Case Study: Swisscom Trust Services achieves legally valid digital PDF signing with iText

Swisscom Trust Services powers remote PDF signing for 5+ years with iText

Swisscom Trust Services, a leading European trust service provider, faced the challenge of integrating legally binding, qualified electronic signatures and timestamps into PDF documents for their partners' digital workflows. They needed a solution to power their Signing Service, a cloud-based offering for both on-demand and mass signatures that complies with strict EU (eIDAS) and Swiss (ZertES) regulations.

Using the iText 7 Core PDF library, Swisscom built the backbone of its PDF signing engine. The iText solution provided an abstraction layer, allowing Swisscom's customers to easily generate digitally signed PDFs without needing deep knowledge of PDF specifications. The result is a highly scalable and secure service that handles high volumes of documents, integrates with other Swisscom digital identity services, and enables partners to offer fully digital, paperless processes to their end customers.
