.

In summary, DBSC reflects Google’s efforts to strengthen security and privacy in web browsing by addressing cookie theft.
