Paris, France, July 29, 2025 - Didomi is proud to introduce a major upgrade to its Consent Management Platform with its new Didomi Consent String (DCS) and a cryptographically secure Signature feature. Together, they represent a significant leap forward in ensuring the performance and integrity of consent collection at scale.
As part of its ongoing commitment to delivering state-of-the-art, industry-leading solutions to clients, Didomi is introducing two innovations that will drive its products and services forward: the Didomi Consent String (DCS) and the Didomi Signature feature.
A faster, lighter, smarter consent string and new standard for consent integrity
The Didomi Consent String (DCS) is a lightweight and efficient alternative to the traditional JSON-based format for storing user consent.
By switching to a binary structure, DCS reduces the size of stored consent data to under 2KB, aiming to improve website performance by reducing the size of the Didomi token.
The Signature feature adds a cryptographic seal for each consent string, verifying that the consent was collected on the correct domain and hasn’t been altered downstream. This directly addresses a longstanding vulnerability in the adtech ecosystem: until now, consent strings could be modified in the supply chain (intentionally or not) without any clear trail or proof.
With Signature, organizations can now confidently demonstrate the authenticity and origin of consent records. Whether during a regulatory audit, internal compliance check, or a dispute with partners, the ability to prove the integrity of a user’s consent is now just a few clicks away.
“In today’s privacy landscape, collecting consent is just the start. You need to be able to prove it, clearly, quickly, and without slowing anything down. That’s exactly what Signature makes possible.
- Jenn Buckingham, Product Marketing Manager at Didomi
Built for privacy leaders, publishers, and enterprise-grade scale
These two new features are particularly impactful for:
- Privacy and compliance teams seeking verifiable consent records for legal and regulatory purposes.
- Publishers relying on trustworthy signals in their advertising supply chain.
- Enterprise customers operating in highly regulated industries or under frameworks such as the IAB’s Transparency and Consent Framework.
By delivering both performance and trust, DCS and Signature provide the peace of mind that privacy teams need without compromising speed or user experience.
Until now, the industry has lacked a standardized, lightweight, and secure method to ensure that consent data remains authentic throughout its lifecycle. Didomi’s latest innovation directly addresses this problem by providing customers with the tools to secure consent data from collection to audit.
We built DCS and Signature to give our customers what the industry was missing: a simple, verifiable way to prove consent integrity without slowing anything down. It’s a meaningful step forward for both performance and trust.
