Digital Signatures with Activity Factory

Digital Signatures are basically an electronic equivalent of handwritten paper-based signatures, but it is much more powerful and secure than its traditional counterpart. It allows secure electronic approvals, replacing tedious paper-based processes. It also provides three core benefits: Non-repudiation, signer authentication, and data integrity. 

Activity Factory has been proven to be DPA compliant and has reduced approval time significantly. It supports two types of digital signing:


Document Cryptographic Hash 



Digital Signatures from a 3rd Party Provider 

Document Hash

Activity Factory adds a signature page and calculates the Cryptographic HASH of the file.

A HASH is a mathematical algorithm that calculates the file bits into a fixed string value (HASH). It is a one way calculation and cannot be inverted.

So when someone tampers with a document it will result in a different HASH value.

3rd Party Digital Signatures

3rd Party Digital Signatures are recommended as they are validated by a 3rd Party Provider and is globally accepted.

Activity Factory Digital Signatures are provided by our partner Global Sign.

Purchase Order Paperwork and Efficiency

Physically signing paper is inefficient, mainly because a document needs to be brought to the person authorizing the transaction.

Electronic signing removes that barrier, allows transactions to be done from the phone or a computer, anywhere in the world anytime of the day. Apart from that paper copies and filing costs are removed, opens up more space and is great for the environment.

The purpose of Signatures are to validate and authorize a transaction, and is obviously done by physically signing the document.

Electronically Signing documents done by a click of the mouse or by merely tracing the signature using a finger or a stylus pen follow the same principle and are exposed to tampering.

Hence, the need for Cryptographic approaches to digital signing.

Usernames and passwords are not enough

We strongly recommend the use of One Time Passwords (OTP) when moving into digitally signing documents.

OTP provides an added layer of security by using a users mobile phone to ensure the identity of the user.
