ADSS Enterprise Server

Overview

ADSS (Advanced Digital Signature Services) Enterprise Server offers enhanced digital signature creation, verification and time-stamping services for business applications needing to trust documents and data. It ensures that the applications have access to easy to use trust services and ADSS Server off-loads the often forgotten overheads of authorisation decisions, detailed policy definitions, auditing logging, billing and other management tasks. ADSS Enterprise Server has been designed for internal Enterprise use as well as External multi-party use and for Managed Service Providers.

Features & Benefits

ADSS Server has been built to satisfy a wide variety of business trust services, which have various data and signature formatting requirements. The many options are controlled through security policies that make ADSS Server easy to use via any or all of its interface types:

• Web Services interface (XML/SOAP) – Java & .Net API client code is available
• Watched Folders using the ADSS Auto File Processor application
• Email using Secure Email Server
• Web gateway using ADSS Gateway

Almost any business application can use ADSS Enterprise Server with ease, the central policy driven controls ensure that applications are able to easily use high level security services to sign, counter-sign, timestamp and verify the following document and data types:

• PDF Documents
• Any file type (e.g. Word, Excel, AutoCAD, PDF, Project, Visio, etc)
• XML data
• Web-form data

These document types can be signed, verified, validated and also be historically verified at a future point in time. ADSS Server even includes an in-built CA module so that there is no need to deploy a CA or use an external CA service provider. Signing options include:

• Corporate key signing – for documents receipts, invoices, etc.
• Multi-user signing using keys generated and stored on the ADSS Server
• Multi-user signing on the client-side using local keys and certificates on smart cards or USB tokens

The last point shows that using ADSS Enterprise Server and the ADSS GoSign applet, end-users can sign documents directly from the browser (using soft keys, smart cards or USB tokens) without the need for installing a local signing application on the desktop. The GlobalTrustFinder web-site includes a live ADSS GoSign client-side signing demonstration. Based on an example ‘purchase order’ application, it uses ADSS Server with its optional PDF Signing module to sign a document. Click here to view this demonstration.

ADSS Server is modular product - only the module required need be licensed. This provides a flexible yet cost-effective solution, with in built investment protection since other modules can be added later to support future business needs. To make it easy to find on Internet searches it is also branded under the following marketing names PDF Signer Server, File Signer Server and XML Signer Server.
