Digitally Sign Documents

Digital signatures are an easy-to-use, non-forgeable way to authorize electronic documents and transactions, and eliminate the need to print and manually sign and route paper documents. Today, most countries promote digital signing, and have even adapted legislation and regulations that recognize the legality of digitally signed documents.

CoSign® is an easy-to-use digital signature solution that integrates seamlessly with all major document management solutions such as Microsoft® Word, Excel®, Adobe® PDF, and more. This makes it easy to apply your personalized digital signature to any common file format you use without having to print it out, and also allow third or external parties to verify your signature for authenticity and integrity. CoSign automatically invalidates a digital signature if any changes are made to the document after signing, thereby protecting against information tampering, and ensuring signer authenticity and accountability, data integrity and non-repudiation of electronic documents.

Using CoSign to digitally sign documents in Microsoft® Word is simple. After you install the CoSign application, a CoSign Digital Signature ribbon is added to the menu bar. To sign a document, just click “Sign with CoSign”. You can also create a digital signature field anywhere on the document by simply clicking on the desired area of the document, and then clicking the “Add Signature Field” button. Afterwards, digitally sign by simply right-clicking and selecting “Sign”.
