Understand the Basics of Digital Signatures When I started working with PDFs, I remember wanting to send the file to someone and ensuring that the document didn’t change and that content couldn’t be removed, among other things. So I started looking into the different security features that can be added to a PDF in Acrobat. There seemed to be about a billion at first glance. Actually, generally, security on a PDF can be broken down into a few options found within Acrobat X: • Password security (the simplest method) • Digitally signing a document • Certifying a document • Using Adobe LiveCycle Rights Management Password security is the security method most of us use when we want to ensure that content can’t be copied from our PDF (among other things). Certifying a document via encryption indicates that you approve of the contents of the PDF, and only the first person to sign the document can certify it (usually the initiator). When you certify the document, you can also specify what changes can be made to the document in order for it to remain certified. Digitally signing a document can be simple or complex, depending on how you approach it and what you expect from it.

Members of AATL are Trust Service Providers (TSPs) and Certificate Authorities (CAs) that provide certificate-based IDs and timestamping services to consumers and/or enterprises. In turn, those customers are enabled to sign, certify, timestamp, and validate documents using Adobe Document Cloud software solutions. Each of these providers has met strict criteria before being accepted into the program.
