Mobile signatures
The use of mobile devices to access business systems has now become commonplace. The ability to view and digitally sign documents from a mobile device is an essential requirement when choosing a signing platform. However what is often not understood is that there are different levels of mobile signing, with varying degrees of what is performed on the mobile device:
The mobile device is used to initiate the signing process – the signing key is located on the server and the signature takes place there, however, the user initiates the process from their mobile device.
The mobile device is used to authorize the signing process – this is where the user’s mobile is sent a One-Time Password (OTP) code as a form of authentication.
The mobile device is used to actually sign the document – this is the true form of mobile signing, i.e. the user’s signature key actually resides on the mobile device and the document signature is created on the mobile device.
